<p>PURPOSE:To prevent double counting and counting omission by detecting human bodies by different detection references, deciding the coincidence of a bearing in which the human body is detected in a short distance side visual field with a bearing in which the human body is detected in a long distance visual field and deciding the number of persons based on the detection result and the decision result of a bearing coincidence deciding part. CONSTITUTION:A judging part 5 contains a human body detecting part 51 able to detect the human bodies by different detection references L1 and L2, a bearing coincidence deciding part 52 to decide the coincidence of the bearing in which the human body is detected in a short distance side visual field Fa with the bearing in which the human body is detected in a long distance side visual field Fb, and a number-of-persons deciding part 53 to decide the number of persons based on the detection result of the human body detecting part 51 and the decision result of the bearing coincidence deciding part 52. When a certain detection reference L2 is used, by detecting the human body by the different detection reference L1(>L2) even when the human body in the same bearing in the short distance side visual field Fa and the long distance side visual field Fb is detected, the state in which the human bodies exist respectively in the respective visual fields Fa and Fb can be distinguished from the state in which one human body exist in both the visual fields Fa and Fb and the repeated counting and counting omission of the human bodies can be prevented.</p> |
