| Accuracy | How closely a 3D model's dimensions match the object's. |
| Alignment Modes | How 3D scanners keep track of an object as they scan. See Feature and Marker for more details. |
| Ambient Light | The light that comes from the surrounding environment. |
| Calibration Board | A board with irregularly placed dots to check or recalibrate a 3D scanner’s accuracy. |
| Capture Range | The area that a 3D scanner can capture in a single frame. |
| Class 1 Light | Light that is completely eye-safe for people and animals. |
| Depth Camera |
Depth cameras capture the distance and depth information of the surrounding environment in a three-dimensional space. They do this by measuring the light spread time or reflection in a scene from infrared lights or other technologies. It works out the distance information of each point in the scene to construct the 3D model of the scene. |
| Feature Tracking | A tracking alignment mode where 3D scanners use an object’s features to keep track as it scans. It’s used for objects with many distinct details and surface features. |
| Field of View (FOV) | The angular extent the cameras on a 3D scanner can see. |
| Fuse | The process of merging multiple raw 3D data sets (aka frames) created during the scan into one complete Point Cloud that’s ready for meshing or editing. |
| Frame | The area that a 3D scanner can see and capture. |
| Frames | 3D surfaces captured during a scanning session, collectively constituting a scan. The scan rate varies with scanner type. |
| Frames per Second (FPS) | The number of frames a 3D scanner can capture in one second. |
| File Format |
In a computer, a file format, also called a file extension, is the layout of a file -- in terms of how the data within the file is organized. Revopoint products' output file formatsare as follows: Point cloud models can be exported in PLY, OBJ and ASC formats. Mesh models can be exported in PLY, OBJ, STL, FBX, GLTF and 3MF formats. Texture models can be exported in PLY, OBJ, FBX and GLTF formats. For details of each file format, refer to the "File Formats" section. |
| Marker Tracking | A tracking mode where the 3D scanner tracks markers placed on or around. |
| Marker Points | Small round stickers that are usually placed on or around flat featureless surfaces so a 3D scanner can use them as reference points to keep track. |
| Merge | The process of combining separate, partial 3D scans of an object to create a complete 3D model. |
| Meshing | The process of converting a Point Cloud into a 3D model. |
| Meshes | The surface geometry of a 3D model comprises a series of vertices, edges, and faces. |
| Model | The 3D object that results from the fusion operation (in Revo Scan) or another modeling process in a different software package. |
| Noise | Noise is the random variation of surface points that do not represent the true geometry of the scanned object. |
| Point | A single point in space that has been measured and recorded as part of a 3D point cloud. |
| Point Cloud | A cloud of tiny points plotted in a 3D space. Each point represents an area of an object’s surface captured by a 3D scanner. |
| Point Distance | The distance between the points in a Point Cloud. The smaller the space between the points, the higher the resolution of the point cloud. |
| Polygons | Flat geometric shapes with at least three internal angles (i.e., a triangle). Polygons are the building blocks for most 3D models. |
| Precision | A 3D scanner's ability, over repeated scans, to provide measurements close to one another. Usually specified as the nominal or maximum possible difference betweentwo measurements of the same item. |
| Project | An album including the scanning configuration, raw data, processed data, and operation history. |
| RGB Camera | A conventional color camera that captures and saves image information by recording the red, green, and blue colors of the light reflected or transmitted by the surfaceof an object. |
| Resolution | The level of detail or precision in capturing and representing the surface geometry of a 3D object. It is a measure of how finely the scanner can distinguish and capture small features, textures, and intricate details on the scanned object. |
| Scan | A sequence of frames captured in a single continuous scanner movement around an object or scene. |
| Scanning Speed | Typically listed as frames per second (fps) or points per second, this is how fast a scanner can collect data per second during a scan. |
| Scanning Spray | An aerosol used to lightly coat the surface of dark, shiny, or transparent objects to help 3D scanners see them. It can be purchased or made from everyday materials. |
| Single-frame | Also referred to as a frame. It’s the area that a scanner can see and capture in one frame. |
| Structured Light | A high-resolution, patterned light that deforms when hitting an object's surface and allows 3D scanners to capture surface information through its depth cameras. |
| Tracking | Synchronizing frames of scanning data so they are mapped to a location in 3D space that is consistent with previous frames. |
| Texturing | Applying color data captured during a 3D scan that is aligned with the mesh and applied to the model, usually as a photographic image. |
| Vertices | X, Y, and Z coordinates indicate a single point in a 3D space. |
| White Balance | White balance is a camera setting that defines the color of white. It's also called color balance or illuminant correction. White balance adjusts images so that white subjects appear white in the final product. It establishes a baseline from which all other colors are measured. |
| Working Distance | The minimum and maximum distance a 3D scanner will capture data when scanning an object. |
