Description
Technical field
The present invention relates to a kind of building decoration method of inspection, be specifically related to a kind of building decoration three-dimensional modeling inspection method of accuracy.
Background technology
At present at building decoration construction field, to the inspection of the Modeling precision of decoration construction installation, the flatness of conventional plane can only simply use guiding ruler estimated bias, and this all can cause puzzlement in the efficiency detected and financial cost.Also really because these puzzlements, the inspection for building decoration three-dimensional modelings such as irregular stereo moulding or pattern modellings may be realized hardly, this all brings very large puzzlement to the inspection of quality of construction and the formulation etc. of acceptance criteria.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of building decoration three-dimensional modeling inspection method of accuracy that can realize the inspection of building decoration three-dimensional modeling.
In order to achieve the above object, technical scheme of the present invention is as follows:
Building decoration three-dimensional modeling inspection method of accuracy, it comprises the following steps:
1) in space to be checked, spatial digitizer is set up, by spatial digitizer and binding site cloud data software obtains the image cloud data in space;
2) from spatial digitizer deduced image cloud data to computing machine, image cloud data is opened by three-dimensional Become the picture software;
3) standard image data of ready design drawing is directed in three-dimensional Become the picture software;
4) by image cloud data and standard image data involutory on one point, then image cloud data and standard picture number are adjusted in the same size gradually, then comparison chart as cloud data and standard picture number the size difference on its outline line, thus obtain the data error of image cloud data relative to standard image data, obtain assay.
By adopting above-mentioned technological means, namely by spatial digitizer and binding site cloud data software is three dimensions synthetic image cloud data and the mode contrasted under carrying out the equal size cases of image, come effectively and obtain the data error of three-dimensional modeling exactly, thus make the inspection for building decoration three-dimensional modelings such as irregular stereo moulding or pattern modellings become possibility, effectively improve the construction quality of three-dimensional modeling, the formulation for acceptance criteria provides data basis.
Meanwhile, have employed above-mentioned technical scheme just, the present invention also had the following advantages:
1) result checked is made to have data supporting, true and reliable, convincing;
2) in operation, from first to last a people can complete, and coordinates without the need to many people, and the inspection period need not consume any material, and the efficiency of inspection is also high than routine inspection;
3) when running into tall and big moulding inspection, directly gathering moulding data without the need to personnel, eliminating Partial security hidden danger;
4) also for the establishment of relevant decorative model accuracy test standard provides foundation.
On the basis of technique scheme, the present invention can also do following improvement:
As preferred scheme, above-mentioned the 1st) in step, as needs carry out Multiple-Scan to space to be checked, by scanning target ball, space to be checked is scanned, in adjacent twice sweep, the border of the scanning area of second time scanning dock with the border of scanning area that first time scan or overlapping, and use SCENE software carries out spelling station process according to scanning the position of target ball and docking or overlapping region, thus acquisition image cloud data.
Adopt above-mentioned preferred scheme, Multiple-Scan is applicable to the situation that some site space are comparatively large, decorative model shelter is more, process by Multiple-Scan process and in conjunction with the spelling war of SCENE software, make the three-dimensional modeling of above-mentioned situation also can obtain required image cloud data exactly, higher in accuracy compared to single pass.
As preferred scheme, also comprise image data extraction step: open the image cloud data collected with SCENE software, extracted the region needing to test by cutting order, obtain the image cloud data after extracting.
Because spatial digitizer optionally can not only scan the decorative model needing to test when scanning on-the-spot, but all of scene are all scanned, this makes scan-data internal memory very large, contains a lot of useless interfering datas, for the inspection work in later stage brings inconvenience.And spatial digitizer scanning acquisition be three-dimensional is cloud data, although have visual effect, but directly can not apply to the inspection of the information such as shape and position of decorative model, so will scan the whole scanning data of the decorative model obtained from spatial digitizer the related data extracting moulding inspection, think that check data contrast provides data supporting, adopt above-mentioned preferred scheme just can the extraction of complete paired data.
As preferred scheme, the image cloud data after the extraction of being opened by three-dimensional Become the picture software, is removed part unnecessary on it by scratching figure order, the image cloud data after again being extracted again.
Adopt above-mentioned preferred scheme, can make to extract the view data obtained can be more accurate.
As preferred scheme, leave at least one object of reference in region to be checked when cutting, the follow-up relative coordinate being obtained region to be checked in three-dimensional Become the picture software by the distance measuring object of reference and region to be checked.
Adopt above-mentioned preferred scheme, can so that obtain the relative position of three-dimensional modeling when checking.
Accompanying drawing explanation
