The invention provides a driving safety auxiliary device based on visual analysis. The driving safety auxiliary device comprises a visual sensor unit, an image analysis unit, a processing unit and analarm unit which are connected in sequence. The visual sensor unit is arranged right in front of a vehicle and used for collecting road image information in front of the vehicle; the image analysis unit is used for calculating the distance between the vehicle and the front vehicle according to the road image information; and the processing unit is used for calculating the relative speed accordingto the distance variation with the front vehicle, calculating the potential collision time according to the relative speed and the distance between the current vehicle and the front vehicle, and controlling the alarm unit to send out alarm information when the potential collision time is smaller than a set threshold value. According to the invention, the defects of inattention or insufficient experience and the like of a driver are overcome, the potential collision danger is adaptively reminded, and the vehicle driving safety is improved.

    本发明提供一种基于视觉分析的驾驶安全辅助装置,包括:依次连接的视觉传感器单元、图像分析单元、处理单元和警报单元;其中视觉传感器单元设置在车辆正前方,用于采集车辆前方的道路图像信息;图像分析单元,用于根据道路图像信息计算车辆与前方车辆之间的距离;处理单元,用于根据与前方车辆之间的距离变化量计算相对速度,并根据相对速度和当前车辆与前方车辆之间的距离计算潜在碰撞时间,当潜在碰撞时间小于设定的阈值时,控制警报单元发出警报信息。本申请有助于弥补驾驶员注意力不集中或者经验不足等缺陷,对潜在的碰撞危险进行自适应提醒,提高了车辆驾驶的安全性。
