Description

Technical Field

[0001] The utility model belongs to the technical field of road surveying and mapping, in particular to a liftable vehicle-mounted camera. Background Art

[0002] In road surveying and mapping, vehicle-mounted cameras play an important role. By capturing images and videos on the road, vehicle-mounted cameras provide surveyors with real-time road information, making road surveying and mapping work more efficient and accurate.

[0003] Among them, after searching, it was found that there is a patent number of CN202021749822.7, which discloses a road map acquisition device and a lane line map mapping system, including a GNSS antenna, a GNSS / INS combined navigation device, a laser radar device and an installation platform, which does not change the original structure of the motor vehicle, only uses the existing roof rack of the motor vehicle, and the device is portable and fixed on the roof of the motor vehicle through multiple detachable connection structures. Further, the outer size of the frame base is close to a square, and the installation is stable, avoiding the problem of tilting caused by insufficient stiffness of the side rod in a certain direction, etc. The support rod and the mounting rod of the mounting frame for installing the laser radar device are connected by a universal adjustment structure, and the universal angle adjustment can meet the installation and use of different motor vehicles. For example, the rear size specifications of different models are different, and the installation angle of the laser radar device can be adaptively adjusted according to different motor vehicles; further, the universal angle adjustment can be biased for the key scanning area. For example, when it is necessary to scan the printed matter in the guide channel on the right side of the road (according to traffic regulations, vehicles are prohibited from entering the guide channel), the universal mechanism can be adjusted to the right. Furthermore, the support rod and / or the mounting rod is configured as a retractable structural rod. When the installation angle reaches the adjustment limit, the position of the laser radar device can be adjusted by extending the support rod and / or the mounting rod. In this way, the universal adjustment connection structure and the support rod and / or the mounting rod can be adjusted in coordination, which can meet the use of most motor vehicles. The GNSS antenna, GNSS / INS combined navigation equipment, laser radar equipment and the mounting platform are all configured to be detachably connected, which is convenient for maintenance and replacement. For example, if one or more equipment failures are found during the test, they can be replaced in time. The laser radar equipment mounting frame uses a protective cover of the GNSS / INS combined navigation equipment as the base, and the protective cover is integrally formed. The support rod uses a large-diameter hollow cylinder, which ensures the safety and reliability of the laser radar equipment mounting frame. In the design of the overall chassis support, a combination of aluminum profiles is used and corner bolts are used to connect and fix it, which has the advantages of low cost and strong stability.

[0004] However, after research, it was found that the device did not have a structure to adjust the height of the surveying and mapping structure. After the surveying and mapping was completed, there was no structure to protect the surveying and mapping structure. External rain and dust would pollute the surveying and mapping structure. Therefore, the surveying and mapping structure needed to be disassembled after use, which was not convenient to use. There was no structure to clean the surveying and mapping structure. Dust could easily contaminate the lens of the surveying and mapping structure, affecting the accuracy of the surveying and mapping. Utility Model Content
