Multi-source data fusion method and device and electronic equipment

The invention provides a multi-source data fusion method and device and electronic equipment, and the method comprises the steps: extracting a target field in multi-source heterogeneous data, the multi-source heterogeneous data comprising one or more fields; preprocessing the multi-source heterogeneous data based on the target field; converting the preprocessed multi-source heterogeneous data into a data format of a graph data structure to obtain multi-source data with a uniform format; and associating the multi-source data by adopting a multi-source data association algorithm based on adaptive constraint relaxation to realize fusion of the multi-source data so as to realize track association. According to the method, the multi-source heterogeneous data is represented by using the graph data structure to form a uniform data format, so that the difficulty in association and fusion between different source data is reduced, and the problem that the difficulty in association and fusion between different source da
