Writing camera projection matrix for HCI Dataset

[Hasan Latif]

Anyone could help me in writing camera matrix for new HCI Dataset.below parameters are given.

i could find the focal length,but there is no principal point for the camera.

image_resolution_x_px = 512

image_resolution_y_px = 512

sensor_size_mm = 35.0

fstop = 300.0

[extrinsics]

num_cams_x = 9

num_cams_y = 9

baseline_mm = 30.0

focus_distance_m = 10.0

Dear Hassan,

maybe fig 1 of our supplemental material might help: http://lightfield-analysis.net/benchmark/paper/lightfield_benchmark_accv_2016_supp.pdf

our light fields consist of 9x9 views. the coordinates of the central view are given in the extrinsics part. all other views are spaced equally on a grid of distance [baseline_mm] and shifted towards the common focus plane (see fig.1)

i hope i was able to help you!

kind regards
