This invention discloses a full-body live-streaming call imaging system and method for smart glasses based on real-time correction using multiple sensors, belonging to the field of smart wearable devices and real-time audio and video communication technology. This invention integrates multiple types of sensing sensors distributed across smart glasses to collect real-time data on user facial details, clothing features, limb posture, gait, and surrounding environmental space. It then constructs a complete 3D human body model from head to toe using lightweight AI algorithms. Simultaneously, a real-time human body data correction mechanism is added, dynamically calibrating human body recognition data at the millisecond level through frame comparison, iterative compensation, and anomaly filtering, solving industry challenges of model distortion and contour offset in dynamic scenes. Combined with SLAM 3D environment reconstruction technology and an adaptive lens distance adjustment algorithm, this invention can intelligently switch between facial close-ups and full-body dual imaging modes, with no limb cropping, no image distortion, and no image jitter throughout the process, realistically reproducing the user's full-body movements and surrounding environment. This invention effectively solves the technical pain points of traditional smart glasses, such as limited imaging in video calls and live streaming, poor dynamic adaptability, and low recognition accuracy. It significantly improves imaging stability, integrity, and intelligence, and is suitable for various scenarios such as remote physical education, immersive live streaming, and virtual meetings. It has extremely high practical value and promising prospects for promotion.

The present invention relates to a fertilization method for increasing the potassium content of the middle and upper tobacco leaves of Yuxi flue-cured tobacco. Large particles are used as base fertilizer, and the amount of potassium applied is determined according to the chloride ion content of the soil, and the last topdressing is applied 10 days later than the conventional topdressing time. Wherein (1) for fields with a soil chloride ion content of <40 mg / kg, the potassium application amount is applied according to the local recommended amount of potassium; (2) for fields with a soil chloride ion content of 40 to 80 mg / kg, the potassium application amount is increased by 15% on the basis of the local recommended amount of potassium; (3) for fields with a soil chloride ion content of 80.1 to 90 mg / kg, the potassium application amount is increased by 20% on the basis of the local recommended amount of potassium. The method of the present invention can increase the potassium content and potassium-chloride ratio of tobacco leaves, make the chemical composition of tobacco leaves more coordinated, and thus improve the quality of tobacco leaves.
