Abstract

A method for brightness adjustment of an infrared light source includes obtaining distance between a captured object and the infrared light source; and adjusting the brightness of the infrared light source according to the distance. Thus, when the captured object is relatively far away from a camera lens, the infrared light source can provide infrared light with sufficient brightness, and when the captured object is relatively close to the camera lens, the light-emitting brightness of the infrared light source is properly reduced, thereby reducing the light emission amount of the infrared light source, and avoiding the problem that the infrared light source is set to be maximum brightness for a long time and thus causing the service life of the infrared light source to be shortened and affecting normal work of the camera.

Description

technical field [0001] The invention belongs to the technical field of light source brightness adjustment, and in particular relates to a method and device for adjusting the brightness of an infrared light source, and an optical motion capture camera. Background technique [0002] Optical motion capture systems are widely used in film animation special effects production, large-scale game production, life science research and other fields. In recent years, with the development of virtual reality (Virtual Reality, VR) technology, optical motion capture systems have begun to be applied in the field of VR technology. [0003] The core device of the optical motion capture system is the optical motion capture camera. The optical motion capture camera is mainly composed of an image sensor, a lens, an infrared band-pass filter unit, an infrared light source, and a camera control circuit. The infrared light emitted by the infrared light source irradiates the captured object (human...
