Evaluation apparatus, evaluation method, and non-transitory storage medium

An evaluation method of evaluating an arrangement of one or more image capturing apparatuses that surveil a target region, the method comprising:

• acquiring arrangement information and environmental information, the arrangement information indicating at least any of a position of the image capturing apparatus, an orientation of the image capturing apparatus, and a field angle of the image capturing apparatus, and the environmental information indicating an environment of the target region;
• computing, for each of a plurality of positions in the target region, a surveillance index by using the arrangement information and the environmental information, the surveillance index indicating difficulty or easiness of surveilling a target object in a case where the target object is located at the position;
• and
• computing suitability of the arrangement of the image capturing apparatus, which is indicated by the arrangement information, based on distribution of the surveillance index in the target region.

A non-transitory storage medium storing a computer program for realizing an evaluation apparatus that evaluates an arrangement of one or more image capturing apparatuses that surveil a target region, the program causing a computer to:

• acquire arrangement information and environmental information, the arrangement information indicating at least any of a position of the image capturing apparatus, an orientation of the image capturing apparatus, and a field angle of the image capturing apparatus, and the environmental information indicating an environment of the target region;
• compute, for each of a plurality of positions in the target region, a surveillance index by using the arrangement information and the environmental information, the surveillance index indicating difficulty or easiness of surveilling a target object in a case where the target object is located at the position;
• and
• compute suitability of the arrangement of the image capturing apparatus, which is indicated by the arrangement information, based on distribution of the surveillance index in the target region.
