Posture estimation for ergonomic analysis : Feasibility assessment using a virtual mannequin

The use of Kinect for measuring operators’ postures for ergonomic analysis is very promising. In the following article, we aimed to ensure the robustness of Kinect in conducting reliable ergonomic evaluations.

Our research has shown that using Kinect in suboptimal capture conditions frequently results in erroneous kinematic data. To conduct this experiment, we developed an evaluation method based on a virtual mannequin.

This evaluation method allowed us to test over 500,000 different postures ! Such an extensive evaluation would have been impossible with traditional protocols. The results obtained with the virtual mannequin corresponded to those obtained from measurements on a real individual.

The proposed evaluation method, described in this article, enabled us to identify postural configurations with estimation errors and simultaneously develop a measurement tool to evaluate them with high precision.

Validation of the ergonomic analysis method using kinect in real work situations

In this article, we present the analysis of a RULA ergonomic evaluation in real work conditions, building on previously published work on the validation of Kinect in a laboratory setting.

The results are promising: they show that the method is valid for ergonomic evaluation on a production line, reinforcing the findings of laboratory research.

Furthermore, the speed of obtaining results allows for real-time visual feedback and interactions with the operator filmed by Kinect.

This research opens the perspective for a new, more effective ergonomic analysis method in detecting musculoskeletal disorders.

The use of corrected Kinect measurements for ergonomic analysis in constrained environments

In this article, we evaluate the validity of using Kinect measurements corrected by our algorithms for ergonomic assessment.

Assessing the potential risks of musculoskeletal disorders in real workstations is a significant challenge, as the environment is often cluttered, making it difficult to evaluate the operator’s postures.

The Kinect is a promising tool for posture evaluation… However, it can sometimes provide inaccurate results, especially when there is occlusion or improper camera placement relative to the operator.

To address this issue, we proposed a solution to detect and correct inaccurate estimations of certain parts of the operator’s body using a method that employs a learning database representing a set of example postures.

Our results showed that when there is occlusion, the raw Kinect data can be significantly improved using our correction method, resulting in reliable and valid joint angles and RULA ergonomic scores.

Our study thus opens up new perspectives for establishing new fatigue and strain indexes based on continuous measurement… Unlike traditional ergonomic methods that rely on static images.

Are joint angles estimated from corrected Kinect data reliable for ergonomic assessments ?

Discover our study demonstrating the feasibility of using corrected Kinect data – to feed an inverse dynamics method – for estimating joint torques in the context of an ergonomic assessment.

Indeed, forces and joint torques are particularly relevant indicators in the biomechanical analysis of occupational risks at workstations.

Our article explores the use of corrected Kinect data and inverse dynamics to reliably estimate joint torques, even in cases of occlusion or suboptimal sensor placement.

Research shows that using depth cameras, like the Microsoft Kinect, offers promising results for real-time 3D posture measurement. The use of depth cameras is also less intrusive for operators.

Our article also demonstrates that this method could be used on-site in real conditions to assist ergonomists in their ergonomic analysis.
