Markerless motion capture is a novel technique. It segments and analyzes the captured images and USES several constraint algorithms to reconstruct.

无标记点的运动捕捉是新兴的技术，它将捕获的图像进行分割并分析，然后用多种约束算法进行三维重建。

Therefore, recognition off a barcode, marker or markerless image makes up a vital portion of AR, so it is less about the differences between the two and more about their working relationship.
