how's the performance on 16 beams lidar data?

[lucasjinreal]

Does there any performance demonstration videos or gif to show detection result on 16 beams data?

[muzi2045]

[lucasjinreal]

@muzi2045 Seems a little slow..

[muzi2045]

record problem, inference_time between 30ms~50ms

[lucasjinreal]

Then why get this blocked effect?

@muzi2045 how to prepare 16-beam lidar?make it kitti like format?

[wyjforwjy]

do you still use the pre_train model for the 16 beam lidar?@muzi2045 @muzi2045

[muzi2045]

No, that's not pertained model released by Author

[wyjforwjy]

Thanks!!

You pretrain the model by KITTI?or by nuscenes @muzi2045

[muzi2045]

both dataset are trained, nuscenes performs better.

thank you very much!

@muzi2045 Hi Muzi，for pretraing your 16 beam model with kitti and nuscene, did you use the original 64/32 beam data , or downsample them to 16 beam?

Thank you in advance!

[muzi2045]

trained with 64/32 beam lidar data, inference with 16 beam lidar data, don't need to downsample @turboxin

[turboxin]

@muzi2045 thank you very much!

[turboxin]

@muzi2045 hello！You mentioned that inference_time is between 30ms~50ms, may I ask what GPU are you using? Could you please also provide some quantitative performance data on your results on 16 beam lidar? Thanks a lot!

[muzi2045]

if you using 1050Ti , inference time between 40ms ~ 60ms (without tensorrt speed up) with 1080TI , inference time between 15ms~30ms(without tensorrt)

[mmxiami]

trained with 64/32 beam lidar data, inference with 16 beam lidar data, don't need to downsample @turboxin

how to run the demo on my own dataset?(32 beams data),could you help me?Thank you in advance!

@muzi2045 Hi, could u share ur pretrained model. I have trained Kiiti dataset and inference on velodyne 16, but the result seems not good. very appreciate

[dhellfeld]

@muzi2045 Hi, could you show an example of how you converted the model to tensorrt?

[muzi2045]

there has some problem in pytorch-> onnx -> tensorRT, I can't successfully convert this model in tensorrt to speed up the inference cost time. But you can refer this repo, the author looks like convert success. nutonomy_pointpillars Good Luck to you @dhellfeld

@muzi2045 Hi, Thanks for your share, I am a newer in this area, could you give some advice on how to use SECOND do the inference and visualization work as the GIF you shown.
