[0046] More specifically, the vertical angle adjustment component 102 includes:

[0047] The second housing 1021 is located at the output position of the horizontal angle adjustment component 101. A pair of opposite sidewalls of the second housing 1021 are provided with opposite second through holes. A horizontal second rotating shaft 1022 is rotatably connected to the two second through holes. Both ends of the second rotating shaft 1022 are located outside the second housing 1021. Both ends of the second rotating shaft 1022 are hinged to a hinge seat 1023. The portion of the second rotating shaft 1022 located inside the second housing 1021 is coaxially provided with a driven pulley 1024.

[0051] The first motor 1015 driver module and the second motor 1025 driver module can be DM542 driver modules.

[0052] Specifically, the visual image displacement meter body 2 includes:

[0055] The electric focusing module 203 is quite common in the prior art and will not be described in detail here.

[0056] In the above embodiment, the first motor 1015 driver module is used to receive the orientation adjustment command from the remote controller 3, and adjust the rotation of the first motor 1015 according to the orientation adjustment command, so that the visual image displacement meter body 2 rotates to the orientation required by the construction personnel.

[0057] In the above embodiment, the second motor 1025 driver module is used to receive the elevation angle adjustment command from the remote controller 3, and adjust the rotation of the second motor 1025 according to the elevation angle adjustment command, so that the visual image displacement meter body 2 rotates to the elevation angle required by the construction personnel.

[0059] The above embodiment is used as follows: Targets are placed on the construction structure that needs to be monitored for displacement. Since there are many monitoring points, multiple targets are placed on each monitoring point of the construction structure. The visual image displacement meter is then installed at a certain distance from the construction structure. The first motor 1015 and the second motor 1025 are controlled by the remote controller 3 to rotate the visual image displacement meter body 2 on the electric pan-tilt head 1 to the orientation and elevation angle required by the construction personnel. At this time, the visual image displacement meter body 2 is basically aligned with one of the targets. Then, the electric focusing module 203 is controlled by the remote controller 3 to focus the lens 204 on the target, thereby realizing the monitoring of the target.

[0060] To switch the target being monitored by the visual image displacement meter, the remote controller 3 controls the first motor 1015, the second motor 1025, and the electric focusing module 203 to focus the visual image displacement meter on another target that needs to be monitored.

[0061] As can be seen from the above embodiments, the visual image displacement meter is equipped with a driver module that communicates with the remote controller 3, and also with an electric focusing module 203 that communicates with the remote controller 3. Therefore, the electric pan-tilt head 1 and the electric focusing module 203 of the visual image displacement meter can be controlled by the remote controller 3. When the visual image displacement meter is configured with multiple targets, the visual image displacement meter can be focused on different targets by controlling the electric pan-tilt head 1 and the electric focusing module 203. At the same time, after the visual image displacement meter is installed, the construction personnel can also use the remote controller 3 to debug the visual image displacement meter without having to climb to the installation location of the visual image displacement meter for close-range debugging, thus reducing the safety risks of construction.
