problem about resolution #860

Closed flyover-26 closed 2 years ago

Preliminary Checks

Proposal

I subcribe ros topic /zed2/zed_node/left_raw/image_raw_color with resolution of VGA(672372 in each side).However,I find resolution actually is 336186 which does not match with VGA.And I am not sure which Intrinsic matrix I should choose because of this problem? Looking forward to your reply!

Hi @flyover-26 please check the parameters video/img_downsample_factor for RGB and depth/depth_downsample_factor for depth. They are set to 0.5 by default to reduce the size of the published topics and reduce the required bandwidth. You can set them to 1.0 to not scale the image topics
