Background
The oblique photography equipment generally uses five cameras to carry out aerial survey operation, and takes pictures simultaneously in four directions (45 degrees in each direction) vertically plus front, back, left and right to obtain images on the ground, so that the requirement of three-dimensional automatic modeling is met. The five cameras structure is simple position placement combination, the advantage is stable in structure in the operation process, the fault rate is low, and the shortcoming is because equipment directly constitutes through five cameras, and is with high costs, also makes whole weight overweight because of five cameras simultaneously, and then influences the continuation of the journey of aircraft, has reduced the operating efficiency.
At present, the variant form of five cameras is available, two cameras or three cameras are precisely controlled by using a steering engine, the cameras reach the same shooting angle as the five cameras, and finally the shooting results of the five cameras are simulated. The two-camera and three-camera scheme is essentially generated in order to solve the problems of cost and weight of five cameras, and has the advantages that the number of the cameras is reduced, the price of the product is reduced, the weight is reduced, the load of an aircraft is invisibly reduced, the endurance is improved, and the single operation efficiency is improved. The camera has the advantages that the camera can deflect at an angle through the steering engine, the structure of the 5-camera is simulated, the structure is unstable easily, the vibration of a product is increased, the imaging quality is influenced, the response time of the steering engine is different, the camera cannot be synchronously photographed easily, meanwhile, the rotation precision of the steering engine is reduced gradually due to the fact that the camera is rapidly and repeatedly twisted for a long time, the service life is shortened, faults are increased, the cost of the product in the using process is increased, and therefore when a plurality of operation units purchase equipment, the product with the structure of five traditional cameras is not selected under the condition that the price is different.
Meanwhile, as the requirement of the industry achievement precision is higher and higher, the use of the camera is gradually increased from 2000 ten thousand pixels to 4000 ten thousand pixels, more specifically 1 hundred million pixels, and as the use of the camera is increased, the whole volume and weight are increased, meanwhile, the cost of a single camera is increased from several thousand pixels of 2000 ten thousand levels to several ten thousand elements of 4000 ten thousand levels and several tens of thousand elements of 1 hundred million pixels, and the price of the final product is also higher and higher. Therefore, the current problems are that the price is moderate, so that a user unit is willing to buy the product, and the popularization of the technology causes the profit of the product brought to the user unit to be rapidly reduced. The efficiency of the product is also an important issue, and the current technical 5 camera and other variants are difficult to be compatible at the same time.

As shown in fig. 2 to 3, in the first form, each clockwise rotation of the central shaft 352 by 30 degrees causes the central shaft 361 to rotate by 27 degrees counterclockwise, so as to drive the camera 5 to rotate by 27 degrees clockwise, drive the cameras 6 and 7 to rotate by 30 degrees counterclockwise, and drive the camera 8 to rotate by 30 degrees clockwise. The central shaft 352 rotates 30 degrees counterclockwise at each time to make the central shaft 361 rotate 27 degrees clockwise, so as to drive the camera 5 to rotate 27 degrees counterclockwise transversely, drive the cameras 6 and 7 to rotate 30 degrees clockwise transversely, and drive the camera 8 to rotate 30 degrees counterclockwise transversely. The method for driving the multiple cameras to swing synchronously and repeatedly by circulating the unidirectional power enables the cameras 5, 6, 7 and 8 to have a swing effect to meet the requirements of oblique photography.
As shown in fig. 4 to 5, in the second form, the central shaft 361 rotates 27 degrees clockwise each time to drive the camera 9 to rotate 27 degrees counterclockwise transversely, and the central shaft 451 rotates 30 degrees clockwise each time to drive the camera 9 to rotate 30 degrees clockwise longitudinally.
