摘要: 基于全景影像的街景立面管理中,需要跳转至距离目标面最近且尽量正对目标面的全景影像,但常规的全景影像跳转方法并不能满足这一需求,为解决该难题,本文提出了一种新的全景影像探面及跳转方法。基于全景影像的景深图,计算目标点的世界坐标及该点与邻近点组成面片的平均法向,实现全景影像中的探面;从目标点出发,沿平均法向搜索出视点中心与该射线垂直距离最近的全景影像;切换至目标影像,并根据目标点在目标影像中的方位进行视角旋转。在重庆市实际项目中的成功应用及实例分析结果均表明,本文方法能够满足立面管控需求,更好地切换至正对目标立面的邻近全景影像,应用效果较常规跳转方法有较大提升。

Abstract: In the management of street view facades based on panoramic images, it is necessary to jump to the panoramic image that is closest to the target facade and face it right at the front as much as possible. However, the conventional jumping methods cannot meet this demand. To solve this problem, a new method of plane detecting and jumping for panorama images is proposed. Based on the scene depth image of the panoramic image, calculate the world coordinates of the target point as well as the average normal direction of the patch formed by the target point and its neighboring points, so as to achieve the plane detection in the panoramic image. Starting from the target point, search along the average normal direction for the panoramic image whose viewpoint is the closest to the ray. Switch to the target image, and rotate the angle of view based on the orientation of the target point in the target panorama image. The successful application in practical projects in Chongqing and the case study results show that the proposed new method can meet the requirements of facade management and jump to the better neighboring panoramic image facing the target facade. The application effect of the new method is also better than that of conventional jumping method.

Key words: panorama image, plane detection, scene depth image, building facade management, mobile mapping
