The Aim and Principle of Depth of Field Calibration
According to 1 plane line and 3 height lines calibrated by the user and the
corresponding distances in the actual environment, the system estimates the
internal parameters (including internal geometric characteristics and optical
characteristics) and external parameters (the 3D position and direction of the
camera relative to the actual environment coordinate system) of the Device, and
then determines the corresponding relation between the 2D image acquired by the
camera and the real 3D object.
Configuration and Requirements of Depth of Field Calibration
•
Scene requirements
Medium or far view with the camera installation height of more than 3 meters. Not
suitable for scenes with parallel view or ceiling mount.
Only calibrate on horizontal plane, not on vertical wall or inclined plane.
Not applicable to scenes with distorted images, such as scenes with ultra-wide angle
cameras and fish-eye cameras.
