Description

  The present invention relates to a vehicle driving education apparatus that can objectively confirm actual vehicle driving and is used for vehicle safe driving education.

Conventionally, there is a method of taking a video and observing the image when a third party is observing the driving situation of the own vehicle, particularly in relation to another vehicle.
When taking an image with a video camera, it is conceivable to mount the camera on a vehicle or fix it at a fixed point of the vehicle.
When a camera is mounted on a vehicle and imaged, the outside world with respect to the driving vehicle is imaged, and how the driving vehicle copes with the situation of the outside world is observed from the image.
Further, when the camera is fixed at a fixed point, an image of how the vehicle has dealt with when the vehicle encounters an event that occurs near the fixed point can be taken and the image can be observed.

However, when the camera is mounted on the vehicle and imaged, the situation of the outside world of the vehicle is imaged, and the reaction is judged based on the imaged situation of the outside world, which is not easy to judge.
In addition, when shooting a vehicle with a fixed-point camera, it is possible to capture the vehicle situation seen from a third party, but it is impossible to observe from a viewpoint other than the shooting location, and the camera shooting range Risk factors approaching from the outside cannot be explained, and there is a possibility that the pattern of the video used for learning may be limited. The driving operation of the educated person is also aware of the specific position (for example, a specific intersection) where the camera is installed As a result, the normal driving characteristics of the educated person may not be reproduced.
