摘要： Method for switching the headlights of a vehicle from full beam to the dipped position and vice versa, said vehicle being provided with at least one image acquisition sensor facing in the direction in which the vehicle is travelling and suitable for detecting the presence of at least one second vehicle, comprising the steps of: a. acquiring by means of said at least one acquisition sensor one or more successive images having a plurality of chromatic shade levels; b. splitting each of said at least one or more images acquired into an array of cells, each cell of said array of cells being associated with an intensity value which corresponds to the chromatic shade level identified for said one or more images during step a) of the method; c. processing each cell of said array of cells to identify the presence of said at least one second vehicle; d. switching the position of the headlights from full beam to the dipped position according to the presence of said at least one second vehicle detected during step c) of the method; characterised in that step c) of the method comprises the step of: e. calculating for each array of cells one or more areas of greater intensity according to the maximum intensity value identified on at least one cell of said array of cells; f. calculating the relative distance between said two vehicles by comparing the areas of greater intensity identified during step e) of the method with one or more previously defined reference values.
摘要翻译：用于将车辆前灯从全光束切换到向下位置并且反之亦然的方法，所述车辆设置有至少一个图像获取传感器，所述图像获取传感器面向车辆行驶的方向并且适合于检测至少一个第二车辆，包括以下步骤：a。借助于所述至少一个获取传感器获取具有多个彩色阴影级别的一个或多个连续图像; 湾将获取的所述至少一个或多个图像中的每一个分割成单元阵列，所述单元阵列的每个单元与强度值相关联，该强度值对应于在步骤a）期间针对所述一个或多个图像识别的色度阴影级别方法; C。处理所述单元阵列的每个单元以识别所述至少一个第二车辆的存在; d。根据在所述方法的步骤c）期间检测到的所述至少一个第二车辆的存在，将所述前照灯的位置从全光束切换到所述下降位置; 其特征在于该方法的步骤c）包括以下步骤：e。根据在所述单元阵列的至少一个单元上识别的最大强度值，为每个单元阵列计算一个或多个强度更大的区域; F。通过比较在方法的步骤e）期间识别的较大强度的区域与一个或多个先前定义的参考值来计算所述两个车辆之间的相对距离。
