Example Embodiment
[0020] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail in conjunction with specific embodiments and with reference to the accompanying drawings.
[0021] The invention provides a device and method for remotely accurately measuring the vertical displacement of a foundation, such as figure 1 As shown, the device includes a laser light source, a first reflecting mirror, a second reflecting mirror, a focusing lens and a CCD in sequence along the optical path, among which:
[0022] The first reflecting mirror and the second reflecting mirror are 45° reflecting mirrors. The first reflecting mirror receives the horizontal light emitted by the laser light source, and changes the horizontal light 90° clockwise on the horizontal plane and reflects it to the second reflecting mirror , The second reflector changes the horizontal light by 90° in the clockwise direction on the ho...
