Abstract: An autonomous pavement assessment system may receive depth data indicative of the depth of pixels that collectively comprise multiple defective areas of pavement. For each defective area, the system may fit a plane to it; generate a histogram that indicates the frequency of its pixels at different depths; dynamically determine a depth noise threshold for it; generate a binary image of it based on its noise threshold; and generate a depth map of it containing only the pixels that have a depth that meets or exceeds its depth noise threshold. The system may prioritize the multiple defective areas for repair and/or generate optimized rehabilitation routes. Crowd sourcing may be used to gather the depth data, as well as location information for each defective area.

Abstract: A computer data processing system may provide control information for controlling how an environmental control system controls an environment within a building. The computer data processing system may receive and store reports from multiple users and/or may receive and store reports at different times from a user. Each report may provide information concerning how the user perceives the comfort level of the user's environment at the time the user supplies the information. The computer data processing system may determine and generate the control information for controlling how the environmental control system controls the environment based on the information concerning how each user perceives the comfort level of the user's environment at the time each user provides the information.
