Abstract

The invention discloses a method for obtaining a depth map by a monocular camera. The method includes: step 1: refitting the camera lens: attaching three color filters of R, G and B to the inner surface of the camera lens respectively ; Step 2: Obtain an image using the refitted camera lens, and perform numerical calculation L on the image; Step 3: Obtain an image depth map based on the calculated value L, realizing the technical effect of easy acquisition of image depth information and low cost.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a method for obtaining a depth map by a monocular camera. Background technique [0002] Obtaining the distance of a point in the scene to the camera is one of the important tasks of computer vision. The distance of a point in the scene to the camera can be represented by a depth map (Depth Map), that is, each pixel in the depth map represents the distance between a point in the scene and the camera. There are many ways to obtain a depth map, for example, the depth map can be obtained based on sensors such as lasers, ultrasonic waves, and cameras. Among them, obtaining a depth map based on a camera is a key research project of computer vision today. There are roughly two methods for obtaining a depth map based on a camera: obtaining a depth map through a monocular camera, and obtaining a depth map through a binocular (multi-purpose) camera. The latter research has been v...
