Hello. I'm looking for a specific video. It shows the Boston Dynamics robots dog with its Lidar sensor package. It's recorded at nighttime, in a forest, through nightvision imaging. One can clearly see the IR grid projected on the surrounding environment. Can anyone help me finding this video?

Good evening everyone,

I hope you can help me out here; I appreciate anyone who takes the time to respond.

I recently completed a flight over a specific area and collected both LiDAR data and images. However, I’ve just realized that the images are all rotated 180 degrees. Unfortunately, I can’t redo the flight, so I’m trying to figure out the best way to handle this situation.

Would it be advisable to rotate the images (for example, using Python) and then save them again? I’m a bit concerned about whether this rotation would alter any attributes or metadata associated with the images.

Alternatively, is it possible to adjust the exterior orientation parameters (EOP) without modifying the images themselves?

Any advice or insights on how to proceed would be greatly appreciated. Thank you in advance!

I know they can do with pointcloud data as .bin file format with [x,y,z,i] as data in bin. I have tried that and it works but I am trying to do it real time and not able to find many resources on it. Any help or suggestions would help.

Thanks to this subreddit for all the useful information from my last post.

I will be moving forward with my idea and need to purchase the equipment.

The main requirement I have is that the equipment work both in handheld mode and also on a UAV. Hovermap seems to be the product that keeps coming up as being the right solution, but I wanted to get this sub's input.

I also considered Elios 3 and Leica BLK360. I initially thought the DJI L2, but it can't be used in a handheld configuration.

I have a 2d Lidar Called STL27L :

and a IMU

iI have ubuntu 22 and Ros2 humble, i would like to establish this equip on drone. Now want to use this equipment to 3d map, i Would like to know what SLAM algorithm to use and how.

Hello guys, I'm trying to deeply learn and differentiate these technologies. Do you have suggestions on papers which do direct comparisons and establish pros and cons discussions?

Thank you in advance

Dose Anyone Know where I can find LiDAR Data of Middle East

Pretty cool story about LIDAR being used to discover an ancient city in Mexico.

I totally haven't just spent half an hour scouring google maps looking for clues 😅

Hello, I am a student from Japan.

I have a Livox Avia and would like to add color to the point cloud data captured with it using images from a camera. I am using a PC with Ubuntu 20.04.

My questions are:

1. Could you recommend a camera in the price range of 20,000 to 50,000 JPY (around $130 - $330) that works well for adding color to point cloud data and is available on Amazon?
2. I am not sure how to integrate the color from the camera images into the point cloud data. Could you provide a general outline or steps on how to do this?

I am new to using the Livox Avia and do not have much technical knowledge yet. Also, I apologize if my English is strange as I am using a translator. Any help or guidance would be greatly appreciated. Thank you!

I'll start by saying I know basically nothing about LIDAR other than the basics about what it is and can do.

I tend to get pretty far off the beaten path on a regular basis. I've been extremely fortunate in career to be able to travel while working.

I enjoy photographing abandoned, forgotten and/or hard to reach places. I am eligible to get a Masters in GIS at basically no cost.

I am considering getting professional drone pilot training, a LIDAR capable drone like DJI L2 and possibly a Matterport system. I am aware that this equipment is not cheap.

I would like to LIDAR/Matterport scan locations I visit and make the information publicly available. As an example, in central Missouri where I live currently, there are a few mills from the turn of the century. I would love to scan them with LIDAR and Matterport, and then make that information available to the public.

So I have a couple questions.

1. other than self hosting the data, are there ways to "open source" the data like giving it to USGS or something similar?
2. is something like a DJI L2 on a Matrice 350 RTK a decent option or should I be looking at other equipment?
3. if I wanted to donate/volunteer my time, energy and equipment to studies (think university professors leading a dig somewhere), does anyone know if there's a centralized "I need help with a cheap LIDAR scan" forum or similar?

Hi everyone,

I’m running into a problem with Terrascan when I use the “Draw Horizontal Section” tool. Instead of zooming in on the area where I’m creating the section, the software zooms out and shows the entire point cloud, which isn’t what I want.

1. Draw Vertical Section:

I'm using Microstation, and it's default 3D seed file.

Is there any setting which causing this?

Many thanks,

Hey everyone! 👋

I wanted to start a discussion about the LiDAR (Light Detection and Ranging) industry and its rapidly expanding role across various sectors. If you're curious about what LiDAR is and why it’s becoming increasingly important, here’s a quick overview:

In October 2023, FARO announced the release of the FARO Orbis Mobile Scanner, a groundbreaking advancement to redefine 3D reality capture. Orbis is the first to market a hybrid SLAM scanner that can be used for mobile and stationary data capture in one device. It offers local or cloud-based data processing and collaboration. The product is the latest evolution in FARO’s industry-leading Simultaneous Localization and Mapping (SLAM)-enabled LiDAR technology.

In April 2023, Teledyne Optech introduced the marine lidar sensor, CL-360 for marine applications. This lidar sensor can be seamlessly integrated with high-resolution multibeam systems and the CARIS Ping-To-Chart workflow, allowing full above and below-water image capture with survey-grade accuracy in a single workflow.

According to marketsandmarkets research, LiDAR Market worth $3.7 billion by 2029, Growing CAGR of 18.2%

The LiDAR market is projected to grow significantly, driven by increasing demand for accurate mapping solutions across industries.

What do you think about the potential of LiDAR technology? Have you seen any interesting applications or innovations lately? Let’s share our thoughts and insights!

