Description
Technical Field
The invention relates to the technical field of constructional engineering detection, and particularly discloses a real estate building area measuring device.
Background
With the rapid development of social economy, buildings become a beautiful landscape of contemporary society, and developers can check and measure the quality and the building area of the buildings after the buildings are built, and then can hand over the buildings to owners, wherein the developers are not poor, most owners do not have experience of checking the buildings when receiving the buildings, and the developers can know the quality of the buildings. For the owner, the quality of the house is measured as a first measurement index, and whether cracks exist in the building wall is checked. The crack not only affects the beauty, but also gives the building structure whether to knock the alarm clock safely, the existing wall crack detection is generally detected by shooting analysis, such as a crack comprehensive tester, which mainly comprises a portable color display host, a color microscopic amplification probe, an ultrasonic testing probe and the like. During testing, a user can directly read the detection value of the width or the depth of the crack from the liquid crystal screen of the host computer, and can also take a picture of the crack to be recorded (the width and the depth of the detected crack can be reserved in the shot picture). The crack comprehensive tester has high cost, and the shooting analysis often causes inaccurate detection data due to weather change.
