The device has a 3D resolution of as high as 0.1 mm and a point accuracy up to 0.05mm. Spider is a 3D handheld, color scanner, released in 2013, designed to capture smaller, complex objects with high resolution and accuracy. Eva does not require a warm up period and can be used immediately upon powering on. Data can be exported as OBJ, PLY, WRL, STL, AOP, ASCII, PTX, E57, or XYZRGB files types. Eva can operate at distances between 0.4 m and 1 m from the object, capturing up to 16 frames per second. The device has a scan area of 214 x 148 mm at its closest range and 536 x 371 mm at its furthest, a 3D resolution of up to 0.5 mm and a 3D point accuracy of 0.1 mm.
The scanner was designed for the capture of medium to large objects. Hardware EvaĮva is a handheld, color scanner, released in 2012, that can capture and process up to two million points per second. The choice of light does not impact the processes or concepts behind the technology. Light scanners can utilize either blue light or white light, which is what Artec’s scanners use. The three-dimensional coordinates obtained are used to digitally reconstruction the real-world object. By projecting a grid pattern on the object, the scanners are able to capture the deformation or distortion from multiple angles and then calculate the distance to specific points on the object using triangulation. They operate by projecting light in a pattern, usually in the form of multiple parallel beams, onto an object. Artec’s 3D scanners are structured light scanners. 3D scanners capture the geometry of an objects and produce a three-dimensional digital model.
