Abstract EN
Depth measurement is a challenging problem in computer vision research.
In this study, we first design a new grid pattern and develop a sequence coding and decoding algorithm to process the pattern.
Second, we propose a linear fitting algorithm to derive the linear relationship between the object depth and pixel shift.
Third, we obtain depth information on an object based on this linear relationship.
Moreover, 3D reconstruction is implemented based on Delaunay triangulation algorithm.
Finally, we utilize the regularity of the error curves to correct the system errors and improve the measurement accuracy.
The experimental results show that the accuracy of depth measurement is related to the step length of moving object.
