Abstract:
Present disclosure provides a travel assistance device which comprises: a road detection unit that obtains an infrared image in front of a vehicle from an infrared imaging unit that is mounted on the vehicle, and detects a road end line of a road on which the vehicle travels from the captured infrared image; a division line detection unit that obtains a visible image in a range corresponding to a range indicated by the infrared image from a visible imaging unit that is mounted on the vehicle, and detects a division line of the road from the captured visible image; an image generation unit that generates an integrated image indicating the road end line and the division line on the basis of the infrared image and the visible image registered with each other; and a division line estimation unit.

Claim (Index 4):
The travel assistance device according to  claim 1 ,\n wherein the image generation unit generates a second integrated image which is a two-dimensional image indicating the road end line and the division line as the integrated image on the basis of the infrared image and the visible image registered with each other, and the division line estimation unit performs a second estimation process of calculating respective candidate points of the division lines corresponding to the respective points of the road end lines according to a condition that a distance in the horizontal direction between the road end line and the division line increases at a constant ratio as a distance in a vertical direction from an upper end of the road end line increases in the second integrated image in a state in which the second integrated image is arranged with a downward direction of the vehicle set as a downward direction of the image, and estimating the extended portion of the division line on the basis of the calculated candidate points of the division lines.
