上面是我告诉不同颜色的代码，但事实证明 main 函数有问题。 基本上，主要功能只是激活凸轮。 错误是："GetThresholdedImage 不接受 1 个参数"。 有人可以给我一些提示吗？

行

IplImage* imgThresh = GetThresholdedImage(imgHSV);

是导致错误的原因。函数的接口 

GetThresholdedImage

有三个参数，如 

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);

取决于您要对图像执行的操作。
