摘　　要：野外施工过程中,锥形混凝土电杆开裂检验的抽检需求是目前市场上亟待解决的问题。针对锥形混凝土电杆开裂检验过程中稍端偏转量的采集和提取方式进行了深入分析,研究并设计了基于图像处理技术的稍端偏转量测量仪,该系统主要由线光源、测试箱、图像采集相机、采集板卡、Lora模块、Matlab程序等6部分构成,测试箱中有定位板、幕布、图像采集相机、采集板卡、Lora模块。线光源发出的光在定位板和幕布的作用下,在箱体内形成光斑,通过在对应的检测拉力点采集光斑位置变化量,从而实现快速、准确的锥形混凝土电杆稍端偏转量采集。In the process of field construction, the sampling inspection demand for cracking inspection of conical concrete pole is an urgent problem to be solved in the market. In this paper, the acquisition and extraction methods of tip deflection in the cracking inspection of conical concrete pole are deeply analyzed, and a tip deflection measuring instrument based on image processing technology is studied and designed. The system is mainly composed of six parts: linear light source, test box, image acquisition camera, acquisition board, Lora module and matlab program. There are positioning board, curtain, image acquisition camera, acquisition board card and Lora module in the test box. The light emitted by the linear light source forms a light spot in the box under the action of the positioning plate and curtain. The change of the spot position is collected at the corresponding detection tension point, so as to quickly and accurately collect the deflection of the slightly end of the conical concrete pole.
