1. A method for setting frame rates of a camera, wherein the camera comprises a plurality of image sensors arranged to capture images to be stitched into a panorama image of a scene, and wherein a plurality of panorama images are combinable into video segments and each of the plurality of image sensors has a respective optical axis, the method being performed by a controller, the method comprising:
obtaining information of a respective angle (αk;k=1 . . . K) between the optical axis of each of the plurality of image sensors and a direction along which a straight path structure, to be monitored by the camera, extends through the scene;
dividing the plurality of image sensors into at least two groups as a function of the angles (αk;k=1 . . . K), wherein all the angles (αk;k=1 . . . K) of the image sensors within each of the at least two groups are part of its own continuous angle interval; and
setting one frame rate per each of the at least two groups, wherein the frame rate decreases from the group with highest continuous angle interval towards the group with lowest continuous angle interval.
