Detailed Description

Non-linear factor for 2D projection measurement obtained using a rolling shutter camera. The calibration is known here. This version takes rolling shutter information into account as follows: consider two consecutive poses A and B, and a Point2 measurement taken starting at time A using a rolling shutter camera. Pose A has timestamp t_A, and Pose B has timestamp t_B. The Point2 measurement has timestamp t_p (with t_A <= t_p <= t_B) corresponding to the time of exposure of the row of the image the pixel belongs to. Let us define the alpha = (t_p - t_A) / (t_B - t_A), we will use the pose interpolated between A and B by the alpha to project the corresponding landmark to Point2.
