Abstract

A risky situation is reproduced in a direct visual field of a driver driving a vehicle with a high sense of reality. A vehicle position and attitude calculation unit calculates a present position and a traveling direction of the vehicle, a driving action detector detects an action performed by the driver driving the vehicle and the condition of the vehicle, a scenario generator generates a content, position, and timing of the risky situation occurring while the driver drives the vehicle, a virtual information generator generates visual virtual information indicating the risky situation, and a superimposing unit superimposes the generated virtual information on the image of the traveling direction of the vehicle shot by an imaging unit Then, an image display unit indicates the image on which the virtual information is superimposed in the direct visual field of the driver.

Claims

1. A vehicle risky situation reproducing apparatus comprising:

an imaging unit mounted on an actually traveling vehicle to shoot an image in a traveling direction of the vehicle;

an image display unit disposed to interrupt a direct visual field of a driver of the vehicle to display the image shot by the imaging unit;

a vehicle position and attitude calculation unit that calculates a present position and a traveling direction of the vehicle;

a driving action detector that detects a driving action of the driver while driving the vehicle;

a scenario generator that generates a risky situation indication scenario including a content, a position and a timing of a risky situation occurring while the driver drives the vehicle based on a detection result of the driving action detector and a calculation result of the vehicle position and attitude calculation unit;

a virtual information generator that generates visual virtual information representing the risky situation based on the risky situation indication scenario;

an actual information controller that controls a motion of actual information in an actual environment in which the vehicle travels based on the risky situation indication scenario; and

a superimposing unit that superimpose the virtual information on a predetermined position in the image shot by the imaging unit.

2. The vehicle risky situation reproducing apparatus according to claim 1, wherein the driving action detector detects the driving action of the driver based on information indicating a position and an attitude of the vehicle, information indicating a physical condition of the driver, information indicating a performance of the vehicle, and information indicating a condition surrounding the vehicle.

3. The vehicle risky situation reproducing apparatus according to claim 1 further comprising:

a driving action database that stores a carelessness action or a dangerous action while driving and a carelessness and danger level of the carelessness action or the dangerous action of the driver,

wherein the scenario generator generates the risky situation indication scenario based on the detection result of the driving action detector, the calculation result of the vehicle position and attitude calculation unit, and the carelessness and dangerous level store in the driving action database.

4. A method of operating the vehicle risky situation reproducing apparatus according to claim 1, comprising:

recording the driving action detected by the driving action detector and the present position and the driving direction of the vehicle calculated by the vehicle position and attitude calculation unit when the virtual information is displayed on the image display unit; and

reproducing the recorded driving action and the recorded current position and traveling direction of the vehicle.

5. The method according to claim 4, further comprising:

displaying an image shot by the imaging unit, including real information visually presented to the diver of the vehicle or an image shot by the imaging unit on which the virtual information is superimposed; and

displaying visual information regarding driving to the driver of the vehicle.

6. The vehicle risky situation reproducing apparatus according to claim 2 further comprising:

a driving action database that stores a carelessness action or a dangerous action while driving and a carelessness and danger level of the carelessness action or the dangerous action of the driver,

wherein the scenario generator generates the risky situation indication scenario based on the detection result of the driving action detector, the calculation result of the vehicle position and attitude calculation unit, and the carelessness and dangerous level stored in the driving action database.
