The invention provides a visual detection system and method for the length of a pipe body, and belongs to the technical field of industrial automation, and the visual detection system for the length of the pipe body comprises an end marking module, a camera module and a controller. Wherein the camera module defines a detection area for shooting, and shoots a detection image of a to-be-detected pipe body in the detection area; the end marking module comprises two groups of marking lasers, and the two groups of marking lasers emit laser beams on the two sides of the detection area to mark the end faces of the two ends of the to-be-detected pipe body; and the controller is electrically connected with the camera module, acquires the detection image, and calculates the actual length of the to-be-detected pipe body based on the position information of the to-be-detected pipe body in the detection image. According to the visual detection system and method for the length of the pipe body, a plurality of pipe bodies c
