QT下基于opencv3.2的HSV图像分离，通过查找V分量上ROI区域最亮值的坐标，找到H分量上对应坐标的3*3矩形平均H值，判断出该坐标所处位置的颜色分类(QT under the opencv3.2 based HSV image separation, by looking for the V component on the ROI region of the brightest value coordinates, find the corresponding 3*3 coordinates of the H components of the rectangular average H value, to determine the location of the coordinates of color classification)
