Acquisition and tracking method and apparatus

The present disclosure relates to a target object tracking system for a vehicle. The target object tracking system includes a processor for receiving image data captured by one or more sensor disposed on the vehicle. The processor is configured to analyse the image data to identify image components IMC(1-3) and to determine a movement vector V(1-3) of each image component IMC(1-3). A first set of components having a first movement vector is formed and these are classified as non-target image components while a second set of component(s) having a different movement vector is formed and classified as target image components and using this set to acquire the target object with the target object being acquired in dependence on the components of the second set.
