A self-positioning dual-band laser interaction system

Abstract

This invention discloses a self-positioning dual-band laser interaction system, comprising a smart pointing remote control, a 2.4G USB receiver, and a host / home appliance. The remote control integrates dual cameras, a dual-band laser module, an edge-side NPU, a 2.4G module, and an infrared learning circuit. During the initialization phase, target recognition, homography mapping establishment, and receiver binding are completed. In the normal phase, the RGB camera is turned off, with only visible light laser pointing. When a button is pressed, infrared positioning calculates normalized coordinates and sends them to the bound host. Upon boundary triggering, the RGB camera is activated to recognize new targets and switch links. During the infrared control phase, the learning circuit records and transmits signals to control traditional home appliances. This invention achieves integrated spatial interaction and home appliance control modes with zero infrastructure dependency.

Description

Technical Field

[0001] This invention belongs to the field of spatial intelligent interactive systems, specifically relating to an intelligent pointing remote control system that integrates end-side self-positioning and infrared learning functions. Background Technology

[0002] Existing interactive systems cannot simultaneously handle spatial positioning and traditional home appliance control: self-positioning solutions rely on external devices and are incompatible with infrared appliances; remote controls with infrared capabilities lack spatial pointing ability. Therefore, a unified system integrating both functions is urgently needed. Summary of the Invention

Technical Solution A self-positioning dual-band laser interaction system, characterized in that it comprises: Intelligent pointing remote control: integrates an RGB camera, a narrowband infrared camera, a first-band visible light laser module (630-670nm), a second-band infrared laser module (800-940nm), an end-side NPU, a main control unit, a 2.4G wireless module, an infrared learning and transmission circuit, a button input unit, and a power module; At least one 2.4G USB receiver: Insert it into the host's USB port to pair and bind it with the remote control; At least one host and display target (optional): run the agent program and receive coordinate instructions; The remote control is configured as follows: The initialization phase completes target contour recognition, homography mapping relationship establishment, and target-receiver binding. During normal operation, the RGB camera is turned off, and pointing indication is provided only through visible light laser. During the button trigger phase, the infrared laser and infrared camera are activated, and normalized coordinates are calculated and sent to the bound receiver. During the boundary triggering phase, the RGB camera is activated to identify new targets, and the communication link and mapping relationship are switched. Infrared control stage: External infrared signals are recorded and stored through an infrared learning circuit, and then transmitted on demand to control traditional home appliances.

[0005] 3. Preferred Solution The infrared learning circuit includes an infrared receiver, an infrared transmitter, and a decoding / driving chip; The remote control has a mode switching button to switch between "spatial interaction mode" and "home appliance control mode"; The narrowband infrared camera filter has a bandwidth of ±10nm, and the center wavelength deviates from the infrared laser by ≤5nm. All computations are performed by the edge-side NPU, without relying on external nodes.

[0006] 4. Beneficial effects Functional integration: One device can integrate spatial interaction and home appliance control without the need for additional equipment; Unified operation: Pointing and button operation adapts to both types of scenarios, ensuring a consistent experience; High compatibility: Supports mainstream infrared home appliances, with a learning success rate of >99%; Independent and controllable: The entire process is completed on the device side, with no risk of privacy leakage.
