针对传统最佳三条纹相位展开方法需采集12幅相移图才能获得一帧三维重建图、测量效率低下无法适应动态场景测量的问题,提出一种基于条纹复用的改进最佳三条纹方法。通过对条纹图的重复使用,使方法每新增一组四步相移图即可多获得一帧三维重建图。实验验证表明,未改进前可恢复出M帧三维重建图使用此方法后不需额外增加条纹图可恢复3M-2帧三维重建图,并且对运动误差进行补偿,对标准球杆进行测量,球A半径测量的RMSE为0.0259mm
球B半径测量的RMSE为0.0242mm。
To address the issue that the traditional optimum three-frequency fringe phase unwrapping method requires 12 phase-shifted images to obtain one frame of 3D reconstruction
resulting in low measurement efficiency and inability to adapt to dynamic scene measurement
an improved optimum three-frequency method based on fringe reuse is proposed. By reusing fringe patterns
the proposed method enables obtaining one additional frame of 3D reconstruction for every newly added set of four-step phase-shifted images. Experimental verification shows that while the unimproved method can recover M frames of 3D reconstruction
the proposed method can recover 3M-2 frames without requiring additional fringe images. Furthermore
motion error is compensated
and measurements of a standard ball bar demonstrate that the RMSE for Ball A radius measurement is 0.0259 mm
and the RMSE for Ball B radius measurement is 0.0242 mm.
