Summary:The invention relates to a non-motor vehicle trajectory reconstruction method for a non-motor vehicle shared space. The method comprises the following steps: extracting an initial trajectory through a CV algorithm; lSTM is adopted to predict and complement a trajectory missing due to shielding, and the trajectory before and after shielding is matched through a Hungary algorithm to complement a complete trajectory; and carrying out noise reduction on the complemented complete track by adopting a three-layer circulation social force particle filtering algorithm constructed by integrating a social force model representing a non-motor vehicle driving behavior into a particle filtering framework to obtain a reconstructed track. Compared with the prior art, the method has the advantages that the performance of acquiring high-precision trajectory data by a video detector is effectively improved, finer sensing data is provided for holographic intersections and traffic control systems, and the method has high applicat
