Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of motion sensing, in particular to a motion sensing trousers and a motion sensing system. BACKGROUND

[0002] Motion capture refers to a technology of recording and processing actions of people or other objects by using optical, inertial and other methods. With the development of virtual reality, human-computer interaction, network communication and other technologies, the application range of motion capture technology is also more and more extensive, and the market demand of motion capture equipment is also increasing year by year.

[0003] The existing mainstream space positioning and motion capture technology includes two categories: optical positioning and motion capture (including infrared positioning, laser positioning, etc.) and inertial motion capture. Compared with these two technologies, the optical positioning and motion capture technology involves infrared positioning technology or laser positioning technology, both of which have problems of high cost, great influence by environment, easy to be blocked, etc.; the inertial motion capture technology is not easy to be disturbed by external environment, but the precision is lower than that of optical positioning, and the measurement error is easy to accumulate.

[0004] More specifically, the principle of infrared positioning technology is to install infrared cameras at different positions, the cameras emit infrared light, and the positioning space is covered and shot; the objects to be positioned in the space are marked with important nodes using infrared reflective material, reflect the infrared light emitted by the infrared camera, and are captured by the infrared camera; then the position and relative position change of each marked important node in the three-dimensional space are calculated through image processing algorithm. The advantages of infrared positioning technology are high precision and low delay; the disadvantages are complex device construction, high cost of site and labor, and the marked points are easy to be blocked, resulting in loss of positioning.

[0005] The principle of laser positioning technology is to emit vertical and horizontal laser beams by a pair of laser positioning base stations to scan the space; a plurality of laser position trackers are installed on the objects to be positioned in the space, the three-dimensional coordinates of the objects are obtained by calculating the angle difference of the laser beams projected on the objects; the spatial position and motion trajectory of the objects can be calculated by combining the measurement results of the plurality of laser position trackers. The advantages of laser positioning technology are low cost, high precision and strong real-time without complex data operation; the disadvantage is that the positioning is lost due to blocking.

[0006] The principle of inertial motion capture technology is to measure the motion parameters of the sensor by using an inertial measurement unit (IMU) composed of a three-axis gyroscope, a three-axis accelerometer and a three-axis magnetometer. The advantages of inertial motion capture technology are low requirement for motion capture environment, good continuous capture stability and convenient operation; the disadvantage is that the precision is lower than that of optical positioning technology, and the error is easy to accumulate.

[0007] Therefore, when performing motion capture on a human leg, there is a problem of being unable to balance high cost performance, low environmental requirements, high stability, and high precision by the above-mentioned manner. SUMMARY

For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0076] Please refer to Figures 1 to 4 The motion sensing trousers provided in the embodiments of the present application include a trousers body 10 and a distributed strain sensor 20. The trousers body 10 has elasticity and is in the form of tights, and can fit the legs of a wearer.

[0077] The distributed strain sensor 20 includes a stretchable conductor unit 21. The stretchable conductor unit 21 includes a plurality of concentrated sensing regions 211. The concentrated sensing regions 211 have flexibility, so that the concentrated sensing regions 211 can follow the deformation of the trousers body 10 to produce changes in electrical properties.

[0078] The plurality of concentrated sensing areas 211 are arranged at least in all or part of the following areas on the pants body 10: an area on the pants body 10 corresponding to the lower side of the waist of the human body, an area on the pants body 10 corresponding to the root of the outer side of the thigh of the human body, an area on the pants body 10 corresponding to the lower side of the outer side of the thigh of the human body, an area on the pants body 10 corresponding to the side of the knee of the human body, and an area on the pants body 10 corresponding to the back side of the lower leg of the human body;

[0079] The concentrated sensing area 211 arranged at the area on the pants body 10 corresponding to the lower side of the waist of the human body can be used to detect the movement of the waist and ankle joint of the wearer; the concentrated sensing area 211 arranged at the area on the pants body 10 corresponding to the root of the outer side of the thigh of the human body can be used to detect the movement of the ankle joint of the wearer, such as lifting the leg; the concentrated sensing area 211 arranged at the area on the pants body 10 corresponding to the lower side of the outer side of the thigh of the human body can further comprehensively detect the movement of the ankle joint of the wearer; the concentrated sensing area 211 arranged at the area on the pants body 10 corresponding to the side of the knee of the human body can detect the movement of the knee joint of the wearer; and the concentrated sensing area 211 arranged at the area on the pants body 10 corresponding to the back side of the lower leg of the human body can detect the position of the lower leg and the movement of the ankle joint of the wearer. In the above areas, one or more concentrated sensing areas 211 can be arranged, and the sensing sensitive direction of each concentrated sensing area 211 can be the same or different, which is not limited.

