As key part of aero-engine, blade has the characteristics of huge quantity, various shapes, high processing quality requirements and complex processing. It is of great significance to develop efficient and high-precision non-contact surface size detection for blade processing and its quality detection. Optical scanning measurement based on visual tracking is becoming an effective and reliable measurement method. In order to realize the tracking of the scanning system, this paper designs a 3D stereo target, and proposes an algorithm to recognize the coded markers on the stereo target.
