Pool column measuring system based on BIM and three-dimensional laser scanner, and measuring method

Abstract

The invention provides a pool column measuring system based on BIM and a three-dimensional laser scanner, and relates to the technical field of pool surveying and mapping. The three-dimensional laserscanner acquires three-dimensional point cloud data at all positions of a column, a camera acquires pictures of the column and transmits the pictures to a three-dimensional modeling unit at the same time to establish a three-dimensional model, and a BIM modeling unit constructs and stores a complete pool column BIM model. A pool column measuring method comprises the following steps of erecting thethree-dimensional laser scanner and the camera according to actual situations; acquiring the three-dimensional point cloud data at all positions of the column by utilizing the three-dimensional laserscanner, and acquiring the pictures of the column by utilizing the camera; importing the obtained data and pictures into a computer, and generating a three-dimensional column model by utilizing a three-dimensional modeling tool; and importing the model data into a BIM modeler to construct the complete pool column BIM model. According to the system and the method, various pool columns can be rapidly and accurately measured, the safety is high, the labor intensity is low, and different working environments can be met.

Description

technical field [0001] The invention relates to the technical field of pool surveying and mapping, in particular to a pool column measurement system and measurement method based on BIM and a three-dimensional laser scanner. Background technique [0002] Since entering the 21st century, my country's economy has entered a stage of rapid development, and at the same time, the speed of urban modernization has been greatly increased. Many old pools designed by domestic and foreign experts can no longer meet today's needs, and the capacity of pools required today has far exceeded the design requirements at that time. Urgently in need of updating to build a larger pool. To measure the pool that has been built or is under construction, that is to measure its various parameters according to the provisions of the measurement technical specifications, judge whether it meets the design requirements, and generate two-dimensional graphics or three-dimensional models for testing needs. ...

AI Technical Summary

Problems solved by technology

However, the process of generating two-dimensional graphics is complicated, and at the same time, point cloud data cannot be collected during measurement, so the data acquisition is still relatively slow; at the same time, the three-dimensional model cannot be generated immediately, and the details of various places on the column cannot be restored. People have the feeling of being in the pool and inspecting and watching the columns

[0012] Simultaneously, no matter it is prior art 1 or prior art 2, there is a common shortcoming that just can't detect the place that people can't reach.
