Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
The every other embodiment obtained, shall fall within the protection scope of the present invention.
A kind of three-lens rotates oblique photograph measuring system, as shown in Figure 1, including rotating device 10, uses existing skill
Art, the positive camera 20 for being set to 10 bottom of the rotating device and the inclined camera for being set to 10 both sides of the rotating device
30；It is 40 °~45 ° adjustable, the rotations that the central shaft of the inclined camera 30 and the rotating device 10, which is formed by inclination alpha,
Device 10 is for rotating the inclined camera 30.
Wherein, the inclined camera 30 is set as 2, and is symmetrically distributed in the both sides of the positive camera 20.
Specifically, further include the left connecting bracket 40 and right connecting bracket 50 for being symmetrically disposed on the rotating device 10, institute
