Abstract: An apparatus and a method image classification based positioning are provided. For image-based positioning to predict a camera pose from image data, a positioning apparatus obtains a prediction result indicating which cell the image data belongs to among cells constituting a space for positioning from a classification network that processes the image data based on a pre-learned weight. The positioning apparatus obtains map information on the space for positioning by using a cell index selected based on the prediction result, and the map information includes minimum and maximum values of coordinates constituting a cell for each cell index, and a cell size. A position of the image data based on the map information is calculated to output a corresponding camera pose.
