摘要： Aspects of the disclosure relate generally to condensing sensor data for transmission and processing. For example, laser scan data including location, elevation, and intensity information may be collected along a roadway. This data may be sectioned into quanta representing some period of time during which the laser sweeps through a portion of its field of view. The data may also be filtered spatially to remove data outside of a threshold quality area. The data within the threshold quality area for a particular quantum may be projected onto a two-dimensional grid of cells. For each cell of the two-dimensional grid, a computer evaluates the cells to determine a set of characteristics for the cell. The sets of characteristics for all of the cells of the two-dimensional grid for the particular quantum are then sent to a central computing system for further processing.

摘要： Aspects of the present disclosure relate generally to systems and methods for assessing validity of a map using image data collected by a laser sensor along a vehicle path. The method may compile image data received from the laser sensor. The map subject to assessment may define an area prohibiting entry by a vehicle.

摘要： Disclosed herein are methods and apparatus for generating accurate maps for autonomous vehicles. A map is stored at a computing device associated with a vehicle. The vehicle can be operated in a partially-autonomous mode, where the computing device can generate driving directions for manual execution along a route based on the map. The computing device can be configured to receive and store information related to features and a quality of driving along the route. The map can be updated and quality control statistics can be determined based on the stored information. The updated map can be promoted based on the quality control statistics. In response to promoting the updated map, the computing device can store the promoted map and enable the vehicle to operate in the autonomous-operation mode using the promoted map.
