Embodiment Construction

[0040] The following will describe specific implementations of the linear camera device according to the present invention with reference to the accompanying drawings. The following detailed description and drawings are used to illustrate the principles of the present invention. The present invention is not limited to the described preferred embodiments, and the protection scope of the present invention is defined by the claims.

[0041] Furthermore, spatially relative terms such as "upper," "lower," "left," and "right," etc., are used to describe the relative positional relationship of one element to another as shown in the drawings. Accordingly, spatially relative terms may be applied in directions other than those shown in the figures when used. Obviously, while all these spatially relative terms refer to the directions shown in the figures for ease of illustration, those skilled in the art will understand that directions other than the directions shown in the figures may b...

Abstract

The invention relates to a line-scan digital camera adjusting device. The device comprises a first support, a second support and an adjuster, wherein the first support is used for installed either a line-scan digital camera or a linear light source, and the second support is used for installing the other one of the line-scan digital camera and the linear light source; the first support is connected to the adjuster, the adjuster can rotate and transversely move the first support and comprises a rotation adjusting component and a transverse movement adjusting component, the rotation adjusting component can drive the first support to rotate, and the transverse movement adjusting component can drive the first support to move transversely; when the line-scan digital camera and the linear light source are installed on the first support and the second support, the longitudinal axis of the line-scan digital camera and the longitudinal axis of the linear light source are located in the same plane. For a linear type photographing device, alignment of the shooting line of the line-scan digital camera and light of the linear light source is achieved through the adjuster, the alignment process is simple, the alignment speed is high, and the alignment precision is high.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to line array camera adjustment equipment. Background technique [0002] During the operation of the subway network, if there are hidden dangers in the tunnel structure and surrounding rock and soil, the tunnel will be subjected to the load and vibration of the subway train, and the tunnel structure will be deformed and cracked, which will affect the safety of the subway operation. [0003] Therefore, in the process of subway tunnel acceptance and operation, the detection of tunnel surface cracks is very important. Manual measurement is a commonly used method in tunnel inspection technology at present. Manual measurement has low efficiency, poor reliability, and is easy to miss inspection. The judgment of crack level mainly depends on experience. Moreover, for the subway network of hundreds of kilometers to several thousand kilometers, it is impossible to rely on manual...
