Title:

LABORATORY SPATIAL WAVE REAL-TIME MEASUREMENT METHOD BASED ON VISUAL EDGE DETECTION

Document Type and Number:

WIPO Patent Application WO/2023/035544

Kind Code:

A1

Abstract:

A laboratory spatial wave real-time measurement method based on visual edge detection, comprising the following steps: S1: calibrating a camera (4); S2: photographing a wave surface image under wave motion by means of the camera (4), and sending the wave surface image to a digital signal processing system (5); S3: the digital signal processing system (5) performing visual edge detection on the received wave surface image; S4: the digital signal processing system (5) detecting a water level line (2) and a wave surface feature in the wave surface image; S5: the digital signal processing system (5) performing coordinate conversion on the detected water level feature; and S6: storing the coordinate conversion result, and displaying the coordinate conversion result on a wave surface identification display interface in real time. The problem that existing measurement techniques cannot realize real-time detection of a spatial wave surface and real-time measurement of a water level for wave motion is solved.
