摘要

由于现有刮板输送机链轮轮齿磨损测量手段不具备过程简捷、高精度、高效率和低成本等优势，基于聚焦形貌恢复，设计了一种链轮轮齿序列图像采集装置。通过控制该装置运动模块移动，实现工业相机与某个轮齿轴向与周向的对中，进而控制轮齿径向步进电机每步进一次，采集一帧照片，重复此循环过程100次，完成该轮齿序列图像的采集。实验测试结果表明，该序列图像采集装置能够快速地完成轮齿对中并采集到清晰的轮齿序列图像，可为刮板输送机链轮磨损测量提供硬件支撑和积累图像数据样本。

Abstract

Due to the problems of complicated process，low accuracy and efficiency of the existing wear measurement method of scraper conveyor sprocket tooth，a sprocket tooth sequence images acquisition device is designed based on shape from focus.By controlling the movement module of the device，the axial and circumferential alignment between an industrial camera and a sprocket tooth is realized，then control the sprocket tooth radial stepping motor every step，collect a image，repeat the cycle 100 times.And the sequence images acquisition of the sprocket tooth is completed.Test results show that sequence images acquisition device can quickly acquire clear sequence images of the sprocket tooth and provide hardware support and image data samples for the sprocket wear measurement of the scraper conveyor.
