地标搜索对于提升旅游体验质量至关重要。智能手机可以随时随地搜索地标。大多数现有的工作计算图像特征的智能手机本地后,采取的地标图像。与将原始图像发送到远程服务器相比,发送计算特征节省了网络带宽,从而使发送过程快速。然而,该方案会受到手机电池电量和计算能力的限制。在本文中,我们建议发送压缩(低分辨率)图像到远程服务器,而不是计算本地的地标识别和搜索的图像特征。为此,提出了一种鲁棒的基于3D模型的方法来识别具有相应地标的查询图像。使用所提出的方法,低分辨率的图像可以准确地识别,即使图像只包含一小部分的地标或在各种条件下的照明,缩放,遮挡和不同的观点。为了提供有吸引力的地标搜索结果,生成3D纹理模型以响应地标查询。所提出的搜索方法,这开辟了一个新的方向,从一个2D压缩图像查询输入和3D模型搜索结果结束。
Landmark search is crucial to improve the quality of travel experience. Smart phones make it possible to search landmarks anytime and anywhere. Most of the existing work computes image features on smart phones locally after taking a landmark image. Compared with sending original image to the remote server, sending computed features saves network bandwidth and consequently makes sending process fast. However, this scheme would be restricted by the limitations of phone battery power and computational ability. In this paper, we propose to send compressed (low resolution) images to remote server instead of computing image features locally for landmark recognition and search. To this end, a robust 3D model based method is proposed to recognize query images with corresponding landmarks. Using the proposed method, images with low resolution can be recognized accurately, even though images only contain a small part of the landmark or are taken under various conditions of lighting, zoom, occlusions and different viewpoints. In order to provide an attractive landmark search result, a 3D texture model is generated to respond to a landmark query. The proposed search approach, which opens up a new direction, starts from a 2D compressed image query input and ends with a 3D model search result.
