  • Camera installation assistance device and method, and installation angle calculation method, and program and recording medium
    Patent number: 11259013
    Abstract: In a state in which an optical axis of a camera is normal to a surface, a relative angle of a projector with respect to the camera is set such that a marker is formed at the intersection of the optical axis of the camera with the surface. In a state in which the relative angle is unchanged and an installation angle of the camera is changed, the marker formed on the surface is shot by means of the camera, and, based on a distance between the marker and the intersection in the image obtained by the shooting, the installation angle of the camera is calculated. Furthermore, an error of the calculated installation angle with respect to a target value is calculated and displayed. Calculation or adjustment of the installation angle can be made even if the surface on which the marker is formed is relatively narrow.
