Position detection device of this kind and position determination methods are based and management device and a management method

摘要

A moving object position recognizing device for judging an area where a moving object is located, the device comprising a moved distance judging unit for judging whether or not a moving object has moved a predetermined distance corresponding to an detection error for a moving object position, and an area judging unit for judging an area where the moving object is located when it is judged that the moving object has moved a predetermined distance. Accordingly, when the position of a moving object cannot be detected accurately, an area where the moving object exists is not judged . Therefore, an accuracy with which to judge an area where the moving object is present is improved, and there is no need of setting a buffer area, which would be used as a criteria for judging area where the moving object is present and in which an area where a moving object is present is not judged when the moving object is located in the vicinity of this position . Accordingly, the amounts of data and computation can be reduced as much as a buffer area not provided to thereby restrain an increase in production costs of a position recognizing device.
