AI Technical Summary
In existing portable laser scanning devices, the transparent glass is easily affected by impacts and dust accumulation, which reduces light transmittance, interferes with laser scanning signal transmission, and increases data acquisition errors.
A device including a support and protection mechanism and a limiting component was designed. The transparent support glass is blocked by the flipping of the protective plate to prevent collision and dust adhesion, and stable scanning is achieved by the combined movement of the laser scanning component.
It improves the transmission stability of laser scanning signals, reduces data acquisition errors, enhances the durability and data acquisition accuracy of the equipment, and is suitable for mobile scenarios such as outdoor inspection.
