DEVICE FOR HANGER DETECTION BY IMAGE PROCESSING

摘要

This device for hanger detection by image processing detects hangers (6) in an image, and is equipped with: a line sensor camera (2) that captures an image of hangers (6) from the roof of a vehicle (1), the hangers (6) being installed with equal spacing and support a trolley line (4); and an image processing unit (3) that is installed within the vehicle (1) and analyzes the image obtained by the line sensor camera (2). The device for hanger detection is configured such that the image processing unit (3) is provided with: a gray scale-top hat processing unit (31a) which sequentially subjects each line sensor image input from the line sensor camera (2) to the gray scale-top hat processing in the imaging line direction and time direction of the line sensor camera (2) and acquires a gray scale-top hat image where the hangers (6) in the image are highlighted; and a hanger detection unit (31b) which detects the hangers (6) from the gray scale-top hat image.