[0080] Specifically, when the pants body 10 is pulled due to the movement of the wearer, the stretchable conductor unit 21 will deform following the pulling of the pants body 10, thereby changing the electrical performance; after the external data box connects the stretchable conductor unit 21 and measures the electrical performance parameters, the stretching deformation of the pants body 10 can be known according to the change of the electrical performance parameters, thereby mapping the movement of the wearer.

[0081] In this embodiment, the plurality of concentrated sensing areas 211 can include a first sensing area q1, a second sensing area q2, a third sensing area q3, a fourth sensing area q4, and a fifth sensing area q5; the first sensing area q1, the second sensing area q2, the third sensing area q3, the fourth sensing area q4, and the fifth sensing area q5 are arranged on the pants body 10 corresponding to the positions of the lower side of the waist, the root of the outer side of the thigh, the lower part of the outer side of the thigh, the side of the knee, and the back side of the lower leg of the human body.

[0082] Specifically, after the wearer wears the pants body 10, the first sensing area q1 is located below the waist side of the wearer, mainly for detecting the movement of the waist and hip joint of the wearer; the second sensing area q2 is located at the root of the outer thigh, mainly for detecting the movement of the hip joint (leg lifting) of the wearer; the third sensing area q3 is located below the outer thigh, also for detecting the movement of the hip joint of the wearer; the fourth sensing area q4 is located in front of the knee joint of the wearer, for detecting the movement of the knee joint of the wearer; the fifth sensing area q5 is located at the back of the lower leg (calf) of the wearer, for detecting the movement of the ankle joint of the wearer. Through the arrangement of multiple concentrated sensing areas 211, the movement of the whole leg of the wearer can be mapped, which can have the characteristics of high precision, low cost and not easy to be disturbed by the outside world compared with optical positioning and motion capture technology and inertial motion capture technology.

[0083] In one embodiment, the plurality of garment panels of the pants body 10 includes a first panel 11; the first panel 11 is a whole piece, and covers all or part of the area corresponding to the lower side of the waist of the human body, the root of the outer thigh of the human body, the lower side of the outer thigh, the side of the knee, and the back of the lower leg on the pants body 10; each concentrated sensing area 211 is arranged on the first panel 11. Among them, the first panel 11 can include two, and are respectively located at positions corresponding to two legs of the pants body 10.

[0084] In this scheme, the electrical performance parameter can refer to the capacitance value or the resistance value; in this embodiment, the electrical performance parameter is taken as the resistance value as an example for description. Specifically, the stretchable conductor unit 21 is made of a stretchable conductor material, including but not limited to a stretchable conductive silver paste material, a stretchable carbon nanomaterial, a stretchable conductive polymer material, and a liquid metal material, etc.

[0085] Because the stretchable conductor material adopted by the distributed strain sensor 20 is easy to be damaged when subjected to concentrated stress, if the conventional panel design in the prior art is adopted, the distributed strain sensor 20 needs to be covered on multiple panels at the same time, which will bring the following problems:

[0086] (1) There are downward concave joint parts or upward convex seam parts between different panels, which causes the stretchable conductor unit at the above position to be easy to be damaged due to concentrated shear stress;

[0087] (2) When part of the distributed strain sensor 20 is pressed and fixed to the panel, it needs to be pressed and fixed on multiple panels at the same time, which increases the processing difficulty, and the position of the distributed strain sensor 20 is easy to deviate due to the problem of difficult alignment, which reduces the processing precision;

[0088] (3) In the process of fixing the distributed strain sensor 20 on the multiple pieces of the cutting piece, it is easy to preload a certain tension to the distributed strain sensor, which causes the sensor to have a certain deformation after the fixing is completed, thus affecting the detection accuracy of the sensor.

