When I learned that the strategy for collecting and returning samples included a rover that was going to cache samples on the surface for another rover to find, the geocacher in me was stirred with childlike glee that the rovers would be doing something that resembles geocaching on Mars. The primary target is the golden structure with the bulls-eye pattern bottom right. Image credit: NASA/JPL-Caltech/Tanya Harrison. Secondary Target. If you look through the raw images on NASA’s website and filter by SHERLOC and WATSON, you can find a picture of the calibration target and then “virtually” log the tracking code on the geocaching website. BoofCV provides an application for generating your own custom calibration target. If the aim of a camera calibration is to reuse the calibration in high accuracy applications, then the calibration must not be specific to a particular camera network. A typical image of a metrology target is shown in Fig. so that the slave has an overview of the region in which it will be used to track objects.
