Abstract

The invention provides a depth estimation method, device and system, and a computer readable storage medium. The method comprises the steps of: correcting and transforming the acquired color image andinfrared image respectively to obtain an undistorted virtual perspective image; estimating the parallax between the corrected and transformed color image and the corrected and transformed infrared image to obtain a parallax image; filtering the parallax image; and inversely correcting and transforming the filtered parallax image to obtain a depth image aligned with the original color image. The depth estimation method, device and system can estimate the depth on a mobile terminal, and can accurately obtain the depth information of a scenario.

Description

technical field [0001] The present invention relates to the field of artificial intelligence, in particular to a method, device, system and computer-readable storage medium for depth estimation based on image processing technology. Background technique [0002] Depth information is of great significance in the field of computer vision. The accuracy of the depth map has an important impact on applications such as 3D reconstruction, fine image segmentation, light effect rendering, and facial animation. In order to obtain the depth information of the image, people can calculate the depth information of the scene through the images obtained by multiple cameras. The traditional solution generally uses a dual-color camera to generate a depth map based on a stereo matching algorithm. However, for mobile devices such as mobile phones, the dual-color camera module is large in size and expensive. Areas, etc., are prone to deep recovery errors. Contents of the invention [0003] Co...
