Abstract: A method and apparatus for controlling an unmanned device, a storage medium, and an electronic device are provided. In some embodiments, not only a control policy is determined according to a single frame of a current image, but a safety representation value of an unmanned device at a current moment and safety representation values of the unmanned device at respective historical moments are respectively determined according to a current image and environment images of several historical moments. In those embodiments, a control policy of the unmanned device at a next moment is determined according to a safety representation value of the unmanned device at current moment and the safety representation values of the unmanned device at respective historical moments.

Abstract: The disclosure provides a multi-level occupant movement simulation method and apparatus. The method includes: establishing a multi-level architectural topology according to a structure of a building; obtaining a schedule of multiple occupants in a simulation experiment; obtaining a time period of stay of each occupant of the multiple occupants according to the schedule, and simulating, according to a preset simulation algorithm, the state transition position of each occupant in the multi-level architectural topology during the time period of stay; and calculating an operating energy consumption parameter of the building according to the state transition position.

Abstract: A wearable device and a method for displaying an evacuation instruction are provided by embodiments of the present disclosure. The wearable device includes an eyeglass frame; a camera, configured to capture a current scene; an eyeglass lens with a display screen; a rotating vector sensor, configured to acquire a current horizontal orientation angle; a geomagnetic sensor, configured to acquire a current geomagnetic deviation angle; and a processor.
