Police unmanned aerial vehicle big data acquisition system and crime spatial database construction method

Abstract

The invention provides a police unmanned aerial vehicle big data acquisition system, comprising an unmanned aerial vehicle, a camera module used to obtain video information, a WIFI signal acquisition module, a base station simulator used to search phone cards and position information, an unmanned aerial vehicle remote controller, and a database server. The base station simulator comprises a simulator host, and a background control unit. The camera module, the WIFI signal acquisition module, and the simulator host are installed on the unmanned aerial vehicle. The simulator host is dynamically connected with the background control unit through WIFI, and transmits data in real time. The police unmanned aerial vehicle big data acquisition system uses the unmanned aerial vehicle, the camera module, the WIFI signal acquisition module, and the base station simulator module to give full play to three-dimensional spatial motion capability, so as to obtain videos, networks, and mobile phones and other multisource information from higher positions, more flexible angles, closer distances, and in a more hidden method. The invention also provides a crime spatial database construction method.

Description

technical field [0001] The invention relates to the technical field of police drones, in particular to a multi-source big data police drone big data acquisition system and a method for constructing a crime space database. Background technique [0002] At present, police video law enforcement vehicles generally adopt high-definition cameras and mobile data transmission methods to collect dynamic traffic flow information and search for illegal and criminal data. But this kind of video law enforcement vehicle has the following defects: one, space limitation, due to the ground traffic dependence of the vehicle, it has driving obstacles, and the range of space activities is greatly restricted, so that it cannot be used from a higher position and more flexibly. Obtain multi-source information such as video, network and mobile phone in a more accurate angle, closer distance, and more covert way. Second, the data collection function is relatively single, limited to video informatio...
