Abstract: A cross road guiding apparatus and method of car navigation are provided to use a camera to obtain information of traffic facilities at a complex cross road, where is not easy to receive GPS(Global Positioning System) information. A cross road guiding apparatus includes an image input unit(200), an image output unit(210), a GPS receiving unit(220), a navigation information unit(230), an image recognizing unit(240), a cross road checking unit(250), a cross road center checking unit(260), a direction indicating unit(270), and a control unit(280). The image recognizing unit recognizes traffic facilities from a front image of a car. The cross road checking unit determines whether the car approaches the cross road by using GPS location information on the car and cross road included in the navigation information. The cross road center checking unit checks the center point of the cross road from the front image of the car as the car approaches the cross road. The control unit reflects the distance between the current location of the car to the center point of the cross road in turn-by-turn information. The direction indicating unit overlaps the front image of the car with the turn-by-turn information.
Abstract translation: 提供一种交叉道路导引装置和汽车导航方法，以使用相机来获得不容易接收GPS（全球定位系统）信息的复杂十字路口的交通设施的信息。 十字路引导装置包括图像输入单元（200），图像输出单元（210），GPS接收单元（220），导航信息单元（230），图像识别单元（240），十字路口检查 单元（250），十字路口中心检查单元（260），方向指示单元（270）和控制单元（280）。 图像识别单元从汽车的前方图像识别交通设施。 十字路口检查单元通过使用包括在导航信息中的汽车和十字路上的GPS位置信息来确定汽车是否接近十字路口。 十字路口中心检查机构在车辆靠近十字路口时，从汽车的前方图像检查十字路口的中心点。 控制单元反映车辆的当前位置与十字路口的中心点之间的距离。 方向指示单元与转弯信息重叠汽车的前方图像。

Abstract: A method and an apparatus for displaying a traffic lane in a car navigation device using a camera are provided to improve readability of the car navigation device by displaying a semi-actual lane image to a driver. An apparatus for displaying a traffic lane in a car navigation device includes an image input unit(10), a lane recognition unit(20), an image output unit(60), an image display unit(50), an angle calculator(30) and a determining unit(40). The image display unit applies a lane separation line, which is recognized by the lane recognition unit, on a forward image, which is taken by the image input unit, or extracts a previous frame image, such that a driving image is inserted into the image, from which the lane separation line is extracted, or the previous frame image. The angle calculator calculates an angle between two lane separation lines. The determining unit compares the calculated angle with a threshold value, and controls the image display unit to apply the lane separation line on the image, when the calculated angle is smaller than the threshold value.
