Abstract
A method of calibrating an alignment model between a first sensor that uses a radar and a second sensor that determines a position of a sensor, and an electronic device performing the method. A radar map for surroundings of the first sensor and the second sensor is generated based on the first sensor and the second sensor, and at least one object located around the first sensor and the second sensor is detected based on pre-generated data. Also, target data corresponding to the object is determined based on the radar map, an error of the target data is calculated based on a shape of the object and the target data, and the alignment model between the first sensor and the second sensor is calibrated based on the error.
