cv_calib_use_intrinsic_guess is set ). · Cv_calib_fix_aspect_ratio-only one independent variable exists in FX and FY during the optimization process, and the ratio FX/fy remains unchanged. The value of FX/fy is the same as that of the parameter matrix during initialization. In this case, the actual initial values of (FX, FY) can be read from the input Memory Matrix (when cv_calib_use_intrinsic_guess is specified ), or use the estimated value (in the latter case, FX and FY may be set to any valu

OpenCV through the Videocapture class, to read the video, call the camera Read Video: 1. Instantiate and initialize first Videocapture capture; Capture.open ("1.avi"); 2. Initialize simultaneously with instantiation Videocapture Capture ("1.avi"); Play Video: After the video reads like a Videocapture class object, use a loop to display each frame while (1) { Mat frame; capture>>frame; Imshow ("read video

I. Reading a video sequence OPENCV provides an easy-to-use framework for extracting image frames from video files and USB cameras, and if you simply want to read a video, you just need to create a cv::videocapture instance and extract each frame in the loop. Here the video is taken with the camera and saved as AVI file, the code is as follows: #include A video file named "Fcq.avi" was created in the E-dri
