The invention relates to a roadside rushing-out object warning method based on light-emitting marking lines. The method comprises the following steps: acquiring video data and delimiting a region of interest; comparing two adjacent video frame images in the region of interest according to a preset frame rate; in response to the difference between the two video frame images, judging whether the difference is a shadow or not; in response to the fact that the difference is not a shadow, the difference between the two video frame images is a moving object; judging whether the moving object is a rushing-out object or not; in response to the fact that the moving object is a rushing-out object, the motion state of the rushing-out object is sent to the light-emitting marking equipment, the motion state of the rushing-out object comprises a high speed and a low speed, and if the rushing-out object is the low-speed rushing-out object, the color of the light-emitting marking equipment becomes a first preset color and does not flicker; and if the rushed object is a rapid rushed object, the color of the light-emitting marking equipment is changed into a preset color II and flickers at a preset frequency. Therefore, rushing-out objects in the sight blind area of the driver can be detected, and the driver is warned of rushing-out of the objects through the light-emitting marking lines.
本发明涉及一种基于发光标线的路侧冲出物体警示方法,包括获取视频数据并划定兴趣区域;根据预设帧率对兴趣区域中相邻两个视频帧图像进行比较;响应于两视频帧图像存在差异,判断差异是否为影子;响应于差异不是影子,得到两视频帧图像存在的差异为移动物体;判断移动物体是否为冲出物体;响应于移动物体为冲出物体,将冲出物体的运动状态发送至发光标线设备,冲出物体的运动状态包括快速和慢速,若冲出物体为慢速冲出物体,发光标线设备颜色变为预设颜色一且不闪烁;若冲出物体为快速冲出物体,发光标线设备颜色变为预设颜色二且在预设频率下闪烁。由此,能够对驾驶员视线盲区内的冲出物体进行检测并通过发光标线警示驾驶员有物体冲出。
