Human spine posture anomaly detection method and device, terminal and medium

The invention discloses a human body spine posture anomaly detection method and device, a terminal and a medium, and the method comprises the steps: carrying out the image segmentation and edge extraction processing of a human body posture detection image based on a shot human body posture detection image, and obtaining a human body feature image of a human body part; then determining a plurality of human body posture detection points used for detecting a human body spine according to the human body feature image, calculating human body posture feature parameters based on the human body posture detection points, and inputting the calculated human body posture feature parameters into a human body posture detection model obtained by training based on a preset human body posture feature parameter sample; and detecting the human body posture characteristic parameters of the detected object by using priori knowledge formed based on training of the human body posture detection model to obtain a human body posture d
