Title:
OFFSHORE CURRENT DETECTION METHOD BASED ON BINOCULAR CAMERA
Document Type and Number:
WIPO Patent Application WO/2021/042490
Kind Code:
A1
Abstract:
An offshore current detection method based on a binocular camera, wherein same belongs to the field of computer vision and the technical field of safety assurance. The method comprises the following steps: firstly, training a convolutional neural network for recognizing an offshore current; secondly, during an actual detection process, recognizing, by means of the trained convolutional neural network, whether an offshore current is present in a sea wave image collected by a binocular camera; and finally, locating the recognized offshore current. According to the method, three-dimensional information of an offshore current can be acquired on the basis of binocular stereoscopic vision, and relatively accurate offshore current location information can be acquired in a timely manner; and the method is simple and highly operable, and relevant staff can mark the location of a sand beach on the basis of the three-dimensional information of the offshore current to warn tourists, thereby reducing the occurrence of drowning accidents caused by an offshore current.