[0089] The motion sensing trousers in the scheme can make the distributed strain sensor 20 cover on the single piece of the first cutting piece 11 through the whole first cutting piece 11, so as to avoid the occurrence of the above problems on the premise of realizing the functions of motion capture and dimension detection.

[0090] In another embodiment, the first cutting piece 11 also covers the region corresponding to the human buttocks on the trousers 10. Correspondingly, the distributed strain sensor 20 can extend to the buttocks region, so as to be able to measure the motion dimension of the wearer's buttocks and assist in measuring the motion of the wearer's hip joint.

[0091] In an embodiment, the stretchable conductor unit 21 further includes a plurality of conductor lines 212; one end of the plurality of conductor lines 212 is connected to the concentrated sensing area 211, and the other end is used to connect a data box. The data box refers to a component for collecting the electrical performance parameters of the stretchable conductor unit 21, so that the change of the electrical performance parameters of the stretchable conductor unit 21 can be known through the data box.

[0092] The distributed strain sensor 20 adopted in the scheme has excellent stretchable and bendable performance. In a more specific embodiment, please refer to Figure 4 , the distributed strain sensor 20 can further include a stretchable base layer 22 and a stretchable packaging layer 23; the stretchable base layer 22 is laid on the first cutting piece 11; the stretchable conductor unit 21 is laid on the stretchable base layer 22; and the stretchable packaging layer 23 is laid on the stretchable base layer 22 and covers the stretchable conductor unit 21.

[0093] Specifically, the stretchable conductor unit 21 is connected to the first cutting piece 11 through the stretchable base layer 22, which can avoid the problem of easy damage due to the uneven fabric lines on the first cutting piece 11 caused by direct contact with the first cutting piece 11. In application, the stretchable base layer 22 can also be connected to the first cutting piece 11 through a glue layer, which plays a role of adhesion and protection, further avoiding damage to the stretchable base layer 22 and the stretchable conductor unit 21. The stretchable packaging layer 23 covers the stretchable conductor unit 21, which plays a role of waterproofing, fixing and protection for the stretchable conductor unit 21. It should be noted that in order to further improve the waterproof effect of the distributed strain sensor 20, the stretchable packaging layer 23 can also cover a protective layer. The protective layer can be made of honeycomb-shaped elastomers made of rubber, silicone and the like, which further improves the protection of the stretchable conductor unit 21.

[0094] Further, please refer toFigure 4 The pants body 10 can further comprise a bottom layer 17, and the first cutting piece 11 is arranged on the bottom layer 17. That is, the bottom layer 17 is arranged on the inner side of the first cutting piece 11, and the distributed strain sensor 20 is arranged on the outer side of the first cutting piece 11. The inner side refers to the side of the first cutting piece 11 close to the human body. In order to solve the problem of perspiration after exercise of the wearer, in the embodiment, by arranging the first cutting piece 11 on the bottom layer 17, the possibility of direct contact of water to the distributed strain sensor 20 can be reduced. The bottom layer 17 can be an elastic waterproof cloth with good waterproof performance and small elastic modulus.

[0095] Meanwhile, the bottom layer 17 is provided with an opening at a position corresponding to the front side of the knee, so as to be able to protect the sensor at the knee while avoiding increasing the elastic modulus of the position directly opposite to the knee, and to facilitate the wearer to make a bending leg action and improve the comfort.

[0096] Further, the plurality of cutting pieces further comprise a second cutting piece 12, the second cutting piece 12 covers an area corresponding to the inner side of the thigh and the rear side of the knee of the human body, and is connected with the first cutting piece 11.

[0097] By arranging the second cutting piece 12, the comfort of the whole motion sensing pants can be improved. Specifically, the inner side of the thigh and the rear side of the knee covered by the second cutting piece 12 are less stretched and deformed during the movement of the wearer, and therefore the distributed strain sensor 20 can not be covered. Meanwhile, by arranging the second cutting piece 12 instead of directly covering the inner side of the leg and the rear side of the knee by the first cutting piece 11, on the one hand, the cutting of the first cutting piece 11 is facilitated, and on the other hand, the first cutting piece 11 is more likely to be deformed, and the sensitivity to motion sensing can be improved.

