Description
Technical field
The utility model relates to a kind of Intelligent indoor 3 D measuring instrument.
Background technology
In April, 2006 Shanghai City promulgated " Shanghai City residential project cover in quality assessment guidelines ".This guide rule is intended to clearly check and accept the part details of building engineering construction quality.For the architecture indoor size following regulation is arranged: the length and width both direction in each room is respectively surveyed 2 points, with steel ruler or laser range finder inspection; For clear height, 5 points are surveyed in larger bedroom, the Room, space, and namely 4 angle points add 1 central point, and with spirit-leveling instrument or backguy, steel ruler or laser range finder inspection, the bight measuring point is apart from wall limit 20cm.This shows that for the detection of indoor three-dimensional dimension, not only measurement data is more, measuring process extremely bothers.For the more special room of profile, can only use the original instruments such as tape measure to measure or directly do not detect.Such measurement has brought many unfavorable results: at first be the working specification that the precision measured depends on personnel to a great extent, error is large in the reality, accidentalia is also more obvious, and repeatable accuracy and confidence level are all lower; Secondly measuring speed is slow, precision is low; Can only be used for the house dimensional measurement of rule at last, and be difficult to measure for irregular room wall angle.At present, comprise paper and the product that company announces from each research institution, also do not have specialty to be positioned the instrument of indoor three-dimensional measurement, mainly concentrate on yet and doing in the analysis of reverse-engineering and mould, the application on large scale does not almost have except surveying and drawing.Be positioned the three-dimensional measurement instrument of building trade also in the Primary Study stage, such as the laser three-D automatic measuring instrument that the rich inferior checkout equipment in Shanghai company limited releases, there are the following problems for this laser three-D automatic measuring instrument:
1. the irregular data that cause in room are disturbed.There are door and window, column etc. in general room, when laser sensor scans according to certain angle along with scrambler, inevasiblely adopts a little at door and window, column etc." the false point " that convex-concave place on these walls gathers can cause great impact to data processing and screening.This requires highly to hardware, makes software programming more complicated.
2. the laser sensor loss of data causes system in case of system halt.During laser sensor work, first by the pulse of Laser emission diode pair standard target Emission Lasers.Laser is to all directions scattering after the target reflection.The part scattered light turns back to the sensor receiver, is imaged onto on the avalanche photodide after being received by optical system.Avalanche photodide is the optical sensor that a kind of inside has enlarging function, so it can detect extremely faint light signal, and is translated into corresponding electric signal.Laser range sensor commonly, it is by record and process to be issued to from light pulse and return the received time of experiencing, and measures target range.If the target that laser sensor is aimed at is glass, glass is because smooth surface, in the reflection on laser surface in table diffuse reflection few, the sensor receptacle does not receive signal; If laser sensor is aimed at window and is projected to outside window, along with laser is propagated in air, signal weakens, diffuse signal extremely a little less than, receiver does not receive signal yet.Sensor can't accept signal, and system waits pending data will cause system in case of system halt always.
3. the image data system is very huge.If per 5 ° of laser sensor is adopted a point, then adopt 18 points on average each sidewalls, utilize least square method deal with data in software systems will become very complicated.Simultaneously, to the also corresponding raising of requirement of hardware.
4. laser sensor Dynamic Data Acquiring performance extreme difference.This laser three-D automatic measuring instrument is then adopted a poor effect along with the operation of motor continues to adopt a little.
5. the huge and machine error that the causes accumulation of this measuring instrument kinematic train.
