Description

Technical Field

[0001] This application relates to the technical field of measuring equipment, and more particularly, to an automated building measurement device. Background Art

[0002] During the acceptance process of building interiors for handover, accurate spatial dimension measurement is crucial for ensuring building quality and meeting design requirements. Traditional measurement techniques mainly rely on 3D laser scanners, which can provide high-precision 3D coordinate values and capture spatial structures in detail. However, despite the advantages of high precision of 3D laser scanners, their dense point cloud measurement method brings problems such as complex data processing, high consumption of computing resources, and high time costs. In addition, high-precision 3D laser scanning equipment is expensive, and the purchase and maintenance costs are relatively high, which limits its widespread popularity in practical applications. Another single-point laser automatic measurement solution often fails to accurately measure door and window sizes and wall flatness due to defects in the laser distribution and structural design of existing measurement equipment, which are crucial in the acceptance of building interiors, resulting in inaccurate measurement and low efficiency.
