Description
Technical field
The present invention relates to a kind of photogrammetric apparatus, particularly relate to a kind of sweep type low altitude photogrammetry device based on small-sized unmanned plane.
Background technology
At present, the low altitude photogrammetry device researched and developed both at home and abroad is concentrated mainly on the oblique photograph that vertical photography based on one camera is measured and polyphaser combines and measures.The atural object image information that cannot obtain multi-angle measured by the vertical photography of one camera, and the side-information of such as building, intersection angle is little, constrains the raising of photogrammetric accuracy.And the oblique photograph measuring table structure of polyphaser combination is complicated, camera number is more, and cost is high, and the activity duration is short, has a certain distance with the present invention on the activity duration.Multi-angle photogrammetric is mainly used in the high-precision photogrammetric application such as with three-dimension tidal current.
Existing small-sized unmanned plane multi-angle aerophotogrammetry is concentrated mainly on oblique photograph and measures the realization of system, a kind of numeral aviation oblique photograph measurement apparatus that have China 2013 year authorize close with the research contents of the present invention, the patent No.: ZL201220681352.4, describe a kind of numeral aviation oblique photograph measurement apparatus, this device is installed a lens axis vertically downward lower and is installed on support depending on camera and four inclined camera hoops, its lens axis is a fixed angle with the lower lens axis regarding camera in space, and it is respectively directed to four direction, constitute all around and regard down the vertical/oblique photograph structure of five shooting angle, to realize the function of multi-angled shooting.The Aviation Digital oblique photograph measurement apparatus of utility model patent multi-angle array combination in 2015, the patent No.: ZL201510002994.5, describe the Aviation Digital oblique photograph measurement apparatus of a kind of multi-angle array combination, including photographing unit multi-angle array element, and the camera control unit being connected with this photographing unit multi-angle array element, image store unit, power control unit, multiple photograph unit is included at photographing unit multi-angle array element, each photograph unit includes multiple stage photographing unit, combine a photographing unit in each photograph unit and constitute a shooting array combination, boat can be extended and take the photograph ken angle, improve the quality of outdoor scene threedimensional model.Patent of invention many rotor wing unmanned aerial vehicles oblique photograph system that 2016 authorize, the patent No.: ZL201510668233.3, describe a kind of many rotor wing unmanned aerial vehicles oblique photograph system, including The Cloud Terrace carry assembly, oblique photograph The Cloud Terrace, including roll axle carry, upper backup pad, lower bracing frame, lower bracing frame carry framework, four sides of lower bracing frame arrange inclination installing rack, and photographic attachment is fixedly mounted on inclination installing rack, realizes oblique photograph by polyphaser combination and measures.
Summary of the invention
It is an object of the invention to provide a kind of sweep type low altitude photogrammetry device based on small-sized unmanned plane, concentrate on polyphaser combination oblique photograph measurement apparatus and there is the shortcomings such as structure is complicated, The Cloud Terrace volume is big, device is heavier, camera angle is fixed, camera quantity is many, expensive, the activity duration is short solving existing multi-angle low altitude photogrammetry.Though system is measured in the combination oblique photograph of above-mentioned polyphaser can realize multi-angle earth observation, but needs the camera of up to more than four to shoot simultaneously, image can only be gathered according to support fixed angle.Existing for multi-angle low altitude photogrammetry depend on increase camera quantity complete, the most simple shoots with fixing several angles, and small-sized unmanned aerial vehicle platform is easily affected by air-flow or wind-force, the image that this type of platform obtains is difficult to ensure that prescription, simultaneously, polyphaser combination is added significantly to small-sized unmanned plane weight, and then greatly reduces the stagnant idle job time, affects low altitude photogrammetry efficiency.
The present invention is realized in, it includes shock-absorbing ball, gripper shoe, drive motor, little gear, gear wheel, rocking arm, hanger bar, camera pedestal gripper shoe, roller, Airborne Camera, small-sized unmanned plane, it is characterized in that: the lower central plate of small-sized unmanned plane connects gripper shoe by shock-absorbing ball and forms damped platform, damped platform center vertically connects hanger bar, the upper end of hanger bar fixing connection drives motor, motors is driven to connect little gear, the engagement of little gear connects gear wheel, one end of connecting rocker arm on gear wheel, the other end of rocking arm connects one end of camera pedestal gripper shoe by roller, the bottom Vertical movements of described hanger bar connects the center of camera pedestal gripper shoe, it is connected with Airborne Camera in described camera pedestal gripper shoe.
Described driving motor and Airborne Camera connect lithium battery and the main control unit of small-sized unmanned plane.
The solution have the advantages that: complete multi-angle low altitude photogrammetry based on sweep type photographic imagery, only rely on separate unit digital camera and during small-sized unmanned plane is advanced, swing shooting to obtain several images in certain angle.Compared with other above-mentioned inventions, it first it is that shooting angle is not fixed, it is possible to provide continuous print image in vertical photography to certain angle of inclination；Secondly, simplify the structure of current main-stream oblique photograph measurement apparatus, alleviate installation weight, add the activity duration, and angle shot is little by wind-force restriction continuously, plant maintenance easily and reduces the threshold that the oblique photograph of multi-angle low latitude is measured, and this device performance is stable, cost is cheaper.This aerial device shoots over the ground with on-fixed angle, imaging in the way of sweeping, angle continually varying aerial images in certain angle can be obtained, wide baseline high inclination-angle, the stereogram of high degree of overlapping can be collected, advantageously ensure that photographic image quality and improve small-sized unmanned plane mapping precision；Meanwhile, present configuration is simple, lighter weight, low cost, data acquisition modes idle job time flexible, stagnant length, working performance are high.
