Description
Technical field
The utility model relates to industrial optical 3-dimensional coordinate measurment instrument field, is specifically related to a kind of adjustable beam structure of industrial optical 3-dimensional coordinate measurment instrument.
Background technology
Along with modern science and technology and industrial development, increasing field has proposed to measure needs to parameters such as the three-dimensional dimension of workpiece and surface profiles.In a lot of industries and field (as auto manufacturing), measuring oneself detects in being deep into production run online.In some heavy constructions, need Site Detection.At present, the three-dimensional dimension quality testing for being less than 1m length workpiece, does not have problems substantially, adopts three coordinate measuring machine, joint arm etc. to complete more.And for the workpiece of 1m～30m length, as various heavy castings, forging, stamping parts, working of plastics, structural member and heavy mechanical equipments such as automobile die, automobile panel, aircraft components, ship components, wind power generation blade, heavy mechanical equipments, adopt that traditional contact-type 3 D measuring technique speed is slow, range is restricted, inconvenient operation, sometimes even cannot measure.So, for the three-dimensional dimension detection of medium-and-large-sized workpiece, be the Focal point and difficult point of commercial measurement research always.
Traditional measuring method comprises articulated type coordinate measuring machine (Articulated Arms), three coordinate measuring machine (CMM) and transit survey system (Theodolites) etc.
Articulated type coordinate measuring machine is due to the restriction of joint brachium, and its measurement range limited (the longest can arrive 4m), for large-size workpiece, must carry out coordinate conversion repeatedly, namely " leapfrogs ", and once loss of significance leapfrogs at every turn.
Three coordinate measuring engine measurement shortcoming one is to belong to contact type measurement mode, be difficult for alignment characteristics point, to measurement environment require high, not portable, measurement range is little; Shortcoming two is that huge three coordinate machine expense is high, measurement range is limited, measure the above size cost of equipment of 4m over 4,000,000 yuan, and must there is a good station, requirement for environmental conditions is high, measured piece is put and is adjusted difficulty, and need foundation and the surveying program that carries out detection coordinates system consuming time early stage, can not meet the manufacture detection efficiency requirement of measured piece.
Target is manually sighted in the general employing of transit survey system, point-to-point measurement, and measuring speed is slow, automaticity is not high, and complicated operation is very high to operating personnel's requirement.It establishes station location, pointing accuracy, it is larger on the impact of net result to sight the factors such as number of times.
In sum, it is slow that traditional measuring method exists measuring speed, and the collection of surface of the work point data volume is inadequate, can not for specific products, customize the defects such as detection, is not especially suitable for measurement and the detection of large-scale workpiece.
For meeting society need, industry optical 3-dimensional coordinate measurment instrument is in having come out in the last few years, the theoretical foundation of the exploitation of industry optical 3-dimensional coordinate measurment instrument is based on computer binocular vision technology, by two angled synchronous shooting, collecting images of industrial CCD camera, finally, to the image calculating of decoding, obtain the three-dimensional coordinate of hand-held target chaining pin.
The hardware of industry optical 3-dimensional coordinate measurment instrument is mainly comprised of the fast scaffold tower of three-dimensional and hand-held target two parts, and wherein three-dimensional fast scaffold tower is provided with horizontally disposed crossbeam, is symmetrically installed with two CCD cameras on crossbeam.During use, described two CCD cameras (camera1 in Fig. 1 and camera2) are taken deformable object simultaneously, utilize the calibrating parameters of camera, to the image calculating of decoding, obtain the three-dimensional coordinate of hand-held target gauge head, be usually said " binocular stereo vision method ", its principle of work can be with reference to shown in Fig. 1.
Yet, on existing industrial optical 3-dimensional coordinate measurment instrument for the crossbeam of CCD camera is installed, its length is immutable, if CCD camera adopts the mode being completely fixed to be arranged on crossbeam, the spacing of two CCD cameras just can not regulate so, so just cause the measurement range of industrial optical 3-dimensional coordinate measurment instrument less, and be unfavorable for promoting the use of of industrial optical 3-dimensional coordinate measurment instrument.
