1. 交叉编译。交叉编译参考链接
2. 将编译得到的头文件放在路径lyw@lyw:~/PSDK0010/ti-processor-sdk-rtos-j721e-evm-07_01_00_11/targetfs/usr/include$。已编译opencv头文件下载链接: https://pan.baidu.com/s/1EnD3WC0J8ItKHUZVnM9Nxw 密码: kppn
3. 查看~/PSDK0010/ti-processor-sdk-rtos-j721e-evm-07_01_00_11/targetfs/usr/lib下的tda4自带libopencv_*so.文件。
4. opencv 软链接。在ti-processor-sdk-rtos-j721e-evm-07_03_00_07/targetfs/usr/lib路径下，执行ln -s libopencv_core.so.4.1 libopencv_core.so，缺少其他库时也需进行软连接。
