Embodiment 1

[0035] This embodiment provides a method for acquiring depth information, which is applied to terminal devices including dual cameras, for example, mobile terminals such as mobile phones, tablet computers, personal digital assistants, AR (Augmented Reality, augmented reality technology) glasses, and can also be applied to mobile terminals with Computing equipment such as a PC (Personal Computer, personal computer) client, a self-service terminal, or a server connected by communication with the dual cameras.

[0036] Such as figure 1 As shown, the depth information acquisition method provided in this embodiment includes:

[0037] Step S101, acquiring two images of the same scene through dual cameras.

[0038] In a specific application, the dual camera can be a symmetrical dual camera or an asymmetrical dual camera. The symmetrical type means that the parameters of the two cameras included in the dual camera are the same, and the asymmetrical type means that the parameters of t...

Embodiment 2

[0122] Such as Figure 10 As shown, this embodiment provides a depth information acquisition system 10, which is applied to a terminal device including dual cameras, and is used to execute the method steps in Embodiment 1. The system may be a terminal device processor or a software program in the processor system.

[0123] In a specific application, the processor may be a central processing unit (Central Processing Unit, CPU), and may also be other general-purpose processors, a digital signal processor (Digital Signal Processor, DSP), an application specific integrated circuit (Application Specific Integrated Circuit) , ASIC), off-the-shelf programmable gate array (Field-Programmable Gate Array, FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. A general-purpose processor may be a microprocessor, or the processor may be any conventional processor, or the like.

[0124] The depth information acquisition sy...

Embodiment 3

[0138] Such as Figure 11 As shown, this embodiment provides a terminal device 11, which includes: a processor 110, a memory 111, and a computer program 112 stored in the memory 111 and operable on the processor 110, such as a depth information estimation program . When the processor 110 executes the computer program 112, it realizes the steps in the above embodiments of the depth information acquisition method, for example figure 1 Steps S101 to S105 are shown. Alternatively, when the processor 110 executes the computer program 112, the functions of the modules in the above-mentioned device embodiments are realized, for example Figure 10 The functions of modules 101 to 105 are shown.

[0139] Exemplarily, the computer program 112 can be divided into one or more modules, and the one or more modules are stored in the memory 111 and executed by the processor 110 to complete the present invention. The one or more modules may be a series of computer program instruction segmen...

Abstract

The method is suitable for the technical field of image processing. The invention provides a depth information acquisition method, a depth information acquisition system and terminal equipment. Two images in the same scene are acquired through double cameras, the matching cost of each pixel point in the two images is calculated respectively, and cost aggregation in a preset number of directions isperformed on each pixel point according to the matching cost of each pixel point to obtain a disparity map of the two images, so that the calculation time can be effectively shortened, and the powerconsumption can be reduced; and after the disparity maps of the two images are converted into the depth maps, the depth maps are respectively mapped back to the two images, and the depth information can be directly applied to the original image.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a depth information acquisition method, system and terminal equipment. Background technique [0002] At present, the depth information acquisition method based on a terminal device with dual cameras is usually: use dual cameras to simultaneously acquire two images in the same scene, and then use a stereo matching algorithm to find matching pixels in the two images, and calculate the matching The disparity value between the pixel points is converted into the depth information of the objects in the scene. [0003] However, the current depth information acquisition methods have the problems of long calculation time and high power consumption, and the depth information cannot be directly applied to the original image. Contents of the invention [0004] In view of this, the embodiments of the present invention provide a depth information acquisition method, sys...
