The invention provides a fully-mechanized working face rear scraper conveyor linearity determination device and a pull-move system, and the linearity determination device comprises a processing moduleand a plurality of image recognition tracing modules. By means of the image recognition and tracing technology, a running track of a set target in each section scraper unit of a fully-mechanized working face rear scraper conveyor is recognized and traced, a track line is depicted through an image processing method, the running track of each set target is taken as the line segment of each scraperunit, finally the line segments of the multiple scraper units are spliced to form the track line of the fully-mechanized working face rear scraper conveyor, the track line of the fully-mechanized working face rear scraper conveyor is compared with an ideal track line, and the linearity of the fully-mechanized working face rear scraper conveyor is determined. The fully-mechanized working face rearscraper conveyor linearity determination device and the pull-move system are simple, the reliability is good, and the accuracy is high.
