I decided to make a 3d scan of my helmet chin area and then extrude the front portion, add a custom GoPro mount by blending it into my initial extrusion and also add 2 side rectangles for the straps as shown in the pictures below:
The straps should get around into those 2 air vents from the helmet’s chin as shown in this bicycle helmet GoPro mount system:
I have generated a 3d model of the helmet’s chin area using ~ 70 pictures and Zephyr and also Instant Meshes with a 33.25 K vertex count and 2 Smooth Iterations that resulted in this 3d model that I have uploaded here: https://skfb.ly/oqFvM
Now using Blender, I have selected the area I was mainly interested in and extruded a little bit so I ended with this object:
That has been uploaded here: https://skfb.ly/oqFyL
I’ve imported this GoPro mount https://www.thingiverse.com/thing:736531/files and I’m going to merge those two by using the Sculpt Mode. Finally and hopefully I will also add the straps holders and my project will be complete.
I’m pretty much stuck now as I don’t really know how exactly should I combine my helmet extrusion with the gopro mount and the rectangular strap holes (ears) and I’m also struggling with making this whole object match the real-life dimensions so I ask you for improvements on this workflow.
Also, do you know anyone else that made and documented such a journey?
