02 | python调用处理工业相机

1 背景

设备:海康威视的相机

2 实操

2.1 底层接口

在这里插入图片描述

具体路径是:C:\Program Files (x86)\MVS\Development\Samples
在这里插入图片描述
用以方便二次开发中对接口的调用;python语言的接口可以参考C版本;

2.2 常用接口

python中支持的接口以及参数可以从相应文件中查取,参考路径:C:\Program Files (x86)\MVS\Development\Samples\Python\MvImport
在这里插入图片描述
其中最主要调用的是 MvCameraControl_class.py ,该文件中包含从C语言底层接口封装过来的所有 python 可调用接口,在调用时是需要导入该文件作为调用包;文章来源地址:https://www.uudwc.com/A/9dBXV/

    • UpcomingImage: 在调用取流接口时忽略输出缓存列表中所有图像,并等待设备即将生成的一帧图像。该策略只支持GigE设备,不支持U3V设备
