Behavior recognition method, behavior recognition program and behavior recognition device

摘要

PROBLEM TO BE SOLVED: To realize updating of rules according to operation. SOLUTION: In an action recognition method, skeletal information including the positions of a plurality of joints is extracted for each frame of an image, a first motion feature amount is calculated from the skeletal information, and a second motion feature related to a higher-level action to be recognized. By plotting the first motion feature in the feature space having a plurality of mapping regions in which the range in which the quantity can be observed is mapped for each higher action, the first motion feature is plotted against the feature space. The plot position, which is the position, is calculated, and if the degree of deviation from the other distance of the minimum distance among the distances between each of the multiple mapping areas and the plot position meets a predetermined criterion, the mapping area at the minimum distance from the plot position is plotted. The computer performs the processing, performing the updates that extend based on the location. [Selection diagram] FIG. 5
