Collaborative robot high-precision multi-sensor fusion distance measuring system

The invention provides a collaborative robot high-precision multi-sensor fusion distance measurement system, and the system comprises a collection layer which is used for collecting an acoustic panoramic imaging picture, multi-sensor distance measurement data and an optical panoramic imaging picture around a collaborative robot; the fusion layer is used for performing feature extraction and feature association fusion on the acoustic panoramic imaging picture, the multi-sensing distance measurement data and the optical panoramic imaging picture to obtain a corresponding fusion result; the output layer is used for constructing a three-dimensional panoramic model around the collaborative robot based on the fusion result and a point cloud model construction method, and determining a corresponding distance measurement result based on the three-dimensional panoramic model; the method is used for adopting a plurality of sensors, utilizing redundancy and complementary characteristics of the sensors and obtaining rela
