Embodiment Construction

[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0028] Such as figure 1 As shown, the present invention discloses an angle measurement method based on automatic interpretation of visual light spots. The method includes the following steps:

[0029] S1. Collect the image of the light spot continuously emitted by the laser transmitter on the turntable taken by the calibrated high-speed camera and hit on the target plane;

[0030] S2. Binarize the collected images; perform edge detection on the binarized image, circle the contour of the light spot and search for connected areas, and average the pixels in the connected areas;

[0031] S3. Convert t...

Abstract

The invention discloses an angle measuring method and an angle measuring system based on automatic interpretation of visual light spots. The angle measuring method comprises the steps of: acquiring light spot images which are shot by means of a calibrated high-speed camera, continuously emitted by means of a laser emitter on a turntable and irradiated on a target plane; processing the acquired images by adopting a binarization method; performing edge detection on the images after binarization processing, circling a light spot contour and searching in a connected region, and averaging pixels inthe connected region; and converting the average pixel into physical coordinates on the target plane, and calculating a rotation angle of the turntable according to a trigonometric formula. The anglemeasuring system corresponds to the angle measuring method. The angle measuring method and the angle measuring system have the advantages of low economic cost, simple operation and high precision.

Description

Technical field [0001] The invention belongs to the technical field of intelligent control vision, and in particular relates to an angle measurement method and system based on automatic interpretation of visual light spots. Background technique [0002] The measurement of the rotation angle of the turntable is the basis of related problems such as target position detection and speed measurement. The realization of the automatic interpretation of the turntable's rotation angle is a key factor to measure its level of intelligence. At present, there are many methods for measuring the rotation angle of the turntable, but individual links require more or less human participation, and the manual reading efficiency is low and the accuracy is not high. Although the binocular vision system can improve a certain degree of efficiency, it has a high economic cost and a complicated structure. Summary of the invention [0003] The purpose of the present invention is to provide an angle measure...
