Regarding obstructions, here is a photo taken along a ridge line. Dealing with obstructions to the horizonĪs almost all our photos are taken outdoors, I won’t consider photos taken indoors in these posts. It gets a bit more complicated when there are obstructions to the horizon or the photos is in an enclosed space. As it gets closer to 135 degrees, the sine wave flattens again (and is a horizontal mirror of the 45 degree wave).Īs a human, this pattern is fairly easy to spot assuming a good proportion of a horizon is visible and fairly level. As it reaches 90 degrees the curve gets closer to a square wave. You can see clear patterns as the camera rolls around the y axis.Īs the roll increases to 45 degrees the sine wave gets increasingly distorted. Reviewing the wave (with a clear horizon) You can see the timestamps I used to capture the frames in ffmpeg command įfmpeg -ss 00:00:16 -i GS010011.mp4 -frames:v 1 -q:v 40 GS018421_000016.jpg I have extracted frames at roughly (done by eye) at 0 degrees, 45 degrees, 90 degrees, 135 degrees, 180 degrees, 225 degrees, 270 degrees, and 315 degrees. Using my example roll video from a few weeks ago When you have look at enough equirectangular photos outside of a 360 viewer you begin to identify roll by eye. What roll looks like in equirectangular projections The following posts detail my attempt to try and estimate roll in photos taken on GoPro 360 cameras (or any 360 camera where limited metadata is written into the photos). In an attempt to try an level the horizon of my 360 photos I need to be able to determine the camera roll, however, lat, lon, and alt values cannot be used to do this. I’ve talked previously about calculating rough values for heading and pitch when other sensor telemetry is not available by working out the heading and the pitch to the next photo in a photo sequence (using latitude, longitude, and altitude). values set.Īll that being said, GoPro 360 Cameras do not include any information in photos beyond GPS positional information ( lat, lon, and alt). values will be offset from the XMP-GPano:Pose. ![]() values are set, the respective XMP-GPano:InitialView. values entered will be offset from 0 (its default value if none set). values are not set, the XMP-GPano:InitialView. considers the real world heading, pitch, or roll (and not the viewer). values, but have no relation to the actual heading, pitch, or roll in the real world. Any value (in degrees) set for these fields will offset the viewer from corresponding XMP-GPano:Pose.
