Hi, @kalai86!
You need a lidar that produces *.pcd files. Your modifications may start at line 115 in the
It depends on your goals. If you want to analyze lidar point cloud on a laptop, then there are no strict hardware requirements, except that this laptop should be relatively modern. If you want to utilize this code in a robot, such as a self-driving car, then you need to thoroughly analyze the hardware available to you and adjust the code. I think, in this case, the adjustments may be quite significant.

hi Sergey, thanks for your reply. CMakeFiles/lidar_obstacle_detection.dir/build.make:62: recipe for target 'CMakeFiles/lidar_obstacle_detection.dir/src/main.cpp.o' failed i have attached error message text file also . thanks |
@kalai86, you are using

hi Sergey, thanks for your reply. please suggest me thanks |
Hi, @kalai86! I did not work directly with the PCAP files yet, but it seems that PCL is capable of working with them as well: http://www.pointclouds.org/documentation/tutorials/hdl_grabber.php. I have also found some ROS documentation pages with the instructions on how to convert PCAP files to PCD files as well as a PCL forum post suggesting a possible solution: |
Hi Sergey, thanks for reply. thanks |
What is the format of your data? PCAP? I do not think that the code would work with PCAP data without modifications. I have never worked with the PCAP format, so I cannot comment on the topic of processing PCAP data except pointing you to some documentation pages I have found on the Internet. Although, I would be interested in adopting this code for processing several kinds in Lidar data formats. I would look into how to make it work if you share your data with me.
Changes should go to https://github.com/ser94mor/lidar-obstacle-detection/blob/master/src/PointCloudProcessor.hpp#L379. |
Hi Sergey, i have share the link of PCAP file. https://data.kitware.com/#collection/5b7f46f98d777f06857cb206/folder/5b7fff608d777f06857cb539 thanks |
Hi Sergey,
if you have please suggest me thanks |
Hi, @kalai86, Thank you for sharing the data. I would be very interested in looking into it. I would look into your data and the problem of PCAP to PCD conversion as soon as I have time. I think it would be a Monday evening (2019-07-15). Thanks, |
Hi Sergey, Thank you . i am waiting for your reply.. thanks |
Hi sergey, i am also trying to give the proper data from another code ( https://gist.github.com/UnaNancyOwen/9f9459d3c10f7a6325ebebabda9865f7) but i cant give it properly.so please suggest me Thanks |
@kalai86, I am looking into it now. |
Ok.thanks
If u complete pls share me

hi,
how to execute PCAP file or directly from sensor data. thanks |
hi, i have converted sensor data into pcd format.these input file given to your code but its detect some wrong detection .i share link of input pcd file and output video file.so please refer my data and suggest me i hared same data to your mail also thanks |
Thanks for providing data. I think the problem is in the parameter values. You need to tune some parameters here: https://github.com/ser94mor/lidar-obstacle-detection/blob/master/src/main.cpp#L46. I will look into your data and get back to you. Thanks, |
You need to use PCL library implementations of corresponding algorithms to get better results. See the attached GIF. Notice the command I use to run the program: Sergey |
hi sergy, thanks,but i got some error when excuting this command. ./lidar_obstacle_detection ../data/pcd/data_3/ true thanks |
hi sergey, how to give the direct cloud point into your code without pcd file format. thanks |
hi
i saw your code .i try to execute the code , how to get the data from real time sensor ,what to do the change in code and where it is?
hardware requirements?
software requirements?
please suggest me
thanks
