Opencv distance. We take a picture of our object using our camera and then Jul 23, 2025 · The OpenCV distanceTransform () function is an image processing function that calculates the Euclidean distance between each non-zero pixel in an image and the nearest zero pixel. . Open Source Computer Vision Library. You can apply distance transform in OpenCV using the method distanceTransform (). In order to determine the distance from our camera to a known object or marker, we are going to utilize triangle similarity. This function takes the binary image, distance type, and mask size as arguments. By using it, one can process images and videos to identify objects, faces, or even the handwriting of a human. Mar 2, 2026 · The inter-marker distance is the minimum Hamming distance between dictionary markers that determines the dictionary's ability to detect and correct errors. 使用 OpenCV 函数 cv::filter2D 进行拉普拉斯滤波以锐化图像 使用 OpenCV 函数 cv::distanceTransform 获取二进制图像的距离变换表示形式，其中每个像素的值被替换为其到最近背景像素的距离 使用 OpenCV 函数 cv::watershed 将图像中的对象从背景中分离出来 理论 代码 Dec 26, 2012 · 1 there is no such function available in opencv to calculate the distance between object and the camera.
