opencv_createsamples:在 ubuntu 中找不到命令 [英] opencv_createsamples: command not found ubuntu

问题描述

我正在关注 创建您自己的 Haar Cascade OpenCV Python 教程 但是当我开始制作样本时，我得到 opencv_createsamples: command not found

I am following Creating your own Haar Cascade OpenCV Python Tutorial But when I get to making the samples I get opencv_createsamples: command not found

我正在使用它来创建示例 opencv_createsample -img img.jpg -bg bg.txt -info info/info.lst -pngoutput info -maxxangle 0.5 -maxyangle 0.5 -maxzangle 0.5 -num 573

I am using this to create the samples opencv_createsample -img img.jpg -bg bg.txt -info info/info.lst -pngoutput info -maxxangle 0.5 -maxyangle 0.5 -maxzangle 0.5 -num 573

但我知道该命令存在，因为当我执行 man opencv_createsamples 时，它会打开手册页.我使用的是 ubuntu 20.04.1

but I know the command exists because when I do man opencv_createsamples it pulls up the man page. I am using ubuntu 20.04.1

推荐答案

我在尝试获得 Haar Cascade 时也遇到了同样的问题.​​此处也提到了类似的问题.

I have also met this same problem while trying to get Haar Cascade. Similar problem also mentioned here.

根据@Alekhin 所说这里:

According to @Alekhin saying here:

为了能够使用 opencv_createsamples 命令，你应该使用opencv 3.x 或更低版本.

To be able to use opencv_createsamples command, you should use opencv version 3.x or lower.

此步骤(创建样本)仅用于获取我们的样本.所以我的建议:

This step(creating samples) is only necessary to get our samples. So my suggestions:

1. 在 docker 中安装支持的 opencv 版本并获取示例

1. Installing supported opencv version in a docker and getting samples

在另一台机器上安装支持的 opencv 并获取示例

Installing supported opencv in another machine and getting samples

注意:我不建议你安装opencv，而你的机器上已经有其他的了.

Note: I don't suggest you to install opencv while other one already exist in your machine.

同样的问题也提到了这里和这里.

Same problems also mentioned here and here.

用于在 docker 上安装 opencv.
