注意注释部分,其中使用的比较生疏的 API 包括cvPyrDown,cvCreateCameraCapture 以及cvCopy和cvSaveImage 下面就来一一解释这几个 API 的具体使用: void cvPyrDown( const CvArr* src, CvArr* dst, int filter=CV_GAUSSIAN_5x5 ); 其中src 为 CvArr * 类型,这里顺便解释一下 OpenCV 基本上是用 C 实现的,当...
获取一张图像并对其进行去畸变。使用cv.getOptimalNewCameraMatrix(),其需要输入一个缩放参数,如果缩放参数alpha=0,它返回最小不需要的像素的去畸变图像。因此,它甚至可能会删除图像角落的一些像素。如果alpha=1,所有像素都被保留,但会有一些额外的黑色图像。这个函数还返回一个图像ROI,可以用来裁剪结果。 img = cv...
def distance_to_camera(knownWidth, focalLength, perWidth):# compute and return the distance from the maker to the camerareturn (knownWidth * focalLength) / perWidth distance_to_camera 函数传入目标的实际宽度,计算得到的焦距和图片上目标的像素宽度,就可以通过相似三...

cameraImg.data中存有图像数据,data的大小可以根据图像的高度、每行图像的步幅计算出来。c#调用此函数后,imgBuffer存放图像数据。对数据imgBuffer处理后,就可以在控件上显示。 c语言对opencv封装函数列表如下: extern"C"{ OpenCVCamera_APIintCamera_GetCameraName(char*listName); ...

In my C/C++ program, I'm using OpenCV to capture images from my webcam. The camera (Logitech QuickCam IM) can capture at resolutions 320x240, 640x480 and 1280x960. But, for some strange reason, OpenCV gives me images of resolution 320x240 only. Calls to change the resolution using ...
