2013-03-14 02:28:35 -0500 commented answer how do i save QImage in cv::Mat

I know. I need it as CV_8UC3 in BGR format. will try cv::mixChannels later, oi maybe someone has a better idea and i don't need to search google :)

This is what i'm using now: cv::Mat image = cv::Mat(img.height(), img.width(), CV_8UC4, img.scanLine(0), img.bytesPerLine());

img is a QImage.

I'm using QTcpSocket to receive pictures from a tablet. readAll() gives me a ByteArray. Then i use LoadFromData() for a Pixmap, to display the image in a GUI.

Now i want to change it and save to cv::Mat, to be able to use imageprocessing.

Will see if your char pointer idea solves it.

operations for each pixel will be too slow. was hoping for something fast. maybe scanLine() or data() of the QByteArray class

can anyone tell me how to save QImage in a cv::Mat variable? QByteArray to cv::Mat would also work.

can anyone tell me how the coordinate system of posit is defined? i know it calculates the rotation and translation of an object in relation to the camera, but what excactly does that mean. for example if i get a rotation of 90° around the z axis. in which direction is z pointing and is the object rotating around z or the camera?
