摘要： A method and system comprising one or more event-based vision sensors for monitoring an environment and one or more depth sensors monitoring the environment as well as potentially additional sensors to monitor the environment such as inertial measurement units and image sensors. The device as a processor assembly will then monitor the event-based vision sensor and the depth sensor and other sensors and determine whether to adapt a control schem, such as activate, the depth sensor to acquire depth information of the environment based on the response of the event-based vision sensor. This approach leverages advantages of event-based sensors to reduce the power consumption but still react quickly to such changes by continuously measuring intervals directly relating to the minimally admitted delays in the application for which depth measurements or inferred data are used.
