Abstract: Methods, systems, and computer program products are provided for determining camera parameters and three dimensional locations of features from a plurality of images of a geographic area. These include, determining a correlation between a pose of a first camera and a pose of a second camera, generating one or more constraints incorporating the correlation, and determining at least one of camera parameters and three dimensional locations of features using a plurality of constraints including the generated one or more constraints. The first camera and the second camera have substantially rigid positions and poses relative to each other. A strength of the correlation is based at least upon a time interval between respective image captures by the first camera and the second camera.

Abstract: The present invention pertains to geographical image applications. A user may transition between nadir and street level imagery using unstitched oblique imagery. Oblique images offer a rich set of views of a target location and provide a smooth transition to or from other images such as nadir photographs taken by satellites or street level photographs taken by ground level users. Using unstitched oblique images avoids artifacts that may be introduced when stitching together one or more images. This allows an application to display images to a user and create the illusion of three dimensional motion.
Abstract translation: 本发明涉及地理图像应用。 用户可以使用未标注的倾斜图像在天底和街道级图像之间切换。 倾斜图像提供了丰富的目标位置视图，并提供平滑过渡到其他图像，例如卫星拍摄的天底照片或地面用户拍摄的街道照片。 使用未缝合的倾斜图像避免了在将一个或多个图像拼接在一起时可能引入的伪像。 这允许应用程序向用户显示图像并创建三维运动的幻觉。

Abstract: Embodiments relate to selecting textures for a user-supplied photographic image in image-based three-dimensional modeling. In a first embodiment, a computer-implemented method includes a method for inputting a user-supplied photographic image that uses a photogrammetry algorithm to adjust a plurality of camera parameters for the user-supplied photographic image. In the method, a user-supplied photographic image inputted by a user is received. A set of geographic characteristics inputted by the user that correspond to a geographic location of a camera that took the user-supplied photographic image is received. A plurality of camera parameters that correspond to the geographic location of the camera that took the user-supplied photographic image is determined. The user-supplied photographic image to be texture mapped to the three-dimensional model is enabled.

Abstract: Embodiments relate to evaluating structures located in a geographic area that is divided into divided bounding areas using a three-dimensional environment representing the structures. In an embodiment, a computer-implemented method includes a method for dividing a three-dimensional environment depicting the structures into the divided bounding areas where each divided bounding area encompasses a portion of structures. In the method, an evaluation web page for each divided bounding area is retrieved from a structure evaluation server where each evaluation web page provides an evaluation status for each divided bounding area. At least one structure encompassed by a selected divided bounding area is evaluated based on a visual representation of the structure. An updated evaluation web page for the selected divided bounding area is provided to the structure evaluation server where the updated evaluation web page provides an updated evaluation status for the selected divided bounding area.

Abstract: Systems and methods for generating textures to be rendered in conjunction with a polygon mesh are provided. More particularly, a polygon mesh modeling a geographic area can be accessed. A plurality of source images depicting the geographic area can then be identified. The plurality of source images can be aligned to reduce projection misalignments between source images when the source images are projected to the polygon mesh. A texture can then be determined based at least in part on a weighted average of pixels in the plurality of source images corresponding to a point on the surface of the polygon mesh. Determining a texture can include removing at least one outlier pixel associated with a moving object from the weighted average.
