Claim 0:
1. A processor-implemented method, comprising:
obtaining, using a depth network, a respective depth image for each of a plurality of successive input images obtained from a camera;
obtaining, using a pose network, respective image pose transformation matrices between images, of the successive input images, at adjacent time points;
obtaining, based on initial pose information and the respective image pose transformation matrices, image pose information for each of the adjacent times;
estimating final pose information dependent on the obtained image pose information for each of the adjacent times;
accumulating the image pose transformation matrices; and
calculating a pose loss value based on a result of comparing image position information, obtained from a result of the accumulating, and sensor position information obtained from a sensor comprising either one or both of a global positioning system (GPS) and an indoor position sensor.
