The present invention discloses a night highway agglomerate fog automatic detection device on the basis of a laser and a detection method thereof. The detection method of the night highway agglomerate fog automatic detection device on the basis of the laser comprises: detection devices are installed at regular intervals on a highway, the cameras in the detection devices shoot images having a certain number of frames containing laser signals in adjacent detection devices, and an observation system is established; laser signal characteristics are automatically detected in different agglomerate fog concentrations, is established; in the process of detection, gray processing of the obtained images is performed, and the size of the real signal area and the average brightness value are calculated and taken as characteristics to find out corresponding agglomerate fog concentrations; and according to the final mapping relation of the laser signal characteristics and the agglomerate fog concentrations obtained by the previous step, the analysis of the agglomerate fog concentrations with respect to the data processed at present is performed, the result is recorded, and information is published or an early warning is given according to the setting condition. According to the invention, the detection device is cost effective, energy efficient and economical and practical, and has improved efficiency; and the system has good anti-interference effect and high stability.
