Claim 12:
13. The electronic device according to claim 11, wherein the preset rule for judging missed detection comprises:
in a case that no adjacent ultrasonic radars of the to-be-judged ultrasonic radar return 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 radar coverage ranges overlapping, 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 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.
