In the traditional leveling data processing operation,the information of leveling staff verification certificate is read manually,which restricts the realization of full process automation of leveling data processing. This paper recognizes the text information in the picture of leveling staff verification certificate bases on Paddle OCR model,arranges the block recognition results in rows,extracts the key information after data cleaning,context contract and information complementary verification,and realizes a picture text automatic recognition method for a large number of leveling staff verification certificates. The accuracy of the recognition method is 98.7％. It can replace the role of calculator in engineering application,and provide technical reference for realizing the cross integration of artifi-cial intelligence technology and surveying and mapping geographic information specialty,and provide technical reserves for the future development of intelligent unmanned leveling data processing software as well.
