Photogrammetry

The Photogrammetry room can be launched from Quick start menu

To start ensure that all the necessary conditions for Photogrammetry to work correctly are met.

Photogrammetry Left Tool Panel

• Transform: Transform the object as an entire. Click on the object to transform. Choose a rectangle or lasso mode to select multiple objects at once and transform them. Use SHIFT, CTRL CRTL+SHIFT to add, subtract or intersect selection.

• Photogrammetry tool: Аutomatic Image-based 3D reconstruction tool from images.

3DC use external library of software for photogrammetry processing: Image-based 3D reconstruction are based on Colmap and Reality Capture.

Reality Capture engine

• Video to 3D: Extract sharp frames from a video and create a 3D model from them.
  3D Coat, unlike Reality Capture, selects the sharpest frames rather than just any at the same time interval, but this process should take several minutes.
• Shots to 3D: Make a 3D model from photos. Once the process is finished a popup panel ask to increase or not the texture resolution for better reconstruction.

– Import Project: Create a new object linked to an existing photogrammetry project.
– Bake UV Textures: Bake texture from source photos into PPP model.
The PPP model must match the transform with the associated photogrammetry project.

Colmap engine

Аutomatic reconstruction tool that simply takes a folder of input images and produces a sparse and dense reconstruction in a workspace folder.
The output is written to the workspace folder.
For example, if your images are located in path/to/project/images, you could select path/to/project as a workspace folder.

• Point Cloud tool: Use this tool to create meshes from the point clouds and convert the LAS point cloud to 3D TIN file.

Photogrammetry Basics: This course is an introduction to photogrammetry. The sections within this course discuss the core principles of photogrammetry.

An Introduction to Photogrammetry

Digital space has evolved from pixelated representations of real-world objects to exact photorealistic digital copies.
The methods to create digital objects and scenery has evolved as well.
To design a single realistic digital object of life-like quality often requires hours and hours of modeling and texturing.

What if there was another way? What if the object could instead be scanned into the computer, capturing its exact shape and texture?
