Mobile terminal track data denoising method and device

Abstract

The invention provides a denoising method and device for mobile terminal trajectory data. The method comprises the steps: obtaining trajectory data including a first position, a second position, a third position and corresponding time based on each piece of mobile terminal trajectory data; performing calculating to obtain a first distance, a second distance, a third distance, a first time and a second time; recording the first track data of which the first time and the second time are less than the set duration, temporarily confirming the noise data of which the first time and / or the second time are / is not less than the set duration, and recording the noise data as second track data; performing calculating to obtain a second position included angle and first, second and third speeds; temporarily determining the first track data as noise data and recording the noise data as third track data under the condition that the acquired data judges that the first track data meets the noise filtering condition; and judging whether the second position and the third position are equal or not for each piece of track data in the second track data and the third track data: if yes, determining thedata as noise data, and removing the corresponding mobile terminal track data. According to the scheme, the purpose of denoising the track of the mobile terminal can be achieved.

Description

technical field [0001] The invention relates to the fields of communication technology and information processing technology, in particular to a method and device for denoising trajectory data of a mobile terminal. Background technique [0002] With the continuous advancement of my country's communication network construction, my country's mobile users continue to grow. When users communicate through mobile terminals, a large amount of communication data is generated. The data records information such as the base station connected to the user's communication, and the time at the same time. At present, there are a large number of pilot areas for 5G network signals across the country. The ideal coverage range of 5G base station signals is 250 meters. In complex urban communication environments, the coverage distance is shorter. Base station location + communication time, to represent the mobile terminal trajectory of the terminal user's travel details, is getting closer and cl...
