Yolov3跑的目标实时检测出来的图像有点泛红

VIM3
1

我用yolov3跑的目标实时检测，效果跑出来了，只是图像有点泛红，是怎么回事

2

@xingye666 用了我们的mipi摄像头么？

3

是的，用的mipi摄像头，就是跑的文档里面的yolov3的demo

4

@xingye666 我这边会进行确认，结果反馈在这

5

@xingye666 这边x11下面的demo没有ir-cut的开关选项，你可以在framebuffer下使用fb的demo，有-i on或者-i off参数开关ir-cut

6

我刚试了fb的demo，开始有画面，一动就花屏，framebuffer是另外一个系统吗

7

我跑x11的demo，用手势测试发现延时也挺厉害的

8

@xingye666 泛红的问题还会么，加上参数。花屏的问题，我们会确认

9

1、您能把那个命令写一下吗，我是直接跑了和X11平级的demo
2、fb模式怎么切换到x11模式，或者说怎么退出fb模式，
3、framebuffer下v4l2_test文件在哪儿

@xingye666

https://docs.khadas.com/zh-cn/vim3/HowToUseMIPICamera.html#测试IR-Cut

文档里面有

ctrl + Alt + F7

11

您说的是python和c++的源码吗。。。。。。

12

我直接敲命令，提示说找不到v412——test这个文件。。。

@xingye666 我们固件预装了这个命令的
