BODY ORIENTATION ESTIMATING PROGRAM, BODY ORIENTATION ESTIMATING DEVICE, AND BODY ORIENTATION ESTIMATING METHOD

摘要

To accurately estimate an orientation of a human body captured in an image.SOLUTION: An area extracting section 22 extracts a person area which shows an area of a person, from an image captured at a first time point and an image captured at a second time point later than the first time point, respectively. Then, a specifying section 24 specifies a left side site showing a specific site on a left side in the person area, and a right side site showing a specific site on a right side in the person area, of the first time point and the second time point respectively. Further, a calculating section 25 calculates a left side moving amount expressing a moving amount between the left side site at the first time point and the left side site at the second time point, and a right side moving amount expressing a moving amount between the right side site at the first time point and the right side site at the second time point. Furthermore, an estimating section 28 estimates an orientation of a human body captured in the person area at the second time point, on the basis of a difference between the left side moving amount and the right side moving amount, and a relationship between the difference and a change amount of an orientation of the human body shown in the person area.SELECTED DRAWING: Figure 1
