<p>PROBLEM TO BE SOLVED: To provide a technique capable of reducing the processing load to object detection using a distorted image while improving detection accuracy.SOLUTION: Target model storage means (20) stores a target model prepared for each detection target object. Image acquisition means (S110) acquires an image having a distortion. Feature extraction means (S120 to S130) extracts an image feature amount that is a feature amount of each unit region clipped from the image on the basis of the image acquired by the image acquisition means. Model adjustment means (S160) defines search points set in a three-dimensional space that is an imaging target space for the image as projected search points, and adjusts the target model in response to a degree of the image distortion determined for each projected search point. Object detection means (S170) detects an object corresponding to the target model by evaluating the similarity between the image feature amount extracted by the feature extraction means and an adjustment model that is the target model adjusted by the model adjustment means.</p> |
