Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] refer to figure 1 and figure 2 , a vision- and laser-based house measurement method comprising the following steps:

[0021] (1) Look for laser emitters and cameras, such as figure 2 Laser transmitter 1 and camera 2 are shown.

[0022] (2) Calibrate the camera 2 and the laser emitter 1, and mark according to the actual house.

[0023] (3) Carry out feature detection on the house based on the camera, such as figure 2 Shown is a camera 2 (preferably a monocular camera).

[0024] (4) Accurate distance measurement of houses based on laser. Such as figure 2 Laser transmitter 1 shown.

[0025] (5) Convert the image coordinate system, the laser emission coordinate system, the product base coordinate system, and the house world coordinate system.

[0026] (6) Use OPENGL to reconstruct the house in 3D to achieve a rough visualization effect.

[0027] (7) Op...

Abstract

The invention discloses a house measurement method based on vision and laser, which comprises the following steps: (1) searching a laser emitter and a camera; (2) calibrating the camera and the laseremitter, and marking a house according to an actual condition of the house; (3) detecting features of the house based on the camera; (4) carrying out precise distance measurement on the house based onlaser; (5) performing conversion on an image coordinate system, a laser emission coordinate system, a product base coordinate system and a house world coordinate system; (6) performing three-dimensional rebuilding on the house by using OPENGL (open graphics language) to achieve a sketchy visualization effect. According to the house measurement method based on vision and laser, the precision problem is solved by laser measurement, and the visualization problem of measurement is solved by the three-dimensional rebuilding of the camera.

Description

technical field [0001] The invention relates to the fields of industrial measurement and life measurement, and more specifically relates to a method for three-dimensional measurement and reconstruction of a blank room. Background technique [0002] The housing problem has always been a major issue in the national development strategy. Although the real estate situation of "every land is expensive" has been greatly improved, people's attention to real estate has never been lowered. This means that house surveying will inevitably become a hot spot for buyers and sellers. However, there are still many common problems in the current housing surveying institutions: the first is of course the professional quality of the surveyors. Many people without professional training work on the front line, which will inevitably lead to a decline in the credibility of the measurement results; , the technical level is high or low, resulting in unsatisfactory conclusions of the measurement res...
