Patent Application
20230096232
The present invention relates to a mobile apparatus and associated system that is completely or partially automated and is configured, in aspects, to measure sport surface (e.g., sport turf) characteristics and the safety of athletic apparel accurately and consistently in an apparel-to-surface interaction, in a manner that is quantifiable and repeatable. This application uses sport turf as an example but is not limited to sport turf, because the invention can be used with non-grass and non-turf surfaces using an appropriate foot form, instrumentation, and/or loads and motions particular to a certain sport (e.g., tennis, baseball, football, soccer, and so on). In examples only, sport turf is considered to be a naturally or artificially grassed surface and the immediate underlying environment, managed and prepared for fast and aggressive playing such as in American Football and Soccer. With reliable gameday, practice, or other data, causes and dangers of injury on natural or synthetic turf, using particular athletic apparel that interact with the turf can be better understood, predicted, and reduced through better field and apparel characterization and rating(s). Moreover, as described herein, the shoe/surface interaction contributes to athletic performance, which, according to the present invention, could also be better characterized, understood, predicted, and even enhanced.
Accurately and consistently quantifying turf conditions, as well as the effect of turf conditions on athletic apparel in situations and conditions that mimic athletic movement, can be used to reduce athletic injury occurrences, improve player performance, establish accurate, independent standards for artificial turf manufacturing, installation, and maintenance, prevent expensive stadium rework, and can lead to standardizing field and turf assessments across sports fields, including but not limited to American football and soccer, just to name a couple examples. With the instrumentation, system, products and methods described herein, and a sport-specific foot form, these tests could be performed on clay surfaces (e.g., baseball skins, warning track, tennis courts), hard surfaces (e.g., tennis, pickleball, volleyball, basketball), sand surfaces (e.g., beach volleyball, bocce, horse tracks), and other grassed (artificial or natural) surfaces such as horse tracks and cricket fields/pitches. With the present invention's instrumentation, the apparatus and system could also be used to quantify performance of a golf club or surface by characterizing a club to ground interaction, including an interaction that results in a portion of the playing surface being removed by the club head. Such testing may also be used in non-athletic environments where synthetic or natural surfaces are utilized. In order to accomplish adequate testing for quantifying turf conditions and effects of athletic apparel, the apparatus taught herein uses not only horizontal and vertical forces, but also torsional forces, and all three forces in combination at the same or different times. Thus, the apparatus and system can apply horizontal, vertical, and torsional forces, and link these forces together and combine them into a single motion to more closely mimic behavior of, for example, a human foot, leg, or entire body during an athletic movement, thereby applying and measuring interactions between all three forces at the same or different times.
Further, in embodiments, the system can be a platform for developing three-dimensional (“3D”) scanning and analysis techniques for turf and natural grass fields, among other possible scan targets. The different elements that make up the platform can expose universal, abstract interfaces so that new controllers, cameras, location systems, etc., can be switched in, swapped, or replaced at a later time. The analysis provided is, in aspects, meant to comprise expert-level analysis of every step of the process. The data provided can represent a host of introspective data so that the platform can diagnose issues or problems with the turf, fibers, grass, or in-fill. Knowing the data means the quality of the turf/grass/fibers/in-fill can be improved, thereby improving safety, aesthetics, or other parameters of the analyzed turf/grass/fibers/in-fill.
The system, in aspects, can be referred to as a mixed optical-depth estimation for field analysis that combines 3D surface scanning with optical images. The depth and optical data can be used together for more robust, height-aware, and color-aware measurements. Using the techniques described herein, a user can apply different kinds of data as filters in order to determine fiber height, infill evenness, grass coverage, fiber color, fiber wear, grass color, and more. In aspects, several industrial lasers, geared stepper motors, and one or more first-surface mirror are configured in a flat arrangement. In aspects, the camera that takes the optical image can also take the scan, and can therefore stitch them the images and/or scans substantially seamlessly. In aspects, the lasers can scan across the target at an angle so that the height of the target is shown as a divergence from the laser line to the camera.
