The present application relates to a kind of based on integrated YOLOv5 and angle texture feature's deformity intersection identification and feature extraction method, comprising the following steps: constructing deformity intersection definition criterion;Typical urban vector road network data is collected and is constructed as grid slice dataset, according to definition criterion, data set is labeled;Multiple YOLOv5 main network is trained using labeled data set, and integrated using weighted voting method obtains vector deformity intersection identification model;The vector road network to be detected is input into vector deformity intersection identification model, the number of deformity intersection, crop figure and crop frame information are obtained by identification, and the central longitude and latitude coordinates of each deformity intersection are calculated;Using angle texture feature algorithm, the number of road intersection in deformity intersection crop figure, included angle and deflection angle are identified, and deformity intersection feature distribution data set is constructed.Compared with prior art, the present application realizes the fast identification and positioning of deformity intersection in large-scale vector road network, and can automatically extract geometric features in deformity intersection.

The utility model belongs to the field of packaging machinery, and provides an automatic support separating machine which comprises a rack, a stock bin, a feeding device, a damping device and a material taking device. Wherein the stock bin is mounted on the rack and comprises protective plates which are arranged in parallel at intervals; the feeding device comprises a pushing head extending into the stock bin and a feeding driving mechanism in transmission connection with the pushing head; the damping device comprises damping blocks installed on the protective plates on the two sides, and the damping blocks form a sawtooth surface which is located in the stock bin and inclines relative to the protective plates. The material taking device comprises a suction cup used for taking materials and a material taking driving mechanism which is in transmission connection with the suction cup and used for driving the suction cup, and further comprises a negative pressure pipe which is connected with the suction cup and used for providing negative pressure for the suction cup, and a deflation valve is arranged on the negative pressure pipe.
