The Realization and Comparison of Directly Fitting Method and Edge Extraction Method Used in Amending the Quantization Errors

摘要

The quantization error is one of errors in 3D measuring,the method of amending the quantization errors includes directly fitting method and edge extraction method.Analyzed the source of quantization errors and the principle to amend the quantization errors,and analyzed the simulation test of directly fitting method and edge extraction method,and compared them with each other.
