Linear Accuracy Testing: 3D Scanning a 24″ Ball Bar with Artec Space Spider

Published on October 13, 2020.

Our team underwent two separate accuracy tests to see how the Artec Space Spider will fare when 3D scanning tricky parts. In this second test, we’ve conducting a linear accuracy test with the system. A ball bar is a telescoping bar with precision balls at each end. It is often used in testing the accuracy of a measurement device (in this case, the Artec Space Spider) because it has a known distance. For this test, the true value of the distance between the center points of the two balls is 24.0195”.
