An optical axis of the imaging system is at a first angle with respect to the planar surface of the target pattern plane when the calibration target is being used to calibrate the imaging system. The plurality of markers is pre-warped in size and aspect ratio using a set of trigonometric functions that use the first angle and a distance from the imaging system to the marker, so that each of the plurality of markers appears a substantially same size as all others of the plurality of markers when viewed by the imaging system at the first angle. The plurality of markers includes a plurality of localizer features that have known relative positions on the target pattern plane and are used to determine an orientation for each marker."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Targets, fixtures, and workflows for calibrating an endoscopic camera","description":"A calibration target comprises a target pattern plane having a planar surface and a plurality of markers disposed on the planar surface.
