Automotive system with motion detection capabilities

Abstract:

A car may be equipped with a camera for detecting the movement of objects in the vicinity of the car. The camera may be used to capture a series of images. A number of target sample points may be defined in each image. The position of the target sample points may corresponding to the driver's blind spot or other region(s) of interest. The camera may also include separate filters for generating a long term pixel intensity output and a short term pixel intensity output at each of the target sample points. These long and short term average outputs may be compared to determine if a large change in intensity has occurred over a short period of time. The order of target activation can then be used to determine the direction of vehicle motion while filtering out noise or other road markings.
