WebbDescription. convert_image_type converts images of an arbitrary type into an arbitrary new image type. If the conversion is done from a larger to a smaller gray value range (e.g., from 'int4' to 'byte'), too large or too small values are simply “clipped”. If the result images are of type 'direction', gray values that are not in the value ... Webb31 mars 2024 · 2024-03-31 09:37:10 OpenCV的Mat和Halcon的HObject类型互相转换

Webb9 apr. 2024 · 但是发现和预期的不一样因为Img里面的值在return前同样被改变了一次,是因为我们用的浅拷贝里面的值还是对应的mat所以在mat转化回去后Image里面的值又变回去了。转后后会影响到外面的mat值,然后我再次传入后mat的值已经是转化后的了。所以这个问题解决的方案是再return QImge的时候再一次转化回去。 WebbQImage/cv::Mat互相转换QImageImgChange::cvMat2QImage(constMat&mat)//Mat改成QImage{if(mat.type()==CV_8UC1)//单通道{QImageimage(mat.cols,mat.rows,QImage::Format ...
