Depth acquisition method and device, computer readable storage medium and computer equipment

Abstract

The invention discloses a depth acquisition method. The depth acquisition method is applied to an electronic device. The depth acquisition method comprises the steps that multiple pieces of initial depth information of a target object are acquired; the initial depth information is processed to obtain multiple pieces of intermediate depth information; and the intermediate depth information is merged to obtain final depth information. The invention furthermore discloses a depth acquisition device, a non-volatile computer readable storage medium and computer equipment. The final depth informationis formed by merging the intermediate depth information, the intermediate depth information is obtained by processing the initial depth information, the intermediate depth information can be the part, most capable of reflecting real depth information of the target object, in the initial depth information, and therefore the accuracy of the final depth information obtained by merging the intermediate depth information is high.

Description

technical field [0001] The present invention relates to the field of image technology, in particular to a depth acquisition method, a depth acquisition device, a non-volatile computer-readable storage medium and computer equipment. Background technique [0002] After the laser projector projects the laser pattern to the target object, the imaging device obtains the laser pattern modulated by the target object, and the processor can further process the modulated laser pattern to obtain the depth information of the target object. The target object has the most suitable laser pattern for it. When the distance span between the target object and the laser projector is large, the laser pattern projected by the laser projector at one time cannot be well adapted to the entire target object, resulting in The accuracy of the finally obtained depth information is not high. Contents of the invention [0003] Embodiments of the present invention provide a depth acquisition method, a d...
