Abstract: A monocular high-speed videogrammetry method based on a dynamic platform includes the following steps: collecting a monocular high-frame-rate image sequence of the dynamic platform and performing preprocessing; conducting dynamic image-block data processing on the image sequence based on adaptive brightness compensation and least-squares fitting (LSF) to obtain adjusted images; performing camera-pose calibration on the adjusted images based on sliding-window constraints to obtain calibrated images; and acquiring three-dimensional (3D) coordinates and estimated displacements of tracking points from the calibrated images, and outputting measurement results based on the 3D coordinates and the estimated displacements. Through optimization of the measurement process, the method supports real-time adaptive compensation, dynamic image-block processing, and camera-pose calibration, thereby providing significant application value.
