IMAGE MATCHING APPARATUS, CONTROL METHOD, AND NON-TRANSITORY COMPUTER-READABLE STORAGE MEDIUM

The image matching apparatus ( 2000 ) comprises a ground-view feature extractor ( 2020 ), an aerial-view feature extractor ( 2040 ), and a determination unit ( 2060 ). The ground-view feature extractor ( 2020 ) extracts features from the ground-view image ( 20 ) to generate feature maps without attention mechanism and feature maps with attention mechanism. The aerial-view feature extractor ( 2040 ) extracts features from the aerial-view image ( 30 ) to generate feature maps without attention mechanism and feature maps with attention mechanism. The determination unit ( 2060 ) computes a similarity score, which indicates a degree of similarity between the ground-view image ( 20 ) and the aerial-view image ( 30 ), based on the generated feature maps. Then, the determination unit ( 2060 ) determines whether the ground-view image ( 20 ) matches the aerial-view image ( 30 ) based on the similarity score.
