BigData Fusion for Trajectory Prediction of Multi-Sensor Surveillance Information Systems.

Video surveillance information systems assist forensics to examine and analyze the evidence from crime scenes to develop objective findings in the investigation of crime. Often, the existing surveillance information systems exploit an array of security cameras and IoT devices monitoring the same crime scene from different points of view while the crime unfolds over a range of time. However, none can automatically and selectively merge big data streams connected to such systems to provide a holistic, end-to-end safety picture.This work proposes a trajectory prediction architecture framework within a multi-sensor surveillance system. We developed a novel position measurement technique using monocular depth perception networks with multi-camera setup using triangulation. We tested and compared our technique with a single camera sensor in our first experiment and as the multi-camera setup determines the position of our target more accurately, we used our measurement function in our second experiment. In our second experiment, we employed the Unscented Kalman Filter (UKF) for predicting the trajectory of the target, and proved that UKF has good potential for being used in surveillance systems. Lastly, we designed a general architecture framework for big data analysis in multi-sensor surveillance systems consisting the four layers: the Sensor Layer, the Single Sensor Computation Layer, the Data Fusion and Interpretation Layer, and the Human Interaction Layer.
