Abstract

The invention provides an automatic focusing method and system for a light source projector. The method comprises the steps that S1 a light source projector projects at least one light beam to the space; S2 an acquisition module acquires the light spot image of the light beam; S3 according to the acquired light spot image, a calculation module calculates definition parameter values; and S4 a focusing module compares the parameter values acquired in real time to acquire the optimum parameter value, and adjusts a light source to the optimum position according to the optimum parameter value. According to the method and the system, automatic focusing of the light source projector is realized; the problem of poor precision caused by manual focusing in the prior art is overcome; and the focusing efficiency is greatly improved.

Description

technical field [0001] The invention relates to the fields of optical technology and computer technology, in particular to an automatic focusing method and system for a light source projector. Background technique [0002] Laser projectors are often used in optical measurement, especially the generation and wide application of depth cameras based on structured light at present, which has prompted the continuous development of laser projectors as one of its components. At present, most laser projectors use a single edge-emitting laser light source. With the continuous development of lasers, vertical cavity surface lasers will be more and more popular due to their advantages such as small divergence angle, low power consumption and cost, small size and easy integration. More and more laser projectors are used. [0003] Although the vertical cavity surface emitting laser has many advantages, it is relatively difficult to adjust the relative position during the assembly process...
