Blob probe box to acquire and display the many points that characterize the shape of an object.
The number of points acquired cannot be changed in the Probe Library.
The Blob probe can be used to acquire points for the measurement of regular and irregular shapes.
Select the Blob probe from the Probe menu, the live video window on-screen menu or the VED toolbar.
Move the probe, change its size or change its orientation as described earlier in this chapter.
