Abstract
Motion capture and motion analysis are employed in animation development and modeling of body movements in various fields. A typical motion capture system requires markers to identify the movement performed by objects in motion that is being tracked. A passive marker is built from light-reflecting materials, and the motion capture systems require lighting during the motion capture. The purpose of this study is to examine the influence of colors and sizes of markers on its reflection rate index (RRI). This study involved the RRI of 12 different markers with various sizes (10, 14, and 18 mm) and colors (blue, red, gold, and silver). Based on the RRI value, the type and level of reflection and light distribution from each marker were identified. The results reveal that silver marker has an RRI value above 1, while blue, red, and gold markers have an RRI value below 1. Based on this study, we can categorize each marker’s light reflection rate based on the calculated RRI. This is helpful to users in deciding what type of marker needs to be used in each respective area.
