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. |

1. In a surveillance system including a remote sensor apparatus for collecting data and a portable receiver for receiving data collected by at least one sensor installed in the remote sensor apparatus, wherein the portable receiver is capable of running an application program for processing the received data and displaying the processed data on a display screen of the portable receiver, wherein the remote sensor apparatus has a spherical housing for containing a processing unit, a plurality of image sensors coupled to the processor and a wireless transceiver and wherein each of the plurality of image sensors is fitted with a wide-angle lens, a method for generating a panoramic view of a scene external to the housing of the remote sensor apparatus, the method comprising:
receiving, at the portable receiver, first image data collected simultaneously from the plurality of image sensors installed in the remote sensor apparatus, wherein the received first image data includes a first plurality of images captured by the plurality of image sensors that are located in fixed positions relative to one another; processing, at the portable receiver, the first 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, wherein the areas of field of view are determined by positions of the plurality of image sensors and a field of view of the wide-angle lens fitted with each of the plurality of image sensors; and generating a panoramic view by blending the processed first plurality of captured images. |
