Travel assistance device and computer program

Abstract

Provided are a travel assistance device and a computer program which enable travel assistance which is appropriate for connection roads to be performed. More specifically, the present invention is configured such that a captured image of the surrounding environment of a vehicle is acquired, a map information image, i.e. a map image which expresses a map in three dimensions, and shows the same range as the image-capture range of the captured image from the same direction as the image-capture direction of the captured image, is acquired, the driver visibility of a connection road, i.e. a road which connects with the road along which the vehicle is travelling at a junction point present in the surroundings of the vehicle, is determined on the basis of the captured image and the map information image, and a visibility determination result is outputted.

Description

technical field [0001] The present invention relates to a driving assistance device and a computer program for assisting driving of a vehicle. Background technique [0002] In recent years, for example, as one of driving assistance for vehicles, risk factors around a moving body are determined, and communication and vehicle control based on the determination results are performed. The so-called risk factor is a factor that should be paid attention to when the mobile body is running. In particular, one of the risk factors is a road connected to a road on which the vehicle travels at a branch point around the vehicle (hereinafter referred to as a connecting road). . A connecting road is a road on which other vehicles, pedestrians, bicycles, etc. moving on the road may enter the road on which the vehicle travels in the future. Therefore, it is very important for the driver to grasp the existence of the connecting road in order to pay attention in advance to the entry of such ...

Problems solved by technology

[0005] However, in the above-mentioned Patent Document 1, the blind spot area is determined from a bird's-eye view based on the positional relationship between the own vehicle and other vehicles, but since the surrounding environment that the driver can actually visually recognize is not considered, there are differences between the area determined to be the blind spot area and the actual area. Situations where the driver's dead zone is different

Therefore, there is a possibility that connecting roads that are not actually included in the dead-spot area are also judged as risk factors and become assistance targets.
