After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.

[0053] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0054] The embodiments of this application will now be described in further detail with reference to the accompanying drawings.

[0055] This application provides a posture guidance method for optical 3D human body measurement, and the main process of the method is described below.

[0056] like Figure 1 As shown:

[0057] Step S101: Obtain three-dimensional image information of the human body.

[0058] In this embodiment, the three-dimensional image information of the person being tested is obtained by scanning with a 3D camera. During the actual physical examination, the person being tested enters the measurement room, which is equipped with a 3D camera. By scanning the measurement space with the 3D camera, the 3D information images of the human body in frontal or multi-directional directions can be obtained in real time and quickly. Furthermore, the 3D camera can be used to track the position and state of the person in the measurement room. It is understood that there are various ways to obtain three-dimensional image information of the human body. In this embodiment, only the method of capturing images with a 3D camera is used to obtain three-dimensional image information of the human body. The method of obtaining the image information is not limited. The use of a 3D camera here is only an example. As long as the three-dimensional image information of the human body can be obtained, it is acceptable.

[0059] Step S102: Obtain human body posture information based on the three-dimensional human body image information.

[0060] Specifically, based on the three-dimensional human body image information, human body state information, joint coordinate information, and limb orientation information are obtained; based on the human body state information and joint coordinate information, limb flexion and straightness information and upper limb orientation information are obtained; based on the joint coordinate information and limb orientation information, human body orientation tendency information is obtained; based on the limb flexion and straightness information, upper limb orientation information, and human body orientation tendency information, human body posture information is obtained.

[0061] Understandably, the three-dimensional image information of the human body obtained through step S101 represents the real-time state of the human body, i.e., the state of the person being tested in the measurement room. The current state information, joint coordinate information, and limb orientation information of the person being tested can be extracted from this three-dimensional image information. The human state information includes standing and sitting postures, because when collecting body data in the measurement room, different body data needs to be presented in both standing and sitting postures. Therefore, when obtaining the three-dimensional image information, it is necessary to first determine whether the person being tested is currently standing or sitting. Then, it is necessary to determine the joint coordinate information and limb orientation information of the person being tested. The joint coordinate information refers to the coordinate information in three-dimensional space. The corresponding body data can be determined through the coordinate information, and the joint coordinates can also help determine whether the posture of the person being tested is standard. Similarly, limb orientation information also helps to determine the body data and verify the standard of the posture of the person being tested.

[0062] After obtaining the body position information and joint coordinate information, the limb flexion and extension information and upper limb orientation information can be determined based on these two. The limb flexion and extension information refers to whether the limbs are straight. When the limbs are bent, the collected body data is inaccurate. Moreover, the positions of the joints in the limbs are different in standing and sitting postures. The limb flexion and extension information and upper limb orientation information also help determine the body data of the subject and correct the subject's posture. Then, the body orientation tendency information is determined by the joint coordinate information and limb orientation information. The body orientation tendency information refers to whether the subject has a forward or backward posture. Finally, the limb flexion and extension information, upper limb orientation information, and body orientation tendency information are integrated to obtain the body posture information.

[0063] It is understood that in this embodiment of the application, the spatial coordinate information of the joint position can be obtained through the 3D camera. This spatial coordinate information represents the joint coordinates of the person being tested in the current state. Therefore, based on the human body state of the person being tested, the limb flexion and straightness information, upper limb orientation information, and human body orientation information can be obtained by analyzing and calculating the joint coordinate information. The limb flexion and straightness information, upper limb orientation information, and human body orientation information obtained here are all corresponding information in the current state of the person being tested.

[0064] It should be noted that in the embodiments of this application, the joint coordinate information includes joint name information and coordinate information, such as ankle joint (x,y,z); after obtaining the joint coordinate information based on the three-dimensional image information of the human body, since the joint coordinate information is the basis for subsequent calculations, the joint coordinate information needs to be corrected.

[0065] Specifically, historical joint information is retrieved, and real-time joint association information is obtained based on human body status information and historical joint information; joint correction information is obtained based on real-time joint association information and joint coordinate information; and joint coordinate information is corrected based on joint correction information.

[0066] The historical joint information here includes historical human body state information and historical joint group information corresponding to the historical human body state information; the historical joint group information includes multiple historical joint coordinate information and joint association information; the historical joint coordinate information includes historical joint name information and historical coordinate information; the historical human body state information here also includes standing posture and sitting posture; the historical joint group information is used to characterize the related joint information in the standing or sitting posture; the joint association information here indicates the correlation between joints; for example, in the standing posture, the z-coordinates of the elbow joint and the wrist joint are the same or similar, where similar means that the difference between their z-coordinates is within a preset range; it can be understood that when the human body is in a standing posture, the arm hangs naturally, so the wrist and elbow can be approximated as a straight line, so their z-coordinates should be the same or similar, and this relationship is the joint association information of the elbow joint and wrist joint in the standing posture.

[0067] After determining the current state of the human body, real-time joint association information matching the current state can be found from historical joint information. Then, joint correction information is determined based on the real-time joint association information and joint coordinate information. The joint coordinate information is corrected using the real-time joint association information to find the joint groups with correlation in the current state. The joint coordinate information within the joint groups is then analyzed to finally determine the joint correction information. Finally, the joint coordinate information is corrected using the joint correction information. Through the above method, error correction and adjustment of joint coordinate information can be achieved, ensuring the accuracy of joint coordinate information obtained from the three-dimensional human body image information, thereby improving the accuracy of subsequent calculations.

[0068] Step S103: Determine posture adjustment information based on the human body posture information and preset standard posture rules.

[0069] Specifically, the process involves: obtaining posture data based on human body posture information; retrieving preset benchmark data; determining posture adjustment information based on the posture data, preset benchmark data, and preset standard posture rules; obtaining real-time posture image information and posture type information based on the posture data; obtaining standard posture image information based on the posture type information and preset posture image information; obtaining image adjustment information based on the real-time posture image information, standard posture image information, and preset standard posture rules; obtaining text adjustment information based on the posture data and preset benchmark data; and obtaining overall posture adjustment information based on the image adjustment information and text adjustment information.

[0070] Step S104: Adjust the posture of the person being tested according to the posture adjustment information.

[0071] After obtaining the posture adjustment information, the posture of the test subject can be adjusted according to the posture adjustment information; the posture of the test subject after adjustment is judged. If the posture meets the standard, the body data of the test subject after adjustment is obtained, and the measurement result is obtained according to the body data and the preset standard body data.

[0072] The above methods can be used to adjust the posture of the person being tested, thereby improving the efficiency and accuracy of collecting the person's body data.
