1. A method for obtaining a safe interval of a human body parameter in a built environment, comprising the following operations:
obtaining a first facial image, a benchmark human body parameter, and a human body posture analysis result of a target user in a target built environment;
inputting the first facial image into an emotion analysis model to obtain an emotion analysis result; and
obtaining the safe interval of the human body parameter of the target user according to the emotion analysis result, the human body posture analysis result, and the benchmark human body parameter,
wherein before the operation of obtaining the first facial image, the benchmark human body parameter, and the human body posture analysis result of the target user in the target built environment, the method further comprises:
obtaining a plurality of posture images of the target user in the target built environment;
obtaining a plurality of key point coordinates corresponding to each of the posture images;
obtaining a first human body angle and a second human body angle corresponding to each of the posture images according to the plurality of key point coordinates of each of the posture images;
obtaining initial human body posture information corresponding to each of the posture images according to the first human body angle, the second human body angle and a preset angle threshold of each of the posture images; and
obtaining the human body posture analysis result according to the initial human body posture information.
