Building construction quality actual measurement data acquisition device

Abstract

The invention discloses a building construction quality actual measurement data acquisition device. The device comprises a vehicle body, a control mechanism and a data acquisition mechanism, the vehicle body comprises a rear suction cup set, a rear vehicle frame base, a steering engine, a gear, a rack, a front suction cup set, a front vehicle frame base, a spherical hinge and an electric push rod.The control mechanism comprises a single-chip microcomputer, a controller, a battery and a power switch; the data acquisition mechanism comprises an ultrasonic sensor and a three-dimensional laser scanner. The building construction quality actual measurement data acquisition device can rapidly, effectively, completely and automatically move and can achieve the building construction quality actualmeasurement data acquisition with high-precision so as to achieve the complete and high-precision measurement for the whole object to be measured and directly perform rapid reverse three-dimensionaldata acquisition and model reconstruction from the measured object, and each piece of three-dimensional data in the laser point cloud is the real data of the directly measured object, so that the acquired actual measurement data is real and reliable, the traditional single-point measurement method is broken through, and the labor and time are effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of building measurement, and in particular relates to an actual measurement data acquisition device for building construction quality. Background technique [0002] In the construction of engineering projects, the quality of the project is very important. The current method of testing the quality of the construction is to manually use measuring tools such as tape measure, ruler, and feeler gauge to measure and measure. The workload of measuring according to the requirements of the specifications will be very large, and due to Taking the method of randomly selecting measuring points, the measured data is not comprehensive enough, and there are certain errors in the measured data, so it cannot accurately reflect the actual situation of the entire building construction quality.

Problems solved by technology

[0002] In the construction of engineering projects, the quality of the project is very important. The current method of testing the quality of the construction is to manually use measuring tools such as tape measure, ruler, and feeler gauge to measure and measure. The workload of measuring according to the requirements of the specifications will be very large, and due to Taking the method of randomly selecting measuring points, the measured data is not comprehensive enough, and there are certain errors in the measured data, so it cannot accurately reflect the actual situation of the entire building construction quality

[0003] At the same time, in some concealed and dangerous places, such as super high-rise exterior walls, floor tops, etc., it is often difficult to carry out manual measurement. Using existing measurement tools such as theodolite, only single-point measurement can be achieved, and it is difficult to measure comprehensively. Find out the verticality, flatness, hole size, etc. of the entire surface

[0004] The 3D scanning technology used in other fields now generally uses the scanner installed on a measuring tripod, so that every time a measuring point is changed, it needs to be re-leveled and installed, which is cumbersome and cannot be automatically moved to other measuring points according to the actual measurement requirements. It is not possible to move freely on the wall and floor, and at the same time, it cannot measure the internal conditions of the scanned object, such as wall thickness, floor thickness, plastered wall hollowing, etc.
