To provide a partition line detector which can improved in accuracy of detecting a lane partition line shown on a road.SOLUTION: The partition line detector comprises: a confidence degree calculation unit 31 which, by inputting an image obtained by an imaging unit 2 mounted in a vehicle 10, calculates, for each pixel of the image, the degree of confidence that the object seen in the pixel is a lane partition line and the degree of confidence that the object is an other object; a correction area setting unit 32 which, when the vehicle 10 changes lanes, sets a correction area to a range of the image in which a lane partition line is assumed to be included; a correction unit 33 for correcting, for each pixel included in the correction area, the degree of confidence of being a lane partition line or the degree of confidence of being another object so that the degree of confidence of being the lane partition line is relatively higher than the degree of confidence of being the other object; and a partition line detection unit 34 for detecting a pixel, of the pixels of the image, in which the degree of confidence of being the lane partition line is higher than the degree of confidence of being the other object, and detecting a straight line composed of a row of the detected pixels as the lane partition line.SELECTED DRAWING: Figure 3
【課題】道路上に表示された車線区画線の検出精度を向上できる区画線検出装置を提供する。【解決手段】区画線検出装置は、車両10に搭載された撮像部2により得られた画像を識別器に入力することで、画像の画素ごとに、その画素に写っている物体が車線区画線である確信度及び他の物体である確信度を算出する確信度算出部31と、車両10が車線変更するときに、画像のうちの車線区画線が含まれると想定される範囲に補正領域を設定する補正領域設定部32と、補正領域に含まれる各画素について、車線区画線である確信度または他の物体である確信度を、車線区画線である確信度が他の物体である確信度に対して相対的に高くなるよう補正する補正部33と、画像の各画素のうち、車線区画線である確信度が他の物体である確信度よりも高い画素を検出し、検出した画素が並ぶ直線を車線区画線として検出する区画線検出部34とを有する。【選択図】図3
