上面是我的代码,告诉不同的颜色,但事实证明主要功能有问题。基本上主要功能就是激活凸轮。错误是:“GetThresholdedImage不接受1个参数”。有人可以给我一些提示吗?
答案 0 :(得分:1)
该行
IplImage* imgThresh = GetThresholdedImage(imgHSV);
是导致错误的原因。功能界面
GetThresholdedImage
有三个参数,如
中所用IplImage* blue_mask = GetThresholdedImage(hsv, blue_lower, blue_upper);
IplImage* green_mask = GetThresholdedImage(hsv, green_lower, green_upper);
您必须添加其他两个参数,例如:
IplImage* imgThresh = GetThresholdedImage(imgHSV, blue_lower, blue_upper);
取决于您对图像的处理方式。
