Here’s my newest project.
There is no blueprint available for this concept car, so I searched for a new method trying to be accurate from reference pictures.
What I’ve come up with is using insight3d, a Free Software capable of doing 3D model from a set of pictures. From the focal length of each picture, and being given a set of common points (e.g. the ends of body edges) it can compute the location & orientation of cameras in 3D space for each picture, and therefore put all the common points in 3D (triangulation from the pictures)
It’s a quite robust method : spotting a point on a picture may not be very accurate, but as I use many pictures, there is a reliable, average position which can be determined. I currently use 9 picture, and will add more for front and rear ends of the car. Adding a picture is easy, you just have to place some of the points you placed on previous pictures to locate the camera in 3D space.
I’ve located about forty points so far, many more to do. It’s a long long way but then the workflow is quite simple : export the camera location and points cloud to my favorite 3D package, then use that to create spline cage. Later, as reference pictures are located in 3D space, modeling can be performed directly on top of the refpics.
My progress is quite low at the moment, so only one screenshot from insight3d attached. But I thought it’s still worth posting because I wanted to hear about your own strategies for using such a software.
