Berthing assist system and method based on binocular stereoscopic vision

Abstract

The invention provides a berthing assist system and method based on binocular stereoscopic vision. The system is composed of a data collection platform and a data processing platform. The data collection platform comprises a data collection module, and the data collection module composed of a binocular camera and an embedded processor realizes the function of data collection. The data processing platform comprises a data processing module, a data storage module and a data transmission module, and the data processing platform uses an industrial control computer or a high-performance embedded device to realize functions of the data processing, storage and processing modules. Binocular (left and right) images, the contour of a harbor, the distance/angle between a ship and the harbor and early warning information are transmitted to an external client in a wired or wireless manner to assist berthing, or transmitted to a display terminal to help safe work of a ship operator. The range finding technology based on stereoscopic vision is low in cost, and abundant environment information can be obtained.

Description

technical field [0001] The invention relates to the technical field of ship berthing, in particular to a ship berthing assistance system and method based on binocular stereo vision. Background technique [0002] When the ship is berthing, if the speed is too fast or the angle is too large, it is easy to cause safety accidents such as the ship hitting the dock. The berthing of early ships mainly relied on the experience of the crew, and the reliability was poor. In order to ensure safety, it is necessary to use the auxiliary berthing system to obtain information such as the speed and angle of the ship relative to the wharf in real time and reliably, so as to assist the berthing personnel to work safely. Unmanned ships also need to obtain real-time environmental information from the outside world when berthing at the dock to carry out autonomous control and safe docking. In particular, it is necessary to obtain information such as the distance and angle of the ship relative ...
