Abstract: Systems, devices and methodologies for generating a vehicle identification hash value and verifying the integrity of the vehicle. The vehicle identification hash value is generated based on hashes provided by each vehicle component. The generated overall vehicle identification hash value may be dynamic and reflects changes that occur to the vehicle at the component level.

Abstract: Technologies and techniques for determining locations of a plurality of markers on a vehicle in three-dimensional space. The markers may be configured as optical or radio markers, where a sensor determines the locations of each of the plurality of markers, or a shape formed by the markers collectively. The locations of each of the plurality of markers or shape is then compared to a template to determine a match. The match identifies a vehicle having vehicle data that includes locations of vehicle components and/or vehicle performance characteristics. The vehicle data is then used to generate control signals for controlling a control device that may be associated with a robotic apparatus, a vehicle computer system and/or drone operating system.
