Target detection method and device

The invention relates to the technical field of computers, in particular to a target detection method and device. The method comprises the steps that image processing is carried out on a to-be-detected image, a first image is obtained, and the first image is an area where a digital port area in the to-be-detected image is located; performing information identification on the first image by adopting a target detection algorithm Yolov5 to obtain digital information and indicator light information in the first image; according to the number information and the indicator light information, obtaining distance information between any number and any indicator light, and according to the distance information, determining a target detection result corresponding to the to-be-detected image, the target detection result is used for indicating the lighting state of the indicating lamp corresponding to any number or the number corresponding to the indicating lamp in the target lighting state. According to the invention, th
