The ever-expanding range of 3D scanners are a fast becoming a lynch pin of modern 3D technologies as they demonstrate the replication of any object and the efficiency of reverse-engineering various products and end-use parts.
Now RangeVision, with their Smart line of scanners, is staking their claim in this growing market. The Smart line of scanners uses structured light technology rather than lasers. Structured light works by flashing a known pattern of light across a 3D object. The resulting distortions from the expected pattern are what the device uses to drive the software, which ultimately builds a 3D model.
The RangeVision Smart shoots that pattern of structured light for 5 to 7 seconds to encode fragments of an object, and aggregating a group of those fragments permits a full 360 degree reconstruction. The company says each fragment can provide up to a million facets in a 3D mesh, and the process allows the Smart line to scan small tabletop objects – and larger objects – simply by making a series of adjustments. The accuracy of the final output increases or decreases depending on the scan volume, and accuracy from 0.085mm to 0.16mm is possible..
The scanners weigh in at approximately 0.7 kilograms and require the Windows OS and a video card.
Priced at approximately $2,600, the RangeVision Smart is priced at considerably less than professional scanners which advertise similar accuracy numbers, but it is more expensive than a growing list of 3D scanners, of lower quality.
RangeVision, the international developer and manufacturer of the Smart series, says their device includes two industrial-quality cameras of 1.3 MP and are “easy to calibrate.” The Smart line is available in three different colors and comes with a travel case. RangeVision says objects from 4 cm to 1 m in size can be fully scanned within 7 seconds, and the resulting files can be exported to STL, OBJ and PLY formats.
The RangeVision Standard scanner can capture data via the 1.3 MP cameras, features a plastic camera body and depending on the scan volume is accurate to within 0.05 mm or 0.35 mm of resolution.
The RangeVision Standard Plus also makes use of the 1.3 MP cameras and boasts similar resolution and time specs, but with a metal camera body.
RangeVision Advanced uses a pair of 2 MP cameras with 1600 х 1200 capability, a CCD matrix diagonal size of 1/1.8″, has a scan time 12 sec, a metal camera body and is capable – depending again on the volume of the object scanned – of 0.043 mm to 0.3 mm resolution.
The Smart line of scanners come fully-assembled and can operate independently of an outside power source up to one hour. The company says their user-friendly software comes with free updates and is included in the price of the scanner. RangeVision says the devices offer plug-and-play simplicity, detailed and full-color scans, and are equipped with “low-noise industrial cameras.”
