Prisoner movement track screening method used for family interactive instruction and prisoner movement track screening system thereof

Abstract

The invention discloses a prisoner movement track screening method used for family interactive instruction and a prisoner movement track screening system thereof. The method comprises the following steps that step (1): positioning information capturing: the movement tracks of a prisoner are acquired; and the movement tracks are divided into multiple sub-tracks, the sub-tracks are screened to obtain effective sub-tracks, and the effective sub-tracks are stored; step (2): behavior log generation: the effective sub-tracks are matched with the position coordinates of all the places in the prison, and the summary behavior log of the prisoner is generated; and step (3): family interactive instruction display: a virtual reality video is manufactured by using the summary behavior log, and the virtual reality video is displayed. The method and the system have the advantages of ensuring the movement tracks to be accurate and effective by three-layer screening of the effective movement tracks.

Description

technical field [0001] The invention relates to a method and system for screening motion tracks of inmates used for family interaction and discipline. Background technique [0002] Due to the emotional depression and cramped environment of prison inmates after committing crimes, if effective discipline and counseling cannot be carried out, it is easy to cause inmates to have negative psychological problems and bring huge hidden dangers to prison safety management. However, it is limited to the natural barrier between inmates and prison management personnel and the mandatory isolation between inmates and their families, making it difficult for the family members of inmates to understand the real life conditions of inmates in prison, so that they cannot effectively provide psychological counseling and effective counseling for inmates. educate. [0003] With the advent of the mobile Internet era, intelligent wearable devices are also becoming popular, and various prison units ...

Problems solved by technology

However, due to the poor positioning accuracy of the current wearable devices under the local Internet of Things, the accuracy of motion trajectory screening is low, and the invalid motion trajectory becomes the noise data of motion trajectory analysis, which cannot be well eliminated. The noise data will inevitably affect the later motion trajectory analysis and movement. Trajectory utilization, it is impossible to do a good trajectory analysis based on the motion trajectory data, and generate images of prison life images of inmates through virtual reality technology, which makes it very difficult to discipline inmates.
