Depth information processing method and system and electronic equipment

Abstract

The invention discloses a depth information processing method and system and electronic equipment. The depth information processing method comprises the steps that multiple pieces of partition depth information are acquired, the multiple pieces of partition depth information are acquired by detecting multiple view field partitions through a partition TOF according to a certain time sequence, and the multiple view field partitions jointly form a complete target view field; and according to the partition arrangement of the plurality of view field partitions, the plurality of partition depth information in a splicing manner are processed to obtain complete depth information corresponding to the target view field.

Description

technical field [0001] The invention relates to the technical field of TOF, in particular to a depth information processing method, a system thereof, and an electronic device. Background technique [0002] At present, among the mainstream solutions of 3D sensing technology, TOF (Time of Flight) technology has been widely concerned and applied in industries such as smartphones due to its advantages of small size, low error, direct output of depth data and strong anti-interference. From the perspective of technical implementation, there are two types of TOF: one is direct ranging TOF (dTOF for short), that is, the distance is determined by emitting and receiving light, and measuring the flight time of photons; the other is a very mature non- Direct ranging TOF (iTOF), that is, by measuring the phase difference between the transmitted waveform and the received waveform to convert the time of flight to determine the distance. However, the direct ranging method transmits the lig...

[0003] However, the detection distance of the existing direct ranging TOF is proportional to the power consumption, that is to say, the longer the detection distance of the direct ranging TOF, the higher the required power consumption, which makes the existing direct ranging TOF In order to achieve longer-distance detection to meet the needs of application scenarios such as VR / AR, TOF has to configure a higher-power light source, resulting in the existing direct ranging TOF often performing short-distance measurements with higher power consumption. and long-distance detection, thereby causing waste of resources and affecting the application and promotion of TOF technology
