测试很多找到一个可用的。

它用了超级模块 OpenCV的world模块也称为超级模块super-module它结合了用户选择的所有其它模块。在编译OpenCV库时有需要勾选BUILD_opencv_world模块其作用是将所有模块的库文件合并成一个大的库文件方便在链接时候的操作。
这样就不用自主编译了。但是已经自主编译了一个还是记录下吧。
2、自主编译
找了很多github的编译好的文件都没法用。还是自己编译吧。
opencv的交叉编译工具链在…/opencv3.4.16/platforms/linux 路径下linux文件夹下是一些.cmake文件对应不同的移植对象本人需要在NVIDIA的Xavier部署模型所以选择aarch64-gnu.toolchain.cmake 工具链。在opencv3.4.16目录下编写build.sh文件然后执行./build.sh --mlu-archSD5223C --cpu-archaarch64。 具体的buld.sh 这样写
这个脚本只有2个地方需要修改
如果你的交叉编译器的地址修改第53行 TOOLCHAIN_ROOT/tmp/aarch64--glibc--stable-2020.08-1。TARGET_C_COMPILER和TARGET_CXX_COMPILER地址需要注意。其他地方都很好理解。如果不理解请在评论区讨论。 TARGET_C_COMPILER${TOOLCHAIN_ROOT}/bin/${TARGET_CPU_ARCH}-gccTARGET_CXX_COMPILER${TOOLCHAIN_ROOT}/bin/${TARGET_CPU_ARCH}-g#!/bin/bash

popd这个脚本还是很好用的如果理解里面的知识点的话
make install编译结束后进入aarch_64_install文件夹里面生成binincludelibshare四个文件夹。 参考

检查
利用file draw_image检查可执行文件格式是否支持arrch64
draw_image: ELF 64-bit LSB shared object, ARM aarch64, version 1 (GNU/Linux), dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, for GNU/Linux 3.7.0, BuildID[sha1]42f4ae7c66a0875bc0d49e4195ff35aa08f15cbe, not stripped 出现如上结果说明可执行文件支持ARM arrch64。
移植ARM端执行
将 aarch_64_install文件夹下的include和lib里的文件分别拷贝到ARM板的/usr/include 和/usr/lib下 然后打开终端执行可执行文件即可。
