The invention provides an elevator steel wire rope safety detection method and device based on machine vision, and relates to the technical field of elevator safety. The method comprises the steps that according to a steel wire rope detection instruction, light source parameters are adjusted, and an elevator is controlled to operate according to detection parameters; according to the initial acquisition image evaluation result of the to-be-detected elevator steel wire rope, an acquisition adjustment parameter is generated to control an image acquisition device to perform image acquisition of the to-be-detected steel wire rope, a defect feature evaluation result is obtained, and a stress uniformity evaluation result is obtained based on stress information acquisition; and obtaining a safety detection result of the to-be-detected steel wire rope according to the defect characteristic evaluation result and the stress uniformity evaluation result. The technical problems that in the prior art, an elevator steel wire rope safety detection result is low in accuracy, and the current actual operation damage condition of an elevator steel wire rope cannot be truly reflected are solved. The technical effects that the detection result truly reflects the actual operation loss condition of the equipment, and management personnel can conveniently master the elevator safety condition in time are achieved.
