Abstract
The utility model relates to a dynamic laser-based projection and tracking sand table system. The dynamic laser-based projection and tracking sand table system is characterized by comprising a main control computer, a laser positioner, a head swinging projector, a projection curtain and a tracking pick-up head; the main control computer is respectively connected with the head swinging projector and the tracking pick-up head; the head swinging projector rightly faces the projection curtain; and the laser positioner rightly faces the projection curtain. Compared with the prior art, the dynamic laser-based projection and tracking sand table system is flexible in operation, more human-oriented and the like.
Description
Technical field
The utility model relates to a kind of sand table control correlation technique, especially relates to a kind of dynamic projection based on laser and follows the tracks of sand table system.
Background technology
In the existing technology, for the layout that mutual exhibition need be provided in the venues such as museum, exhibition, use be mostly standard input devices such as mouse, keyboard; In fact such present situation has very big defective, and one is that mouse, keyboard all contain opereating specification, when the user is more farther than the length of mouse, keyboard chord to the distance of main control system; Just can't carry out mutual again; Another one if operation interface is very big, move on to the other end from one with mouse; Will spend the more time, but also inconvenient.
The utility model content
The purpose of the utility model is exactly to provide the dynamic projection based on laser of a kind of flexible operation, favorable expandability to follow the tracks of sand table system for the defective that overcomes above-mentioned prior art existence.
The purpose of the utility model can realize through following technical scheme:
A kind of dynamic projection based on laser is followed the tracks of sand table system; It is characterized in that; Comprise main control computer, laser locator, the projector of shaking the head, projection screen and tracking camera; Described main control computer is connected with the projector of shaking the head, tracking camera respectively, the described projector alignment projection screen of shaking the head, and laser locator is aimed at projection screen.
IMAQ card connection in described tracking camera and the main control computer is used to gather screen picture.
A kind of described dynamic projection based on laser is followed the tracks of the application of sand table system, it is characterized in that through the location of laser locator to projected position, the position of the projector projection of shaking the head is controlled, concrete steps are following:
1) use laser locator that projected position is located;
2) projector of shaking the head is projected in digital content the position of laser locator location;
3) follow the tracks of camera and judge whether laser position changes, if yes, execution in step 4), otherwise, continue execution in step 3);
4) according to following the tracks of the camera feedack, adjust shake the head projector angle and project content position, return step 3) then.
Compared with prior art, the utlity model has flexible operation, characteristics such as more humane, and adopt laser pen can increase the quantity of passage easily, have good extendability, can realize functions such as many controls are parallel.
Description of drawings
Fig. 1 is the hardware configuration synoptic diagram of the utility model.
Fig. 2 is the process flow diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
As shown in Figure 1; A kind of dynamic projection based on laser is followed the tracks of sand table system; Comprise main control computer 1, laser locator 5, the projector 2 of shaking the head, projection screen 4 and follow the tracks of camera 3; Described main control computer 1 is connected with the projector 2 of shaking the head, tracking camera 3 respectively, and the described projector 2 of shaking the head is aimed at projection screens 4, and laser locator 5 is aimed at projection screens 4.IMAQ card connection in described tracking camera 3 and the main control computer 1 is used to gather screen picture.
As scheme shown in Figure 2ly, and a kind of dynamic projection based on laser is followed the tracks of the application of sand table system, and this method may further comprise the steps:
Projected position location on step 101,5 pairs of projection screens 4 of use laser locator;
Step 102, the projector 2 of shaking the head are projected in digital content the position of laser locator 5 location;
Step 103, tracking camera 3 judge whether laser position changes on the projection screen 4, the words execution in step 104 that is, the words execution in step 103 of denying;
Step 104, according to following the tracks of camera 3 feedacks, adjustment the shake the head angle and the project content position of projector 2, execution in step 103 then.
Claims (2)
1. the dynamic projection based on laser is followed the tracks of sand table system; It is characterized in that; Comprise main control computer, laser locator, the projector of shaking the head, projection screen and tracking camera; Described main control computer is connected with the projector of shaking the head, tracking camera respectively, the described projector alignment projection screen of shaking the head, and laser locator is aimed at projection screen.
