Distortion correcting sensors for diagonal collection of oblique imagery

A method comprising:

• operating a vehicle in a nominal heading;
• capturing oblique imagery of a surface via one or more respective camera-groups;
• wherein at least one of the respective camera-groups is oriented at a particular plan angle with respect to the nominal heading and includes a plurality of distortion correcting electronic image sensors;
• wherein the particular plan angle is an oblique angle with respect to the nominal heading;
• and
• wherein a camera of the at least one of the respective camera-groups has an associated Petzval surface, and each of the distortion correcting electronic image sensors is rotated at a respective angle based at least in part on a respective position of the respective distortion correcting electronic image sensor in the Petzval surface.

An apparatus comprising:

• one or more respective camera-groups each enabled to capture oblique imagery of a surface, the respective camera-groups are enabled to operate in a vehicle in accordance with a nominal heading;
• at least one distortion correcting electronic image sensor included in at least one of the respective camera-groups, the at least one of the respective camera-groups are oriented at a particular plan angle with respect to the nominal heading;
• wherein the particular plan angle is an oblique angle with respect to the nominal heading;
• wherein the at least one distortion correcting electronic image sensor comprises one or more one-dimensional collections of a plurality of pixel elements;
• and
• wherein the at least one distortion correcting electronic image sensor is configured such that the one-dimensional collections, when projected onto the surface, are aligned to the nominal heading.
