1.Accurate Positioning: With good accurate positioning ability, it can provide the scanning machine with precise reference benchmarks in threedimensional space. No matter how complicated the shape of the object surface is, the marking point can stabilize the positioning function. 2.Stability: Made of special materials, the marking point will not shift its position or degrade its performance during the scanning process due to changes in its own characteristics, and it always maintains a stable working state, providing a reliable guarantee for the scanning work. 3.Reduce errors: Through reasonable layout and precise design, it can optimize the scanning data acquisition process and reduce the accumulation of errors caused by various factors. In the data processing stage, the marking points can be used as reference points to assist the algorithm for error correction. 4.Clear and easy to recognize: Its color or shape is carefully designed to contrast with the surface of the object being scanned, making it easy for the scanning machine to capture it quickly. Even under poor lighting conditions or complex surface colors, the markers are still clearly visible.
