Detection code matching processing method and graph code joint detection system

The invention provides a detection code matching processing method and a graph code joint detection system. The detection code matching processing method comprises the following steps: A1, extractinga plurality of second characteristic values associated with a first characteristic value from an archive library; A2, according to a preset time period, performing duplicate removal processing according to the collision condition of each second characteristic value at each monitoring station, obtaining the collision frequency of each second characteristic value after duplicate removal, and recording the collision frequency as a real collision frequency; step A3, respectively processing according to the real collision times to obtain a matching rate of each second characteristic value to the first characteristic value; and step A4, taking the matching rates of all the second feature values as final matching results of the first feature value and storing the final matching results in an archive library.
