Three-dimensional modeling scanner

A method for constructing a three-dimensional (3D) modeling scene, the method comprising:

• capturing a first image using a first camera and a second image using a second camera, wherein the first image comprises a first coded target and the second image comprises a second coded target;
• determining a first camera characteristic set based on the first image and the first coded target,
• determining a second camera characteristic set based on the second image and the second coded target;
• generating, based on the first camera characteristic set and the second camera characteristic set, one or more scene characteristics;
• and
• storing the one or more scene characteristics as the 3D modeling scene, wherein
• each of the first and second coded targets that are captured comprises:
• patterns selected from a group consisting of:
• a concentric circle pattern, a binary dot pattern, and a character;
• and
• visible lines that do not intersect, that separate the patterns and that extend in both dimensions of the coded target.

A system for generating a three-dimensional (3D) model of a target object, the system comprising:

• an enclosure;
• a plurality of cameras disposed around the enclosure;
• and
• a model generation server, wherein
• the plurality of cameras capture, using one or more image capture settings, a plurality of two-dimensional (2D) images each including a coded target and at least a portion of the target object,
• the plurality of cameras transmit the plurality of 2D images to the model generation server,
• the model generation server generates the 3D model of the target object and one or more model characteristics of the 3D model based on the plurality of 2D images, and
• the coded target that is captured comprises:
• patterns selected from a group consisting of:
• a concentric circle pattern, a binary dot pattern, and a character;
• and
• visible lines that do not intersect, that separate the patterns and that extend in both dimensions of the coded target.