[0098] Specifically, the conventional yoga pants or leggings are prone to accumulate cloth under the knee and generate wrinkles after being worn by the wearer. By arranging the second cutting piece 12, the first cutting piece 11 can be bent around the position corresponding to the rear side of the knee, and the bending part can not only extend to the rear side of the calf, but also avoid the accumulation of cloth under the knee, so as to avoid the sensitivity of the distributed strain sensor 20 being reduced due to the influence of the cloth accumulation under the knee.

[0099] Further, the plurality of cutting pieces further comprise a third cutting piece 13, the third cutting piece 13 covers an area corresponding to the front side of the calf of the human body, and is connected with the first cutting piece 11 through the zipper strip 15.

[0100] The first piece 11 can be laid flat. The third piece 13 is used to connect with the first piece 11 to form the pant legs. Specifically, since the inner pant body made of the first piece 11 is a tight pant for better fitting the wearer's legs so that the distributed strain sensor 20 can more accurately capture the wearer's movements and leg body dimensions, the wearer can have difficulty wearing the inner pant body when wearing the inner pant body due to the tightness of the pant, and since the distributed strain sensor 20 is covered on the first piece 11, the elastic modulus of the first piece 11 is increased, thus further amplifying the problem. Therefore, the third piece 13 is provided, which not only facilitates overall processing, but also reduces the difficulty of putting on and taking off the inner pant body through the provision of the zipper strip 15, thereby improving the wearer's experience.

[0101] In one embodiment, referring to Figure 1 , the motion sensing pant further comprises a fourth piece 14. The fourth piece 14 can be provided at a position corresponding to the human crotch and connected with the first piece 11.

[0102] In addition, an elastic waistband 16 can also be included. The waistband 16, the first piece 11, the second piece 12, the third piece 13, and the fourth piece 14 together form the inner pant body.

[0103] In one embodiment, referring to Figure 1 , Figure 6 and Figure 9 , the distributed strain sensor 20 further comprises an interface area 213. The interface area 213 is provided on the pant body 10 and is used for detachable connection with the data box 30. The concentrated sensing area 211 is connected to the interface area 213 through the conductor line 212. The interface area 213 is provided with a port connected to the conductor line 212, and the data box 30 is electrically connected to the conductor line 212 through the port to collect signals of each conductor line 212.

[0104] Specifically, the plurality of concentrated sensing areas 211 are respectively connected to one end of the plurality of conductor lines 212; the other end of the plurality of conductor lines 212 is connected to the interface area 213 and connected to an external data acquisition device by the interface area 213.

[0105] Specifically, the interface area 213 can be provided on the pant body 10 at a position corresponding to the outside of the human thigh. That is, when the wearer wears the motion capture pant, the data box 30 will be located on the outside of the wearer's thigh close to the leg surface, which facilitates the wearer to disassemble and assemble the data box 30, and at the same time can as little as possible affect the wearer's movement (avoiding touching the data box 30).

[0106] In another embodiment, an outer short pants can also be included; the outer short pants can be worn by the wearer after wearing the inner pants body, and can be sleeved outside the inner pants body to shield the tight area of the waist to the leg of the wearer after wearing the inner pants body, and can also protect the distributed strain sensors 20 and the data box 30 of the thigh part.

[0107] Further, the concentrated sensing area 211 is arranged in a meander circuit or interdigital circuit by patterning the conductive wire. When the concentrated sensing area 211 is arranged in a meander circuit, the electrical performance parameter generated by the deformation of the concentrated sensing area 211 is resistance. When the concentrated sensing area 211 is arranged in an interdigital circuit, that is, the concentrated sensing area 211 forms a plurality of interdigital capacitors by patterning the conductive wire, correspondingly, the electrical performance parameter generated by the deformation of the concentrated sensing area 211 is capacitance.

