The invention discloses a measurement device for the swing angle of a multi-sling bridge crane. The multi-sling bridge crane comprises a bridge crane trolley provided with first lifting ropes. The measurement device for the swing angle of the multi-sling bridge crane is characterized in that the measurement device comprises a swing angle calculation and control computer, a fan-shaped plane infrared light emitter, a swing angle detection camera, lifting rope vertex markers and a video image processor; the fan-shaped plane infrared light emitter is used for emitting fan-shaped infrared light, and the light encounters one or more of the first lifting ropes, so that light spots are left; the swing angle detection camera is used for shooting images of the first lifting ropes; the video image processor is used for receiving the images of the first lifting ropes and finding the positions of the light spots and the lifting rope vertex markers; the swing angle calculation and control computer, the fan-shaped plane infrared light emitter and the video image processor are arranged on a second lifting rope, and the second lifting rope moves along with moving of the bridge crane trolley; and the swing angle calculation and control computer works out the position coordinates of the light spots and the lifting rope vertex markers, and thus a swing angle value is obtained. By adoption of the measurement device for the swing angle of the multi-sling bridge crane, the swing angle of the bridge crane can be detected accurately, and the measurement device has the advantages of being low in cost and high in antijamming capability.

The invention discloses an image steganalysis method based on adversarial training and critical path extraction, and the method comprises the steps: respectively inputting a to-be-detected image intoa steganalysis module after adversarial training and a steganalysis module based on critical path extraction, wherein the to-be-detected image comprises a non-steganography image, a traditional steganography image and an adversarial embedded steganography image, and the traditional steganography image and the adversarial embedded steganography image belong to the category of the steganography image; obtaining the probability that the to-be-detected images output by the two modules are steganography images, and obtaining the probability that the final to-be-detected images are steganography images by combining the weights of the two modules and adopting a weighted fusion mode. According to the method, the steganography image generated through adversarial embedding can be detected, and meanwhile, the problem that the accuracy of a traditional steganography image and a non-steganography image is reduced due to adversarial training is balanced to a certain extent.
