Different methods of human posture risk assessment.

CategoryDeviceApproachContributionReferences

Contact sensor methodMoCapCollect joint coordinatesAn inertial sensor approach was developed to evaluate the working posture of workers on an automotive assembly line[13]
IMU sensorCollect joint coordinatesA real-time motion alert personal protective equipment (PPE) based on a wearable inertial measurement unit (Wimu) was developed to enable workers to self-awareness and self-management of ergonomic hazardous operating modes to prevent WMSDs[14]

Noncontact vision methodKinect v2Human key point recognitionProposing a semiautomatic RULA evaluation software based on Microsoft Kinect v2 depth camera[15]
Kinect v2Depth image acquisition and segmentationA skeleton less holistic pose analysis system is proposed to accurately predict operational pose limb angles from a single depth image[16]
RGB-D camera2D pose estimation based on CEPARAA PAS-oriented holistic pose acquisition and ergonomic risk analysis model is proposed for developing a smartphone-based and workplace-based WMSDs risk assessment system[17]
RGB-D camera2D pose estimationA proposed vision-based real-time RULA method for scoring RULA levels of individual images captured by ordinary RGB cameras[18]
RGB-D camera3D pose estimation based on 3DMPPEThe body angle reliability decision making (BARD) method is proposed to calculate the most reliable body bending angle[2]