[0108] In one embodiment, the concentrated sensing area 211 can be used as the main sensing area; in order to reduce the influence of the change of the electrical performance parameter of the conductive wire 212 after deformation, a thin-diameter conductive wire can be selected for the concentrated sensing area 211, and a thick-diameter conductive wire with a larger diameter than the thin-diameter conductive wire can be selected for the conductive wire 212, so that the elastic modulus of the conductive wire 212 is larger and the change of the electrical performance parameter after deformation is smaller, the influence of the conductive wire 212 on the concentrated sensing area 211 is reduced, and the detection accuracy of the concentrated sensing area 211 is improved.

[0109] In another embodiment, the wire diameter of the concentrated sensing area 211 is consistent with the wire diameter of the conductive wire 212, and both use thin-diameter conductive wires. In this embodiment, not only the concentrated sensing area 211 can detect the deformation of the pants body 10, but also the concentrated sensing area 211 and the conductive wire 212 are flexible so that the concentrated sensing area 211 and the conductive wire 212 can both change the electrical performance following the deformation of the pants body 60, that is, the position where the conductive wire 212 is arranged can also detect the deformation of the pants body 10. In addition, each concentrated sensing area 211 and each conductive wire 212 are not unique in the detection object. Since a single action of the wearer can cause deformation of multiple concentrated sensing areas 211, in addition to detecting the position where it is arranged, there can also be a situation where multiple concentrated sensing areas 211 and multiple conductive wires 212 are stretched together due to the stretching of the pants body 10, so that the concentrated sensing areas 211 and the conductive wires 212 around the detection part can be used to assist in measuring the motion of the detection part, and the detection accuracy is improved.

[0110] For example, in addition to causing the fourth sensing area q4 to deform, the knee bending action also causes the third sensing area q3 and the fifth sensing area q5 to deform enough to be detected, so that the knee bending action of the wearer can be more accurately detected through the signals of the third sensing area q3, the fifth sensing area q5 and the fourth sensing area q4 at the same time.

[0111] In one embodiment, please refer to Figure 1 、 Figures 5 to 8 All or part of the concentrated sensing area 211 includes a first loop 211a and a second loop 211b; the extension directions of the first loop 211a and the second loop 211b intersect; wherein the extension direction of the loop refers to the direction in which the loop is more sensitive in terms of sensing performance. Both ends of the first loop 211a and the second loop 211b are connected with a conductor line 212. The loop extension mode has a more sensitive strain detection capability. The loop extension direction of the first loop 211a can be the horizontal direction of the transverse direction; the loop extension direction of the second loop 211b can be the vertical direction of the longitudinal direction. By providing the first loop 211a and the second loop 211b with perpendicular extension directions in one concentrated sensing area 211, the concentrated sensing area 211 can have high sensing sensitivity in the extension direction of both loops, thereby improving the detection accuracy.

[0112] In application, the deformation of the first loop 211a and the second loop 211b can be judged by measuring the resistance values of the first loop 211a and the second loop 211b respectively.

[0113] In another embodiment, one end of the first loop 211a and the second loop 211b is electrically connected to each other; the conductor lines 212 connected by the first loop 211a and the second loop 211b are arranged side by side, and at least one conductor line 212 connected by the first loop 211a and at least one conductor line 212 connected by the second loop 211b are short-circuited.

[0114] In this embodiment, the first sensing area q1 and the third sensing area q3 located at the corresponding waist position are provided in the form of including the first loop 211a and the second loop 211b, and the other concentrated sensing areas 211 can each be provided with only a unidirectional extension loop.

[0115] And at least one conductor line 212 is connected to both ends of each loop, so that the total resistance of the loop and the two conductor lines 212 can be obtained by measuring the two conductor lines 212. In addition, a conductor line 212 is separately provided in the loop as an auxiliary conductor line, and the auxiliary conductor line is only short-circuited to one of the two conductor lines 212 connected to both ends of the loop, so that the resistance of the conductor line 212 itself can be obtained through the short-circuited conductor line 212, and the resistance of the loop itself can be calculated. Therefore, at least three conductor lines 212 are connected to each loop.

