It lays four shooting devices in aircraft fuselage bottom including being the field font, taking the device and including a magazine, the magazine top links to each other with a looks body, be equipped with respectively in the looks body one with magazine top parallel arrangement's imaging sensor and shutter, the magazine bottom be equipped with one with the camera lens of perpendicular settings of imaging sensor, the device is taken by every group, and all fixed link to each other and every magazine bottom all keeps at same horizontal plane through the magazine lateral wall, it is continuous with controlling means that the shutter of every group shooting device passes through the wire respectively. It reduces aerial photogrametry's cost, and the camera can reach the pixel that accords with aerial photogrametry and require equally using CCD and CMOS sensor formation of image back, and it is wide that the area is covered to the aviation image, and the boat is taken the photograph efficiently, and it is high to become the picture precision, has solved the problem that exists among the prior art.
Description
Technical field:
The utility model relates to a kind of specialized equipment used when manned machine and unmanned plane carry out photogrammetric measurement work, especially a kind of photogrammetric measurement big area array digital camera device.
Background technology:
Photogrammetric measurement is one of method of survey field, working method carries out regular shooting to ground aloft by manned machine or UAV flight's optical camera, then obtained single photo is carried out post-processed, as the geographic information data manufacturing topomap, and aerial photographic camera is aerophotogrammetric infrastructure device.Present stage, manned machine generally adopts the large-scale digital camera of import, and imaging pixel is between 1-2 hundred million pixel, but this type of camera price is between 800-1000 ten thousand, and price costly, substantially increases aerophotogrammetric cost; And unmanned plane generally adopts finished product civil camera, imaging pixel is between 3000-8000 ten thousand pixel, though this type of camera cost is low, but CCD and cmos sensor area too small, make individual aviation image contain area little, measure baseline (distances between adjacent two main picture points of photo) short, cause boat to take the photograph efficiency low, cost of manufacture is high, mapping precision low (baseline is short), thus limit aerophotogrammetric development, become the aerophotogrammetric technical bottleneck of restriction.
Utility model content:
The utility model provides a kind of photogrammetric measurement big area array digital camera device, its structure is simple, reduce aerophotogrammetric cost, camera is after use CCD and cmos sensor imaging, can reach the pixel meeting photogrammetric measurement and require equally, it is wide that aviation image contains area, and it is high that boat takes the photograph efficiency, mapping precision is high, solves problems of the prior art.
The utility model for solving the problems of the technologies described above adopted technical scheme is:
A kind of photogrammetric measurement big area array digital camera device, comprise four filming apparatus be laid in matrix pattern bottom airframe, described filming apparatus comprises a magazine, magazine top is connected with a phase body, the imaging sensor be arranged in parallel with magazine top and a shutter is respectively equipped with in phase body, one and the vertically disposed camera lens of imaging sensor is provided with bottom magazine, often organize filming apparatus be all fixedly linked by magazine sidewall and all remain on same level bottom each magazine, the shutter often organizing filming apparatus is connected with control device respectively by wire.
Described camera lens is tight shot.
Each camera lens be arranged on bottom magazine is separately positioned on one jiao of the matrix pattern center formed near four filming apparatus, and adjacent two camera lenses are symmetrical arranged.
The utility model adopts such scheme, and structure is simple, reduces aerophotogrammetric cost, camera is after use CCD and cmos sensor imaging, and can reach the pixel meeting photogrammetric measurement and require equally, it is wide that aviation image contains area, it is high that boat takes the photograph efficiency, and mapping precision is high.

Embodiment:
For clearly demonstrating the technical characterstic of this programme, below by embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.
As Figure 1-4, a kind of photogrammetric measurement big area array digital camera device, comprise four filming apparatus be laid in matrix pattern bottom airframe, described filming apparatus comprises a magazine 1, magazine 1 top is connected with a phase body 2, an imaging sensor be arranged in parallel with magazine 1 top 3 and shutter 4 is respectively equipped with in phase body 2, a camera lens 5 arranged with imaging sensor 3 central vertical is provided with bottom magazine 1, often organize filming apparatus be all fixedly linked by magazine 1 sidewall and all remain on same level bottom each magazine 1, the shutter 4 often organizing filming apparatus is connected with control device respectively by wire.
Described camera lens is tight shot.Select field angle can cover the camera lens of four imaging sensors simultaneously.
Each camera lens 5 be arranged on bottom magazine 1 is separately positioned on one jiao of the matrix pattern center formed near four filming apparatus, and adjacent two camera lenses 5 are symmetrical arranged.Making four photos simultaneously taken have unified main picture point when splicing, facilitating the later stage to use software to process, being convenient to the overlay region in photo can be carried out mate, correct and split, substantially increasing the precision of image.
Before using, by this device fuselage 2 upwards, camera lens 5 is fixedly mounted on the bottom of airframe downwards, adjust each camera lens 5 and be vertically set on below imaging sensor 3 respectively, by interior orientation method, camera calibration is not carried out to the phase status often organized in filming apparatus.When aircraft flight needs photogrammetric measurement to correct position, the shutter 4 controlling often to organize same model on filming apparatus by control device exposes simultaneously, image projection stores on the imaging sensor 3 by camera lens 5, often organize filming apparatus gained image and all have overlapped part, later stage carries out resampling to overlapping region, determine to connect rectangle position in splicing image, automatically splicing image overlap part is cut, export camera unit wide cut image, greatly reduce aerophotogrammetric cost, camera is after use CCD and cmos sensor imaging, the pixel meeting photogrammetric measurement and require can be reached equally, it is wide that aviation image contains area, it is high that boat takes the photograph efficiency, mapping precision is high.
Above-mentioned embodiment can not as the restriction to the utility model protection domain, and for those skilled in the art, any alternate modification make the utility model embodiment or conversion all drop in protection domain of the present utility model.
The utility model does not describe part in detail, is the known technology of those skilled in the art of the present technique.
