The invention discloses an active infrared vehicle-mounted night vision road condition detection and voice broadcast system. The visual effect and the sight distance of a driver are effectively improved under poor illumination conditions or at night. An active infrared technology is adopted, a semiconductor laser is used as an infrared light source, a high-definition CCD camera is matched to shootan infrared image video, median filtering, a Laplace operator, threshold segmentation and morphological processing are combined to preprocess the image video, and a YOLO algorithm is combined to recognize, classify and calibrate obstacles in front of a vehicle. Meanwhile, an infrared receiver loaded on a vehicle head is used for receiving reflected light of a front obstacle, distance measurementof the front obstacle is achieved, the dynamic distance of the front obstacle is obtained, if the front obstacle is detected, data are transmitted to a mobile phone APP through Bluetooth, voice broadcast prompt of the front obstacle and the distance of the front obstacle of the vehicle is achieved, and the driving safety coefficient is improved.

    本发明公开了一种主动红外车载夜视路况检测及语音播报系统,为了在光照条件差或夜晚环境下有效提高驾驶员视觉效果和视距,采用主动红外技术,使用半导体激光器作红外光源,配合高清CCD摄像机拍摄红外图像视频,并使用中值滤波,拉普拉斯算子和阈值分割与形态学处理结合对图像视频进行预处理,结合YOLO算法识别分类标定车辆前方障碍物。同时,利用装载在车头的红外接收器来接收前方障碍物的反射光,实现对前方障碍物的测距,获得其动态距离,假如检测到前方障碍物,则将数据通过蓝牙传输给手机APP,实现车辆前方障碍物及其距离的语音播报提示,提升行驶安全系数。
