Abstract

The utility model relates to a tunnel scene device, which comprises a plurality of pictures with continuous actions which are affixed on wall of the tunnel and light polarizing plates covering the pictures. The light polarizing plate is made up of a frame and a plurality of light polarizing sheets which are vertically arrayed with intervals. Direction of each light polarizing sheet is above visual line between view point and image plane. Black surface of the light polarizing sheet can absorb light, and the light polarizing sheet is wide enough to block adjacent picture. The utility model utilizes the light polarizing sheet retaining adjacent picture, assure people can see one picture once, eliminate interference of adjacent pictures, reinforce visual persistence and reduce twinkling. The utility model can display continuously the pictures divided by continuously actions, so as to improve advertisement effect and interest of the pictures.

Description

The tunnel video device

Technical field

The utility model relates to a kind of tunnel video device, but is used for still frame is become motion picture.The tunnel that utilizes existing subway, railway, highway etc. is as carrier, and device has the picture of continuous micromotion on its wall, utilizes the speed that vehicle travels and a kind of special video display that produce dynamic effect are felt in the tunnel.

Background technology

Many propagandas or advertisement picture have been provided with in both sides, tunnel such as subway, railway, highways at present, for the propagation of civilization plays an important role.But these pictures are all fixed, and its effect of publicity is not good.

Summary of the invention

The purpose of this utility model just provides a kind of tunnel video device with animation effect.

The technical solution of the utility model is: this device constitutes by the picture of continuous action and the Polarizer that covers on every width of cloth picture successively by investing on the tunnel wall several, this Polarizer is made of frame and the vertical polaroid alternately of multi-disc, the direction of each polaroid all in viewpoint to the sight line between the picture, the surface of polaroid is the black light-absorbing face, and its width can block and face picture mutually.

The utility model utilizes Polarizer to block adjacent picture, guarantees can only to see an auspicious picture at every turn, gets rid of the both sides picture and disturbs and strengthen persistence of vision and reduce to flash.Reach the picture effect that a plurality of pictures that decompose by continuous action is shown as continuous motion, strengthened the effect of publicity and the interest of picture greatly.

Description of drawings

Fig. 1 is a formation synoptic diagram of the present utility model;

Fig. 2 is the schematic perspective view of the utility model Polarizer;

Fig. 3 is the A-A cut-open view of Fig. 2;

Fig. 4 is that the vehicle window of people in the compartment observed situation figure of the present utility model.

Embodiment

Referring to Fig. 1-Fig. 3, the utility model constitutes by the picture 1 of continuous action and the Polarizer 2 that covers on every width of cloth picture successively by investing on the tunnel wall several, this Polarizer 2 is made of frame 2 and the vertical polaroid 22 alternately of multi-disc, the direction of each polaroid 22 all in viewpoint to the sight line between the picture 1, the surface of polaroid 22 is the black light-absorbing face, its width can block and face picture mutually, promptly when the dead ahead of beholder at a width of cloth picture, its sight line is just in time passed the gap between the polaroid 22, can see this width of cloth picture.And when seeing the picture adjacent, obstructed the view by the polaroid 22 of adjacent pictures with this picture in this position.

So the width of each polaroid 22 is as the criterion can stop adjacent sight line.

Referring to Fig. 4, when the vehicle window 5 in the compartment 4 that is travelling is watched the utility model on the tunnel wall, when a certain picture 1 is positioned in the middle of the beholder visual field, the direction of the polaroid 22 in people's sight line and the Polarizer of the present utility model 2 is parallel, so the image in the middle of can be observed on the width of cloth picture 1, two width of cloth of the front and back that are adjacent and the image of other picture are then sheltered from and can not see by the polaroid 22 of the Polarizer 2 on each width of cloth picture.Under observation picture in an instant, people's sight line can move a slight distance simultaneously with picture, both relative velocities are zero, are equivalent to persisting of picture.

The utility model is according to the design of the image-forming principle of film.

Film is the persistence of vision according to the people, shows out 24 auspicious continuous action pictures in a second.These continuous pictures are to be imprinted on long film to examine on the shellfish, examine shellfish and are by the rotation of film projector and advance sheet at high speed.The tunnel video device is copied these characteristics exactly, and on long tunnel wall, travelling forward of the vehicle of running at high speed replaces the rotation of film projector, and forms this special landscape with continuous picture making.In brief: be about to projection and examine shellfish, the relative motion of garage and picture is reversed dexterously.In the motion picture projection process, be to utilize moment of the baffle plate of beating at a high speed and Kao Bei to pause to produce persistence of vision and reduce to flash.Utilize polarization light technology to block the both sides picture, guarantee to see an auspicious picture at every turn.Reach and get rid of the both sides picture and disturb and strengthen persistence of vision and reduce to flash.

Making illustrates; As speed of a motor vehicle 80km/h, promptly per 1 second/24 strokes are 92cm.If each picture height is 80cm, wide is 92cm.Polaroid setting height is 80cm under the normal condition, and wide is 2cm, and thick is 0.2mm.The polaroid spacing is 1cm.By front explanation installation.

Claims

1, a kind of tunnel video device, it is characterized in that: this device constitutes by the picture of continuous action and the Polarizer that covers on every width of cloth picture successively by investing on the tunnel wall several, this Polarizer is made of frame and the vertical polaroid alternately of multi-disc, the direction of each polaroid all in viewpoint to the sight line between the picture, the surface of polaroid is the black light-absorbing face, and its width can block and face picture mutually.
