Higher angle perspective panorama of Anuenue Park in Waimea (Kamuela) Hawaii, United states. In the track record at the higher appropriate is the Parker Faculty.
This was also finished to support with the restoration do the job on Anuenue Park. It was not exclusively requested for by the organizers, but I wanted to give elevated panorama images a consider at this place to see how very well the computer software discounts with a great deal of geometrical features (really perfectly, really), and the first is a comprehensive 360 panorama that lets the viewer choose a glimpse at most of the playscape in the park from a site in space. It really is a superior indicator of the condition of the woodwork and the volume of don on the playscape as a total.
This was done making use of a 25′ painter’s pole with my comprehensive RC KAP rig suspended from the prime. It enable me do a a few-stripe panorama with the digicam held vertically, for just beneath 100 photos. I had to cull out about half of them in buy to make AutopanoPro content. Soon after that it stitched good.
I’ve uncovered if you do not have your camera rotating directly on the nodal stage of the lens, you can compensate for this to some degree by over-sampling. In its place of obtaining 25-30% overlap amongst photos, go for 60-75% overlap and have virtually each issue in the panorama sampled on at the very least three frames. This places a noxious load on the panorama software, but for SIFT-dependent computer software it seems to give supplemental clues to the stitch motor so that breaks in traces can be prevented.
In this situation I experienced to slice out my in excess of-sample pictures and vacation resort to conventional process for panoramas: 25-30% overlap. Thankfully this KAP rig does rotate the digicam very just about the nodal issue of the digicam lens, so things still operate out very well.
As a facet note, the weird stray shadow in the gravel is the pole and KAP rig. If you glimpse at the shadow of the rig by itself, the gravel is a very good deal brighter. There was a actually neat thread on this anti-sunward brightening on the KAP discussion board. I did a good little bit of gamma adjustment utilizing levels to check out to carry this down and provide up the shadowed areas in the sunward route, so the first outcome is substantially more robust. It is fewer visually distracting this way. I debated editing out the shadow of the pole and KAP rig, but resolved to depart it in.
The unique for this was above 26,000 pixels huge, and is just in excess of 2:1 part ratio. It is seriously down-sized for putting up on Flickr.
