Method for detecting technical condition of highway

The invention relates to the technical field of pavement disease detection and discloses a method for detecting the technical condition of a highway. The method for detecting the technical condition of the highway comprises the following steps of a positioning step: a positioning processing unit of a detection system obtains the running distance of a vehicle-mounted device and generates real-timestake number information of the vehicle-mounted device according to highway information stored in a storage module; a disease displaying step: S1, a display module displays the stored display information according to a certain ratio in a narrowed manner; S2, a drawing and inputting processing unit of a processing module in the detection system draws and inputs shape information of diseases, and the display module displays the shape information of the diseases according to the same ratio in a narrowed manner; S3 an image processing unit of the processing module in the detection system processesthe drawn and input shape
