Webunknown object points, a camera calibration procedure takes place. The projection of a point from 3D space to the 2D camera image sensor plane is described by a camera model and the parameters of that model. Calibration is a process during which particular parameters are determined [4]. Over the course of years different methods/tools evolved WebMar 21, 2024 · A new method for automatic calibration of surveillance cameras using keypoints or landmarks automatically detected on the observed objects by a convolutional neural network is presented, resulting in internal (focal length) and external parameters and scene scale of the surveillance camera.
