Abstract:
1. An identical object determination method of determining whether or not objects detected by a plurality of sensors are identical, the identical object determination method comprising: a first step for determining a relative position and relative speed of each of the detected objects; a second step for determining a position error of each of the detected objects based on the determined positions and calculating a first probability as a probability that the detected objects are identical with respect to the position from the determined position error based on a normal distribution concerning the position error when the plurality of sensors detect the identical object; a third step for determining a speed error of each of the detected objects based on the determined speed and calculating a second probability as a probability that the detected objects are identical with respect to the speed from the determined speed error based on a normal distribution concerning the speed error when the plurality of sensors detect the identical object; a fourth step for calculating a third probability as a probability that the detected objects are identical based on the calculated first probability and the calculated second probability; and a fifth step for determining that the detected objects are identical if the third probability exceeds a first determination value.
