[0063] Embodiment one

[0065] S1, receiving a first image of a subject taken by a front camera 1, the first image being a front view of the subject's bilateral upper limbs in a standing body forward bending posture; receiving a second image of the subject taken by a bottom camera 2, the second image being a top view of the subject's bilateral upper limbs in a standing body forward bending posture; preferably, the subject is measured not only in the relaxed state of the upper limbs, but also in the standing body forward bending posture, and the bilateral hands are measured by grabbing an equal weight object.

[0066] Preferably, to avoid the introduction of additional deviation caused by the incorrect standing position of the subject, the standing position of the feet needs to be corrected. The image of the feet of the subject standing on the bottom scanner is received by the bottom scanner, the symmetry of the arches of the feet is analyzed according to the image of the feet, and the possibility of the abnormality of the spine is judged according to the symmetry of the arches of the feet. For the case of imbalance of the arches of the feet, the abnormality of the spine needs to be focused on. And the subject is required to keep the sides of the feet and the heels close to the fixed bars, the arms are naturally drooping, the hands are clenched, the dumbbells are held tightly, and the fists are opposite to each other.

[0067] In this embodiment, the shooting direction of the front camera 1 is horizontal, the shooting direction of the bottom camera 2 is vertically upward, and the shooting ranges of the two cameras intersect; wherein the bottom camera 2 is a backlit camera, which can reduce the influence of light or sunlight during shooting.

[0068] S2, according to the first image shot by the front camera 1, the first deviation degree information of the bilateral upper limbs in the coronal plane is obtained; according to the second image shot by the bottom camera 2, the second deviation degree information of the bilateral upper limbs in the horizontal plane is obtained;

[0069] In step S2, the first deviation degree information of the bilateral upper limbs in the coronal plane is obtained according to the first image, which is specifically: posture estimation or gesture estimation is performed on the first image, and the first wrist position of the subject is estimated; the first inclination angle of the wrists is calculated according to the connecting line of the first wrist position and the coronal axis, and the first deviation degree of the upper limbs is obtained through the first inclination angle;

[0070] According to the second image, the second deviation degree information of the bilateral upper limbs in the horizontal plane is obtained, which is specifically: posture estimation or gesture estimation is performed on the second image, and the second wrist position of the subject is estimated; target detection is performed according to the second wrist position, and the detected second wrist image is extracted through image segmentation; the second inclination angle of the wrists is calculated according to the connecting line of the second wrist image and the horizontal axis, and the second deviation degree of the upper limbs is obtained through the second inclination angle.

[0071] In which, the deviation degree information includes the positions of the fists, the palms, the wrists, the same joint positions of the hands, the elbow joint positions, the shoulder joint positions, also includes the positions of the objects grasped by the hands, and also includes the positions of the bilateral upper limbs when the subject grasps the heavy objects in the standing forward bending posture.

[0072] S3, according to the collected deviation degree information, the severity of the scoliosis and the rotation of the spine is analyzed.

[0073] That is, according to the deviation degree information of the bilateral upper limbs, the positions of the bilateral upper limbs are obtained, the deviation angle of the line connecting the positions of the bilateral upper limbs is calculated by referring to the coronal axis, and whether the deviation angle reaches an angle threshold is calculated according to the deviation angle obtained in the first image and the deviation angle obtained in the second image.

[0074] Wherein, according to the collected deviation degree information, the severity of scoliosis and spinal rotation is analyzed, including: if the first inclination angle is greater than the first threshold or the second inclination angle is greater than the second threshold, it is determined that the subject has scoliosis or spinal rotation, otherwise, it is determined that the subject has normal spine.

[0075] Specifically, for the video frame images obtained by the two orientation cameras, a pose estimation algorithm or a gesture estimation algorithm of artificial intelligence computer vision is applied respectively, for example, a pose estimation or gesture estimation algorithm of OpenPose, AlphaPose or Mediapipe is used to obtain the positions of the wrists of the two hands (or the positions of the index joints of the two hands), and the inclination angle of the line connecting the positions of the wrists of the two hands is automatically calculated, which represents the deviation degree of the bilateral upper limbs, and the severity of scoliosis and spinal rotation is further analyzed. For example, if the angle of the line connecting the index joints of the two hands in the front image exceeds the threshold of 20°, or the deviation degree of the angle of the line connecting the index joints of the two hands in the image taken from below exceeds the threshold of 20°, it is considered that a suspicious case is found, and X-ray or CT is needed for further diagnosis.
