From the Lidar point cloud how the lidar data is stored as a cell array of pointCloud objects.
My steps to perform automatic bounding box formation are.,
1- PCAP input to the MATLAB to see the point cloud -----> Done
2-Segment ground points from organized lidar data---------> Done as per the example given as MATLAB Examples.
3- Track Vehicles Using Lidar: From Point Cloud to Track List----> Done
4- Bounding Boxes formation of the Ground Truth Lebeling - From the example "https://in.mathworks.com/help/driving/examples/track-vehicles-using-lidar.html#responsive_offcanvas" i am not clear to below items.
% Load data if unavailable. The lidar data is stored as a cell array of % pointCloud objects
if ~exist('lidarData','var'). % -------> Here to create "lidarData" i will input the PCAP or the csv ?%
% Specify initial and final time for simulation.
initTime = 0;
finalTime = 35;
[lidarData, imageData] = loadLidarAndImageData(initTime,finalTime);
end
I would very much appreciate any help! I think that I really don't understand how the PointCloud2 messages are formatted...
