Abstract
A posture estimation apparatus includes: a position calculation unit that calculates, for each joint of each of persons detected from image data, a provisional reference position of the person, based on a position of the joint and a displacement from the joint to a site serving as a reference for the person; and a posture estimation unit that determines a person to which the joint belongs based on the provisional reference position calculated for each joint detected.
Claims15
A posture estimation apparatus comprising:
- at least one memory storing instructions;
- and
- at least one processor configured to execute the instructions to:
- calculate, for each joint of each of persons detected from image data, a provisional reference position of the person, based on a position of the joint and a displacement from the joint to a site serving as a reference for the person;
- determine a person to which the joint belongs based on the provisional reference position calculated for each joint detected;
- and
- in a case where the site serving as a reference for each of the persons is detected from the image data, obtain, for each joint detected, a distance matrix between the provisional reference positions and a position of the site serving as a reference which has been detected, and determine a person to which the joint belongs using the distance matrix obtained.
A posture estimation method comprising:
- calculating, for each joint of each of persons detected from image data, a provisional reference position of the person, based on a position of the joint and a displacement from the joint to a site serving as a reference for the person;
- determining a person to which the joint belongs based on the provisional reference position calculated for each joint detected;
- and
- in a case where the site serving as a reference for each of the persons is detected from the image data, in the determining of the person, for each joint detected, a distance matrix between the provisional reference positions and a position of the site serving as a reference which has been detected is obtained, and a person to which the joint belongs is determined using the distance matrix obtained.
A non-transitory computer-readable recording medium that includes a program recorded thereon, the program including instructions that cause a computer to:
- calculate, for each joint of each of persons detected from image data, a provisional reference position of the person, based on a position of the joint and a displacement from the joint to a site serving as a reference for the person;
- determine a person to which the joint belongs based on the provisional reference position calculated for each joint detected;
- and
- in a case where the site serving as a reference for each of the persons is detected from the image data, in the determining of the person, for each joint detected, a distance matrix between the provisional reference positions and a position of the site serving as a reference which has been detected is obtained, and a person to which the joint belongs is determined using the distance matrix obtained.
