Abstract

The invention relates to a light diffuser which comprises a micro-lens array formed by splicing a plurality of micro-lenses with random positions, the curved surface of each micro-lens is random, andthe curved surface of each micro-lens randomly comprises a random curved surface center position, a random curved surface Z-axis height, a random curved surface size and a random curved surface self-rotation angle. The light spot of the light diffuser is free of stripes, and the 3D imaging precision can be improved.

Description

technical field [0001] The invention belongs to the technical field of artificial intelligence three-dimensional imaging, and in particular relates to a light diffuser. Background technique [0002] At present, in the fields of 3D imaging such as 3D sensing, face recognition, machine vision, and automatic driving, there are mainly binocular, structured light and TOF technologies to realize 3D imaging. Due to its high enough precision and low cost, TOF has gradually become the mainstream of 3D imaging. The microlens units of the existing TOF light diffuser are the same and their positions are arranged periodically or randomly, so there are problems such as stripes in the illumination spot and complex imaging algorithm. Contents of the invention [0003] The purpose of the present invention is to solve the above problems and provide a light diffuser which solves the problem of streaks in the light spots. [0004] In order to achieve the above object, the present invention ...