[0116] In the conductor line 212 connected with the concentrated inductive area 211 of the first loop 211a and the second loop 211b, in order to detect the electrical performance parameter of the first loop 211a and the second loop 211b without interfering with each other, please refer to Figure 5 , the conductor line 212 can be provided with the first line a1, the second line a2, the third line a3 and the fourth line a4 arranged side by side; the first end of the first loop 211a is connected to the interface area 213 through the first line a1, and the second end is connected to the first end of the second loop 211b; the second end of the second loop 211b is connected to the interface area 213 through the fourth line a4; the second end of the first loop 211a and the first end of the second loop 211b are both connected to the interface area 213 through the second line a2; the third line a3 is short-circuited with the second line a2.

[0117] Specifically, the first line a1, the second line a2, the third line a3 and the fourth line a4 are both connected to the same concentrated inductive area 211 at one end and converge to the interface area 213 at the other end, so the resistance in the initial state when the line does not deform can be considered consistent; when the wearer wears the motion sensing pants and moves, the deformation amplitude of each line can also be considered consistent, so the resistance of the above-mentioned line can still be considered consistent.

[0118] Therefore, when connecting the port of the first line a1 and the port of the second line a2, the total resistance R1 of the first loop 211a, the first line a1 and the second line a2 can be obtained, that is, R1=R a1 +R a2 +R 211a ;

[0119] When connecting the port of the third line a3 and the port of the fourth line a4, the total resistance R2 of the second loop 211b, the third line a3 and the fourth line a4 can be obtained, that is, R2=R a3 +R a4 +R 211b ;

[0120] When connecting the second line a2 and the third line a3, the total resistance R 23 =R a2 +R a3 of the second line a2 and the third line a3 can be obtained. Since R a1 =R a2 =R a3 =R a4 ; therefore, after R 23 is obtained, the values of R1 and R2 can be solved. Thus, the resistance change of the first loop 211a and the second loop 211b can be known, so that the action made by the wearer can be accurately mapped.

[0121] It is to be noted that the total resistance R 23 The loop formed by the second line a2 and the third line a3 not only serves to avoid the influence of the line resistance and only obtain the resistance of the loop circuit in the concentrated sensing area 211, but also serves as a sensor to detect the wearer's action or body circumference. For example, the second line a2 and the third line a3 of the first sensing area q1 extend from the side of the wearer's waist to the outside of the thigh and then to the interface area, so that R 23 The value of R 23 can still be used to detect the wearer's action. Therefore, the flexible sensor in the embodiment is not limited to the detection area in the concentrated sensing area 211, but can realize distributed strain detection. In addition, in the embodiment, the second line a2 and the third line a3 serve as the common lines of the first loop 211a and the second loop 211b, which can reduce the number of conductor lines 212, save the occupied width of the interface area 213, and does not affect the measurement of the resistance values of the loops.

[0122] Meanwhile, referring to Figure 6 , in order to further reduce the occupied width of the interface area 213, the ports of the conductor lines 212 in the interface area 213 can be staggered front and back.

[0123] In another embodiment, referring to Figure 8 , the plurality of concentrated sensing areas 211 further include a sixth sensing area q6, and the fifth sensing area q5 and the sixth sensing area q6 are arranged on the left and right sides of the corresponding back sides of the lower legs of the human body.

[0124] By arranging the fifth sensing area q5 and the sixth sensing area q6 on the left and right sides of the corresponding back sides of the lower legs of the human body on the pants body 10, the deformation of the pants body 10 corresponding to the lower leg position of the wearer during movement can be more comprehensively detected.

[0125] In a further improved embodiment, the conductor line 212 connected to the fifth sensing area q5 or the conductor line 212 connected to the sixth sensing area q6 crosses between the fifth sensing area q5 and the sixth sensing area q6, so that the conductor line 212 forms a body circumference sensing segment a67 crossing the left and right sides of the back of the lower leg of the human body. The body circumference sensing segment a67 is used to sense the body circumference change of the wearer.

