Correction method for suppressing the effects of scattered light on motor vehicle crash avoidance optical detection arrangements, whereby a correction value is derived from measurements with no obstacle present

摘要

Method for scattered light correction for use with an optical sensor arrangement, comprising transmitter and receiver, that is used for detection of obstacles within a monitoring region. According to the method when the reflected component of light generates a sample value and there is no object within the monitoring area, a correction value is determined from the sample value.
