An error correction method and an error correction device for correcting an error in movement data of an object are provided. The error correction method includes collecting sensing values corresponding to movement of the object for each data frame, based on a predetermined time interval, grouping continuously collected data frames among data frames corresponding to the collected sensing values, normalizing the sensing values based on a minimum value among the sensing values of each of the grouped data frames, using an error detection model, determining whether a previous sensing value is an error value, based on a current sensing value and the previous sensing value collected at a time earlier than the current sensing value among the normalized sensing values, and when the previous sensing value is the error value, correcting the error value based on normal values that are not the error value among the sensing values.
