The invention discloses an omnibearing automatic driving collision early warning method and system based on vision and communication, and relates to the technical field of computers.The method comprises the steps that a target in an image is detected through video data collected by an automobile data recorder; the target center position of two continuous frames is output through a target detection algorithm, the target detection algorithm adopts a Kalman filtering algorithm, and the center point of the target detection algorithm is tracked; converting the RSSI value into a target actual distance value by using a staged logarithm fitting technology; performing noise filtering on the collected MAC addresses of all the intelligent terminals; performing data sample expansion processing on the information subjected to the MAC address noise filtering; and designing an early warning strategy based on visual information captured by the camera. According to the invention, the visual information and the communication information are effectively fused, so that the problems of low distance measurement speed and poor robustness caused by dependence on the visual information and low distance measurement precision and poor stability caused by dependence on the communication information can be effectively solved.