Mobile mapping / reality capture research

Hi 👋 I’m a current graduate student conducting research on how people with careers in surveying, architecture, and construction are using mobile mapping / reality capture in their projects. If you’re feeling kind, I would love to learn more about how you’re adopting new technologies to complete your work 🙂

Hello, I’m an archaeologist and I’m working with a lidar dataset I got from a topographic company for a research I’m doing in a site bellow a rainforest. They did a good job classifying the points into terrain and vegetation, and I have a pretty good image from the archaeological site bellow the thick canopy. However, I’d like to know where can I find resources to help me reclassify the dataset between vegetation, terrain, and structures. I’d like to know this because the site is located over some hills, and I want to calculate some volumes on the constructions, but with the dataset classified as it is the hills and the buildings kind of overlap. I could ask the topographers to do it but they will probably charge me hehe, and I want to also teach myself how to do this type of work. I’ve started to use cloud compare, as it’s a free software, but anyone has any suggestions to where I could start, I’ll really appreciate it!!

Hello,

I am a master's student in architecture. I'm currently working on a historical building, part of the industrial heritage. I'm trying to get surveys & scans via drones. I do not know how to operate the drones but I got some help from a surveying engineer, only problem is he doesnt have any experience or idea about importing the said files to arcihtectural programs, such as Autocad or Recap. Recently, he sent me the scan results, bunch of files with a lot of formats. I tried to get some info on the net, asked GPT and all but I cant efficently import these files to Autocad. I've already finished half of the surveying process of the structure so I'm not really in a position to change the main software that I'm using.

I need help with importing the scan to Autocad. I have no idea about the formats except .las and those in this case seems to have something missing. 2 of the .las files seem identical and their quality is kinda low & has missing stuff in it. 3rd one is all gray. The engineer who helped me assured me that the scan results look good if you use all the files together (somehow). BTW I've learned that Pix4D was the software that been used for the lidar by the engineer.

I've shared the file informations as images. I'd be grateful if anybody could guide or inform me what to do - how to do it since I'm stuck at this point.

Hey guys, I posted about this settlement already, but I just found out that they are accepting late claims and you can still file to get payment even if the deadline has passed.

So for the newbies: back in COVID times, Velodyne issued a press release stating that its founder and its CMO were under investigation and removed after it turned out that they "lacked respect, honesty and integrity" with the directors and other main faces. 

After this news, VLDR dropped, and investors filed a lawsuit against them. And recently, they decided to pay a $27.5M settlement to resolve this scandal. And even though the deadline already passed, they are taking late claims on this. So if you were one of those damaged investors, you can check it out.

Hope it helps!

Looking to purchase Ouster Rev 6 in bulk, new or certified refurbished.

Is it possible to use an Pandar 40P to map a building site in/outdoors? See that they go for 300$ on eBay. Thinking of adding some stereo cameras to get a decent diy solution

Anyone who have done this project or know this field?, I watched many YouTube videos and I am still brainstorming these past few days how to execute it in ubuntu terminal via ROS2 Humble software. Can any one know the the requirements needed will i need raspberry pi or other components and also the step by step process and code that I needed. I am planning to mount it on a Stepper motor so that my 2d rp lidar s2 can have the mobility to scan attaining the 3d point cloud. Is there anything the easiest alternative software aside from the ROS2 (rviz)

I've recently purchaced a decent Lidar camera and I have no prior experiance of Lidar or laser scanning. the software it comes with is very user friendly so no issue there but I'm looking for tools to clean my point clouds and help me start to become a little more familiar with the tech. any help is appeciated.

Hi all, very new to LiDAR I'm wanting to do some 3d mapping of some caves and underground workings. All the units I have found online are like $20,000 plus Is there a way to build a unit to do some underground mapping? Thanks

As part of a study project, I am planning to explore and map a previously undocumented cave system. The whole thing is partly man-made and partly natural. My idea is to use LiDAR technology, as I have basic experience with the sensor in my iPhone and it has performed best in comparisons.

My problem: What is the best way to implement this? Almost everywhere in the cave is completely dark, with light only coming in at the entrances and otherwise from my flashlight. Pictures do not have to be taken, but a complete 3D plan must be produced at the end, which also contains all the dimensions.

What is the best way to do this, what can I do with my limited financial resources? As I'm still studying and don't earn much money in my part-time job, I don't have much leeway.

Thank you for any ideas!

I'm having issue with calculating xyz coordinates of the lidar data which is tilted two ways. The lidar has opening angle 60° (from -30° to 30°) and is having 300 distance measurements. Angle difference between each datapoint is 0.2°. Output of the sensor is the distance value for each point,

With perfectly aligned sensor the calculation is straightforward but on my case the sensor is tilted around two rotation axis. That makes that the projection of the beam not be vertical anymore on vertical surface. I cannot find the way to calculate right coordinates. Especially I cannot figure out what is the relation between two tilting angles and the vertical angle of the beam projection (see images below)

https://preview.redd.it/d50fif6o84sd1.png?width=406&format=png&auto=webp&s=570d5c234fdc87d8e103bfd4a41c128f6d0e0187

Tilting angle 1 (between blue and green lines) e.g 30°

Tilting angle 2 e.g. 25°

Hopefully someone gets my issue and could explain the math behind it?

We’re using a Matrice 350 RTK & L2 to survey some powerlines, and using TBC to extract the line work.

The client has come back to me and asked that include trees along the survey route - i.e. tree heigh, spread and trunk. TBC can extract trees and label their attributes.

What settings of overlap, camera angle etc should I be applying to the flight plan to best capture trees?
