Markerlessjärjestelmät

Markerless motion capture systems are a type of technology used to track the movement of objects or individuals without the need for special markers attached to them. Unlike traditional marker-based systems that rely on reflective markers or active LEDs placed on the body or object, markerless systems use computer vision and algorithms to detect and follow features in the environment or the subject's natural appearance. These systems typically employ one or more cameras to capture video data. Sophisticated algorithms then analyze this data to identify key points, such as joints, limbs, or distinct shapes, and infer their movement over time. Markerless systems can be broadly categorized into those that track human motion and those that track general object motion. Human motion capture often involves analyzing skeletal structure and pose estimation, while object tracking might focus on identifying and following unique textures or contours. The advantages of markerless systems include a simpler setup process, greater freedom of movement for the subject, and the ability to capture motion in real-world environments without intrusive equipment. However, they can sometimes be more susceptible to occlusions, variations in lighting, and complex backgrounds, potentially leading to less precise tracking compared to marker-based methods in certain scenarios.
