Bracket is fixed with spatial digitizer.
Background technique
Spatial digitizer is a kind of scientific instrument, (several for detecting and analyzing the shape of object or environment in real world
What is constructed) and appearance data (such as color, surface albedo property).The data collected often are used for three-dimensional reconstruction meter
It calculates, the mathematical model of actual object is created in virtual world.These models have quite extensive purposes, and industry is set such as
Meter, Defect Detection, reverse-engineering, robot guiding, landforms measurement, medical information, biological information, criminal identification, digital historical relic
Its all visible application of classical collection, motion picture production, game creation material etc..The purposes of spatial digitizer is creation object geometric jacquard patterning unit surface
Point cloud, these point can be used to interpolation into the surface shape of object, more intensive point cloud can create more accurate model (this
Process is referred to as three-dimensional reconstruction).If scanner can obtain surface color, material patch can be further pasted on the surface of reconstruction
Figure, that is, so-called material print is penetrated.Spatial digitizer can analogize to camera, and coniform, letter is all presented in their range of visibility
The collection of breath all limits in a certain range.The two is the difference is that camera grabbed is colouring information, and three-dimensional is swept
Retouch instrument measurement is distance.Since the result measured contains depth information, often it is referred to as with deep video or apart from video.By
It is limited in the scanning range of spatial digitizer, therefore often need to convert the relative position of scanner and object or be placed in object
On electric turntable, the complete model of object is pieced together by multiple scanning.The technology of multiple unilateral model integrateds is referred to as and is regarded
Frequency is registrated or alignment, is directed to a variety of three-dimensional alignment methods.
For some small products, the settable bracket with turntable carries out it to surround and sweep existing spatial digitizer
It retouches, and is usually that man-hour manually hand-held spatial digitizer surveys and draws product for the scanning of some large products, in man-hour manually hand-held
In mapping process, there can be scan position omission, so that the three dimensional modeled segment Character losing of product, and the excessive height of product

The inboard wheel of wheel carrier 51 and the wheel of front wheel carrier 57 are placed on the periphery circle of large product, are then learnt according to measurement
Peripheral diameter determines the turning radius of mobile foundation 5, passes through position change front wheel carrier of the mobile motion bar 55 in casing 53
57 with the length of rear wheel frame 51, then tighten the first fastening screw 54 and motion bar 55 and casing 53 be fixed, pass through tool
It is clamped with the rectangular recess of the shaft of second gear 513, then drives second gear 513 to rotate by tool, rotation the
Two gears 513 engage the angle for driving the rotation of front wheel carrier 57 specified with third gear 514, to change 57 inclination angle of front wheel carrier
Degree, is fixed third gear 514 by tightening the second fastening screw 56, to front wheel carrier 57 be fixed, realization pair
The adjustment of 5 turning radius of mobile foundation afterwards turns over rollover stand 1 and makes lower slider 4 perpendicular to the ground, pushes carriage 3 mobile
It is higher by the height on 4 top of lower slider to the bottom end of the first rack-plate 28, then turns handle 36 and two-way lead screw 31 is driven to rotate,
Two-way lead screw 31 during rotation, drives the feed screw nut 32 at two-way 31 both ends of lead screw to move towards, the lead screw moved towards
Nut 32 is pushed out the first rack-plate 38 in parallel by connecting rod 33, until the limited block 37 of 38 bottom of the first rack-plate and the
The inner wall of two U-shaped boards 41 is inconsistent, so that the first rack-plate 38 is overlapped with 42 lateral wall of the second rack-plate, is removed later to upper
The support force of balladeur train 3, so that carriage 3 slides downwards under the effect of gravity, thus by the first rack-plate 38 and the second rack-plate
42 connections are integral, spatial digitizer are fixed on the supporting plate 24 of movable bracket 2 later, so that the camera of spatial digitizer
The central axis of industrial products and camera surface sweeping end face and 51 shaft of rear wheel frame that alignment needs to scan, control activity support
First motor 23 inside frame 2 drives first gear 21 to rotate, and passes through first gear 21 and the first rack-plate 38 or the second tooth
Batten 42 is engaged transmission and movable bracket 2 is driven to be moved to higher than at large product top side location, opens 3-D scanning later
Instrument is scanned, and is oriented to by front wheel carrier 57, and the second motor 59 engages biography by the second sprocket wheel 511 and the first sprocket wheel 58
Dynamic driving rear wheel frame 51 rotates, so that mobile foundation 5 is mobile according to the turning radius adjusted, when mobile foundation 5 is mobile
It is complete to drive first gear 21 to rotate by first motor 23 after a week, the first gear 21 of rotation by with the first rack-plate 38
Or second rack-plate 42 be engaged transmission drive movable bracket 2 move down certain altitude, then spatial digitizer is to new
Height carry out surrounding scanning.
