PROBLEM TO BE SOLVED: To provide an inter-vehicle distance alarm device and a collision alarm device that shorten a time required for information processing, prevent rear-end collision accidents, and notify a driver of a collision with obstacles by an alarm to allow the collision to be obviated.SOLUTION: An inter-vehicle alarm device and a collision alarm device comprise imaging means 1, image recognition means 2, inter-vehicle distance determination means 3, stationary object determination means 4 and moving object determination means 5. The image recognition means 2 is configured to replace an image of an object of a prescribed width in upper and lower directions from a center point of an image signal with hue, saturation and luminance, and give the object a sequential number in order from the center point to a horizontal direction by the hue and saturation to identify the object. The inter-vehicle distance determination means 3, the stationary object determination means 4 and the moving object determination means 5 are configured to: make a measurement from the image for the identified object; calculate a distance between a self-vehicle 30 and the identified object in order; detect a speed of the self-vehicle 30 to calculate a time until the self-vehicle 30 reaches the object; and when an arrival time falls within a prescribed time, set off an alarm.SELECTED DRAWING: Figure 1

    【課題】情報処理の時間が短く、追突事故を防止し、障害物との衝突を警報で知らせて、衝突を未然に回避することができる車間距離警報及び衝突警報装置を提供する。【解決手段】車間距離警報及び衝突警報装置は、撮像手段1、画像認識手段2、車間距離判定手段3、静止物判断手段4及び移動物判断手段5を有する。画像認識手段2は、画像信号の中心点から上下方向の所定幅の対象物の画像について、色相、彩度及び輝度に交換し、色相と彩度により中心点から水平方向に順に対象物について連番を付して識別する。車間距離判定手段3、静止物判断手段4及び移動物判断手段5は、識別した対象物について、画像から計測して、自己車両30と識別した対象物との距離を順に算出する。自己車両30の速度を検出して、自己車両30が対象物まで到達する時間を計算し、到達時間が所定の時間以内の場合には、警報を発する。【選択図】図1
