Problems solved by technology
Then, the measurement area of each infrared sensor and the measurement area of the entire infrared array sensor will also be fixed, resulting in the resolution of the measurement area cannot be adjusted, the temperature detection of the human body in the measured area is not accurate, and it is difficult to accurately distinguish the human body. The specific parts of the body affect the accuracy of human body positioning and recognition

The present invention discloses a method and a device for enabling the adjustable resolution of an infrared array sensor. The infrared array sensor comprises a controllable deformation substrate and a plurality of infrared sensors disposed on the substrate. The method comprises the steps of judging whether a detection target exists in the detection area of the infrared array sensor or not; acquiring the current resolution of the infrared array sensor for the area of the detection target; comparing the current resolution with a preset resolution; on the condition that the current resolution is smaller than the preset resolution, controlling and driving the substrate to deform and reducing the spacing among the infrared sensors on the substrate till the current resolution is not smaller than the preset resolution; on the condition that the current resolution is not smaller than the preset resolution, keeping the substrate from deforming. According to the technical scheme of the invention, the detection resolution of the detection area is improved. Meanwhile, the location and identification accuracy of the detection target is improved.
Description
technical field [0001] The present invention relates to the technical field of sensors, in particular to infrared array sensor technology, and more specifically to a method and device for realizing adjustable resolution of the infrared array sensor. Background technique [0002] The infrared array sensor is a sensor formed by arranging multiple infrared sensors in the form of a pixel array on a substrate. The infrared array sensor can not only detect the static human body and the moving direction of the human body, but also measure the temperature distribution in the area, and then identify the overall shape or partial shape of the human body in the measurement area according to the difference between the human body temperature and the ambient temperature, and realize the overall outline of the human body. , and even the positioning and identification of each part of the human body. In the field of home appliance control, intelligent control can be realized based on the pos...
