Problems solved by technology

[0003] Existing laser radar is mostly used for 3D measurement and positioning equipment, relying on laser radar for measurement, after measurement, objects are identified and modeled to realize three-dimensional measurement and positioning, but when the existing measurement and positioning devices are used, often the laser radar cannot be rotated Or moving, the measurement angle of view is very limited, and it is easily affected by the cover, resulting in insufficient measurement accuracy. The existing measurement positioning device has poor support when used, and it is easy to cause damage to the laser radar in harsh environments, and the existing measurement positioning device The device is less convenient to use and the device is cumbersome
