Wireless 3D scanning: what matters on site

Message summary

What happened

Shilin 3D released the FreeScan Trak Nova wireless multi-functional dynamic tracking scanning system on February 18, 2025. The official introduction integrates tracking scanning, handheld laser scanning and video photogrammetry functions into the same system for three-dimensional measurement tasks of different scales. This article discusses its technical direction and does not constitute a recommendation for specific equipment procurement.

Co-creator observation: Site conditions determine preparation work

Physical size, surface condition, mobility and occlusion position will all affect the acquisition scheme. After arriving at the site, it was discovered that the parts could not be turned over, or the key mating surfaces were covered, which would directly affect data integrity. Therefore, it is best to provide physical photos, size range and on-site space conditions in advance.

For areas such as reflections, deep holes or thin edges, it is necessary to individually judge whether the data can be reliably obtained. A surface that appears continuous on the monitor cannot be taken to mean that all details have been accurately captured.

From scan results to usable models

The scanned mesh usually needs to be organized and modeled according to the purpose. If the goal is to produce engineering drawings, modify structures, or reprocess, the delivery file format, geometric relationships that need to be retained, and acceptance methods should be determined first. Just saying "give a 3D file" is often not clear enough.

We recommend that the original collection, processed data and final delivery model be saved separately, and the processing process be explained. During customer acceptance, in addition to checking the overall appearance, key dimensions, benchmarks and assembly relationships should also be checked so that the data can truly support the next step of research and development.
