Depth map display method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention relates to the field of image processing, and discloses a depth map display method and device, electronic equipment and a storage medium. In some embodiments of the invention, the display method of a depth map comprises the following steps: acquiring a normal vector of each pixel in the depth map; enhancing the depth information represented by the normal vector of each pixel based on a preset illumination model to obtain an intensity coefficient of each pixel; and displaying the depth map according to the intensity coefficient of each pixel. According to the embodiment, regional details with relatively small depth changes can be displayed.

Description

technical field [0001] The embodiments of the present invention relate to the field of image processing, and in particular, to a display method, a display device, electronic equipment, and a storage medium of a depth map. Background technique [0002] Currently, the depth map is usually displayed by mapping from depth values ​​to grayscale values ​​or by mapping from depth values ​​to color spaces. Specifically, the meaning of the pixel value in the depth map is the distance value of each point in the scene from the sensor. In the process of displaying the depth map through the mapping from the depth value to the gray value, the depth map can be displayed by mapping the distance value to the gray value. However, in high-precision scenes, when using millimeters as the distance unit and using grayscale images to display depth maps, conventional displays cannot display more than 256 grayscales, which has great limitations; for relatively small depth changes The display of reg...

Problems solved by technology

However, in the process of displaying the depth map through the mapping from the depth value to the color space, the visualization effect is not ideal in some scenes due to the weak display of the details of the area with relatively small depth changes.

[0003] Therefore, the current depth map display method is weak in displaying the details of regions with relatively small depth changes. Observation details in the area
