Embodiment Construction

[0028]In order to make the purpose, technical solutions and advantages of the present application, the present application will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended to explain the present application and is not intended to limit the present application.

[0029]The present invention proposes a depth map coloring method based on a single-grade depth camera, and the present method includes the following three steps.

[0030]Step 1. Use an infrared camera, a colored camera and an infrared speckle projection meter, form a small single-grade camera, infrared speckle-projection instrument to the survey of the survey, the infrared camera and color camera synchronization Collect images. Infrared cameras, color cameras and infrared speckle dot array projectors are placed horizontally, and the three are on the same horizontal line. Among them, the distance be...

Abstract

The invention discloses a depth map colorization method based on a monocular depth camera, and the method comprises the steps: a miniature monocular depth camera through an infrared camera, a color camera and an infrared speckle spot array projector are formed, and the infrared speckle spot array projector projects a random speckle pattern to a detected scene; an infrared camera and a color camera synchronously acquire images, and the corresponding relationship between the speckle image shot by the infrared camera and the color image shot by the color camera is calculated through the depth map, so that colorization of the depth map is realized, and the depth map is endowed with color texture information of a measured scene. Compared with an existing depth map colorization method, the depth map colorization method has the advantages of being full-automatic, accurate in algorithm and low in time complexity.

Description

Technical field[0001]The present invention relates to the field of computer graphics, and more particularly to a depth map colorization method based on a single-grade depth camera.Background technique[0002]In the computer vision system, the three-dimensional scene information provides more possibilities for image segmentation, target detection, object tracking, and other computer visual applications, while depth images are obtained as a common way of common three-dimensional scene information. A wide range of applications. The grayscale value of each pixel point of the depth image can be used to characterize a far away from a point of view in the scene.[0003]Depth image is also referred to as a distance image, refers to an image of the distance (depth) as a pixel value from the image collector to the field, which directly reflects the geometry of the scene visible surface. .[0004]RGB color mode is a color standard in the industry, which is a variety of colors through changes in red ...
