Example Embodiment
[0033] Example 1
[0034] Combine figure 1 The multi-angle dual-camera tilt photography device of this embodiment is mainly composed of an aerial camera platform and an aerial survey unit. In this embodiment, the aerial survey unit 4 is centrally symmetrically provided with a support plate 41 and a camera 42, and the camera 42 is installed on the support plate 41. At the outer end, the shooting angle between the two cameras 42 is 35-70°.
[0035] One end of the support plate 41 is connected with the steering gear, and the other end is installed with a camera 42, that is, the outer end of the support plate 41 is connected with the camera 42. The supporting plate 41 is mainly used to connect the camera, and is not limited to a plate shape, and may be a block shape or a rod shape. In this embodiment, it is preferably a plate shape.
[0036] The installed camera 42 is used for collecting data, and the collected data is used for three-dimensional modeling. Therefore, it is necessary to c...
Example Embodiment
[0040] Example 2
[0041] The improvement of this embodiment is that the aerial photography pan / tilt includes a first steering gear 2 and a second steering gear 32 connected by an intermediate carrier 31, and the rotation axis of the second steering gear 32 is connected to the aerial survey unit 4.
[0042] The first steering gear 2 can be installed vertically, and its rotating shaft can rotate in a horizontal plane. The upper end of the intermediate carrier 31 is connected with the rotating shaft of the first steering gear 2, and the second steering gear 32 is installed at its lower end for controlling the second rudder. The machine 32 rotates in a horizontal plane.
[0043] The rotation of the first steering gear 2 can only make the camera take pictures from different orientations, and the tilt angle does not change. The second steering gear 32 can control the aerial survey unit 4 to rotate in the vertical plane so that the camera is positioned in the vertical direction to take pic...
Example Embodiment
[0044] Example 3
[0045] The improvement of this embodiment is that the first steering gear 2 is used to drive the intermediate carrier 31 and the second steering gear 32 to rotate 360° in the horizontal plane, and each time they rotate 90°, the target object can be controlled from 4 directions. Shooting data collection.
[0046] The second steering gear 32 controls the aerial survey unit 4 to have two shooting attitudes. In the first attitude, the tilt angles of the two cameras 42 are the same, such as figure 2 As shown, the shooting angle between the two cameras 42 in the aerial survey unit 4 is limited to 60°, and the angle between the shooting directions of the two cameras 42 and the vertical direction is 30°.
[0047] The shaft of the second steering gear 32 rotates and assumes the second posture, such as image 3 As shown, one of the cameras 42 is located in the vertical shooting position, and the angle between the other camera and the vertical direction is 60°.
