Embodiment Construction
[0024] The wearable device-oriented tracking and matching parallel computing method of the present invention comprises the following steps:
[0025] (1) Hybrid tracking and feature extraction technology for wearable devices;
[0026] (2) The Harris corner detection CRF optimization method improves the CRF algorithm and completes the precise extraction of feature points of natural features and unmarked targets;
[0027] (3) Realize the detection of Harris corners based on the GPU parallel process mechanism;
[0028] (4) Based on the P-KLT parallel feature tracking algorithm of CPU, the displacement deviation of feature points in two frames is given;
[0029] (5) The secondary matching optimization algorithm uses BGNCC initial rough matching and RANSAC fine matching to improve matching robustness.
