Handheld laser scanner for indoor door and window measurement

Abstract

The present invention provides a handheld laser scanner for indoor door and window measurement. The scanner comprises a gyroscope module (11), a scanning module (12), an indication laser unit (13), acontrol unit (14), a wireless transmitting-receiving module (15) and a battery pack (16). The scanner is employed to perform measurement of dimensions of doors and windows indoors to obtain accurate measurement data, a mobile phone client is employed to achieve record and management of the measurement data, a corresponding design is cooperated, and therefore, compared to a traditional measurementmeans, the scanner provided by the invention can perform measurement of doors and windows indoors with no need for professionals, common usage personnel only need simple operation to obtain a measurement result being the same a measurement result obtained by the professionals, the scanner is employed to greatly reduce the measurement time compared to the traditional measurement mode, measurement of common doors and windows only needs tens of seconds, automatic record can be performed, and the working efficiency can be greatly improved.

Description

technical field [0001] The invention relates to a hand-held laser scanner for indoor door and window measurement, belonging to the technical field of indoor measurement. Background technique [0002] Laser three-dimensional scanning technology is a breakthrough in surveying and mapping technology that has emerged in recent years. Through high-speed laser scanning measurement, the spatial position information of the surface of the measured object can be quickly obtained with large area and high resolution, and a high-precision digital model can be obtained. 3D scanning technology has been successfully applied in cultural relics protection, urban surveying and mapping, highway and railway construction, bridge and tunnel monitoring and other fields. The spatial point cloud data obtained by 3D laser scanning technology can quickly establish a 3D visualization model of complex and irregular scenes, saving time and effort, which is incomparable to manual measurement.
