Accessories: Network with position points

We also follow the current events around us, and as part of our work we came across accessories that should make life easier for 3D scanners. It won't work for us and we have to share our experience.

We already had a network with position points in our portfolio about fifteen years ago and actually used it. So we've recorded our insights from using it for you so you can decide for yourself whether it's a step forward or not.

Pros

• Ease of work, it is not necessary to stick the part with positional points.
• Financial saving (we don't have to glue the points and then throw them away).

Cons

• Almost unusable outdoors. Even a slight gust of wind is enough and the points between the holders on the fishing lines will move a little, so the scanner will start to consider them as new.
• We encountered the same problem in interiors. Sometimes it was enough to walk around the net, and the operator caused a vibration of the air with his own body, which made the positioning net vibrate. Magnetic holders would have to be put behind each point, which then loses its meaning. To close the mesh so that the fibers between the holders cannot move even a little means to use really many holders and close together.
• The acceleration of work is only theoretical. It also takes a lot of time to spread the net and anchor it properly.

The fate of this accessory

This accessory has been discontinued and discontinued. The main reasons were that after scanning it was not possible to fully guarantee the accuracy of the scan (slight network movement). In some cases, only part of the network moved, and the result was distorted only in some areas.
Even in cases where high precision is not needed, we have encountered complications, as even the slightest movement of the mesh causes the scanner to consider the position points as new combinations, and the folding of the scan subsequently does not proceed correctly, or more surfaces are created. Subsequently, it is difficult to determine which are correct and which are not, or how to merge them.

We hope that our findings will be of benefit to some users. It is certainly not our job to discourage you from using this accessory. We just want you to be aware of the risks above that come with using the network.
