Position detecting apparatus and computer-readable recording medium

A position detecting apparatus comprising:

• an image storage portion that stores image data obtained by imaging an object when a feature portion is positioned at a plurality of respective target positions by a moving mechanism configured to change a position of the object in which the feature portion for positioning is provided;
• an image processing portion that detects positions of the feature portion that is included in the image data from the image data through image processing;
• a position storage portion that stores the detected positions detected by the image processing portion in association with the target positions from the image data of the object positioned at the respective target positions;
• a cause storage portion that stores a plurality of predefined cause data items that have evaluation content that represents evaluation of positional differences from the target positions in a coordinate system and an estimated cause estimated for the positional differences in linkage with the evaluation content;
• an evaluation portion that evaluates detection differences that are differences between the target positions and the associated detected positions in the coordinate system in the position storage portion on the basis of a predefined reference;
• and
• a display data generation portion that generates data for displaying information related to the evaluation on a display unit,
• wherein the display data generation portion generates data for displaying the estimated cause in the cause storage portion, which corresponds to the evaluation content that represents evaluation by the evaluation portion.

A non-transitory computer-readable recording medium comprising a program for causing a computer to execute a position detecting method, the position detecting method comprising the steps of:

• detecting a position of a feature portion that is included in image data from the image data acquired by imaging an object through image processing when the feature portion is positioned at a plurality of respective target positions by a moving mechanism configured to change a position of the object in which the feature portion for positioning is provided;
• storing the detected positions detected through the image processing in association with the target positions from the image data of the object positioned at the respective target positions;
• and
• generating data for displaying information related to the detected positions on a display unit,
• wherein the generating of the data for displaying the information includes generating data for displaying the respective target positions and the respective detected positions stored in association with the target positions in the same coordinate space.
