Example Embodiment

[0024] Example

[0025] Figure 1-4 It is shown that a specific embodiment of the present invention is an imaging device for a large geotechnical centrifuge, which is composed of a camera holder 27 fixed on the outside of the model box 26 of the centrifuge, and on the outside of the camera holder 27 A two-dimensional mobile device that can move horizontally and vertically is fixed vertically. The camera 18 is fixed on the two-dimensional mobile device, and the lens direction of the camera 18 faces the model box 26. The two-dimensional mobile device and the camera 18 are both integrated with data control and processing. The device is electrically connected.

[0026] The specific structure of the two-dimensional mobile device in this example is:

[0027] The camera 18 is fixed on the camera mount 17, the lens of the camera 18 fits into the hole of the grating mount 19 on the camera mount 17, the back of the camera mount 17 (that is, the side of the camera mount away from the camera l...

Abstract

The invention discloses an imaging device of a large geotechnical centrifuge, which comprises a camera bracket 27, a two-dimensional moving device, a camera 18, a model casing 26 and a data control and processing device, wherein the camera bracket 27 is fixed outside the model casing 26 of the centrifuge; the two-dimensional moving device which can transversely and vertically move is vertically fixed on an outside frame of the camera bracket 27; the camera 18 is fixed on the two-dimensional moving device, and a lens of the camera 18 is toward the model casing 26; and the two-dimensional moving device and the camera are both electrically connected with the data control and processing device. The device can shoot over against any point of a model, has high definition of images, low cost and easy implementation and can more favorably analyze the model.

Description

technical field [0001] The invention relates to an imaging device of a large geotechnical centrifuge. Background technique [0002] The large geotechnical centrifuge consists of a rotating arm, a column connected to the rotating arm, a model box at one end of the rotating arm, a counterweight box at the other end, and a drive and control system. During operation, the supporting imaging system takes pictures of the geotechnical model inside the high-speed rotating model box to obtain the dynamic change process of the geotechnical model under the state of centrifugal force. The existing imaging system, one is installed on the roof of the centrifuge room, the camera has a long distance to take photos, and there is high-speed relative motion with the geotechnical model to be photographed, resulting in blurred photos and difficult to focus accurately. The second is to adopt a plurality of cameras closely arranged in an array and arranged on the fixed bracket of the model box. Al...
