3D mesh of entire cities or objects as small as a Lego brick are generated using the same photogrammetry technique: 3D measurements are derived from overlapping photographs. Those photographs can be captured from high above ground or from very close range. Each 3D mesh will have specific applications however it is also possible to combine multiple resolutions and platform into unique, seamless, multi-scale 3D mesh.
The concept behind the making of 3D models from photogrammetry is the same regardless of the size of the environment to capture: Textured 3D mesh are created from using aerial photographs captured from airplane or helicopter platforms, photogrammetry can be used to produce large area textured 3D models of whole cities and even entire regions. Smaller 3D objects such as single buildings or monuments can also be generated using drones and ground-level photographs. The same technique can be pushed even further using macro photography to create tiny textured 3D models such as individual rocks or even insects.
Those 3D mesh can be produced using a single type of camera and platform to produce a homogeneous 3D model or by combining multiple resolution and platforms into a unique, seamless, multi-scale 3D mesh.
Depending on their size and photo texture resolution, 3D mesh models can be used in a growing range of applications from smart cities, urban design, civil engineering, media and entertainment and many more.
In this presentation, we will zoom into the art and science of 3D mesh models generated from different sensors and platforms. We will explore how 3D mesh are used at their different respective scales. We will also show examples of multi-scale 3D mesh.
