Embodiment Construction

[0030] A traffic lane recognition device according to an embodiment of the present invention includes a camera, a boundary marking detection unit, and a traffic lane recognition unit.

[0031] The camera continuously shoots the front area, the rear area, or the left and right areas of the vehicle driving in the lane. Through the continuous shooting of the camera, a plurality of consecutive captured images that change with the movement of the traveling vehicle can be obtained. For example, when shooting with a camera at a frame rate of 24fps to 60fps (frame per second: frame per second) for about 3 to 5 seconds, it is possible to obtain continuous 72 to 300 captured images. In addition, it is preferable that each captured image obtained by shooting by the camera includes, for example, the lane where the vehicle is running, the lane on the right side of the lane where the vehicle is running, and the lane to the left of the lane where the vehicle is running. The lane on the sid...

Abstract

The invention performs high-precision recognition on a lane with driving vehicles through a lane image which is photographed by a camera. A travelling lane recognition apparatus (11) comprises the components of a camera (12) which photographs a rear area of the vehicle; a lane line detection unit (15) which detects the lane line by means of the image that is obtained by the camera; and a travelling line recognition unit (16) which recognizes the lane line where the vehicles drive by means of the detected lane line. The lane line detection unit respectively extracts the detection object image from multiple images which are continuously photographed, and recognizes a linear mark position with a linear mark in each detection object image, and performs repeated processing of detecting a whiteline or a blank according to an image photographing time sequence, thereby determining a fact that the lane line is a full line or a dotted line. The travelling line recognition unit recognizes the lane on which the vehicle travels according to the position relation between the full lane line and the vehicle or the position relation between the dotted lane line and the vehicle.

Description

technical field [0001] The present invention relates to a traffic lane recognition device, a traffic lane recognition method, and a program for recognizing a lane in which a vehicle is running among a plurality of lanes of a lane. Background technique [0002] In an autonomous vehicle, it is controlled in response to the increase or decrease of lanes in the driving lane, or the branching or merging of lanes at intersections (Japanese: Interchange) or intersections To drive the vehicle, it is necessary to identify the lane the vehicle is driving from among the multiple lanes in the lane. [0003] As a vehicle lane recognition technology, a technique is known in which the position of the vehicle is estimated by utilizing a high-precision GPS (Global Positioning System) mounted on the vehicle, and the position of the vehicle is associated with a high-precision map, Thereby identifying the lane that the vehicle is driving on. In addition, there is known a technique for recogni...
