Circuit system and equipment based on single optical device and considering distance sensing and imaging

Abstract

The invention discloses a circuit system and equipment based on a single optical device and considering distance sensing and imaging. The circuit system comprises single photon avalanche diodes, quenching and shaping circuits, a clock module, a high-speed counter, a control unit and a data output. The circuit equipment comprises a central controller, a photosensitive array and reading circuit system, a retractable optical filter, a pulse laser, a receiving optical system and a transmitting optical system. According to the circuit system and equipment, single-photon light sensing units can alternately work in a distance sensing mode and an imaging mode, due to the fact that the same light sensing units conduct distance and light intensity sensing on the environment in a time-sharing mode, obtained three-dimensional information and image information are matched and can be fused for use without subsequent excessive data processing, and the effective data obtaining efficiency of the systemis improved. The problems of large later-period data processing difficulty and low obtained effective data due to the fact that indexes such as the frame frequency, the view field angle and the resolution of a laser radar and a camera are usually not matched in the prior art are solved.

Description

technical field [0001] The invention belongs to the field of photoelectric detection, and in particular relates to a circuit system and equipment based on a single optical device that takes into account both distance perception and imaging. Background technique [0002] With the continuous development of science and technology, in the fields of surveying and mapping and unmanned driving, 3D information and image information of the environment are usually required at the same time. In traditional applications, the combination of lidar and camera is used to combine the data of radar and camera into space Matching realizes the fusion of three-dimensional information and image information, and then obtains the required data. In this application method, since the lidar and the camera usually do not match in terms of frame rate, field of view angle, and resolution, the difficulty of later data processing increases and the effective data obtained decreases.
