Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping, in particular to a house area surveying and mapping device. Background Art

[0002] With the rapid development of real estate and the improvement of living standards in recent years, housing prices are also rising. Most people will consider purchasing a house after they have a certain amount of savings. In order to ensure fairness and justice, after the construction of the house is completed, the developer will measure the area of ​​the house, and then sell it at the total price of the house multiplied by the area of ​​the house per square meter. When the owner inspects the house, the area of ​​the house will also be re-measured. Therefore, there is a need to survey the area of ​​the house when the construction of the house is completed and the house is delivered. The area of ​​the house is mainly achieved by measuring the length. The traditional measurement method is to use a tape measure, but the use of the tape measure is limited. There will be places that the tape measure cannot measure, and the tape measure is soft, so it is difficult to measure. When measuring a long length, the tape measure will bend and the accuracy of the data cannot be guaranteed. Therefore, the commonly used measuring tool is the laser rangefinder. The laser rangefinder is placed at a point. After the laser rangefinder emits a laser to the opposite side, the distance between the opposite side and the laser rangefinder can be automatically obtained. However, there is a lot of dust after the house is built. During the use of the laser rangefinder, dust will be stuck on its transmitter and receiver, affecting the emission and reception of the laser, and the accuracy of the length measurement cannot be guaranteed. In addition, the laser rangefinder is generally placed close to the wall when in use. When using the current laser rangefinder, most of the tail of the laser rangefinder is placed on the wall manually, and it cannot be guaranteed that the laser rangefinder has been set close to the wall, so there is an error in the measurement result.
