Bug in projection

Open mrtpk opened this issue 6 years ago • 4 comments

While I was analyzing the output of the code by taking a bird's eye view, I saw that it doesn't match the expected output. When I did projection separately in a jupyter notebook and used the logic of generating labels given in main.py, I got the expected output. So my best guess is that there is some problem with projection in thirdparty/calib.py. I tried to debug the problem but availed no success. I have attached a sample input and output for reference.

Expected output: required_ouput

PCP output: pcp_output

A sample input for running pcp is attached. sample_input.zip

HI @mrtpk , could you share your code for the first method? My guess is that the calib code is not thresholding the values according to z>0, (and maybe some other mistakes as well). Thanks Gunshi

Hi @gunshi, It has been a long time since I have open this issue- Let me try to get the code and get back to you. Thanks, Thomas.

Hi @gunshi, I apologize for the late reply. I have tried to debug this issue and could not find a solution. The code for the first method can be found in get_annotation at https://github.com/mrtpk/lidar-buster/blob/master/tutorial/LiDAR%20annotation%20for%20KITTI%20road%20dataset.ipynb

All the best, Thomas.
