Problems solved by technology

[0006] The bracket uses two cameras to shoot, and the angle between the cameras is controlled by the control device to change the shooting angle. However, the shooting range of its single-direction rotation is limited, the repetition rate is low, and the data collection is incomplete. It is difficult to obtain in the later three-dimensional modeling full 3D image

Embodiment 1

[0032] combine figure 1 , a kind of multi-angle oblique photography device based on unmanned aerial vehicle of the present embodiment, comprises unmanned aerial vehicle body 11 and the stabilized platform 12 that is arranged on the bottom of unmanned aerial vehicle 11, also includes aerial photography platform and aerial survey unit, described aerial survey The center of the unit 4 is symmetrically provided with a support plate 41 and a camera 42, the camera 42 is installed on the outer end of the support plate 41, and the shooting angle between the two cameras 42 is 35-70°; On the cloud platform 12, the aerial photography platform is used to drive the aerial survey unit 4 to rotate in the vertical plane and the horizontal plane.

[0033] One end of the support plate 41 is connected with the steering gear, and the other end is installed with the camera 42 , that is, the outer end of the support plate 41 is connected with the camera 42 . The support plate 41 is mainly used for...

Embodiment 2

[0041] combine figure 1 and figure 2 , a kind of multi-angle oblique photography device based on unmanned aerial vehicle of the present embodiment, its basic structure is identical with embodiment 1, and its difference is: in the present embodiment, the bracket of the stabilized platform 12 is fixed on unmanned by bolt On the body 11 , the first steering gear 2 is provided with a supporting base, through which the first steering gear 2 is connected with the stabilization platform 12 . The aerial photography platform includes a first steering gear 2 and a second steering gear 32 connected through an intermediate carrier 31 , and the rotation axis of the second steering gear 32 is connected with the aerial survey unit 4 .

[0042] The first steering gear 2 can be installed vertically, and its rotating shaft can rotate in the 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 ...

Embodiment 3

[0045] A kind of multi-angle oblique photography device based on unmanned aerial vehicle of the present embodiment, its basic structure is identical with embodiment 2, and its difference is: the first steering gear 2 is used to drive the intermediate carrier 31 and the second steering gear 32 in Rotate 360° in the horizontal plane, and control it to rotate 90° each time, then the target object can be photographed and collected from 4 directions.

[0046] The second steering gear 32 controls the aerial survey unit 4 to have two kinds of shooting attitudes. During the first attitude, the inclination angles of the two cameras 42 are the same, as image 3 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 direction of the two cameras 42 and the vertical direction is 30°.

[0047] After the rotating shaft of the second steering gear 32 rotates, it presents a second posture, such as Figure 4 As ...

Abstract

The invention discloses a UAV-based multi-angle oblique photographing device and belongs to the field of UAVs. The UAV-based multi-angle oblique photographing device comprises an UAV body, a stabilizing holder disposed at the bottom of the UAV body, an aerial photographing holder and an aerial survey unit, wherein the aerial survey unit is provided with a support plate and cameras which are centrally symmetric. The camera is mounted on the outer end of the support plate and a photographing intersection angle between the two cameras is 35 to 70 degrees. The aerial photographing holder is mounted on the stabilizing holder and is used for driving the aerial survey unit to rotate in vertical and horizontal planes. The UAV-based multi-angle oblique photographing device uses the double cameras so as to be greatly reduced in weight and improved in endurance capability, and can achieve a high photographing repetition rate and ensure the accuracy of three-dimensional modeling.

Description

technical field [0001] The present invention relates to the technical field of unmanned aerial vehicles, and more specifically, relates to a multi-angle oblique photography device based on unmanned aerial vehicles. Background technique [0002] In recent years, the field of international geographic information has combined traditional aerial photography technology and digital ground acquisition technology to develop a high-tech called airborne multi-angle oblique photography, referred to as oblique photography technology. Tilt photography technology collects ground images from multiple angles simultaneously by carrying multiple or multiple sensors on the same flight platform, thereby overcoming the limitation of traditional aerial photography technology that can only shoot from vertical angles, and can more truly reflect the ground The actual situation of the object makes up for the deficiency of the orthophoto, and realizes the 3D modeling technology based on image dense ma...
