The invention discloses a 3D laser steel rail profile detection method and system based on space-time calibration. The 3D laser steel rail profile detection method comprises the following steps: acquiring steel rail profile image data by using a 3D laser scanner; performing space-time calibration on the acquired steel rail profile image data to obtain corrected steel rail profile data; substituting the corrected steel rail profile data and the standard steel rail profile data into the trained profile detection model to obtain a profile damage score; and judging the rail damage condition according to the profile damage score. According to the 3D laser steel rail profile detection method, a 3D laser scanner is used for collecting steel rail profile image data, space-time calibration is conducted on the collected steel rail image data, then operation is conducted to obtain a profile damage score, and the steel rail damage condition is judged according to the profile damage score. Whether the profile has defects is not required to be judged manually in the whole process, and the method has the advantages of high precision and high detection efficiency.
