1. A posture evaluating method, comprising:
capturing an image under test by using an image capturing apparatus;
identifying a plurality of key points in the image under test, wherein the key points correspond to a plurality of positions of a main body in the image under test and comprise a first key point group and a second key point group;
obtaining a position of the first key point group, and defining a first geometric relation via association of the first key point group;
determining a relative position between the main body and the image capturing apparatus according to the first geometric relation, wherein each of the relative position has a corresponding default geometric relation; and
comparing the default geometric relation and a second geometric relation formed by association of the second key point group to generate a comparison result, wherein: the relative position comprises a front side, an oblique profile, and a profile; and comparing the default geometric relation corresponding to each of the relative position and the second geometric relation formed by association of the second key point group comprises:
correspondingly defining the second geometric relation according to a type of the relative position, wherein the second geometric relation comprise positions of two key points in the second key point group, at least one connection line formed by positions of any two key points in the second key point group, a ratio of two of the connection lines, or an angle, a ratio or a geometric relation between the at least one connection line and a third line, and the third line is a reference line extending from one key point in the second key point group; and
determining whether the second geometric relation satisfies the default geometric relation.
