Problems solved by technology

For example, the current scoring method in gymnastics competitions is performed by the eyes of multiple referees. However, due to the evolution of equipment, the improvement of training methods, and the sophistication of behaviors accompanied by the complexity of sports, the recognition of behaviors by referees appears. Situations that become difficult
As a result, there are concerns about the maintenance of the fairness and accuracy of the scoring results of the players, which vary from judge to judge

Embodiment 1

[0042] [the whole frame]

[0043] figure 1 It is a figure which shows the whole structure example of the system of Example 1. Such as figure 1 As shown, the system has a 3D (Three-Dimensional: three-dimensional) laser sensor 5, a learning device 10, a recognition device 50, and a scoring device 90. A scoring system for behaviors. In addition, in this embodiment, as an example, an example of identifying skeleton information of a performer in a gymnastics competition will be described.

[0044] In general, the current scoring method in gymnastics competitions is performed by the eyes of a plurality of scorers, but with the sophistication of activities, it becomes more and more difficult to score with the eyes of the scorers. In recent years, automatic scoring systems and scoring support systems for scoring games using 3D laser sensors have been known. For example, in these systems, a distance image that is three-dimensional data of a player is acquired by a 3D laser sensor,...

Abstract

The recognition device acquires, in time series, skeleton information based on position information of each of a plurality of joints including a specific joint of a moving subject. Then, the recognition device estimates a region in which a specific joint is located, from among a plurality of regions obtained by dividing a region of an object used in motion, using position information of a plurality of joints included in each of the time-series skeleton information. Then, the recognition device recognizes the motion of the subject using the time-series bone information and the estimated position of the specific joint, and outputs a recognition result.

Description

technical field [0001] The invention relates to a motion recognition method, a motion recognition program and an information processing device. Background technique [0002] In a wide range of fields such as gymnastics and medical care, the movement of a person is automatically recognized using the skeleton information of a person such as a player or a patient. For example, the current scoring method in gymnastics competitions is performed by the eyes of multiple referees. However, due to the evolution of equipment, the improvement of training methods, and the sophistication of behaviors accompanied by the complexity of sports, the recognition of behaviors by referees appears. Situations that become difficult. As a result, there has been concern about maintaining the fairness and accuracy of the scoring results of the players, which vary from judge to judge. [0003] Therefore, in recent years, an automatic scoring technique using a player's three-dimensional skeleton coor...
