获取源码 ​

  1. 代码仓库

编译过程 ​

  1. 编译脚本
  • 默认参数且不带contrib模块
sh
#!/bin/bash
set -e

# 获取绝对路径
ROOT_PWD=$( cd "$( dirname $0 )" && cd -P "$( dirname "$SOURCE" )" && pwd )

# 创建build目录
BUILD_DIR=${ROOT_PWD}/build/build_linux_aarch64
if [[ ! -d "${BUILD_DIR}" ]]; then
  mkdir -p ${BUILD_DIR}
fi

cd ${BUILD_DIR}
cmake -B . -S ${ROOT_PWD} \
-DCMAKE_INSTALL_PREFIX=/opt/opencv \
-DCMAKE_BUILD_TYPE=Release \
-DCMAKE_C_COMPILER=/usr/bin/aarch64-linux-gnu-gcc \
-DCMAKE_CXX_COMPILER=/usr/bin/aarch64-linux-gnu-g++ \
-DCMAKE_SYSTEM_NAME=Linux \
-DCMAKE_SYSTEM_PROCESSOR=aarch64

make -j8
  • 带opencv_contrib的情况
bash
# 拉取opencv_contrib源码
> cd <opencv_path>
> git clone https://github.com/opencv/opencv_contrib.git


# 根据实际情况修改编译脚本
# 启用opencv_contrib模块
-DOPENCV_EXTRA_MODULES_PATH=${ROOT_PWD}/opencv_contrib/modules

# 启用nonefree模块
-DOPENCV_ENABLE_NONFREE=ON
  1. 执行编译
bash
> chmod +x build.sh
> ./build.sh

> cd ./build/build_linux_aarch64
# 部分路径需要sudo权限
> make install
