Target Overview

MetriCal relies on targets to provide metric information that is otherwise difficult to obtain from an unstructured data collection, enabling accurate estimation of both intrinsic and extrinsic parameters.

MetriCal can support an arbitrary number of targets in a single calibration procedure without any special configuration. This means you can mix and match different target types to suit your specific calibration needs.

Object Space Configuration Files

In MetriCal, targets refer to the physical objects used during calibration. The software then converts that to features or patterns that it can detect in the collected data. These features are represented in MetriCal as object spaces.

MetriCal requires an object space file in order to understand the geometry and layout of the targets being used. You'll find pre-defined object space templates for each target type within the target guides.

Build Or Buy?

You'll find common calibration target combinations in our target construction guide. We recommend starting here if you just want to jump into MetriCal, since these configurations are similar to what is used in our calibration guides. We also outline how to print and build your own targets via services like UPrinting. However, if you're strapped for time, you can also purchase calibration targets directly from our online store.
