Station placement assistance method, station placement assistance apparatus and station placement assistance program

A station placement assistance apparatus comprising:

• a processor;
• and
• a storage medium having computer program instructions stored thereon, when executed by the processor, perform to:
• generate base station positional relationship specification data indicating a positional relationship between travel trajectory and a base station candidate position, and terminal station positional relationship specification data indicating a positional relationship between the travel trajectory and a terminal station candidate position, based on travel trajectory data indicating the travel trajectory of a moving body for measuring an object present in a three-dimensional space within a measurable distance predetermined and acquiring point cloud data indicating a position of the object measured in the three-dimensional space, the measurable distance, base station candidate position data indicating a candidate position for installing a base station apparatus, and terminal station candidate position data indicating a candidate position for installing a terminal station apparatus;
• and
• specify a reliability coefficient indicating a degree of reliability of a processing result of a prescribed evaluation processing performed based on the point cloud data, based on the base station positional relationship specification data and the terminal station positional relationship specification data;
• wherein specify the reliability coefficient includes calculating a first reliability index value for the base station candidate position by applying a first function indicating a higher reliability index value as the distance from the travel trajectory is shorter to the base station positional relationship specification data, calculating a second reliability index value for the terminal station candidate position by applying a second function indicating a higher reliability index value as the distance from the travel trajectory is shorter to the terminal station positional relationship specification data, and specifying the reliability coefficient based on the first reliability index value and the second reliability index value calculated.

A non-transitory computer-readable medium having computer-executable instructions that, upon execution of the instructions by a processor of a computer, cause the computer:

• specifying a positional relationship including generating base station positional relationship specification data indicating a positional relationship between travel trajectory and a base station candidate position, and terminal station positional relationship specification data indicating a positional relationship between the travel trajectory and a terminal station candidate position, based on travel trajectory data indicating the travel trajectory of a moving body for measuring an object present in a three-dimensional space within a measurable distance predetermined and acquiring point cloud data indicating a position of the object measured in the three-dimensional space, the measurable distance, base station candidate position data indicating a candidate position for installing a base station apparatus, and terminal station candidate position data indicating a candidate position for installing a terminal station apparatus;
• and
• specifying a reliability coefficient indicating a degree of reliability of a processing result of a prescribed evaluation processing performed based on the point cloud data, based on the base station positional relationship specification data and the terminal station positional relationship specification data;
• wherein specifying the reliability coefficient includes calculating a first reliability index value for the base station candidate position by applying a first function indicating a higher reliability index value as the distance from the travel trajectory is shorter to the base station positional relationship specification data, calculating a second reliability index value for the terminal station candidate position by applying a second function indicating a higher reliability index value as the distance from the travel trajectory is shorter to the terminal station positional relationship specification data, and specifying the reliability coefficient based on the first reliability index value and the second reliability index value calculated.
