The invention relates to the field of realizing traffic sign projection display through a microlens array, and relates to a traffic sign projection system based on the microlens array. Comprising a camera, an image processing system, a light source control system and an imaging system, the camera collects image data and inputs the image data into the image processing system, the image processing system outputs a traffic sign recognition result and sends information to the light source control system, and the light source control system receives the information, executes an instruction, displays a traffic sign pattern and projects a traffic sign to the ground in front of an automobile through the imaging system; the traffic information can be quickly transmitted to a driver, the problem possibly caused by the fact that the driver has no time to check the road sign during driving or the attention is distracted when checking the traffic sign is solved, convenient driving instructions are provided, and driving safety is guaranteed.

    本发明涉及通过微透镜阵列实现交通标志投影显示领域,涉及一种基于微透镜阵列的交通标志投影系统。包括摄像头,图像处理系统,光源控制系统和成像系统;摄像头收集图像数据,并将图像数据输入图像处理系统,图像处理系统输出交通标志识别结果,发送信息至光源控制系统,光源控制系统接收信息并执行指令,显示交通标志图案,通过成像系统将交通标志投影至汽车前方地面;本发明可快速将交通信息传递给驾驶员,解决了驾驶员行车时无暇查看路标,或查看交通标志分散注意力所可能引发的问题,提供了便捷的行车指示,保障行车安全。
