Embodiment 1

[0032] see Figure 1~Figure 9 , the three-dimensional binocular camera pan-tilt experimental device, the center of the base 1 is provided with a servo motor 17, the servo motor 17 is connected and drives the turntable 2 to rotate, so as to realize the left and right rotation of the two cameras as a whole, and dynamically capture the moving object; the turntable 2 is connected to the support frame 4, and the support frame is connected to the camera support plate 5 driven by the servo motor 2 for pitching and swinging. When the control command is sent to the servo motor 2 8, the servo motor 2 8 drives the camera support plate 5 to realize two The overall up-and-down pitching action of the camera increases the angle range of the dynamic shooting of the camera; the left and right sides of the camera support plate 5 are respectively installed with two camera supports that are driven by the servo motor 3 13 through the spur rack and pinion mechanism 18 to adjust the distance 9. By c...

Embodiment 2

[0034] This embodiment is basically the same as Embodiment 1, and the features are as follows: a level measuring instrument 3 is provided at the front of the base 1 to detect whether the device is in a horizontal position; each of the four corners of the base 1 is provided with a The horizontal height fine-tuning device 6 is used to adjust the device so that it is in a horizontal position. In the 3D binocular camera shooting experiment, the angle selection of the camera has a great influence on the acquired image feature information. When the camera shoots the same object at different angles, the feature information obtained is quite different. Because some experimental environments are relatively harsh, for example, there is no flat shooting platform, and the tabletop of the experimental table is old and uneven, which will cause the shooting angle of the camera to change, which is likely to cause visual errors of the camera, and the obtained images have a relatively large impa...

Embodiment 3

[0036] Such as Figure 1~Figure 8 As shown, this three-dimensional binocular camera pan-tilt experimental device is an example of real-time adjustment of camera angle and distance. For details, see figure 1 and figure 2 , the level measuring instrument 3 located at the front of the base 1 can detect whether the whole experimental device is in a horizontal position, if not, the level height fine-tuning device 6 located at the four corners of the base 1 can be adjusted for level adjustment. The base turntable 3 located in the central position of the base 1 is as image 3 In the position shown, it is connected to the support frame 4, the controller sends a control command to the servo motor one 17, the servo motor one 17 rotates, and drives the base turntable 3 to rotate left or right, and the left and right cameras on the support frame 4 realize The action of turning left or right as a whole.

[0037] The support frame 4 is connected to the camera support bearing plate 5, the...

Abstract

The invention discloses a three-dimensional binocular camera platform experimental device, which comprising a base, a turntable, a support rack, a camera holder carrying plate, a straight rack and pinion distance adjustment mechanism, two camera holders, two camera turntables, two camera support plates, and five servo motors. A controller sends an instruction to a corresponding servo motor so as to control the above device to adjust the spacing between left and right cameras, the rotation angles of the left and right cameras and the overall pitch angles of the left and right cameras. The device is convenient in operation and strong in practicality.

Description

technical field [0001] The invention relates to a camera shooting experiment device, in particular to a binocular camera pan-tilt experiment device. Background technique [0002] Binocular stereo vision technology is a cutting-edge subject with broad application prospects. With the research and application of modern optics, electronics and computer technology, it will continue to develop and gradually become practical. Key technologies in high-tech fields such as virtual reality can also be applied to aerospace telemetry, military intelligence and reconnaissance and other fields. In foreign countries, binocular stereo vision technology has been widely used in industrial production and residents' life. Binocular stereo vision is called an important branch of computer vision. It is based on the principle of parallax and uses imaging equipment to obtain two images of the measured object from different positions, and obtains the three-dimensional geometric information of the ob...
