Abstract
Description
Technical Field
[0001] This application relates to the technical field of surveying and mapping devices, and more particularly, to a laser surveying and mapping device. Background Art
[0002] More and more R & D teams integrate surveying and mapping cameras inside the device housing of lidar to facilitate accurate surveying and mapping by lidar. The surveying and mapping camera is equipped with a mechanical camera shutter, which has a service life and needs to be replaced about once a year under normal use. When replacing the camera shutter in the prior art, the outer shell needs to be removed. If directly exposed to an environment with low cleanliness, it will cause damage to the internal optical path of the laser surveying and mapping device. Therefore, users usually return the device to the factory, and the original factory replaces the camera shutter in a clean room. This not only takes too long but also has a high maintenance cost. Since the prior art requires the entire outer shell of the device to be disassembled, the internal components of the device will be exposed, which is likely to cause damage to precision devices. Therefore, even when operating in a dust-free environment, the risk is relatively high. Summary of the Utility Model

[0030] More and more R & D teams integrate mapping cameras inside the device housing 100 to facilitate precise mapping. The mapping camera is equipped with a mechanical camera shutter 105, which has a service life and needs to be replaced after about one year of normal use. When replacing the camera shutter 105 in the prior art, the outer shell needs to be removed. If directly exposed to an environment with a low cleanliness level, it will cause damage to the internal optical path of the laser mapping device. Therefore, users usually return the device to the original factory, and the original factory replaces the camera shutter 105 in a clean room. This not only takes too long but also has a relatively high maintenance cost. Since the prior art requires the entire outer shell of the machine to be disassembled, the internal components of the device will be exposed, which is likely to cause damage to precision devices. Therefore, even when operating in a dust-free environment, the risk is relatively high.

A camera shutter 105 inserted into the mapping camera body 101 is provided inside the shutter seal chamber 103. The camera shutter 105 can pass through the window 104 from the shutter seal chamber 103 along a direction perpendicular to the main optical axis of the mapping camera body 101.
[0033] It should be noted that the shutter seal chamber 103 is disposed on one side of the main optical axis. The mounting surface where the camera shutter 105 is located is perpendicular to the main optical axis of the mapping camera body 101, and the camera shutter 105 can enter the shutter seal chamber 103 along a direction perpendicular to the main optical axis of the mapping camera body 101 and be inserted onto the camera lens of the mapping camera body 101.
[0034] When the camera shutter 105 reaches its service life, the user can take out the camera shutter 105 to be replaced from the shutter seal chamber 103 through the window 104 and then install a new camera shutter 105.

In addition, compared with the prior art, in the embodiment of the present application, the camera shutter 105 is replaced through the window 104 without disassembling the device housing 100, so the operation risk of disassembling and assembling the camera shutter 105 can be reduced, enabling the user to quickly and safely replace the camera shutter 105 at the mapping site.
