Application of Laser Rangefinders in Housing Measurement
The application of laser rangefinder in house measurement has always been a concern and concern for the housing management department. The house survey area map is directly used as an attached drawing of the property ownership certificate and has legal effect. It is not only directly facing the people, but also directly related to the economic interests of the people, so the control of measurement errors in housing is particularly important. According to past habits, using tape measures or steel tapes to measure building area and usage area can also meet basic requirements. However, there are significant errors in long-distance measurement, floor height measurement, and difficult to reach measurement, as well as disadvantages such as high labor intensity and complex work. In today's rapidly developing high-tech society, such primitive and traditional measurement methods are clearly not in line with the requirements of today's information society for rapid and efficient measurement.
Therefore, after introducing a handheld laser rangefinder and several months of practical use, it is generally believed that this instrument is particularly suitable for measuring complex building structures, mid to high rise buildings, and long-distance buildings. Easy to use, measurement data (3mm accuracy), improved work efficiency (non-contact measurement is possible), completely abandoning the method of measuring houses with a tape measure (or steel tape measure), reducing surveying errors, ensuring area measurement accuracy, and making the measurement results more convincing to homeowners. Of course, there are also aspects of the instrument that urgently need improvement, such as difficulty in seeing long-distance target objects under strong sunlight, which requires the use of telescopes and other accessories. In addition, calibrating the level bubble during each measurement is quite laborious, but it should be able to automatically calibrate.
