DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a simulation system to be used for trial driving etc.
DESCRIPTION OF THE RELATED ART
In conventional simulation systems, it is common to project an animation sequence composed by computer graphics onto the screen in front of a user.
However, this kind of conventional simulation system has a problem of not being able to obtain realism as the picture viewed by the user is only an animation.
SUMMARY OF THE INVENTION
In view of the previous problems, the object of the present invention is to provide a simulation system which excels in realistic portrayal.
To attain the above object, the present invention provides a simulation system which comprises a simulator body which simulates an operation of the conveyance, an output information collecting device for collecting the information outputted to said simulator body, and a communication circuit which connects said simulator body to said output information collecting device.
The output information collecting device of the simulation system of the present invention comprises a conveyance model operated according to the operation information received from the outside. The above conveyance model comprises a television camera which shoots the surrounding view to be passed to the simulator body, and an acceleration detector which detects the acceleration of the conveyance model to be passed to the simulator body.
The above simulator body of the simulation system in the present invention comprises a cockpit device comprising an operating seat, a driving section which displaces the above cockpit device, and an output section which displays the picture taken by the above television camera. The above cockpit device comprises an input section for driving which receives the input of the operation information that operates the above conveyance model. The above driving section displays the cockpit device according to the information of acceleration received from the above acceleration detector.
The output section comprises a displaying device provided at the front section of the above cockpit device and a projector which projects the picture taken by the television camera to the above displaying device, wherein the above projector is preferably supported in such a condition that it is not subject to influence of the displacement of the above cockpit device. Further, the above projector may be supported at a section different from the cockpit device, or it may comprise a vibration eliminating mechanism. A vibration eliminating mechanism which comprises an optical axis changing mechanism that changes the direction and the position of the optical axis may be used. The above optical axis changing mechanism displaces the optical axis projected by the above projector to cancel the displacement of the cockpit device by the above driving section.
Further, the above television camera comprises a shooting section, wherein the above shooting section comprises a photoelectric conversion mechanism which converts light to electric signals, an optical system which conducts the image of the subject to the above photoelectric conversion mechanism, and an incident light path changing mechanism which changes the path of the light within the above optical system. It is preferable that the above conveyance model detects the degree of deflection based on the information of acceleration received from the above acceleration detector and comprises a controlling mechanism in the light path changing mechanism which changes the light path of the incident light according to the above degree of deflection so that the light emitted from a certain position of the project or will be incident at a certain position of the above photoelectric conversion mechanism in spite of the deflection.
It is preferable that the above television camera comprises a front television camera which shoots to the front and a rear television camera which shoots to the rear, wherein said output section further comprises a rearview-mirror-form displaying device and side-
