OpenMV感兴趣区域(ROI)是图像分析中关注的重点区域。通过设置ROI,可以减少处理时间,提高处理精度,并为图像处理提供便利。在OpenMV中,设置ROI区域可以减少计算资源的消耗,从而提高系统的运行速率。通常,ROI区域是一个矩形,通过指定左上角的坐标和宽度、高度来定义。在OpenMV中,可以设置多个ROI区域,并为每个区域分配权重值。离视野越近的区域,权重值应该更大。例如,可以设置三个ROI区域,每个区域的大小为120x30像素,并分配权重值为0.7、0.3和0.1。通过设置ROI区域,可以在OpenMV中实现循迹功能,并获取ROI区域内的图像统计信息,如LAB通道的模式值。\[1\]\[2\]\[3\]
