This report describes the activities and outcomes of a project initiated to develop a panoramic imager -- consisting of a 360-degree mirror in a clear housing with a color camera aimed at the mirror -- that can improve the current video camera systems used in patrol cars, most of which only record the activity in front of the vehicle.
The overall objective of this Phase I effort was to demonstrate the enhanced capabilities of a 360-degree panoramic imager and evaluate how this tool can be used in the field. The Phase I work focused on the development of a prototype 360-degree panoramic imager, the integration of the imager into a police car, the development of the image-processing software, and testing of the resulting prototype. These objectives were achieved. Under field conditions, the panoramic imager demonstrated its ability to view the entire surroundings of a police vehicle simultaneously; mounting it in a vehicle proved to be easily achievable. The panoramic imager consists of four main parts: the parabolic mirror, video camera, housing, and associated software. The software for the project performs three main functions: displaying the live video feed from the camera, saving the video to a movie, and remapping the live video feed. In addition to producing knowledge about how a panoramic imager can be used in law enforcement, the project identified modifications that must be made in order to build a second, police-car-ready prototype, as well as the technologies that must mature in order to achieve a large-scale application of the 360-degree imager in law enforcement.
