Problems solved by technology

If the number of locations to be displayed or the time to be displayed is too much, the contents of the notification will become complicated, and it will take time and effort to confirm.
On the other hand, when the number of positions to be presented or the time to be presented is too small, the necessary analysis results cannot be obtained sufficiently.

Embodiment approach 1

[0075] figure 1 It is a system configuration diagram showing an example of the configuration of the motion analysis system according to Embodiment 1 of the present invention.

[0076] In this embodiment, the present invention will be described as an example of a motion analysis system applied to a factory where skilled workers and general workers work for analyzing the motion of each general worker. The operator's actions are a series of actions consisting of a plurality of unit actions such as taking parts into the hand, placing them on the product body, screwing and fixing them, and attaching seals. More specifically, the motion analysis system of this embodiment photographs the posture of a skilled worker engaged in a certain operation process, and photographs the postures of each general worker engaged in the same operation process at the same imaging angle, and The movement of each general worker is analyzed. Hereinafter, the general unit action described above and the ...

Embodiment approach 2

[0192] Embodiment 2 of the present invention is a motion analysis device capable of switching the type of motion to be presented.

[0193] Figure 8 It is a block diagram showing an example of the structure of the motion analysis device of this embodiment, and is the same as that of Embodiment 1. figure 2 corresponding figure. right with figure 2 The same reference numerals are attached to the same parts, and related explanations are omitted.

[0194] exist Figure 8 Among them, the action analysis device 300b has an action extraction unit 322b and an action extraction degree adjustment unit 324b for performing different actions, instead of the action extraction unit and the action extraction degree adjustment unit in Embodiment 1, and an extraction category input unit 326b is newly added.

[0195] Extracted category input section 326b accepts specification of an action category to be presented to the user via input device 500, and outputs the specified category (hereina...

Embodiment approach 3

[0218] Embodiment 3 of the present invention is a motion analysis device in which the feature quantity representing the motion feature is the time weight in the CHLAC feature, and the time weight is used for motion extraction.

[0219] Figure 12 It is a block diagram showing an example of the structure of the motion analysis device of this embodiment, and is the same as that of Embodiment 1. figure 2 corresponding figure. right with figure 2 The same reference numerals are attached to the same parts, and related explanations are omitted.

[0220] exist Figure 12 In this case, the motion analysis device 300c includes a motion feature extraction unit 321c and a motion extraction unit 322c that perform different motions, instead of the motion feature extraction unit and the motion extraction unit in the first embodiment.

[0221] Motion feature extraction section 321c learns a weight map that defines weights for each frame (see Non-Patent Document 2). Then, the action f...

Abstract

A motion analysis apparatus is provided that enables an analysis result presentation quantity to be easily adjusted. A motion analysis apparatus (300) is an apparatus that performs analysis of motion subject to comparison (compared motion) by means of comparison with standard motion, and has a motion feature extraction section (321) and motion extraction section (322) that determine a location where a degree of difference between a motion subject to comparison and a standard motion satisfies a predetermined condition, a presentation quantity input section (323) that receives a specification of a presentation quantity of locations that satisfy the predetermined condition, and a motion extraction degree adjustment section (324) that adjusts the predetermined condition so that a quantity of locations satisfying the predetermined condition becomes the specified presentation quantity.

Description

[0001] This application is a divisional application of an invention patent application with a filing date of December 20, 2010, an application number of 201080008083.9, and an invention title of "motion analysis device and motion analysis method". technical field [0002] The present invention relates to a motion analysis device and a motion analysis method for analyzing a comparison target motion by comparing with a standard motion. Background technique [0003] Conventionally, devices and methods for analyzing a comparison target motion by comparing with a standard motion have been proposed (see, for example, Non-Patent Document 1 and Non-Patent Document 2). [0004] The device described in Non-Patent Document 1 performs behavior measurement using acceleration sensors attached to various parts of the driver's body, and performs behavior analysis using independent component analysis and a type of SVM (Support Vector Machine). More specifically, the device described in Non-P...
