To provide an overhead power line metal fitting detection device which can correctly detect only an overhead power line metal fitting, and an overhead power line metal fitting detection method.SOLUTION: An overhead power line metal fitting detection device comprises: a line sensor camera 2 which photographs a trolley wire 4 and an overhead power line facility during travel of a train vehicle 1; a pre-processing part 31a which performs learning of an artificial intelligence function by use of a previously acquired image of an overhead power line metal fitting and an image other than the overhead power line metal fitting; a line sensor image creation part 31b which creates a line sensor image from an image signal inputted from the line sensor camera 2 during travel of the vehicle 1; a brightness correction part 31c which performs brightness correction processing of the image signal for increasing a light-dark difference; an image cut-out part 31d which creates a cut-out image which cuts out the overhead power line metal fitting or a portion other than the overhead power line metal fitting from the line sensor image of which brightness correction processing has been performed; and a metal fitting identification processing part 31e which identifies the overhead power line metal fitting by inputting the cut-out image to the artificial intelligence function.SELECTED DRAWING: Figure 2
