In general, women and novice drivers have considerable difficulties when parking in parking lots and in some cases cause contact accidents. Of course, the same is true for experienced drivers.

In order to park a vehicle in a parking space, it is necessary to quickly determine the current position of the vehicle, the distance to the feature around the parking space, the steering angle, the expected course of the vehicle, etc. based on the driver's sense and experience.

Therefore, when a vehicle is parked in a narrow space and a blind spot, the driver may cause a collision with another vehicle or an obstacle due to the driver's momentary positioning error or an operation mistake, resulting in economic loss or heavy pressure on the driver's parking. Can cause.

One way to solve this problem is to equip the front and rear cameras and transmit the front and rear images of the vehicle to the monitor installed in the driver's seat during the parking process, helping the driver to recognize the current parking process. In order to increase the number of accidents and prevent accidents, a system has been developed. At present, the parking assistance system has been further developed to develop a parking aid system based on a top view.
