Abstract

The oblique stingy picture prison screen that can be seen that figure is to provide a visual image for weather forecast host, makes screen in the blue that remains captured by the angle of videocorder, and host is from oblique side position it can be seen that a map graph. Host can point to the position on map by handle easily, recovers the effect of explanation geographical knowledge, it is possible to give directions the position in certain city exactly; Coordinate the change of figure, it is possible to the movement of dynamic demonstration weather system. Host can select optimum position before screen, it is not necessary to is " fixed " on specific " point ".

Description

The oblique stingy picture blue screen that can be seen that figure

Technical field

This technology relates to scratching the blue screen as technology. Specifically scratch the screen as technology exactly and can show that image is supplied to host from prism, be used in the recording etc. of television weather forecast.

Background technology

" host reports weather and have employed stingy as technology. Host is blue behind, scratches as afterwards, the blueness in every picture all can bleach, then will scratch the image overlay of blueness before map, what so see is exactly that host stands in explanation before map. So, meteorological host is in fact exactly before the blue wall of one side " setting the world to rights ", and rapidly and precisely giving directions geographical position is a very difficult thing really. " at present, each province and city meteorological observatory is also imitating. But the level of the every host of China Meteorological Administration can not be reached, refer to that wrong position maybe dare not go the phenomenon referred to of common occurrence with hands.

Summary of the invention

In order to be able to make host to teach like that as geographical teacher, accurate rand explanation limit Location. The present invention can provide a visual image for host, makes screen in the blue that remains captured by the angle of videocorder, and host is from oblique side position it can be seen that a figure--map. The simplest map boundary line with one fixed width that can carve with blue color plane, then with the plate of other color blue picture support on blue bottom surface. Owing to support width is narrow, can't see it from the angle of video camera, still obtain the effect of blue screen. Host is close to screen, except figure be can't see and centered by the point of host's eyes normal to screen in the region being perpendicular to head, outside the lines of outside directions of rays can not be seen. The figure in all the other places is it will be seen that such as Fig. 1. In figure, A is boundary graph; Support on Blue screen, with light blue be coated in bottom surface time it can be seen that figure such as B; Formal with blue bottom surface time, it is seen that be C in figure, arrow indication place cannot see that. This figure makes by the method for translation, so horizontal direction can not be shown, has any different with the effect of eye-observation.

The method improved be line become a little interrupted. The region being thus only perpendicular to head be can't see, and has no effect on use, such as Fig. 2. Comparison diagram 1 and Fig. 2 effect improve significantly.But simple method is perfect not after all, a fixing map can not meet use needs. Want to change flexibly figure, it is necessary to design better structure.

Using this screen, host can point to the position on map by handle easily, it is possible to reaches the effect of explanation geographical knowledge, it is possible to give directions the position in certain city exactly,Coordinate the change of figure, it is possible to the movement of dynamic demonstration weather system. Host can select optimum position before screen, it is not necessary to is " fixed " on specific " point ".

This technology it is crucial that: on a blue solid screen (5), in the dynamic area needing stingy figure, transparent small cylinder is inserted by grid, play the effect passing through image from backstage, the image projected from behind face before screen shows corresponding figure, shows geographical position accurately to host (8); The one side of video camera is covered the circle of blueness or the baffle plate of ellipse by cylinder surface, makes video camera (9) still photograph blue background; The feature of transparent small cylinder is: light inlet is that transparent cylinder (1) is towards screen rear, developing end before screen is the diameter transparent cylinder shape (2) more than transparent cylinder, color development face (4) is made in cylinder end frosted, slightly embed screen (5) and avoid affecting the color of blue screen, the remaining part of transparent cylinder shape (2) is convex before screen, host is at the figure constituted close to screen position (8) visible many color development faces (4), the dark slide (3) of one circle of transparent cylinder shape (2) end face lid or ellipse, blue wash.

It is crucial that: each visualization unit is embedded in by the hole of grid arrangement; Picture plane caves in screen; Dark slide frames out a segment distance, makes oblique side it can be seen that the color of picture plane,Do not cover again the visualization unit at rear.

Accompanying drawing explanation

Fig. 1 is the design sketch carving map boundary line according to map.

Fig. 2 pastes cylinder along drawing bar interval, and its side is colored, and end face is blue, and side is it can be seen that the profile of figure, owing to there being certain interval between cylinder, distance screen 0.6-0.8 rice it can be seen that image no longer have obscured phenomenon.

Fig. 3 is simulation drawing. Partial enlargement is demonstrated the projection of " 2 " word. Screen is actually needed scope map occur and can make by 10,000 every square metre display points. City-level can do the simple type that area is little, pixel is low.

Fig. 4 is structure and the application schematic diagram thereof of transparent small cylinder. Cylinder (1) transparent in figure; Transparent cylinder shape (2); Cylinder end color development face (4); Screen (5); Host is close to screen position (8); Color development face (4); Blue shading plate (3).

Detailed description of the invention

The screen (5) that one is made up of numerous transparent small cylinders, rear has optical lantern (6) to be thrown after screen by image, makes host (8) above by numerous transparent small cylinders it can be seen that by an image formed, it is sufficient to distinguish geographical position. And the image that video camera (9) shoots is still blue screen image, synthesize for later image. Projector equipment (6) can by several the effects created more preferably; Such as ad-hoc locations such as Dynamic Announce rain belt, cold front, isothermal lines.

Claims

1. the oblique stingy picture blue screen that can be seen that figure, it is characterized in: on a blue solid screen (5), in the dynamic area needing stingy figure, transparent small cylinder is inserted by grid, play the effect passing through image from backstage, the image projected from behind face before screen shows corresponding figure, shows geographical position accurately to host (8);The one side of video camera is covered the baffle plate of the blue circle consistent with background color or ellipse by cylinder surface; The feature of described transparent small cylinder is: light inlet is that transparent cylinder (1) is towards screen rear, developing end before screen is the diameter transparent cylinder shape (2) more than transparent cylinder, color development face (4) is made in cylinder end frosted, slightly embed screen (5) and avoid affecting the color of blue screen, the remaining part of transparent cylinder shape (2) is convex before screen, host is at the figure constituted close to screen position (8) visible many color development faces (4), the dark slide (3) of one circle of cylindrical shape (2) end face lid or ellipse, blue wash.
