Chevelon Canyon Bridge
Here is my Chevelon Canyon Bridge entry. The Chevelon Canyon Bridge is located in Navajo County, Arizona USA. It is a Pony truss bridge spanning of the over Chevelon Creek and was built-in 1913. It has a total length of 102.7 ft (30.3 M). The bridge is posted in the National Register of Historic Places. It is still in operation today but only sees an average of 36 vehicles/day.\
This bridge has been on my bucket list for bridges to scan. I first found out about it through the bridgehunter.com website and thought that it would make a great 3D model. I drove over 800 kilometers to get the images and only had 3 hours to do it. The model did not come out as well as planned due to the bridge being freshly painted with a shiny high gloss black paint and the 30+ Km/h winds. UGH! I plan to revisit in the future with more time to capture the bridge trusses better.
A DJI Phantom 4 Pro drone was used to capture the 1800+ 20MP images using a combination of free-flight mode, point of interest mode, and Pix 4D’s capture app for the image acquisition. The captured images were pre-processed using Photoshop Lightroom using the following adjustments:
- Decrease the highlights -90
- Increase the shadows +90
- Decrease white level so that there is no clipping of the highlights
- Increase black level so that there is no clipping of the shadows
- Increase clarity to 25
- Increase vibrancy to 20
- Increase saturation to 5
- Increase sharpening slightly
- Masking increased to prevent sharpening of the highlighted areas
The images were exported and added to Reality Capture and processed in High Detail mode. Overall processing time 2d 06h:49m:51s
