    • Disclosed are an apparatus and a method for normalizing an image of a driver's face in a predetermined size on the center of a monitor by automatically controlling a lens when the image of the driver's face is detected. The apparatus includes a lens for photographing a driver's face, a first motor for moving the lens in a forward or rearward direction in order to adjust a zoom parameter, a second motor for moving the lens in a horizontal or vertical direction in order to adjust a pan parameter or a tilt parameter, and a controller for extracting an initial face area from a photographed image and controlling operations of the first motor and the second motor according to the extracted initial face area.
    • 公开了一种在检测到驾驶者的脸部的图像时通过自动控制镜片来将显示器中心的驾驶员脸部图像标准化为正常化的装置和方法。 该装置包括用于拍摄驾驶员脸部的镜头,用于向前或向后方向移动透镜以调节变焦参数的第一电动机,用于在水平或垂直方向上移动透镜的第二电动机,以便调整 平移参数或倾斜参数,以及控制器,用于从拍摄图像中提取初始面部区域,并根据所提取的初始脸部区域来控制第一电动机和第二电动机的操作。

    • Provided is a vehicle detection/tracking device that allows vehicle detection and then tracking using a camera focusing around a camera-mounted vehicle. To this end, an optical flow is acquired from video data input through a camera mounted in a vehicle during driving of the vehicle. A background optical flow, an optical flow generated by driving the vehicle, is acquired. The acquired optical flow and the acquired background optical flow are compared, and a vehicle candidate area is detected through an optical flow for an object around the vehicle. In particular, template matching is performed on the vehicle candidate area for vehicle detection and a detected vehicle can be tracked by continuously comparing the detected optical flow and the background optical flow.
    • 提供了一种车辆检测/跟踪装置,其允许车辆检测然后使用照相机安装的车辆周围的照相机进行跟踪。 为此,在车辆驾驶期间通过安装在车辆中的照相机输入的视频数据获取光流。 获得背景光流,通过驾驶车辆产生的光流。 获取的光流和所获取的背景光流被比较,并且通过用于车辆周围的物体的光流来检测车辆候选区域。 特别地,对于用于车辆检测的车辆候补区域进行模板匹配,并且可以通过连续地比较检测到的光流和背景光流来跟踪检测到的车辆。
