Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
A kind of ship overload image detection device, comprises and detects boats and ships 1.
Be provided with two video cameras 2 at the stem place detecting boats and ships 1, be all arranged on the highest point on stem deck, two video cameras 2 are all connected to video server 3 by RS485 bus, and the output of video server 3 is connected to switch 4.The output of switch 4 connects the input of video frame fetching device 5, and the output of video frame fetching device 5 connects the input of microcomputer 6.
Microcomputer 6 is 51 series monolithics or arm processor or industrial computer.Microcomputer 6 is also connected with large-screen display equipment 14, acoustic-optic alarm 15, man-machine interface 16 and radio transmission apparatus 17.
Each video camera 2 be also provided with protective cover 7 camera lens 11 is outer, protective cover 7 comprises transparent cover portion 8 and is connected to the installing ring 9 in cover portion 8, cover portion 8 can cover the cover portion 8 of described video camera 2 camera lens 11, cover portion 8 makes for stealthy rain brush sight glass, be protruding hollow ball-shape globoidal structure, installing ring 9 is the installing ring 9 that rigid plastics or stainless steel are made.
Be provided with the mount pad 10 for connecting protective cover 7 around the camera lens 11 of video camera 2, installing ring 9 is identical with size with the shape of mount pad 10, and installing ring 9 is connected to mount pad 10 by screw 13.Waterproof washer 12 is also provided with between installing ring 9 and mount pad 10.
By said structure, protective cover 7 and mount pad 10 are tightly connected.Protective cover 7 can protection against the tide, waterproof, damp proof, adopts stealthy rain brush sight glass protective cover 7, and stealthy rain brush sight glass has and repels water, dust, removes the function such as fog and condensation frost, can solve the adverse effect that work under bad environment is brought very well.
The working method of this ship overload image detection device is: two high definition focal length video cameras 2 are arranged on the stem that maritime affairs detect boats and ships 1, dynamically the water line video information of shooting boats and ships 1 to be detected.
Video camera 2 is connected to the analog video input interface of video server 3; Video server 3 compresses the video information received, store and processes, and video server 3 adopts M-JPEG or MPEG-2 compressed format, carries out compressed encoding when meeting technical indicator to video data, with the requirement of satisfied storage and transmission
Switch 4 concentrates on one piece the video information of multiple stage high definition focal length video camera 2, manages all vision signals concentratedly, and video frame fetching device 5 carries out two field picture extraction to the water line video information obtained.
Two field picture imports microcomputer 6 into, and microcomputer 6 processes two field picture according to certain image processing algorithm, determines the accurate draft amount of boats and ships 1 to be detected, and by result and computer-internal stored in java standard library comparing.When the loading capacity of target boats and ships is greater than the dead weight of respective model in database, can judge that boats and ships 1 to be detected are in overload condition, at this moment microcomputer 6 connects audible-visual annunciator, sends sound and light alarm signal, otherwise, then do not produce alarm signal.
Because the water surface can produce random scatters light under daylight and other strong illuminations, utilize video frame fetching device 5 that boats and ships 1 to be detected can be improved accuracy of detection by cutting the method extraction two field picture getting frame separately from dynamic video, and at utmost shield the interference of external context.
The information such as dead weight exporting respective model boats and ships in the model of boats and ships 1 to be detected, real draft amount, database to microcomputer 6 by man-machine interface 16.User's viewing terminal display device intuitively can see whether boats and ships 1 to be detected overload.When ship overload, audible-visual annunciator can send alarm signal and voice message.Testing result is passed through the Surveillance center of radio transmission apparatus 17 real-time Transmission to marine board by microcomputer 6.
This device can also add at any time and upgrade database data, adds newly-increased ship draught data in time draft amount database, the coverage rate of detection can be made to increase, greatly improve the accuracy that ship overload detects according to the development of shipbuilding industry.
This device solve Traditional Man measure efficiency low, not comprehensively, the problem of poor accuracy, also compensate for the limitation that inland navigation craft fixed point detects.Realize Remote Dynamic to detect flexibly.Improve the flexibility that ship overload detects.Adopt two or more high definition focal length video cameras 2, ensure that the water line information of boats and ships 1 to be detected can long-rangely obtain quickly and accurately.Stealthy rain brush sight glass protective cover 7 installed by the camera lens 11 of high definition focal length video camera 2, can protection against the tide, waterproof, antifog, thus ensures that package unit normally works in the aquatic environment of bad environments.Terminal presentation facility can visual display detecting result, and visualization is high.The utility model has automatically, efficiently, accurately detect the feature that whether overloads of boats and ships 1.Radio transmission apparatus 17 real-time Transmission to the Surveillance center of marine board, thus realizes ship overload remote monitoring, improves monitoring efficiency, and facilitates marine board to carry out record backup to monitored results.
Can also be that microcomputer 6 internal database adds data in practice, add newly-increased ship draught data in time draft amount database according to the development of shipbuilding industry, the coverage rate of detection can be made to increase, greatly improve usability and the accuracy of detection of this ship overload image detection device.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection range that all should belong to the utility model claims.The part be not described in detail in this specification belongs to the known prior art of professional and technical personnel in the field.
