Abstract: Disclosed is a method and apparatus for detecting and ranging cloud features. The method comprises: obtaining image data(e.g. using a camera (200); classifying, as a cloud feature, an image segment (502-508) of the image data; determining a plurality of moments of the image segment (502-508); using the determined plurality of moments, determining a geometric representation of that image segment (502-508); and, using the geometric representation, determining a distance between the cloud feature represented by that image segment (502-508) and an entity that obtained the image data.

Abstract: An optical apparatus to allow multiple fields of view in respect of an area of interest to be captured simultaneously. The apparatus has an optical input and an image sensor 24 defining a principle optical axis, wherein the input has a first optical unit and a plurality of focusing lenses lens0-lens5. The unit has a plurality of optical elements, at least one which is a refractive element such as a right angled prism lens (12, 14, 18 & 20, fig 3A) for refracting an optical beam through 90° and some may be cubic lenses (16, fig 3B). Each focusing lens is associated with a respective optical element to direct light onto the element. The focusing lens associated with the refractive element is configured to direct an optical beam onto the element at 90° to the principle optical axis, such that the refracted optical beam is parallel to the principle optical axis.

Abstract: A method of detecting at least one moving vehicle includes receiving (202) image data representing a sequence of image frames over time. The method further includes analyzing (204-206) the image data to identify potential moving vehicles, and comparing (208-212) at least one said potential moving vehicle with a vehicle movement model that defines a trajectory of a potential moving vehicle to determine whether the at least one potential moving vehicle conforms with the model.
