Information management system for constructional engineering

The invention relates to the technical field of image analysis, in particular to an information management system for constructional engineering, which comprises a memory and a processor, and the processor executes a computer program stored in the memory to realize the following steps: determining static and dynamic areas of each frame of image in a construction road aerial video, screening out adjacent frames of images of which the number of static feature matching point pairs of all static areas is smaller than a preset number; determining the degree of movement based on the screened target area and each dynamic area of the adjacent frame images; determining a registration score through the movement degree and the image features of each group of feature matching point pairs, and further determining an optimal feature matching point pair group; determining each optimal registration image through the optimal feature matching point pair group, and determining a construction road splicing image; the constructio
