Convert from RGBP or BAYER to BGR?

0 votes

How would one convert RGBP or BAYER to openCV BGR in C++?

I'm aware of functions such as jevois::rawimage::convertToCvBGR(), and jevois::rawimage::convertCvBGRtoRawImage() for converting YUYV to BGR, but it doesn't seem to work for RGBP or BAYER. When I attempt it, I get "Caught std::exception [FTL RawImage::require: Incorrect format for RawImage input: want 640x480 YUYV but image is 640x480 RGGB"

convertToCvBGR() should work with any of the pixel formats supported by our sensor, including RGBP and BAYER.

Your error is coming from require() which is probably in your top-level module code, just before you do the conversion. require() is used to enforce that the camera (or USB output) format has some specific specs so that the module code does not have to be too complex. For example, often we only support YUYV so that we can use the drawing functions that only work with YUYV.

Indeed, have a look at the image format conversion module at http://jevois.org/doc/ModuleTutorial.html

That one works with all possible camera pixel types. It has no require() call on the inimg. See require() here for more info: http://jevois.org/doc/RawImage_8H_source.html
