Embodiment
Embodiment:
The overall work schematic diagram of the utility model head video perspective three-dimensional display mainly is made up of manual transmission 23, grating chi 24 and single-chip microcomputer counting circuit 22 three parts as shown in Figure 1, and its concrete structure is as follows:
The structural representation of the utility model head video perspective three-dimensional display includes 2,13, two camera angular setting pieces 1,11 of two cameras shown in Fig. 2,3,4,5,5,16, two slide blocks 6,17 of two slide block web members, guide rail 19, guide rail fixed plate 8,12,15, two feed screw nuts 3,14 of 4, two main shaft screw mandrels of main shaft screw mandrel fixture, grating chi main scale 7, grating ruler reading head 18, anaglyph spectacles 10, anaglyph spectacles carriage 9.
In the present embodiment, above-mentioned two cameras 2,13 cling on two camera angular setting pieces 1,11 by multi-purpose adhesive respectively.Two camera angular setting pieces 1,11 are connected by the through hole of hexagon socket head cap screw with two slide block web members 5,16.Like this, the adjustment of angle can realize by the angle of adjusting between 1,11 and two slide block web members 5,16 of two camera angular setting pieces between two cameras.
In the present embodiment, grating chi 24 is used for measuring the translational movement of camera 13 and since about the translational movement of two cameras 2,13 identical, the direction that moves is opposite.Therefore, behind the translational movement of measuring one of them camera, can extrapolate the actual range of 2 cameras.The grating main scale 7 of grating chi 24 is fixed on the guide rail fixed plate 8, and grating ruler reading head 18 is installed on the slide block 17, along with slide block moves together.When shaking the main shaft screw mandrel, grating ruler reading head is along with slide block moves together, and produces Moire fringe with grating chi main scale.Light activated element in the grating ruler reading head changes into electric signal with the Moire fringe light signal, is made into through amplifying, and exports 2 TTL square waves.Single-chip microcomputer calculates the square wave number that is obtained, thereby extrapolates the translational movement of camera.
In the present embodiment, main shaft screw mandrel fixture 15 is fixed on the guide rail fixed plate 8 by two hexagon socket head cap screws, entangles screw mandrel main shaft 4 with screw mandrel fixture 12 simultaneously, avoids the move left and right of screw mandrel main shaft 4 like this.Place feed screw nut 14 on above-mentioned slide block web member 16 through hole 28 on it.Feed screw nut's fixing means is to use two hexagon socket head cap screws to be inserted into respectively in two through holes 30,31 and two through holes 27,29 on the slide block web member 16 of self, and feed screw nut 14 and sliding fast web member 16 are fixed up.In like manner, slide block web member 5 links together by similar method with feed screw nut 3.Simultaneously, main shaft screw mandrel 4 forms tangential force with feed screw nut 3,14, and when shaking main shaft screw mandrel 4, its tangential force converts translation power to, promotes two camera 2,13 side-to-side movements.
In the present embodiment, the main shaft both sides of main shaft screw mandrel 4 are processed to the opposite screw thread of rotation direction respectively.Like this, two cameras are just opposite in the direction that moves, and realize the dwindling and increase of distance between two cameras.
Principle of work of the present utility model is as follows: two camera motions mutually under the effect of main shaft screw mandrel, grating main scale 7 and grating ruler reading head 18 relative displacements simultaneously, the light activated element of grating ruler reading head 18 the insides changes into analog voltage signal with the Moire fringe light signal, and change into digital signal by amplifying shaping, send into single-chip microcomputer counting circuit 22.Single-chip microcomputer counting circuit 22 mainly is made up of single-chip microcomputer and support circuit thereof, be mainly used in and connect grating chi and computing machine, grating ruler reading head 18 output signals are counted, extrapolate two distances between the camera and also a distance value that calculates is sent in the computing machine 25, make things convenient for computing machine to be further processed.
Two cameras of lead screw transmission mechanism 23 are used to obtain the true environment signal that images of left and right eyes should be seen, and the frame of video signal is transferred on the computing machine by USB interface.Computing machine gets access to behind the frame of video signal through corresponding processing, passes back in the three-dimensional liquid crystal glasses by the VGA display interface.Like this, the user just can see the dummy model that can see also that in the true scene in his the place ahead computing machine produces by three-dimensional liquid crystal glasses, realizes that actual situation merges.
