How can I improve the accuracy of the models scanned by laser 3d scanner?

I own an infra laser 3D scanner with two receiving lenses. It uses structure light technology. I try to scan many objects and scan many times, but the models exported from the [url=https://shop.revopoint3d.com/products/pop-3d-scanner]3Dscanner are not very well. How to improve the accuracy of the models?
