Vehicle operation assisting device

Takahashi Yasushi

- 27 Jun 2003

TL;DR: In this article, the authors proposed a method to estimate the advancing route of a vehicle even when a white line on a road is difficult to recognize, by filtering the offset quantity of the vehicle traveling aside from the traveling route and calculating the difference between the vehicle advancing route and the passing position.

Vehicle traveling lane picture processor

Shigeto Nakayama, +1 more

- 12 Jul 1994

TL;DR: In this paper, a picture processing inhibition area is set on image-picked up picture data on the basis of the position information of the obstacle, and besides, the picture data located outside the picture processing means is processed by picture processing and information a traveling lane shows is outputted, even though the obstacle such as the front running vehicle entered the field of view of the CCD camera 10, it never overlaps the processing area, and therefore, the traveling lane recognition is never mistaken.
