Display method, apparatus, electronic device and computer program product

Abstract

Display method, device, electronic equipment and computer program product, the method includes: collecting depth data of the environment; determining the mapping relationship between each depth value and color combination; generating the depth data of the environment according to the depth data and the mapping relationship A pseudo-color image; displaying the pseudo-color image superimposed on the image of the environment. In this application, the depth data of the environment is mapped to obtain a pseudo-color image, and the pseudo-color image is superimposed on the current environment image for enhanced display, which can make full use of the visual field of low-vision patients without affecting the visual field of low-vision patients. Residual vision and assist it to effectively perceive the distance of objects in the environment.

Description

technical field

[0001] The present application relates to the field of blind guidance technology, and in particular, to display methods, apparatuses, electronic devices and computer program products. Background technique

[0002] Visual disability is a serious public health, social and economic problem worldwide. The main causes of blindness in different economic regions are different. In economically developed regions, age-related macular degeneration, diabetic retinopathy, etc. Cataracts and infectious eye diseases are predominant.
