Abstract: A position fix identifying a geographic location of a receiver is received. The position fix was generated using signals received at the receiver from respective high-altitude signal sources (such as satellites). Imagery of a geographic area that includes the geographic location is also received. The imagery is automatically processed to determine whether one or more of the high-altitude signal sources were occluded from the geographic location when the position fix was generated. In response to determining that one or more of the high-altitude signal sources were occluded from the geographic location when the position fix was generated, the position fix is identified as being potentially erroneous.

Abstract: The present disclosure is directed to methods and systems for generating a geodetic datum. The geodetic datum can establish a coordinate system and/or a set of reference points that describe the respective locations of a portion or all of Earth and/or objects located thereon. In general, a computing system can generate the geodetic datum using various sensor data from one or more sources including: satellite imagery, aerial imagery, aerial light detection and ranging data (LIDAR), ground-level imagery, ground-level LIDAR, and/or other forms of sensor data. This data can be used as a reference dataset that can be combined with additional sensor data (e.g., a second dataset) to determine correspondences between overlapping areas represented in the datasets. Continuing this process for regions that collectively cover the Earth can be used to create a geodetic datum of the entire Earth, without using a mathematic abstraction of the Earth surface.

Abstract: A camera system includes a monochrome camera, having a global shutter, to capture a first image of a scene, and a color camera, disposed separately from the monochrome camera and having a global shutter, to capture a second image of the scene. The second image is aligned to the first image and color information of the second image is provided to the first image to obtain a third image representing the scene.

Abstract: An image capture system includes a light detection and ranging (LIDAR) device which captures images of an environment while rotating and a plurality of cameras, disposed separately from the LIDAR device, each including a rolling shutter sensor and each capturing images of the environment. The plurality of cameras include a first camera disposed to face in a first direction and a second camera disposed to face in a second direction. A time at which the first camera captures a first image is synchronized with a time at which the LIDAR device captures a second image when the LIDAR device rotates to face in the first direction, and a time at which the second camera captures a third image is synchronized with a time at which the LIDAR device captures a fourth image when the LIDAR device rotates to face in the second direction.
