Abstract
The present invention relates to a navigation brows system of a digital sand table, belonging to the digital sand table model system. The navigation browse system of the digital sand table is used to solve a problem that hysteresis or inconsistency of the image display of a physical model and a projective model results in the poor projective effect in the prior art. A specific scheme is that: the navigation browse system of the digital sand table includes a control host (1), the physical model (2), a RFID card reader (3), and a projector (4), wherein, the interior of the physical model is inserted with an RFID chip, the RFID card reader is connected with the control host in a communication manner, and the projector is connected with the control host in a communication manner. The physical model is connected with the RFID card reader in a wireless communication manner. According to the technical scheme, the RFID card reader transmits the chip information to the control host, and the control host adjusts and transforms the image of the projector according to the information of various chips so that the problem of hysteresis or inconsistency of the image display of the physical model and the projective model is effectively solved and consistency of the images of the physical model and the projective model is ensured.
Description
Technical field
The present invention relates to a kind of digital sand table model system, especially relate to a kind of by wireless signal identification physical model, and can to the navigating and browsing system of the digital sand table that the physical model image of projection all around moves, rotates, amplifies and reduces.
Background technology
Along with the development of multimedia technology, traditional display form cannot be approved by masses again, and spectators need more multimedia show form, and therefore digital sand table model also instead of traditional sand table model gradually.Digital sand table model mainly comprises two kinds of forms: one is on originally traditional sand table model, increase multimedia projector system; Two is pure 3-dimensional digital sand tables, generally has interaction function, and projecting plane is generally white or the grey curtain face of special processing, does not have entity sand table model.Merged mutually with solid model by sound, optical, electrical, image, three-dimensional animation and computer program-control technology.
For the first form, just just simple sand table model and shadow casting technique being combined in existing technology, can produce physical model in projection process and the display of projection model picture exists delayed or inconsistent situation, causes drop shadow effect poor.
For the interaction function of 3-dimensional digital sand table in prior art, mainly realize the switching between different digital model by employing game class operating grip or use button, these two kinds of implementations have the defect existed separately; Game class operating grip is only to realize the movement all around at visual angle, the amplification of digital model cannot be realized, reduce, the function such as rotation, and the less stable of game class rotating disk, long operation cannot be realized, use button to carry out the switching of digital model, although can handoff functionality be realized, experience sense for spectators is poor, cannot realize the effect that physical model is corresponding with digital model, and button easily damages, maintenance cost is higher.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide and a kind ofly effectively solve physical model and the delayed or inconsistent problem of projection model picture, the navigating and browsing system of the digital sand table that can projection model picture be moved, rotates, amplifies and be reduced simultaneously all around.
In order to solve the problem, the technical solution used in the present invention is: a kind of navigating and browsing system of digital sand table, comprises main control system, physical model that inside is fitted with RFID chip, the RFID card reader communicated to connect with described main control system and the projector communicated to connect with described main control system; Described physical model is connected with described RFID card reader radio communication.By the RFID card reader being inserted into RFID chip in physical model and communicate to connect with described main control system, achieve the projection of physical model image; The RFID chip information of installing due to each physical model is all different, when different physical models being placed in the scope that RFID card reader can read, just can obtain different RFID chip information, chip information is transferred to main control system by RFID card reader, main control system carries out adjustment conversion according to different chip informations to the picture of projector, efficiently solve physical model and the delayed or inconsistent problem of projector model picture, ensure that the consistance of physical model and projector model picture.
In order to the operability of projector model picture can be made stronger, what the present invention did is improved to: on the basis of technique scheme, increase by a three-dimensional navigation controller communicated to connect with described main control system.See mould person and can carry out navigating and browsing by three-dimensional navigation controller to the digital model picture that current projector shows, the function of navigating and browsing mainly comprises: all around moving model, the mitigation and amplification of local, getting a bird's eye view of whole digital model, and rotate functions such as browsing.
In order to ensure the accuracy of the RFID signal in the physical model that main control system reads, the improvement that the present invention does is: on the basis of above-mentioned the first string, increase by a Signal Booster, and described RFID card reader is communicated to connect by described Signal Booster and described main control system.RFID information in the physical model that RFID card reader reads strengthens further through Signal Booster, and the RFID information that main control system is received is more accurate, ensure that the consistance of projection model picture.
In order to ensure that main control system reads the accuracy of three-dimensional navigation controller navigation signal, the improvement that the present invention does is: on the basis of above-mentioned the first string, increase by a Signal Booster, is communicated to connect by described three-dimensional navigation controller by described Signal Booster and described main control system.The navigational control signals of three-dimensional navigation controller amplifies by Signal Booster, and the navigational control signals that main control system is received is more accurate, ensure that the degree of accuracy of Navigation Control.
