我们展示了一个在校园户外使用的信息指南系统的原型。它允许用户使用拍照手机查找感兴趣的地方（例如演讲厅和图书馆）。我们使用由 GPS 位置标记的校园场景全景数据库，这可以减少视图之间的重叠。获取具有与查询视图最近的位置的全景视图。我们利用宽基线匹配技术来匹配视图之间。然而，由于观点的不同和重复结构的存在，很大一部分匹配可能是错误匹配。我们提出了一种验证模型来有效消除错误匹配。选择真实的对应关系进行姿势恢复，然后将信息投影到图像上。该系统经过大量实验验证，在不同季节、天气、光照条件等条件下拍摄图像。
We present a prototype of an information guide system to be used outdoor in our campus. It allows a user to find places of interest (e.g., lecture halls and libraries) using a camera phone. We use a database of panoramic views of campus scenes tagged by GPS locations, which can diminish overlapping between views. Panoramic views with the closest locations with the query view are acquired. We exploit a wide-baseline matching technique to match between views. However, due to dissimilarity in viewpoints and presence of repetitive structures, a vast percentage of matches could be false matches. We propose a verification model to effectively eliminate false matches. The true correspondences are chosen for pose recovery and information is then projected onto the image. The system is validated by extensive experiments, with images taken in different seasons, weather, illumination conditions, etc.
