Abstract Borehole camera technology has been widely applied to various underground survey field，however，actual survey environment is often restricted by external factors and there is a difference between actual survey environment and theory survey environment，resulting in errors of the actual survey value. Therefore，according to the basic principle of borehole camera technology，we carry out the theoretical error analysis of two kinds of borehole television which may exist in the actual survey engineering and scientific research，and focuses on the systematical study when the probe is in no central of the borehole，calculating the error of fracture width，structural plane tendency，inclination and the width of structural plane on borehole wall，besides，analyzing the error influence brought by the survey speed，and giving recommendations of the survey speed. Through the above study，the conclusion can be drawn：(1) It is very small error when the probe of digital panoramic borehole camera is not in the drilling center and almost does not affect the survey accuracy and precision of the system；(2) The digital borehole camera is more accurate than axial view panoramic borehole TV；(3) The digital panoramic borehole camera system is more suitable for the investigation of structural plane；(4) The survey speed of borehole camera is suggested to be 1.5 m/min.

Key words： rock mechanics borehole camera structure plane accuracy analysis survey speed
