Device and method for relative positioning of multi-aperture optics comprising several optical channels in relation to an image sensor

Device for relative positioning of multi-aperture optics comprising several optical channels in relation to an image sensor, comprising:

• a reference object arranged such that the reference object is imaged to an image region per channel by the multi-aperture optics in the optical channels;
• a positioning device controllable to change a relative location between the multi-aperture optics and the image sensor;
• a calculating device configured to determine actual positions of the reference object in at least three image regions in images of the reference object and to control the positioning device on the basis of a comparison of the actual positions with positions,
• wherein at least four outer image regions and one inner image region are arranged along a roll axis and a pitch axis, the outer image regions being arranged in two opposing pairs in parallel with the roll axis and in two opposing pairs in parallel with the pitch axis, the roll axis and the pitch axis being arranged to be perpendicular to each other and to be perpendicular to a yaw axis arranged in parallel with a surface normal of the image sensor, and the inner image region comprising an intersection point of the roll axis, the pitch axis, and the yaw axis, and wherein the calculating device is configured to determine, on the basis of the comparison of the actual positions with the position, a pattern deviation of a pattern in the inner image region and in the at least four outer image regions.