In the National Football League (“NFL”), for example only, there is a significantly higher rate of non-contact injuries to lower limbs on synthetic turf than on natural turf (i.e., 28-69% higher). There have been ongoing attempts to determine why this is, however, the results are inconclusive. This suggests that the data currently being collected can be improved upon. Currently, typically before every game, the turf is manually inspected, and the data is recorded for reference if an injury were to occur.
While current on-field tests include impact hardness, infill depth and evenness, soil moisture content, surface shear resistance using a shear vane, percentage ground cover, visual inspection, and stability rating (post-game), the current tests have proven to be inconsistent, non-comprehensive, and subjective. Injuries continue to be a problem in all sports despite currently available safeguards, and a need exists for an improved way to attempt to decrease athletic injuries across all sports, especially those played on turf.
Due to the current limitations, it is an object of the current invention to allow for data collection on, for example, shoe-to-turf interaction while subject to applied forces in order to properly correlate injury to turf characteristics, and/or characteristics of the cleat or shoe. In aspects, data collection might include, for example, kinetic and kinematic data during the shoe-turf interaction, measurement of turf characteristics through additional measuring devices, and recording of characteristics of the shoe and/or turf used for the shoe-turf interaction test. Because of the capabilities of the current invention, when injuries occur, the incidence of injury can be traced back to the turf data or apparel data collected by the inventive apparatus and compared amongst other cases of injury or, alternatively, with cases of non-injury. Once common injury metrics or injury risks are established, by way of example only, mechanical parameters measured can be minimized in the manufacture of turf or athletic apparel, thereby reducing injuries based on quantifiable data. To accomplish this, the current invention is, in aspects, mobile and completely- or partially-automated, and configured to provide reliable data that is repeatable and reproducible.
It is an object of the current invention to test the safety of artificial or natural turf and/or athletic apparel, especially shoes including but not limited to cleats, using a shoe-surface tester that determines and analyzes the mechanical interactions between shoes and an athletic playing surface/turf and performs other measurements commonly taken on turf, and/or determines and analyzes whether the shoes and/or playing surface are up to standards and/or deemed safe for athletic events. The device simulates and measures shoe-to-turf interactions at loads and rates created or generated by athletes during performance up to and including those deemed to be injurious. This involves measuring displacement, velocity, and acceleration components of the shoe and/or foot form in all directions, as well as in rotation, and any combination of these forces at the same or different times. The apparatus may apply or measure all components (dx, dy, dz, rx, ry, rz) of six degrees of freedom forces and moments of the shoe and or foot form.
The apparatus may use a foot form connected to a system of nested frames or a Stewart platform to accomplish this. Thus, the cleat is actuated through its prescribed load or positional path by a mechanism capable of imparting and withstanding the significant forces and moments without unwanted mechanical deformation, friction, or fatigue that might otherwise influence the data collected. The apparatus or related system is not required to use a foot form or necessarily to measure or analyze a playing surface as it relates to interaction with a foot, cleat, or other playing apparel. For example, in embodiments, the device may also automate or assist with:
It is a further object of the current invention to fully characterize turf in a way sufficient to direct changes to the turf and/or shoes for improved performance and/or injury prevention. This mechanism will incorporate all or part of the tests in a controlled manner. By actuating test modes, the system can rely on the data being consistent across stadiums as human-to-human variability inherent in testing with manually powered devices is removed from the process. For example, the system may automatically restrict or fix degrees-of-freedom as appropriate for the desired test mode. The system may also automatically raise or lower the footform for the test, as appropriate. The system may also incorporate locational measurements of the top surface of the test surface into test actuation or data processing. To maintain safety, the system may display the current “state” of the system (for example, whether the system is safe for manual operations or ready to complete a test).
In other embodiments, tests that can be automated are, by way of example only, surface hardness and/or energy absorption and/or return, infill depth and evenness, soil moisture content, surface shear resistance, and/or percentage ground cover detection. In addition to actuating tests, this improved system will also have temperature, pressure, and humidity sensors.