[0126] Specifically, after the user puts on the pants 10, it causes deformation of the fifth sensing area q5 and the sixth sensing area q6, as well as the conductor circuit 212 connected to them, resulting in changes in electrical performance parameters. By detecting these changes in electrical performance parameters, the overall deformation of the first piece 11 located at the positions of the fifth sensing area q5 and the sixth sensing area q6 can be simulated and calculated, thereby calculating the change in the wearer's circumference at the calf area.

[0127] In one embodiment provided in this application, the body circumference sensing segment a67 maps the wearer's body circumference changes by the resistance change. That is, the change in the user's body circumference after wearing the garment will cause the resistance of the body circumference sensing segment a67 to change, thereby mapping the wearer's body circumference changes.

[0128] In this embodiment, the fifth sensing area q5 is located near the interface area 213, and correspondingly, the sixth sensing area q6 is located on the side farther away from the interface area 213 than the fifth sensing area q5. By obtaining the resistance difference between the body circumference sensing segment a67 after the wearer wears the sports sensing pants and the resistance difference between the target line segment a67 in the initial state, the wearer's calf circumference can be calculated based on this difference.

[0129] In a more specific embodiment, conductor line 212 further includes a fifth line a5, a sixth line a6, a seventh line a7, and an eighth line a8. The fifth line a5 and the sixth line a6 are connected to the fifth sensing area q5; the seventh line a7 and the eighth line a8 are connected to the seventh sensing area q7.

[0130] The fifth line a5 and the sixth line a6 are arranged in parallel side by side; the seventh line a7 and the eighth line a8 are arranged in parallel side by side. The resistance changes of the parallel lines during the deformation process can be considered to be the same. Part of the seventh line a7 and the eighth line a8 are arranged in parallel side by side with the fifth line a5 and the sixth line a6, and the other part spans between the fifth sensing area q5 and the sixth sensing area q6 to form the body circumference sensing section a67.

[0131] The length difference between the loop formed by the seventh line a7 and the eighth line a8 and the loop formed by the fifth line a5 and the sixth line a6 can be approximated as the length of the body circumference sensing segment a67. Therefore, by obtaining the difference in resistance between the two loops, the current resistance value R of the body circumference sensing segment a67 can be approximately obtained. m This allows the wearer to calculate the calf circumference based on the resistance value.

[0132] Furthermore, since the calf circumference also changes when the wearer makes ankle movements, detecting R... m The changes can also be used to assist in detecting the wearer's ankle joint movements. Similarly, this is also a manifestation of the distributed strain sensor used in the embodiments of the present invention for distributed strain detection.

[0133] In one embodiment, a seventh sensing area q7 is further included; the seventh sensing area q7 is arranged on the pants 10 corresponding to the position of the back of the lower leg of the human body and is located between the fifth sensing area q5 and the sixth sensing area q6.

[0134] Specifically, the three concentrated sensing areas 211 arranged corresponding to the position of the back of the lower leg of the human body can more accurately obtain the activity of the position of the lower leg of the wearer.

[0135] In a more specific embodiment, the fifth sensing area q5 and the seventh sensing area q7 are arranged on the left and right sides of the position of the back of the lower leg of the human body respectively; the sixth sensing area q6 is arranged between the fifth sensing area q5 and the seventh sensing area q7; the conductor line 212 connected to the sixth sensing area q6 is arranged side by side with the conductor line 212 connected to one of the fifth sensing area q5 and the seventh sensing area q7 away from the interface area 213. That is, the conductor line 212 connected to the sixth sensing area q6 is arranged side by side with the conductor line 212 connected to the seventh sensing area q7, so that the conductor lines 212 connected to the seventh sensing area q7 and the sixth sensing area q6 span the left and right sides of the lower leg.

[0136] Specifically, the conductor line 212 further includes a ninth line a9; the ninth line a9 is arranged side by side with the eighth line a8 in parallel and is connected to the sixth sensing area q6 and short-circuited with the eighth line a8. One end of the seventh sensing area q7 is connected to the ninth line a9, and the other end is connected to the eighth line a8 through the ninth line a9. Thus, by measuring the resistance of the loop composed of the eighth line a8 and the ninth line a9, the total resistance composed of the seventh sensing area q7, the eighth line a8 and the ninth line a9 can be measured. Then, by measuring the loop composed of the seventh line a7 and the eighth line a8, the line resistance composed of the seventh line a7 and the eighth line a8 can be measured; and then the resistance value of the seventh sensing area q7 is converted.

