被动标志点测量模块 Marker Tracking
集成的离散标志点跟踪测量功能 Intergrated Discrete Marker Tracking
VIC-3D 具备在三维空间中追踪离散标记点（圆形或领结形）的能力。与手动测量相比，该功能可大幅节省时间。此外，它还能精确测量物体向立体摄像机系统靠近或远离的运动。标记点追踪技术使得在无法进行全场散斑测量的情况下，仍可在基准点获取三维位移数据。
基于散斑图案的全场测量与离散标记点追踪可同时进行，两组数据均可在 VIC-3D 的“Iris”数据可视化工作区中进行可视化展示。
标记点还可用于将坐标系与 CAD 或有限元模型中的外部参考系进行精确对齐。请观看下方视频了解实际应用效果。
VIC-3D includes the ability to track discrete markers (circular or bow-tie format) in three dimensions. This feature provides considerable time savings compared to manual measurements. It also permits accurate measurements of movements toward or away from the stereo camera system. Marker tracking allows for 3D displacement data to be obtained at fiducial points where full-field speckling might not be possible.
Full-field measurements using a speckle pattern and discrete marker tracking may be obtained concurrently, and both data sets can be visualized in VIC-3D’s iris data visualization workspace.
Markers may also be ultilize for precise coordinate system alignment with external frames of reference in CAD or FE models. See it in action in the video to the right.
每个帧都会对标记点进行追踪 Markers are tracked for each frame | 将标记相互连接以可视化轨迹 Markers are connected together for trajectory visualization |
标记追踪功能通过所选变量的颜色表示，展示离散点处的运动情况
Marker tracing shows the movement at the discrete points with color representation of the variable chosen
