大家好： 有谁遇到这种情况或类似情况，大恒工业相机 MER2-301-12GU3M-5-637，在相机配置时，点击测试如下报错，

我没有使用 OpenPnP，但我认为这是因为 OpenPnPCapture 对此存在兼容性问题——它只支持 UVC 摄像头

Daheng camera used to support python or c++ drivers to start capature ... To use a UVC camera, you might need to write a drivers allows uvc to call python or c++ drivers and transfer back to uvc.

you could also use the opencv camera driver - it should work

or you compile openpnp-capture with the correct FourCC

Okay, i think the pictures should be showing up now

just for fun i checked whats wrong with openpnp-capture - there are some twisted numbers

(maybe Jason could correct it in next update)


it should be:      format4cc = ' RGB';

it should be:      return MAKEFOURCC('B','G','R',' ');

it should be:      newFrameInfo.fourcc = MAKEFOURCC('B','G','R',' ');

After compiling openpnp-capture and building openpnp-capture-java and swapping the jar file most low cost "industrial" cameras (mindvision, daheng, etc.) should work in windows with OpenpnpCaptureCamera driver even though you have to set all the parameters - such as resolution, exposure time, gamma, etc. - in advance using the manufacturer's software.

Sorry, i sent you three private emails in response to your enquiry, but it seems none of them got through.

You can try this driver with above changes. It works on my Huateng and Mindvision cameras.
It is important that you adjust everything (resolution, exposure, etc.) with the manufacturer software and store it in the camera before you start OpenPnP.

As your camera has a very powerful sensor (IMX252), I would recommend reducing the resolution (e.g. 1024x1024 pixels or smaller) to speed up image processing.

您好

     非常感谢你的帮助，覆盖后，完全可以使用，虽然帧率低了些，不然我就要放弃这个相机了，太酷了。

再次感谢您的帮助

若是网络接口是不是还要其他设置，才能使用相机？
