摘要:
针对继电保护室巡检空间狭小,设备巡检拍摄的图像难免存在畸变,对设备的安全可靠运行具有一定影响的问题,提出了对图像畸变校正和图像拼接方法。首先,对继电保护室保护屏柜图像的倾斜及畸变特征量进行分析,通过寻找棋盘格的角点,对图像进行倾斜及畸变矫正;接着,基于特征提取、特征匹配及图像配准实现图像匹配;最后,通过图像拼接,得到清晰完整的所需图像。以某电力二次保护屏柜的畸变图像组为例,应用所提图像处理技术,验证了所提算法技术能够有效解决小空间内图像畸变和不完整的问题,获得狭小空间和一定俯仰角度下的无畸变图像。
Abstract:
Aiming at the problem of limited inspection space in the relay protection room and inevitable distortion in the images captured during equipment inspection , which has a certain impact on the safe and reliable operation of the equipment , image distortion correction and image stitching methods are proposed. Firstly , the tilt and distortion characteristics of the protective screen cabinet image in the relay protection room are analyzed , and the tilt and distortion of the image are corrected by searching for the corners of the chessboard grid ; next , image matching is achieved based on feature extraction , feature matching , and image registration ; finally , through image stitching , a clear and complete desired image is obtained.Taking the distorted image group of a certain power secondary protection cabinet as an example , the image processing technology proposed is applied , and the results fully verify that the proposed algorithm technology can effectively solve the problem of image distortion and incompleteness in small spaces , and obtain undistorted images in narrow spaces and certain elevation angles.
