I&#x27;m curious if the asymmetry has anything to do with the &quot;computational&quot; component, e.g. in solving a system of equations (like estimating distance across multiple sensors), it&#x27;s best to have an independent basis. If the sensors were arranged in a perfect grid pattern, then comparing some sets of sensors (i.e. colinear ones) wouldn&#x27;t give you as much data as others?<p>...or perhaps I&#x27;m letting my understanding of computer vision&#x2F;geometry&#x2F;linear algebra run away from me...
