Abstract
An optical safety scanner system comprises a first illumination source for detecting presence and distances of people or other objects within a hazardous industrial area based on triangulation, and a second illumination source that verifies accurate and reliable detection by the first illumination source. The first illumination source can project LED or laser light for triangulation of objects, and the second illumination source can project a wide beam of light for detection of other intrusive objects that may be blocking the scanner system's camera and preventing accurate triangulation of people or vehicles. If the image frame generated based on the second light identifies presence of an object that is not detected by the triangulation analysis of the laser light, the safety scanner system assumes that an object is obstructing the safety scanner system's camera, and performs a suitable safety action.
