I am a newbie to OpenCV and C++. Recently I have executed some coding, the code successfully run, however, there are also some errors involved in the .exe window Here is the image showing the errors i have mentioned above Error while coding Since I am new to this field, I don’t know how to ..
I am working with openCV arUco markers to detect some markers. So I generated pre-defined dictionary and saved it in a file. However the aruco::detectMarkers can only get Ptr<aruco::Dictionary>. So I create a Ptr<aruco::Dictionary> object and sent to the constructor the address of the object itself. This is causing to exception at the end of ..
I want to know the real position and orientation of my marker. If I understood well, tvecs gives me the real position of my marker, I measure the distance with a ruler and it seems be correct even I had sometimes weird values. If someone has an idea of why ? Unfortunately, rvecs gives me ..
I am trying to detect AruCo markers from image data sent from Unity to OpenCV c++ dll. Versions OpenCV:4.5.0/4.5.1 Unity : 2020.1.17f1 Aruco dictionary : 6x6_250 family and AprilTags 36h11 family The problems I am facing is: i) when I use a camera and send each frame(as shown in code here), detectMarkers() function works but ..
I work on a project with aruco markers with OpenCV and I want to compare some parameters : I’m going to enter the distance between the marker and camera for example 30cm/0.03m, the size of the marker and the orientation. Then I’m going to do the marker detection and the pose estimation : I can ..
I am using OpenCV’s aruco::CharucoBoard object for calibration purposes and noticed that its marker detection doesn’t find all visible markers/corners in the images. I started investigate the matter and tried to detect the markers on the image of the board that was printed for the calibration. The aruco::detectMarkers fails to detect all markers unless the ..
ARUCOMARKER DETECTION is my project title I need a help in Arucomarker detection. Using C++ code . My code is not detect the arucomarker. My background is to apply C++ code for its detection but it doesn’t work. Source: Windows Que..
First time posting here, tell me if you need something else in order to help me! I am trying to set up a simple AR application using ArUco and OpenGL in C++. I build and installed ArUco, same for freeglut because glut is quite old by now but after solving a certain number of issues, ..
I do not understand the creation of the chees board aruco this is the method: static Ptr<CharucoBoard> cv::aruco::CharucoBoard::create ( int squaresX, int squaresY, float squareLength, float markerLength, const Ptr< Dictionary > & dictionary ) Number of chessboard squares in X direction. Number of chessboard squares in Y direction. Length of square side. Length of marker ..
