Description

technical field [0001] The invention relates to the technical field of body detection, in particular to a system and method for real-time detection and evaluation of human foot dynamics. Background technique [0002] At present, the force analysis tools for human feet during exercise mainly use insole-type pressure distribution or rectangular pressure distribution detection boards. The basic principles of these two devices use pressure distribution sensors to collect the contact surface pressure between the foot and the ground. , and then calculate the vertical force and other derived parameters in the ground reaction force. The disadvantages of these two devices are: [0003] 1. The insole-type pressure distribution is based on shoes. In actual testing, it often occurs that the pressure distribution and shoes cannot be optimally matched, which affects the accuracy of the test results; [0004] 2. The insole-like pressure distribution cannot detect the spatial domain parame...

AI Technical Summary

Problems solved by technology

[0003] 1. The insole-type pressure distribution is based on shoes. In actual testing, it often occurs that the pressure distribution and shoes cannot be optimally matched, which affects the accuracy of the test results;

[0004] 2. The insole-like pressure distribution cannot detect the spatial domain parameters of the gait during walking;

[0005] 3. Rectangular pressure distribution plate is limited by space, so long-distance detection cannot be achieved, thus affecting data accuracy;

[0006] 4. Both of them can only detect the vertical force, and cannot obtain three-dimensional space data such as the shear force and moment of the foot in the front, back, left and right directions;

[0007] 5. Neither of them can obtain the angle data when the foot is in contact with the ground;

[0008] 6. Due to the limitations of the above detection methods, it is impossible to form an effective evaluation method for human foot dynamic mechanics information;

[0009] 7. The spatial domain data in the gait cycle cannot be obtained, the best fitting relationship between the measurement element and the measurement position of the human foot cannot be formed, long-distance detection cannot be performed, and multi-source information on the dynamic mechanics (macro and micro) of the human foot cannot be obtained (ground Reaction force, torque, gait cycle data, pressure, area, angle, angular acceleration, linear acceleration and other information) and other shortcomings and problems
