Four types of detection(traffic)

Four types of detection are the case demonstrations that come with DeepStream: detecting and counting people, cars, road signs, and bicycles in the picture.

The tutorial only provides basic demonstrations, and other applications need to be developed by users

1. Video detection

Enter the folder where the case is located:

xxxxxxxxxx
cd /opt/nvidia/deepstream/deepstream-7.1/sources/apps/sample_apps/deepstream-test1

Compile source code: refer to README in the same folder

xxxxxxxxxx
sudo make CUDA_VER=12.6 # Factory image compiled, no user compilation required

Run the case: refer to dstest1_config.yml in the same folder

xxxxxxxxxx
./deepstream-test1-app dstest1_config.yml
or
./deepstream-test1-app ../../../../samples/streams/sample_720p.h264

Configuration Files：dstest1_config.yml

2. Real-time detection

If there are multiple cameras, modify the .txt configuration file yourself: The following cases are the results when the motherboard is connected to only one camera.

2.1. USB camera

xxxxxxxxxx
cd /opt/nvidia/deepstream/deepstream-7.1/samples/configs/deepstream-app

xxxxxxxxxx
deepstream-app -c source1_usb_dec_infer_resnet_int8.txt

2.2 CSI Camera

xxxxxxxxxx
cd /opt/nvidia/deepstream/deepstream-7.1/samples/configs/deepstream-app

xxxxxxxxxx
deepstream-app -c source1_csi_dec_infer_resnet_int8.txt
