cv::aruco::drawDetectedMarkers(image, markerCorners, markerIds); Marker Detection 给定一个可以看见 ArUco marker 的图像,检测程序应当返回检测到的 marker 的列表。每个检测到的 marker 包括: 图像四个角的位置(按照原始的顺序) marker 的 Id marker 检测过程由以下两个主要步骤构成: 检测有哪些 marker。在这...
Python: corners, ids, rejectedImgPoints = cv.aruco.detectMarkers( image, dictionary[, corners[, ids[, parameters[, rejectedImgPoints[, cameraMatrix[, distCoeff]]] ) #include <opencv2/aruco.hpp> Basic marker detection. Parameters image input image dictionary indicates the type of markers that w...
Step #3:Perform ArUco marker detection via thecv2.aruco.detectMarkersfunction. Most important to us, we need to learn how to use thedetectMarkersfunction. Understanding the“cv2.aruco.detectMarkers”function We can define an ArUco marker detection procedure in, essentially, only 3-4 lines of co...

To estimate the translation and the rotation of the ArUco marker, run below code: cd pose_estimation mkdir build && cd build cmake ../ make ./pose_estimation -l=<side length of a single marker (in meters)> # or, if you are trying this on an already saved video ./pose_estimation ...

Python import cv2 as cv import numpy as np # Load the predefined dictionary dictionary = cv.aruco.Dictionary_get(cv.aruco.DICT_6X6_250) # Generate the marker markerImage = np.zeros((200, 200), dtype=np.uint8) markerImage = cv.aruco.drawMarker(dictionary, 33, 200, markerImage, 1); ...
Consider the inter-marker distance.OpenCV’s ArUco detection implementation utilizes error correction to improve the accuracy and robustness of marker detection. The error correction hinges on the concept ofinter-marker distance.Smaller dictionary sizes with largerNxNmarker sizes increase the inter-marker...
