[Solution] An information processing device comprising: a determination unit that determines that a first object was detected, using a detection model, from a first image included in an image group which is a chronological series, said first object having not been detected from at least one second image which is included in the image group and is chronologically before the first image; a tracking unit that extracts, from the at least one second image, the first object which has been occluded by a second object according to a prescribed condition; a labeling unit that labels the first object which was extracted from the at least one second image; a training unit that performs training with the at least one second image which includes the labeled first object; an update unit that updates the detection model on the basis of the training result from the training unit; and a detection unit that implements the updated detection model and thereby detects, from a third image, a third object which has been occluded according to the prescribed condition.
