The invention relates to a method for judging whether a vehicle running on a main lane of an expressway or an elevated road enters a ramp or not, and the method comprises the following steps: collecting scene data, and collecting a surrounding scene of the vehicle running on the expressway or the elevated road through image collection equipment; making feature comparison: processing the acquired images and comparing features obtained after processing with ramp features stored in a database; calculating credibility, and calculating the credibility through feature comparison according to weighted calculation of each feature and the priority level of each feature; when the obtained credibility is greater than 50%, judging that the vehicle enters the ramp; and when the obtained credibility isless than 50%, judging that the vehicle runs on the main lane. The invention also relates to a device for executing the method.
本发明涉及一种用于判断在高速公路或高架路主道上行驶的车辆是否进入匝道的方法,所述方法包括以下步骤:采集场景数据,通过图像采集设备对在高速公路或高架路上行驶的车辆的周边场景进行采集;特征对比,将采集到的图像进行处理并且将处理后得到的特征与数据库中存储的匝道特征相比较;计算可信度,通过特征对比,根据对每个特征进行加权计算以及各个特征的优先级别计算出可信度;在得出的可信度大于50%时,判断车辆进入匝道;在得出的可信度小于50%时,判断车辆在主道上行驶。本发明还涉及用于实施该方法的装置。
