Method and system for amplitude-frequency regulation of artificial retina based on depth vision

Abstract

The invention discloses an artificial retinal stimulation amplitude frequency control method and system based on depth vision. The method comprises the following steps: collecting scene images in front by two cameras arranged side by side and horizontally on the same vertical plane; generating a two-dimensional depth map with scene depth information by two frames of scene images collected by two cameras are synchronized, and the two-dimensional depth map with scene gray level information and depth information is abstracted and outputted. If gray level information is selected, encoding of the electrode stimulation is generated according to the surface gray level information of the observation object; if the user selects the depth information, generating an encoding of the electrode stimulation according to the surface distance of the observation object. The present invention can visually give a blind person using an artificial retinal system the ability to perceive the distance of an object.

Description

Technical field [0001] The invention belongs to the field of artificial vision, and relates to a method and system for adjusting the amplitude and frequency of an artificial retina based on depth vision. Background technique [0002] With the continuous advancement of science and technology, as early as 2010, an artificial retina system was developed. The most basic concept is to convert light signals into electrical signals. The use of electrical signals to stimulate cells in the inner layer of the retina is the blind person’s sense of light. At present, this technology is still a research hotspot in the field of visual restoration. Many companies and research institutes have made efforts in related fields, and constantly proposed improvement plans to improve the effect of the system and improve the quality of life of patients. Among them, two directions are the focus of improvement: the first direction is to increase the electrode density; the second direction is to process i...
