As is shown in Figures 1-2, an automatic detection device for the surface corrosion condition of a harbor operation machine comprises five cameras 2, five movement control devices 3, five fdd-lte wireless communication modules 4, four shadowless lighting sources 9 and a computer 8 also provided with a fdd-lte wireless communication module 4, wherein, each camera 2 is an automatic digital camera with a resolution of 4000*3000 and capable of acquiring clear images, so that the image processing effect in the later stage is ensured; the five cameras 2 are separately fixed to the five movement control devices 3 and are adjacent to the front face, the back face, the left face, the right face and the top face of the to-be-detected harbor operation machine separately.
Each movement control device 3 comprises a transmission device, a first stepping motor 5-1, a second stepping motor 5-2, a third stepping motor 5-3, a motor drive circuit board and a microprocessor, wherein the first stepping motor 5-1, the second stepping motor 5-2 and the third stepping motor 5-3 are disposed on the transmission device, and the motor drive circuit board and the microprocessor are disposed on the transmission device. Specifically, as is shown in Figure 3, each transmission device comprises a front-back transmission mechanism, a left-right transmission mechanism and an up-down transmission mechanism, wherein, the front-back transmission mechanism comprises a first base plate 10-1, two first single-axis sliding rails 10-2 symmetrically fixed to the first base plate 10-1 in parallel, and a second base plate 10-4 movably connected to the two first single-axis sliding rails 10-2 through two sliding blocks separately matched with the first single-axis sliding rails 10-2; the corresponding first stepping motor 5-1 is disposed on the first base plate 10-1 and located at one ends of the two single-axis sliding rails 10-2, and one side of the second base plate 10-4 is connected to an output shaft of the corresponding first stepping motor 5-1 through a first lead screw 10-3; the left-right transmission mechanism comprises two second single-axis sliding rails 10-5 symmetrically fixed to the second base plate 10-4 in parallel and a third base plate 10-7 movably connected to the two second single-axis sliding rails 10-5 through two sliding blocks separately matched with the second single-axis sliding rails 10-5; the corresponding second stepping motor 5-2 is disposed on the second base plate 10-4 and located at one ends of the two second single-axis sliding rails 10-5, and one side of the third base plate 10-7 is connected to an output shaft of the corresponding second stepping motor 5-2 through a second lead screw 10-6; and the up-down transmission mechanism comprises a bracket 10-8 used for fixing the corresponding image acquisition device 2, the corresponding third stepping motor 5-3 is vertically fixed to the third base plate 10-7 to enable an output shaft of the third stepping motor 5-3 to be vertically disposed upwards, and the bracket 10-8 is connected to the output shaft of the third stepping motor 5-3.
Based on the cooperation of the transmission devices and the cameras 2, the cameras 2 are adjusted forwards or backwards in position through the front-back transmission mechanisms 1 according to the dimension of the to-be-detected harbor operation machine, and the distances between the lenses of the cameras and the shoot faces are adjusted, so that the focusing requirement of the cameras is met. Through the left-right transmission mechanisms and the up-down transmission mechanisms, the cameras achieve image acquisition of the shoot faces by performing image acquisition, analysis and processing on a plurality of uniform parts ofthe shoot faces, and thus the image processing speed and accuracy are improved.
The motor drive circuit boards and the microprocessors are disposed on the bottom faces of the first base plates 10-1 of the corresponding transmission devices, wherein each microprocessor is connected to the three corresponding stepping motors 5 through the corresponding motor drive circuit board 6 and controls the first stepping motor 5-1, the second stepping motor 5-2 and the third stepping motor 5-3 independently so as to move the corresponding camera 2 to a preset image acquisition position, and then images of all the parts of the shoot faces are acquired sequentially.
The wireless communication devices 4 are fdd-ltewireless communication modules adaptively equipped with SIM cards in conformity with the fdd-lte communication protocol, such as standard-dimension SIM cards, Micro SIM cards and Nano SIM cards. Data transmission between the five cameras 2 and the computer 8 is achieved through the wireless communication devices 4, and images acquired by the cameras 2 are transmitted to the computer 8 so as to be processed, analyzed and compared. Meanwhile, the computer 8 controls the shoot time of the cameras 2 and the number of images acquired by the cameras 2 through the fdd-lte wireless communication module.
The four shadowless lighting sources 9 are linearly disposed 1000-1500 mm above the top face of the to-be-detected harbor operation machine 1. Through the shadowless lighting sources 9, the cameras 2 can stably acquire clear images of all the surfaces of the to-be-detected harbor operation machine 1, and the detection accuracy is improved.
Based on the fdd-lte wireless communication technique, the automatic detection device for the surface corrosion condition of a harbor operation machine specifically operates as follows: in the process of acquiring surface images in five directions of the harbor operation machine, the shadowless lighting sources 9 distributed above the harbor operation machine are turned on, images of the harbor operation machine are acquired by the five cameras separately, image data are then wirelessly sent to the computer 8 through the fdd-lte wireless communication modules, and after the image data are processed by the computer 8, whether or not the surfaces of the harbor operation machine are corroded are determined, and managers are informed of the surface corrosion condition of the harbor operation machine.
Particularly, as is shown in Figure 4, the specific processing process of the computer 8 comprises the following steps: 51, the microprocessor 7 of each movement control module 2 drives the three corresponding stepping motors to change the shoot position of the corresponding camera 2, so that each shoot plane of the harbor operation machine is evenly divided into 4*4 parts in the initial stage, namely images of 16 parts of the to-be-shot planes are separately acquired by the cameras 2; 52, the 16 color images acquired by the cameras are converted into 256-order gray images serving as standard images; 53, standard data are extracted, specifically, fractal dimensions of the standard images processed in step S2 are extracted through a differential box fractal algorithm and stored in a database; after the harbor operation machine is used for a period of time, the five faces of the harbor operation machine are shot again; 54, the microprocessor 7 of each movement control module 3 drives the three corresponding stepping motors to change the shoot position of the corresponding camera 2, and images of the 16 parts of the to-be-shot planes are acquired by the cameras 2 separately; similarly, the computer 8 converts the received color images into 256-order gray images serving as to-be-detected images; 55, to-be-detected data are extracted, specifically, fractal dimensions of the to-be-detected images subject to gray processing in step S4 are extracted through a fractal algorithm; 56, the corrosion condition is judged: the fractal dimensions of the to-be-detected images are compared with the fractal dimensions of the standard images; if the errors are within the error range set by users, it indicates that the detection result is qualified; and to-be-detected data are extracted to continue to be detected, if the errors are beyond the error range, it indicates that the corrosion condition is severe, the severely corroded part is recorded, and the detection results are recorded by the computer 8.
The above steps are performed repeatedly till all acquired images are detected, and detection is ended.
The aforesaid embodiment and description in the specification are only for explaining the principle of the utility model. Without deviating from the spirit and scope of the utility model, various changes and improvements of the utility model can also be made, and all these changes and improvements should fall within the scope of the utility model claiming for protection. The protection scope of the utility model is defined by the claims attached to the specification and equivalents of the claims.
