Claim 5:
6. The method according to claim 4, wherein the preset rule for judging missed detection comprises:
in a case that no adjacent ultrasonic radars of the to-be-judged ultrasonic radar returns obstacle coordinates, it is judged there is no missed detection in the to-be-judged ultrasonic radar;
in a case that one adjacent ultrasonic radar of the to-be-judged ultrasonic radar returns obstacle coordinates, if the coverage ranges of the to-be-judged ultrasonic radar and the adjacent ultrasonic radar returning obstacle coordinates have an overlapped coverage range of two ultrasonic radars, it is judged there is missed detection; if the coverage ranges of the to-be-judged ultrasonic radar and the adjacent ultrasonic radar returning the obstacle coordinates only have an overlapped coverage range of three ultrasonic radars, it is judged there is no missed detection;
in a case that two adjacent ultrasonic radars of the to-be-judged ultrasonic radar return obstacle coordinates, if the coverage ranges of the to-be-judged ultrasonic radar and the adjacent ultrasonic radars returning the obstacle coordinates have an overlapped coverage range of three ultrasonic radars, it is judged there is missed detection; if the coverage ranges of the to-be-judged ultrasonic radar and the adjacent ultrasonic radars returning obstacle coordinates do not have an overlapped coverage range of three ultrasonic radars, it is judged there is no missed detection;
in a case that three or more adjacent ultrasonic radars of the to-be-judged ultrasonic radar return obstacle coordinates, it is judged there is missed detection.
