Photogrammetry bundle adjustment optimization method based on T-MAC

The invention discloses a photogrammetry bundle adjustment optimization method based on T-MAC, wherein the method comprises the following steps: S1, selecting a CAD model design coordinate system of a to-be-measured part as a base coordinate system, building a conversion relation between each measurement coordinate system and the base coordinate system, calibrating a photogrammetry image space coordinate system, and unifying measurement results under the base coordinate system; s2, controlling a robot to drive a camera to shoot around the to-be-detected component at multiple angles, extracting image point coordinate information in a photo, and listing a collinear equation and a corresponding error equation; s3, recording the pose parameters of the T-MAC under different camera stations, solving the external parameters of the camera under the base coordinate system through the calibration result of the coordinate system, and establishing a constraint equation; s4, adjusting and integrally solving the three-dime
