In various industries, the accurate recognition and analysis of movement patterns in three-dimensional space is becoming increasingly crucial. 3D Motion Recognition, also known as 3D Movement Recognition, offers a transformative solution to address a wide range of challenges in both human-centric and industrial applications. In this article, we will explore the power of 3D Motion Recognition and its ability to revolutionize various domains.

Improving Human-centric Functions and Movements

Healthcare and Rehabilitation 

In healthcare, 3D Motion Recognition (Movement Recognition) plays a vital role in enhancing patient care and safety. By accurately estimating human pose through key points, healthcare professionals can monitor patient movements, detect dangerous situations such as falls, and analyze illness-related motions. This technology offers valuable insights for clinical activities, enabling healthcare providers to optimize workflows and improve treatment outcomes.

Fitness and Sport 

3D Motion Recognition is also beneficial in fitness applications. It enables the recognition and analysis of physical exercises and movements, allowing individuals to receive personalized insights and guidance. By measuring more features using 3D data, this solution provides a more comprehensive assessment than traditional methods, ensuring correct posture and minimizing the risk of injuries.

Virtual Reality and Gaming 

The integration of 3D Motion Recognition with virtual reality (VR) and gaming opens up exciting possibilities. By utilizing Microsoft Azure Kinect 3D cameras, markerless motion capture can be achieved. Real-world objects can be analyzed, and their movements can be replicated in the form of 3D models, enriching the immersive experience in the metaverse, gaming, and VR scenarios.

Industrial Applications

Human-Machine Collaboration 

In industrial settings where humans and machines work together, 3D Motion Recognition proves invaluable. By precisely detecting and tracking the movements of people, potential risks can be identified, workflows can be optimized, and accidents and errors can be prevented. This technology ensures a safer and more efficient collaboration between human workers and machines.

Workflow Optimization 

By leveraging the technology, businesses can gain insights into the movements of employees within different environments. Analyzing these movements enables organizations to identify bottlenecks, streamline processes, and enhance overall productivity. The data collected through this technology can be used to optimize workflows, reduce operational costs, and improve the overall efficiency of industrial operations.

As industries strive for greater efficiency, safety, and productivity, the adoption of 3D Movement Recognition solutions is on the rise. By accurately recognizing and analyzing movements in three-dimensional space, businesses can unlock valuable insights, optimize processes, and improve outcomes in both human-centric and industrial domains. Whether in healthcare, fitness, virtual reality, or industrial settings, the transformative power of 3D Movement Recognition is paving the way for a future of enhanced performance and safety.

How Does 3D Movement Recognition Work?

3D movement recognition is an advanced technology that allows for precise tracking and analysis of human motion. It works on the principles of human motion tracking, using advanced 3D pose estimation software and motion-type classification algorithms to capture and analyze movements in three dimensions. 

The basis of this technology is the accurate estimation of the position of human key points (knees, elbows, shoulders, etc.) in 3D. There are several different techniques for estimating human pose, depending on the type and number of cameras used in the solution. 

A minimalist approach in terms of the number of devices is to use one camera that has the ability to record depth images. Thanks to this, information about the distance from the camera of the recorded objects is obtained, and dedicated artificial intelligence models return information about the location of key points in three dimensions. However, this solution is burdened with a certain error due to the fact that the model is not able to estimate the location of body parts not visible in the camera view. 

This issue does not occur when the approach is based on multiple camera views. By registering the image from different sides, the problem of occlusions is eliminated. This solution requires calibration of all devices to be able to identify the same points visible from different cameras, and thus create a 3D scene. An additional advantage of this approach is that there is no need to use depth-recording cameras because the entire solution is based on color images. Pose estimation in this case can be performed using the triangulation method. This means that the 2D pose estimation is performed on each view separately, and then, thanks to the calibration data, a 3D pose is generated combining information from all 2D poses. Another possibility is the use of special neural networks that, based on calibration data and views from several cameras, return the human pose directly in 3D. 

After obtaining information about the location of key points in time, algorithms are used to analyze this data. These can be simple mathematical algorithms interpreting the position of key points in relation to each other and on this basis classifying a given movement or recognizing errors. Another approach is to use neural networks, that learn during the training which features are crucial to correctly identify movement.
