Description
Technical field
The present invention relates to automation field, refer to especially a kind of multidimensional image harvester.
Background technology
Tower crane is that a kind of hoisting equipment the most frequently used on construction site has another name called derrick crane, with a section spreading, is used for hanging the raw material of the constructions such as working reinforcing bar, wood are stupefied, concrete, steel pipe.
By having or not walking mechanism can be divided into portable tower tower crane and fixed type tower crane.
Portable tower tower crane can be divided into again four kinds of rail mounteds, rubber-tyred, truck mounted, crawler type according to the difference of running gear.The tower tower crane tower body of rail mounted is fixed on walking underframe, can on ad hoc track, move, and good stability, can walk by on-load, and operating efficiency is high, thereby is widely used in building installation engineering.The tower tower crane rail-free of rubber-tyred, truck mounted and crawler type device, conveniently moving, but can not on-load walking, less stable.
Fixed tower tower crane is according to the difference of installation position, is divided into again and adheres to two kinds of jack up and inner climbing types, adheres to from rising tower tower crane and can raise with building, be applicable to skyscraper, the horizontal load being transmitted by tower crane is only born in building structure, convenient attachment, but it is many to take structural steel; Inner climbing crane tower, at interior of building (elevator, staircase), climbs by a set of bracket and elevator system, and jacking is more loaded down with trivial details, but it is few to take structural steel, does not need installing basis, and all deadweight and load are born by building.
No matter be movable tower crane or fixed type tower crane, all need operating personnel voluntarily or by elevator, arrive between the control at top and operate, stand the operational environment of high temperature and heating summer or low temperature severe cold, and tower crane is higher, danger coefficient is also higher, and tower crane accident also happens occasionally, therefore, how realizing the Long-distance Control of high-order tower crane, is current problem demanding prompt solution.
Summary of the invention
The present invention proposes a kind of multidimensional image harvester, has realized the remote image collection to high-order tower crane.
Technical scheme of the present invention is achieved in that
A multidimensional image harvester, comprising:
Camera, its quantity is a plurality of, at least comprises the second camera and the 3rd camera that are arranged on the first camera of the long-armed top of tower crane downside and are arranged on the control desk left and right sides, high-altitude;
Image capture module, comprises the sampling switch that is arranged on input, with frequency cyclic switching between described camera of 50Hz; Coding module, encodes to the camera being switched to, with sampled images compression packing synchronous driving;
Image processing module, receives the compressed package of described image capture module output, and arrives corresponding output channel according to coding and decoding;
Display apparatus module, its quantity is identical with described camera quantity, is connected to the passage of image processing module, and shows the image of the camera collection that this passage is corresponding.
Alternatively, the quantity of described display is at least three, the first display shows the tower crane forearm image of the first camera collection, second display shows the high-altitude control desk left-side images that second camera gathers, the 3rd display shows the high-altitude control desk image right of the 3rd camera collection, the first display is placed between two parties, and second display and the 3rd display are placed on respectively position, left and right.
Alternatively, described image processing module is dsp processor.
Alternatively, described image processing module is TMS320F2812 dsp processor.
The invention has the beneficial effects as follows:
(1) multidimensional image of realizing job site by being arranged on the camera of a plurality of positions gathers, and realizes scene and reduce in real time on a plurality of display screens;
(2) by sampling switch to a plurality of camera circulating samplings, then circulation sends to image processing module, image processing module, by image transcoding send to corresponding display respectively, has been saved the quantity of image processing module, has also saved cost.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the control block diagram of multidimensional image harvester of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, multidimensional image harvester of the present invention comprises: camera, its quantity is a plurality of, at least comprises the second camera 11 and the 3rd camera 12 that are arranged on the first camera 10 of the long-armed top of tower crane downside and are arranged on the control desk left and right sides, high-altitude.
Image capture module 20, comprises the sampling switch that is arranged on input, with frequency cyclic switching between described camera of 50Hz; Coding module, encodes to the camera being switched to, with sampled images compression packing synchronous driving.
Image processing module 30, receives the compressed package of described image capture module 20 outputs, and arrives corresponding output channel according to coding and decoding.Preferably, described image processing module is dsp processor.
