Abstract: Described are systems and methods for generating high dynamic range (“HDR”) images based on image data obtained from different image sensors for use in detecting events and monitoring inventory within a materials handling facility. The different image sensors may be aligned and calibrated and the image data from the sensors may be generated at approximately the same time but at different exposures. The image data may then be preprocessed, matched, aligned, and blended to produce an HDR image that does not include overexposed regions or underexposed regions.

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.
