1. An object tracking system configured to track a position of an object by using a sensor, the object tracking system comprising:
at least one memory storing instructions and a parameter related to an erroneous detection or a non-detection caused by a detection characteristic of the sensor;
at least one processor configured to execute the instructions to:
detect the position of the object by using the sensor;
track the position of the object based on the position of the object obtained by using the sensor and the parameter stored in the at least one memory;
calculate, based on the tracking result of the object, an evaluation index of the tracking result; and
determine the parameter based on the evaluation index of the tracking result calculated and update the parameter stored in the at least one memory.
