Abstract:
A signal processing method for a vehicle navigational system having a radar arrangement and an image sensor arrangement, the method including the steps of:monitoring a solid-angle region with the radar arrangement; monitoring essentially the same solid-angle region with the image sensor arrangement; determining respective target parameters from the signals received from the radar arrangement and the image sensor arrangement; linking the target parameters determined from signals received from the radar arrangement with the target parameters determined from signals received from the image sensor arrangement through data merging wherein reduced data sets and the resultant derived target parameters are created during the evaluation of the signals received from the radar and image sensor arrangements through a suitable linking of the data; specifying solid angle sections for an image evaluation based on the evaluation of the signals received from the radar arrangement; and evaluating the signals received from the image sensor arrangement solely from these specified solid angle sections.
