Items that meet the following three conditions at the same time have the best scanning results of colors and textures:
- Matte, rich color, non-solid color, less black items;
- Items with continuous, non-repetitive, and richly varied geometric features (features alignment)/texture features (texture alignment);
- The size of the item is ≥30cm (iReal color camera has 1.3 million pixels, and the best scanning distance: 40 cm. The mapping result obtained by this pixel at this distance has limited clarity. If the item is too small, it may not be able to satisfy its mapping quality requirements).
