Multi-source trajectory information fusion and compression method

The invention discloses a multi-source track information fusion and compression method, and relates to the field of data processing. According to the invention, a smooth analysis thought is adopted, and real-time denoising is carried out on each positioning terminal track through adaptive calculation of angle and speed error threshold values; calculating the data quality of each track in the window time in real time; adaptively calculating the weight of each track according to the track data quality, proposing an improved exponential weighted average algorithm, and calculating the weighted average value of the longitude and latitude of the multi-source track points as a fused track coordinate; and calculating the roughness of the fused trajectory in the sliding time window, dynamically and adaptively adjusting the sub-block size of the GeoHash algorithm according to the roughness of the trajectory, and realizing efficient real-time compression on the premise of keeping high compression precision.
