Communication point determination device, communication point determination method and program, and inspection system

A communication point determination device for determining a communication point including a communication position being a position of a mobile body which performs close-range wireless communication with a wireless device disposed within a target area including an obstacle which obstructs propagation of radio waves, the communication point determination device comprising:

• a first acquisition part configured to obtain a radio wave strength map indicating a distribution of a radio wave strength within the target area obtained by numerical analysis based on area shape information of the target area generated on the basis of an outer shape of the obstacle existing within the target area, installation position information of the wireless device within the target area, and radio wave information related to transmission or response of radio waves of the wireless device;
• a determination part configured to determine the communication point on the basis of the radio wave strength map;
• a second acquisition part configured to obtain a detection result of the obstacle included in at least a part of a direction of a surrounding of the communication point upon failure of the close-range wireless communication at the communication point;
• and
• a shape change determination part configured to determine, on the basis of the detection result of the obstacle, presence or absence of shape change of the detected surrounding from a shape of the surrounding indicated by the area shape information,
• wherein the determination part is configured to, if it is determined that the shape change is present, determine a new communication point instead of the communication point at which the close-range wireless communication has failed.
