This invention discloses a method, device, and storage medium for directional device identification and control based on vision and
spatial perception, belonging to the field of
intelligent control and human-computer
interaction technology. The method is applied to portable terminals, achieving "point-and-
shoot" by using a coaxially integrated
laser and
camera module to acquire target images containing
laser pointer spots. To address the identification challenges caused by differences in target object size and distance, the method proposes multi-scale adaptive region extraction, generating and matching multiple candidate regions centered on the
laser pointer spot. Simultaneously, to eliminate control ambiguities for similar devices in different rooms, the method innovatively utilizes smart home device nodes in known locations within the environment as
Bluetooth beacons, achieving zero-deployment-cost collaborative
spatial perception and obtaining the terminal's precise spatial location. Finally, by jointly querying and adjudicating the
visual recognition results and spatial location information, the target device is uniquely identified and control commands are generated. This invention achieves intuitive interaction with zero learning costs, solving the problems of complexity and
confusion in traditional control methods. It has advantages such as accurate identification, fast response, simple deployment, and privacy security, making it particularly suitable for smart home and smart
elderly care scenarios.
