Embodiment Construction
[0039] The present invention will be further described below in conjunction with specific examples and accompanying drawings.
[0040] figure 1 It is a schematic diagram of the hardware structure of an embodiment of the present invention. Based on the positioning principle of stereo vision, a student's healthy learning posture reminder system is designed by using two infrared cameras 1 combined with a learning table 3. The system hardware is composed of an infrared camera 1, an identification mark 6, a computer and the like. The infrared camera 1 is connected with the computer 5 through bluetooth (or data cable). Two infrared light sources are respectively installed on the outer edges of the two cameras to form an infrared camera 1, the camera is fixed on the camera bracket 2, and the camera bracket 2 is placed in a suitable position on the study table 3 to ensure that the student 4 is in the field of view of the camera, and the student sits on the chair 7 Above, the identif...

The invention discloses a reminding system for health study posture for student, and the reminding system comprises a data acquisition module used for collecting the position of the camera and student identification mark; a distance calculating module used for calculating the distance between the head and the shoulders; a data setting module used for setting the preset value of the corresponding distance between the head and the shoulders under ideal position of different heights and gender, and the coordinate preset value of the camera and student identification mark; an angle calculating module used for calculating the head relative change angle; a posture judging module used for comparing the head relative change angle with the preset head relative change angle range and judging whether the posture is right; an alarming module used for outputting the alarm signal for the wrong posture. The stereo vision technology is used for reminding the health study posture for student, supervising the study posture for student at real time and reminding, so that the system can be widely used for the group of students.
Description
technical field [0001] The invention belongs to a posture reminder system for students, in particular to a posture reminder system and method for students' healthy learning.
