MOTION CAPTURE CAMERA FULL

Some less-precise systems are growing in popularity because they are inexpensive and solve easier problems, like treadmill analysis with running. Motion capture using video is possible, but most research-grade systems prefer using infrared cameras and reflective markers. Two clear options exist with motion capture: marker or optical systems and markerless solutions.

Capturing full body motion requires a controlled environment for the system to have enough robustness to collect data properly. Some motion capture systems are designed for indoor use but have some outdoor functions that are effective and appropriate. The amount of detail and precision a user of motion capture needs determines how the data is collected, as each system has abilities and constraints with both accuracy and flexibility of the information. Motion capture is one part marking and tracking the body and one part converting that information into data that is useful for both research and applications in markets such as entertainment. Markerless cameras, such as the Microsoft Kinect device, use an infrared laser and camera together to create depth in three dimensions, but those systems have limitations in sport. IMUs used together can create motion capture data from calculations, but add another level of complexity to the challenge of measuring body motions.

Able to collect ballistic activities with high frequency of measurement.Īs you can see from this list, unless all of the requirements are met, it’s easy to confuse a single sensor recording of movement that’s raw and out of context as motion capture.

Requires a direct recording of three dimensions of data.

Provides anatomical orientation of points of reference.

Creates a complete and fully authentic acquisition of total body motion.

The criteria for true 3-D motion capture is the following: Click To TweetĪ small sensor does have the ability to collect orientation data, but unless it collects all of the body, those systems should be seen as motion sensors, and some systems do create compete renderings of movement from recordings. There is a difference between measuring motion with a few sensors and capturing a body in action. Most readers will envision reflective markings on a body to digitize an athlete in three dimensions when the term motion capture is brought up, but it’s extremely important to know what makes up a true 3-D recording. Now that IMU sensors have entered the market, an accelerometer with a gyro can seem like true motion capture, but there is a difference between measuring motion with a few sensors and capturing a body in action. However, it usually refers to a modified recording of total body motion in three dimensions.

Motion capture is a very loose term, and capturing motion can mean nearly anything now.

Motion capture is evolving and increasing in use at all levels, and sports performance professionals must stay current on the best options and best practices available. Motion capture is a very vague term, and this article articulates what exactly is true 3-D motion capture and what is not. In this guide, we look at the top options in motion capture and show the important differences in what the specific technologies can do and what they cannot. As the technology migrates from research into clinical and commercial training businesses, there are challenges in using the data to make informed choices. The use of motion capture is growing in all areas of sport and entertainment, especially at the elite level.
