Disclosed herein are a method and apparatus for matching 3D terrain information based on aerial images captured at different altitudes. The method includes receiving a high-altitude numerical height model based on a terrain image captured at a specific high altitude; receiving 3D terrain information observed from a low altitude, which is generated based on a terrain image captured at an altitude lower than the specific high altitude; generating a low-altitude numerical height model by converting the 3D terrain information into a numerical model in the same form as the high-altitude numerical height model; measuring the cross-correlation between the high-altitude numerical height model and the low-altitude numerical height model, thereby calculating matching parameters for enabling the low-altitude numerical height model to match the high-altitude numerical height model; and adjusting the geospatial coordinates of the 3D terrain information based on the matching parameters and outputting georeferenced 3D terrain information in the same coordinate system as the high-altitude numerical height model.

Disclosed herein is an apparatus and method for interaction between content and an olfactory recognition device. In the method for interaction between an olfactory recognition device and a content device, the method allows the olfactory recognition device to interact with the content device. If a connection to the content device has been made to enable data communication with the content device, an open signal is transmitted to the content device. As a response to the open signal, an approval signal is received from the content device. A device information datasheet that is information about the olfactory recognition device is transmitted to the content device in response to the approval signal. An acknowledgement signal is received from the content device.
