High-precision measurement system and method for pose of six-degree-of-freedom parallel mechanism

A high-precision measurement system for the pose of a six-degree-of-freedom parallel mechanism, comprising:

• a laser emission standard, which is arranged on a top of a parallel mechanism fixed platform;
• an array light spot feature target component, which is arranged above the laser emission standard;
• a parallel mechanism moving platform, wherein the array light spot feature target component is arranged at a bottom of the parallel mechanism moving platform, and a top of the array light spot feature target component is fixedly connected to the bottom of the parallel mechanism moving platform;
• the four corners of the bottom of the parallel mechanism moving platform are fixedly connected to the top of the parallel mechanism fixed platform via a six-degree-of-freedom parallel mechanism structure;
• a feature detection and recognition component, which is arranged at a bottom of the array light spot feature target component, and a detection end of the feature detection and recognition component is oriented toward the array light spot feature target component;
• the feature detection and recognition component is used to recognize the light spot information and target feature information on the array light spot feature target component.
