刚刷好系统的 NX 开发板,自带的 OpenCV 会处于 “Compiled CUDA : NO”的状态,这种状态下 OpenCV 只会调用 CPU 的资源,不会调用 GPU 。我们要重新安装 OpenCV。 零、NX 开发板系统介绍 NVIDIA Jetson Xavier NX with Jetpack 4.6.1 本次重装 OpenCV 的开发板是插 SD 卡的版本,因此对硬盘空间要求不严格。
-D WITH_CUBLAS=ON \ -D ENABLE_FAST_MATH=OFF \ -D CUDA_FAST_MATH=ON \ -D OPENCV_DNN_CUDA=ON \ -D ENABLE_NEON=ON \ -D WITH_QT=OFF \ -D WITH_OPENMP=ON \ -D WITH_OPENGL=ON \ -D BUILD_TIFF=ON \ -D WITH_FFMPEG=ON \ -D WITH_GSTREAMER=ON \ # -D WITH_TBB=ON \ # ...
Following up myPython compilation guide for DRIVE PX2, I wanted to utilise OpenCV 4.5+ with CUDA integration. This was only possible with compiling from scratch(No cross compilation => Directly on PX2)and here is a quick command list of how I did it. Note: Many dependencies requir...
By upgrading/installing newer OpenCV I’ve destroyed my OpenCV installation many times and i’ve had to re-flash my hardware several times. If you can live with OpenCV3.3 i would recommend you just flash using the new Jetpack 4.2 it will include Cuda 10 and OpenCV 3.3.0 for you. Thanks ...
使用jetpack安装的jetson,自带了opencv,但是没有cuda加速的,输入opencv_version查看。 使用jtop查看,可以确认自带的opencv是没用cuda的。 卸载opencv pip3 uninstall opencv-python sudo apt purge libopencv* sudo apt autoremove sudo apt update 二、安装OpenCV with CUDA的依赖 ...
1.3 安装 CUDA 下载地址https://developer.nvidia.com/cuda-downloads 注意,按照图中指令sudo sh cuda...执行之后,需要等待一段时间(并不是电脑卡了...),之后在弹出的选择中敲accept,之后选择安装选项,可以取消掉samples和documents选项。 如果安装不成功,则重新执行sudo sh cuda...,然后把第一个driver选项也取...
把with cuda取消掉吧，因为在opencv官网上下载的3.0版本是没有相关cuda库提供的，cmake当然就无法找到，所以就报错，所以不能勾选。
A small script to build OpenCV 4.1.0 on a barebones system. The script installs build dependencies, clones a requested version of OpenCV, builds it from source, tests it, and installs it.
重新指向你安装的opencv，但是我修改完没变化。原因 安装ROS时，老版cv_bridge默认连接了4.0+版本的...
解决方法: 1. 根据上述链接下载安装 NVIDIA VIDEO CODEC SDK 并安装。(未测试) 或 2. 关闭 CMake 配置中的 BUILD_opencv_cudacodec 标签。 因为用不到这个功能所以我选择不安装 opencv_cudacodec 模块,关闭后我重新编译成功通过。
