Mobile Mapping Systems (MMS) Land collect data for mapping routes and provide data for geographic information systems. They integrate digital imaging sensors, navigation and positioning embedded, thus they collect data for mapping streets and avenues of the cities and allow georeferencing this information with speed, efficiency and resource economy. One of the applications of a MMS is the georeferencing of interest points such as shops, banks etc. However, there are situations where vehicular traffic is not allowed and georeferencing has to be done manually. This paper presents an application for the detection and recognition of logos, such as large commercial and georeference logos recognized automatically using the resources of a mobile device. Were used SIFT and RANSAC algorithms for detection and recognition of the logo in an image taken from the camera of the mobile device and for the georeferencing was used GPS from mobile device. The results of the experiments show that it is possible to use a mobile device to perform the georeferencing of interest point where the MMS cannot to traffic. |
