Abstract

The invention provides a power control method and device for a light emitting module of a TOF camera, by acquiring a depth map of a photographed object; determining power control information of the light emitting module according to the depth map; and controlling the TOF camera according to the power control information The power of the light emitting module is adjusted. The method provided by this embodiment overcomes the difference in the distances of the photographed objects within the working distance, but uses the same transmission power , resulting in the problem of more power consumption and greater heat generation of the light emitting module, so the TOF measurement accuracy is effectively improved and the energy consumption is reduced. The method and device provided in this embodiment are especially suitable for taking depth maps of distant objects shoot.

Description

technical field [0001] The invention relates to the technical field of image processing, and in particular, to a power control method and device for a light emission module of a TOF camera. Background technique [0002] In the prior art, according to the actual usage scenario, the manufacturer will set the light emitting module (such as VCSEL or LED) of the TOF camera to a fixed power, so the power of the light emitting module will not be adjusted according to the distance of the shooting object. The product works at a fixed distance. Within the working distance, no matter the distance of the subject, one type of power is used, which will cause the light source to generate more heat, which will affect the measurement accuracy, and the device will consume more power due to heat. [0003] Therefore, the prior art needs to be further improved. SUMMARY OF THE INVENTION [0004] In view of the deficiencies in the above-mentioned prior art, the object of the present invention i...