Finally, the device can utilize a translation-rotation foot-form that can be shod with various footwear that in turn can engage with the ground to analyze shoe or cleat release dynamics.
The foot-form is representative of an athlete's foot in a cleat or shoe and is interchangeable for customizability. This extremity may have roll, pitch, and yaw adjustability to collect data on varying cleat-to-turf interface angles, as well as allow adjustment in the angle of the “toe” of the footform relative to the rest of the footform to approximate flexion of the foot about the MTP joint, yet hold these adjustments fixed in a static pose while testing is occurring. This end effector will be attached to its translation and rotation actuation mechanism via a multi-axis load cell, in aspects. This load cell will collect force and moment data on the foot-form as it moves relative to the turf via, for example, a data acquisition unit. The data collector, such as a computer, will also be recording data from rotational and translational displacement sensors to detect linear position and velocity of the shoe as well as angular rotations and velocities of the shoe. Accelerations of the foot-form may also be measured to either characterize the interaction of the shoe with the turf or, alternatively, to allow characterization of the inertial effects of the device during testing.
In other embodiments, the invention described herein is an apparatus configured to apply controlled horizontal and vertical forces and rotational moments to an end effector (footform) as prescribed, wherein the applied forces and moments mimic a behavior of a human foot or other body part during an athletic movement or reflect forces and/or moments associated with injury and/or performance of a subject's foot or other body part (e.g., the loads generated by football players in the NFL), wherein applying and measuring interactions between prescribed forces, rotational moments, and rotational and linear displacements allows for a safety and/or performance evaluation of a subject, athletic apparel, or an athletic playing surface.
In another embodiment, the invention described herein is an apparatus configured to apply controlled horizontal, vertical, and/or rotational displacements to an end effector (footform) as prescribed, wherein the applied displacements mimic a behavior of a human foot or other body part during an athletic movement or reflect displacements associated with injury and/or performance of a subject's foot or other body part (e.g., motion profiles resulting from athletic tasks resulting in foot/surface interaction during football playing), wherein applying and measuring interactions between prescribed forces, rotational moments, and rotational and linear displacements allows for a safety and/or performance evaluation of a subject, athletic apparel, or an athletic playing surface.
The accompanying drawings illustrate certain aspects of embodiments of the present invention and should not be used to limit the invention. Together with the written description the drawings explain certain principles of the invention.
Reference will now be made in detail to various exemplary embodiments of the invention. It is to be understood that the following discussion of exemplary embodiments is not intended as a limitation on the invention. Rather, the following discussion is provided to give the reader a more detailed understanding of certain aspects and features of the invention.
The present invention can be described in terms of, for example, a foot-form assembly that is preloaded into the ground or turf sample via a tunable vertical load actuator. The apparatus and associated system can impose a constant and/or dynamic or variable horizontal force (and/or rotational torque) on the foot-form assembly while collecting motion profile data on the cleat/shoe as it engages and releases from the turf In addition to measurement of the displacements associated with applied forces, the system is also capable of logging the minimum required force required to achieve such release from the turf fibers, infill, and overall construction. The minimum force required for cleat/shoe motion relative to the turf matters because this value potentially represents the forces that a player's leg or other body part will experience when loaded in a similar manner to an athlete representative system. This data, along with existing tests results (which will be automated, in aspects), will all be recorded and saved, in aspects. This data can be used to identify the differences in quality of synthetic turf, and the quality of athletic apparel, during injury (or non-injury) compared to the characteristics of natural turf, synthetic turf, non-injury situations, and/or safer or less safe athletic apparel. In addition to data collected during the shoe-turf interaction test, characteristics of the shoe or turf used for the test can be saved and linked with the test data.
