The invention discloses a signal lamp color processing method and device, relates to the field of computer image processing, and is used for unifying signal lamp image colors and improving the accuracy of judging a red light running event. The method comprises the following steps: acquiring hue value distribution information of a plurality of target signal lamp areas in at least one image, wherein the plurality of target signal lamp areas are other signal lamp areas except a green signal lamp area in the plurality of signal lamp areas; determining a red-yellow segmentation threshold based on the distribution information; wherein the red-yellow segmentation threshold value is used for distinguishing a red hue value and a yellow hue value; determining a red signal lamp area and a yellow signal lamp area in the plurality of target signal lamp areas based on a red-yellow segmentation threshold; adjusting the hue value of the red signal lamp area from the first current value to a first target value, and adjusting the hue value of the yellow signal lamp area from the second current value to a second target value; wherein the first target value belongs to a red hue value distribution range, and the second target value belongs to a yellow hue value distribution range.
本申请公开了一种信号灯色彩的处理方法及设备,涉及计算机图像处理领域,用于统一信号灯图像色彩,提升判断闯红灯事件准确率。该方法包括:获取至少一个图像中的多个目标信号灯区域的色调值分布信息,该多个目标信号灯区域是多个信号灯区域中的绿色信号灯区域之外的其他信号灯区域;基于分布信息确定红黄分割阈值;其中,红黄分割阈值用于区分红色色调值和黄色色调值;基于红黄分割阈值,确定多个目标信号灯区域中的红色信号灯区域和黄色信号灯区域;将红色信号灯区域的色调值由第一当前值调整为第一目标值,将黄色信号灯区域的色调值由第二当前值调整为第二目标值;其中,第一目标值属于红色色调值分布范围,第二目标值属于黄色色调值分布范围。