[0137] In other embodiments, the loop extension direction of the fifth sensing area q5 and the seventh sensing area q7 is consistent; the loop extension direction of the sixth sensing area q6 is perpendicular to the loop extension direction of the fifth sensing area q5 and the seventh sensing area q7.

[0138] Specifically, the loop extension direction of the fifth sensing area q5 and the seventh sensing area q7 can be along the vertical direction; the loop extension direction of the sixth sensing area q6 can be along the horizontal direction. Thus, the detection area of the lower leg position composed of the fifth sensing area q5, the sixth sensing area q6 and the seventh sensing area q7 can have higher sensitivity in both horizontal and vertical directions.

[0139] Further, at least one of the conductor lines 212 connected to the partial or whole of the concentrated induction zones 211 is shared by the adjacent concentrated induction zones 211. For example, the ninth line a9 is shared by the seventh induction zone q7 and the sixth induction zone q6.

[0140] In one embodiment, the conductor lines 212 further include a tenth line a10; the tenth line a10 is connected to the fifth induction zone q5 and is short-circuited with the fifth line a5 and the sixth line a6 and is arranged in parallel side by side. The fourth induction zone q4 is connected to the tenth line a10 at both ends. That is, the fourth induction zone q4 shares the tenth line a10 with the fifth induction zone q5. Such an arrangement, on the one hand, does not affect the resistance measurement of each concentrated induction zone 211 and facilitates the neat arrangement of the lines, and on the other hand, can reduce the number of conductor lines 212.

[0141] For example, when measuring the resistance of the fourth induction zone q4, the total resistance of the fourth induction zone q4 and the lines can be obtained by connecting the fifth line a5 and the tenth line a10, and then the resistance of the lines themselves can be obtained by connecting the fifth line a5 and the sixth line a6, so that the resistance of the fourth induction zone q4 can be calculated.

[0142] Compared with the inertial motion capture device in the prior art, the motion sensing trousers provided by the application have the advantages of high precision and no cumulative error; compared with the optical motion capture device in the prior art, in the case of having the same level of precision and low delay characteristics, and without the need for a special site to build an optical tracking device, the application greatly reduces the use cost and can accurately map the human motion without complex data operation, thereby having strong real-time performance, and in addition, the application can also solve the problem of positioning loss caused by shielding in the optical motion capture device in the prior art.

[0143] In another aspect, the application also provides a motion sensing system, which comprises the motion sensing trousers described in any of the above embodiments, and further comprises a data box 30. The data box 30 is provided with a processor 31, a data acquisition module 32 and a communication module 33.

[0144] The processor 31 is connected to the distributed strain sensor 20 through the data acquisition module 32, so as to obtain the electrical performance parameters of the distributed strain sensor 20 after deformation and calculate the result of the deformation of the simulation trousers 10.

[0145] In addition, the processor 31 can also be connected to the upper computer 40 through the communication module.

[0146] In application, the data box 30 can also be provided with an IMU module, and based on the IMU module, the position information of the motion sensing trousers in space can be obtained, so as to combine the inertial motion capture technology with the detection mode of the distributed strain sensor 20 in the above embodiments.

[0147] In the application, the optical capture device can also be connected by the host computer 40, and the position information of the motion sensing trousers in space can be obtained based on the optical capture device, so as to realize the combination of the optical capture technology and the detection mode of the distributed strain sensor 20 in the above embodiment. Compared with the traditional optical motion capture scheme, the number of cameras and marker points can be greatly reduced.

[0148] The host computer 40 can be a control terminal connected in communication with the data box 30, such as a mobile phone, a computer, and the like, or a cloud or other form of processing device, without limitation.

[0149] The above is only a preferred embodiment of the present application and does not limit the present application. Although the present application is described in detail with reference to the examples, those skilled in the art can still modify the technical solutions described in the examples or make equivalent replacements for some of the technical features, but any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
