Feature

●Most software supports solid dots or squares as landmarks.
●High precision processing technology, low thermal expansion coefficient, high precision (±0.01mm).
●In the process of high-precision camera calibration, feature points are mostly used as reference points to accurately extract the center position through graph fitting.The centroid caused by projection is eliminated by known calibration template parameters.
●Good Durability: Selected high-quality materials, with good durability and stability for long time use.
●If you are not satisfied with the product, please feel free to contact us, we will provide you with quality after-sales service.
