Models

1. Convert CenterNet model to onnx. See here for details.
2. Use netron to observe whether the output of the converted onnx model is (hm, reg, wh)

Example

cd TensorRT-CenterNet
mkdir build
cd build && cmake .. && make
cd ..

##ctdet | config include/ctdetConfig.h 
## float32
./buildEngine -i model/ctdet_coco_dla_2x.onnx -o model/ctdet_coco_dla_2x.engine 
./runDet -e model/ctdet_coco_dla_2x.engine -i test.jpg -c test.h264

##cthelmet   | config include/ctdetConfig.h
## flaot32
./buildEngine -i model/ctdet_helmet.onnx -o model/ctdet_helmet.engine -m 0
./runDet -e model/ctdet_helmet.engine -i test.jpg -c test.h264
## int8
./buildEngine -i model/ctdet_helmet.onnx -o model/ctdet_helmet.engine -m 2 -c calib_img_list.txt
./runDet -e model/ctdet_helmet.engine -i test.jpg -c test.h264

## run eval_coco.py | conifg your cocodaset and ctdet_coco engine 
python3 eval_coco.py model/ctdet_coco_dla_2x.engine
