AI Technical Summary

Technical Problem

Existing TOF light sources are not convenient for adjusting the near and far focal length of the light source emitter in different usage scenarios, resulting in inconsistent recognition accuracy of TOF camera modules.

Method used

An array-based Time-of-Flight (TOF) light source and system was designed. By using symmetrically distributed connecting structures on the outside of the TOF camera module and adjusting the rotation and spacing of convex and concave lenses, the system can switch between near-focus and far-focus effects, thereby enhancing the accuracy of light source recognition.

Benefits of technology

By adjusting the rotation and spacing of the lenses, the recognition accuracy of the TOF camera module in different scenarios has been improved, meeting the recognition needs of different application scenarios.

Abstract

The utility model relates to TOF light source technical field, and disclose an array TOF light source, including casing structure and set up in the TOF signal processor of casing structure inside, the one side end face of casing structure is fixed with TOF camera module and light source emission module, and lens conversion unit includes annular support frame and fixedly set up in the connecting structure of annular support frame inboard, and the connecting structure symmetrical formula distribution is outside TOF camera module, and the inside fixed setting of connecting structure of TOF camera module one side is convex lens, and the inside fixed setting of connecting structure of TOF camera module other side is concave lens. The array TOF light source and system, through the connecting structure corresponding with light source emission module of conversion, can increase the near focus effect or far focus effect of light source emission module respectively, and improved the light source recognition precision of TOF ranging system, solved the problem that the existing TOF light source is inconvenient to adjust near far focus recognition effect according to application scene when using.
