Abstract

Provided in the embodiments of the present application are a multi-information-fusion-based binocular ranging method and system for an autonomous rail rapid transit. Parameters of a binocular camera are calibrated A laser emitter and the binocular camera are properly mounted according to a safety early-warning distance and are corrected. A road image is input into a target detection algorithm, a target is output, and an image position of the target is determined. An SGBM stereo matching algorithm is called to calculate a parallax. An initial ranging distance of the target is calculated according to a focal length, an optical center distance and the parallax. Due to changes in a road environment and non-linear effects of camera imaging, when the target moves to a position at the safety early-warning distance, a reference baseline formed by two beams of linear structured light is used to calculate a ranging calibration coefficient at the current moment. The calibration coefficient is used to correct an initial ranging result of the target to obtain a final ranging result, thus improving the binocular ranging precision for an autonomous rail rapid transit.
