1. An optical safety system, comprising: a memory that stores computer-executable components; a processor, operatively coupled to the memory, that executes the computer-executable components, the computer-executable components comprising: a pixel array component configured to, for one or more pixel arrays of one or more images of a hazardous industrial area captured by one or more imaging sensor devices, group pixels of the one or more pixel arrays to yield a subset of the pixels on which two-dimensional (2D) analysis is to be performed; an image analysis component configured to perform 2D analysis on the subset of the pixels; a distance determination component configured to perform 3D analysis on point cloud data received from the one or more imaging sensor devices; and a hazard analysis and decision component configured to classify a first object in the one or more images as motorized industrial equipment and a second object in the one or more images as a human based on results of the 2D analysis and the 3D analysis, to correlate the results of the 2D analysis and the 3D analysis to yield correlated information relating to a relationship between the human and the motorized industrial equipment, and to generate a control output that controls the motorized industrial equipment based on the correlated information.
