DIMENSIONAL CALIBRATION OF THE FIELD-OF-VIEW OF A SINGLE CAMERA

摘要

A method for calibrating an active FOV of a single camera, wherein from the calibration of the camera's active FOV, a coordinate matrix is obtained which remotely produces a virtual interpolation measurement network at any point within an image (a frame) extracted from a video stream (recorded by the single camera), while eliminating the need to be physically located at the actual location where the video stream has been recorded. According to an embodiment of the invention, the basis of the active FOV of a camera is the ability to obtain (measure) coordinates of the measurement points marked on a calibration board.
