错误消息 (-215:assertion failed) _src.depth() == cv_8u in function 'canny' 表示在调用 OpenCV 的 Canny 函数时,输入的图像深度(数据类型)不符合要求。Canny 函数要求输入图像的数据类型必须是 8 位无符号整数(即 CV_8U),但提供的图像数据类型并不满足这一条件。 可能导致该错误的常见原因 图像数据类...
Canny 边缘算法需要灰度图像才能正常运行,我们可以在 OpenCV 中将 RGB 图像读取为灰度,如下所示: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 # helperfunctionto easily display our images defimg_show(title,image):plot.title(title)plot.xticks([])plot.yticks([])plot.imshow(image,cmap="gray")p...

在刚开始使用OpenCV来编写一些图像处理程序时,经常会遇到使用cvCanny方法边缘检测出现的错误:unsupported format or combination of formats() in unknown function(function cvCanny)。(编译链接时不会报错,运行会出错) cvCanny函数的定义如下: voidcvCanny(constCvArr* image, CvArr* edges,doublethreshold1,doublethre...
