Abstract: A method is provided for a surveillance system including a remote sensor apparatus a portable receiver. The method includes receiving, at the portable receiver, image data collected simultaneously from a plurality of image sensors installed in the remote sensor apparatus. The method also includes processing, at the portable receiver, the received image data by, for each of the first plurality of captured images, detecting image features and performing feature matches by matching control points across neighboring images based on a control-point assumption that the control points are relevant only in areas of field of view overlap. The areas of field of view are determined by positions of the plurality of image sensors and a field of view of a wide-angle lens fitted with each of the plurality of image sensors. The method further includes generating a panoramic view by blending the processed first plurality of captured images.

Abstract: In a surveillance system including a remote sensor apparatus and a portable receiver, a method is provided for collecting and processing data related to a surrounding environment of the remote sensor apparatus including image data for a scene external to the housing of the apparatus. The method includes receiving, at the processing unit, raw image data simultaneously from a plurality of image sensors as the raw image data is being captured by the plurality of image sensors. One or more light sources are placed around a wide-angle lens fitted to each of the image sensor. Infrared or near-infrared light emanating from the plurality of light sources is used in a dark environment. The method also includes processing, at the processing unit, the simultaneously received raw image data to generate pre-processed image data. The method further includes transmitting the pre-processed image data to the portable receiver using the wireless transceiver.
