Pandemic Pop-Up - Image Capture Workflow
Pandemic Pop-Up – Image Capture Workflow for 3D Modelling Background (for those interested in the process – skip if not interested) Photogrammetry is the process I use to create these types of models. It involves taking numerous photographs of an object from many angle. These images are then fed into the model building software. Essentially what the software does is take a photograph, identify features that it believes to be unique in the photo and then try to find those same features in the other photos in the set. Once it has identified the same features in multiple photographs it can calculate the change in the relative distances between feature points between photographs. With this information the program can determine where the cameras were in space relative to the object when the photographs were taken and build a cloud of points that represents the shape of the object. From there its basically a matter of playing connect the dots with the point cloud to create a surface ...
