1. An assistive fitness system, comprising:
a thermal imaging device configured to receive an infrared signal from a human body of a user and perform thermal imaging processing based on the infrared signal to generate a human body image;
a processor configured to compare the human body image with a reference image of a standard fitness movement to generate a comparison result; and
a display device configured to display the human body image and the comparison result of the human body image and the reference image in a nested manner,
wherein the assistive fitness system further comprises:
a camera configured to obtain an image of the user; and
a distance sensor configured to acquire a first distance between the user and the display device, wherein:
the processor is further configured to determine, from the image of the user and the first distance, position coordinates of a target position at which the user is gazing in a preset coordinate system, the preset coordinate system being located in association with the human body; and
the display device is further configured to display the human body image and the comparison result in the nested manner at the target position,
wherein the camera is configured to obtain a first image of the user looking straight at the display device and a second image of the user gazing at a target position; and the processor is further configured to determine the position coordinates of the target position in the preset coordinate system based on the first image, the second image, and the first distance, and
wherein the processor is further configured to:
identify a first center of a left-eye pupil and a first center of a right-eye pupil in the first image;
identify a second center of the left-eye pupil or a second center of the right-eye pupil in the second image;
determine a position abscissa of the target position in the preset coordinate system based on a first angle, a second distance between the first center of the left-eye pupil and the first center of the right-eye pupil in a preset horizontal direction, and the first distance, wherein the first angle is a deflection angle between the first center of the left-eye pupil and the second center of the left-eye pupil in the preset horizontal direction, or, a deflection angle between the first center of the right-eye pupil and the second center of the right-eye pupil in the preset horizontal direction; and
determine a position ordinate of the target position in the preset coordinate system based on a second angle, the second distance and the first distance, wherein the second angle is a deflection angle between the first center of the left-eye pupil and the second center of the left-eye pupil in a preset vertical direction, or, a deflection angle between the first center of the right-eye pupil and the second center of the right-eye pupil in the preset vertical direction, wherein:
an origin of the preset coordinate system is a central position between the first center of the left-eye pupil and the first center of the right-eye pupil; and
the preset vertical direction is perpendicular to the preset horizontal direction.
