  • Patent number: 11676395
    Abstract: Automated capture of image data for points of interest may be implemented for points of interest in an environment external to a vehicle. Sensors implemented as part of a vehicle may collect sensor data for an environment. Processing of the sensor data may be performed to detect points of interest in the environment. In response to detecting a point of interest, image data may be captured by one or more of the sensors implemented at the vehicle. Different types of image data may be captured, such as panoramic images and three-dimensional reconstructions of a scene. Metadata may be generated for captured image data which may describe the point of interest that is captured by the image data. The image data and the metadata may be stored locally at the vehicle or to a remote data store. The image data may also be shared with other computing devices.

  • Patent number: 10879952
    Abstract: Apparatuses and methods for decoding a spreading code-encoded signal. The decoder decodes a spreading code-encoded signal by performing a synchronization search to determine a synchronization point. The synchronization point defines a time delay for aligning a spreading code, which was used to generate the spreading code-encoded signal, with the spreading code-encoded signal. The synchronization search includes obtaining candidate results, where each candidate result is a decoding attempt that applies a time delay for aligning the spreading code with the spreading code-encoded signal. The synchronization search also includes determining the synchronization point by identifying the time delay corresponding to the candidate result that is associated with a power measurement that satisfies a synchronization search criterion. A decoder code synchronization is performed to align the spreading code with the spreading code-encoded signal, using the synchronization point.

  • Patent number: 10671068
    Abstract: Sensor data captured at by different sensors may be shared across different sensor processing pipelines. Sensor processing pipelines may process captured sensor data from respective sensors. Some of the sensor data that is received or processed at one sensor data processing pipeline may be provided to another sensor data processing pipeline so that subsequent processing stages at the recipient sensor processing pipeline may process the combined sensor data in order to determine a perception decision. Different types of sensor data may be shared, including raw sensor data, processed sensor data, or data derived from sensor data. A control system may perform control actions based on the perception decisions determined by the sensor processing pipelines that share sensor data.
