A circuit system and device based on a single optical device taking into account both distance perception and imaging

Abstract

The invention discloses a circuit system and equipment based on a single optical device that takes into account both distance perception and imaging, wherein the circuit system includes a single photon avalanche diode, a quenching and shaping circuit, a clock module, a high-speed counter, a control unit, and a data output; the circuit equipment includes Central controller, photosensitive array and readout circuit system, retractable optical filter, pulse laser, receiving optical system, and emitting optical system. The single-photon photosensitive unit of the present invention can alternately work in the distance perception mode and the imaging mode. Since the same photosensitive unit senses the distance and light intensity of the environment in a time-sharing manner, the acquired three-dimensional information and image information are matched without too much follow-up Data processing can be integrated and used to improve the efficiency of effective data acquisition in the system. It solves the problem that in the prior art, due to the frame rate, field of view angle and resolution and other indicators of the lidar and the camera usually do not match, the post-data processing is difficult and the effective data obtained is low.

Description

Technical field [0001] The present invention belongs to the field of photoelectric detection, specifically relates to a circuit system and apparatus based on a single light device taking into account both distance perception and imaging. Background [0002] With the continuous development of science and technology, in the fields of surveying and mapping and unmanned driving, usually at the same time the need for environmental three-dimensional information and image information, traditional applications, is the use of lidar and camera cooperation, the radar and camera data to do spatial matching, to achieve three-dimensional information and image information fusion, and then get the required data. In this application method, because the lidar and camera usually do not match in the frame rate, field of view angle and resolution and other indicators, the difficulty of post-processing data processing is increased, and the effective data obtained is reduced. [0003] In view of the ab...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a circuit system and equipment based on a single-optical device that takes into account both distance perception and imaging, which solves the problem of frame rate and field of view angles between laser radar and camera in the prior art. The indicators usually do not match with the resolution, which makes the later data processing more difficult and the effective data obtained decreases.
