Abstract
A kind of house measurement method of view-based access control model and laser, comprises the following steps：(1) generating laser and video camera are found；(2) calibrating camera and generating laser, it is marked with reference to house is actual；(3) feature detection is carried out to house based on camera；(4) accurate distance measurement is carried out to house based on laser；(5) image coordinate system, Laser emission coordinate system, product base coordinate system, house world coordinate system are converted；(6) three-dimensional reconstruction is carried out to house using OPENGL, reaches rough effect of visualization.In the present invention, the measurement of laser solves precision problem, and the three-dimensional reconstruction of camera solves the visualization problem of measurement.
Description
Technical field
The present invention relates to commercial measurement and the three-dimensional measurement weight of live fields of measurement, more particularly to rough house
Construction method.
Background technology
Housing problem is always the significant problem of national development strategy, although " an inch of land is an inch of gold " real estate situation has obtained
Good improvement, but people never reduced for real estate attention rate.This also implies that house measurement will necessarily be into
For the focus of attention of both parties.But also there are many common problems in current house measurement mechanism：That stands in the breach is certain
It is survey crew's specialized capability problem, much for the person works without professional training in First Line, this necessarily causes measurement result
Public credibility decline；Also the good and bad jumbled together for house measurement mechanism, and it is low that technical merit has height to have, and causes the conclusion of Measurement results can not
It is satisfactory.
The content of the invention
In order to overcome the shortcomings of that the precision of existing house measurement mode is relatively low, accuracy is poor, the invention provides one
The house measurement method of kind view-based access control model and laser, the measurement of laser solve precision problem, and the three-dimensional reconstruction of camera solves
The visualization problem of measurement.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of house measurement method of view-based access control model and laser, the measuring method comprise the following steps：
(1) generating laser and video camera are found；
(2) calibrating camera and generating laser, it is marked with reference to house is actual；
(3) feature detection is carried out to house based on camera；
(4) accurate distance measurement is carried out to house based on laser；
(5) image coordinate system, Laser emission coordinate system, product base coordinate system, house world coordinate system are converted；
(6) three-dimensional reconstruction is carried out to house using OPENGL, reaches rough effect of visualization.
Further, methods described is further comprising the steps of：
(7) model of three-dimensional reconstruction is optimized using accurate distance, reaches accurate effect of visualization.
Further, in the step (1), video camera uses monocular linear image controller camera.
In the step (4), using laser measurement when, measurement be house surrounding distance.
Beneficial effects of the present invention are mainly manifested in：1st, the present invention use monocular-camera, greatly reduce binocular or
The expensive price that more mesh etc. are brought.2nd, by monocular-camera on Rotatable mechanism, being significantly increased monocular shooting
The problem of machine tunnel vision.3rd, solves precision problem by the measurement of laser.4th, the present invention also uses and other commercial measurements
In vision difference detection model.

Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
Referring to Figures 1 and 2, a kind of house measurement method of view-based access control model and laser, comprises the following steps：
(1) generating laser and video camera, generating laser 1 and video camera 2 as shown in Figure 2 are found.
(2) calibrating camera 2 and generating laser 1, it is marked with reference to house is actual.
(3) feature detection, video camera 2 as shown in Figure 2 (being preferably monocular-camera) are carried out to house based on camera.
(4) accurate distance measurement is carried out to house based on laser.Generating laser 1 as shown in Figure 2.
(5) image coordinate system, Laser emission coordinate system, product base coordinate system, house world coordinate system are converted.
(6) three-dimensional reconstruction is carried out to house using OPENGL, reaches rough effect of visualization.
(7) model of three-dimensional reconstruction is optimized using accurate distance, reaches accurate effect of visualization.
In above-mentioned technical proposal, in the step (1), video camera uses monocular linear image controller (Charge-
Coupled Device, CCD) camera.
In above-mentioned technical proposal, in the step (4), using laser measurement when, measurement be house surrounding distance.
Above-described embodiment is presently preferred embodiments of the present invention, is not the limitation to technical solution of the present invention, as long as
The technical scheme that can be realized on the basis of above-described embodiment without creative work, it is regarded as falling into patent of the present invention
Rights protection scope in.
