Problems solved by technology

[0003] However, there are certain deficiencies in the above methods
For example, RGB binoculars use two sets of cameras, which require two sets of complete hardware structures, so the cost of the system is high, and the power consumption of the system is also high. At the same time, the system is relatively large; At present, there are few suppliers’ solutions, the system consumes high power and lacks RGB information, while structured light requires the cooperation of laser emitting equipment, and the system cost is high

Embodiment Construction

[0028] The solutions of the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, for purposes of illustration rather than limitation, specific details, such as specific system architectures, interfaces, and techniques, are set forth in order to provide a thorough understanding of the present application.

[0030] The terms "system" and "network" are often used interchangeably herein. The term "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations. In addition, the character " / " in this article generally indicates that the contextual objects are an "or" relationship. In addition, "many" herein means two or more than two.

Abstract

The invention discloses a depth image acquisition method, device and system, and a computer readable storage medium, and the method comprises the steps: obtaining multiple frames of original images collected by a monocular color-infrared image collection module, each frame of original image comprising infrared pixel information, the phase shift angle between the original images of the adjacent frames is 2pi / N, and N is a positive integer greater than 2; determining depth information corresponding to the infrared pixel information based on the infrared pixel information in at least N frames of continuous original images; and generating a depth image based on the depth information corresponding to the infrared pixel information. According to the scheme, the depth image can be acquired under the condition of low cost.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to a depth image acquisition method, device, system, and computer-readable storage medium. Background technique [0002] With the development of optical measurement technology and computer vision, various techniques and products for obtaining depth images have been developed. At present, there are three mainstream depth cameras in the industry: one is the TOF (Time Of Flight) system. The TOF system obtains a 3D image from the distance or depth between the camera and the object to be identified, and uses light emission that illuminates the object to be identified. The time difference between the time and the light reception time of the reflected light from the identified object measures distance or depth; the second is RGB binocular, binocular stereo vision is an important form of machine vision, it is based on the principle of parallax and uses imaging equipme...
