A lighting control system and method for intelligent adjustment according to different application scenarios

Abstract

The invention provides an illumination control system and an illumination control method intelligently adjusted according to different application scenarios. The system comprises an image acquisitionunit, a main processor and a relay, wherein the image acquisition unit, the main processor and the relay are in communication connection. The relay is controlled by the main processor. The system further comprises a plurality of illuminating lamps electrically connected with the relay. The main processor identifies a preset important joint point of a human body in video data based on a human bodyposture estimation algorithm, determines the specific position of each person based on a coordinate system of a space, and marks the number of persons. The main processor substitutes the above identification result into a coordinate system of a to-be-identified area, judges whether the identified number of persons is greater than a preset value or not, and adjusts the on / off state of a corresponding illuminating lamp based on the on / off signal of the control relay. According to the invention, the specific number and the specific positions of persons which frequently change in a classroom, an office space and other indoor places can be accurately identified. The electric power is effectively saved, and the energy waste is avoided.

Description

technical field [0001] The invention relates to the field of artificial intelligence, in particular to a lighting control system and method for intelligent adjustment according to different application scenarios. Background technique [0002] At present, the mainstream intelligent human body sensor lights on the market are human body infrared sensor lights and radar lights. [0003] The main device of the human body infrared induction lamp is the human body pyroelectric infrared sensor. When a person or an object with temperature enters the sensing range of the module, the sensing module will output a high-level pulse signal or a high-level delay signal, and the output induction pulse or delay signal can directly drive the LED indicator light, LED lights. The disadvantage of this kind of lamp is that when the ambient temperature is close to the human body temperature, the detection and sensitivity will drop significantly, and sometimes even short-term failure occurs, so it...

AI Technical Summary

Problems solved by technology

The disadvantage of this kind of lamp is that when the ambient temperature is close to the human body temperature, the detection and sensitivity will drop significantly, and sometimes even short-term failure occurs, so it is not suitable for use in rooms with heating or heating and air conditioning; Poor, when the infrared radiation of the human body is blocked by other objects, it is not easy to be received by the probe, and sometimes there will be a phenomenon that it cannot be sensed

Existing detection methods and light control systems have certain limitations
