Jetson TX2上的demo
一、快速傅里叶-海动图 sample
The CUDA samples directory is copied to the home directory on the device by JetPack. The built binaries are in the following directory:
/home/ubuntu/NVIDIA_CUDA-<version>_Samples/bin/armv7l/linux/release/gnueabihf/
这里的version需要看你自己安装的CUDA版本而定
Run the samples at the command line or by double-clicking on them in the file browser. For example, when you run the oceanFFT sample, the following screen is displayed.
二、车辆识别加框sample