The current invention allows for closed-loop control, wherein the system is capable of monitoring force or torque being applied and controlling the force or torque in order to, in aspects, maintain a constantly applied force or torque in a controlled and constant manner. However, in aspects, the apparatus does not necessarily need to provide force or torque in a constant manner and situations may arise where force or torque will not be applied in such a manner; rather the applied force or torque will be variable and/or adjustable. In aspects, the system measures impedance, such that it applies displacement or velocities and measures forces/torques, for example. The system may also apply and measure admittance, therein applying a force/torque and measuring displacement or velocity; thus, the system may be configured to apply a particular force/torque in order to measure the impact on, for example, an athletic shoe, a human body or body part, and/or real or synthetic turf.
In some instances, the system will use prior data knowing what forces or torques typically, usually, or sometimes cause injury in order to maintain input force/torque applied by the apparatus to determine displacement or movement of a shoe, in aspects, for a given shoe-to-turf combination(s). In embodiments, this may result in a rating or ranking of a shoe and/or turf; in aspects, it can be a pass/fail test, meaning a determination is made whether an athlete can use a particular shoe or not (is it safe, or less safe, or is it unsafe?). Also, based on test results with a given cleat, shoe or generic representation of a shoe-turf interface, the system can verify condition and maintenance of a field, e.g., within tolerances.
In aspects, the current invention tests mechanical interactions between the cleat-or shoe-to-turf interface using a translation test and a rotation test, and force and motion data are recorded via data acquisition, and therefore the system is capable of recording accurate and repeatable results. In aspects, the apparatus is configured to collect on-field displacement, velocity, force and torque data, record impact hardness, measure infill (turf), analyze surface stability (grass), read surface moisture content, perform visual inspection (e.g., via camera or drone), and/or upload or download data manually or automatically.
In aspects, the apparatus processes and displays data tailored for a certain target audience. In aspects, there might be some “hard-coded” data with some data analysis built in locally, remotely, or on a server. In another example, the analysis may be performed online via analysis of metadata stored in a server.
The system is capable of objectively scoring surfaces and footwear, and evaluating geographical compliance of a surface with a standard or protocol (using, for example, GPS to evaluate an entire field area or a portion of a field area and recommending localized intervention/maintenance).
Turning to the figures, in
In
In further regards to video and computer-implemented visual inspection/analysis of one or more aspects of the turf, including the surface of the turf, which does not necessarily require a foot form or need for interaction of a foot form with the playing surface (e.g., grass or artificial turf), for the purpose of, for example, determining the quality or safety of the turf, aspects of the invention include the following. In embodiments, the invention is a measurement system for repeatably measuring and quantifying turf surface characteristics. Typically, the surface characteristics of artificial turf and natural grass are evaluated and given a rating by an expert in evaluating turf/grass, but the current system can produce repeatable results that can, in aspects, both rate and explain the rating of a surface. In aspects, the system can provide specific/objective results for rating the turf, and do so in a manner that is consistent across different surfaces and across different locations. Accordingly, a result achieved by this system is to extract measurements of turf and natural grass characteristics using a variety of computer vision techniques.
In some cases, such measurements would be difficult or unstable with optical measurement alone. Others would not necessarily be captured accurately using three-dimensional (“3D”) scanning. Thus, in aspects, the system can use a single camera, but is not limited to a single camera, to create a combined “optical space” and “depth space” measurement. Additionally, multiple scans can be used for the depth-space image and/or multiple images can be taken with different lighting for optical-space images.
In embodiments, the system can comprise, for example:
In an aspect, more than one laser (e.g., four lasers) orthogonal respective to one another surround a lighting source and camera, such as a light ring and industrial camera. In aspects, the light ring turns on to light the surface and the camera takes the optical image. Then the ring turns off and each laser scans across the surface while being recorded by the same (or a different) camera. Optionally, another optical image is taken after the scan so that the two optical images can be analyzed for differences to account for anything that may have moved during the scan.
In an embodiment, four lasers are used to create four depth maps. The lasers can be mounted facing out and can be bounced off of a spinning mirror into the scan area. Each laser assembly, in aspects, includes a blue laser and a red laser. The blue laser can be chosen automatically if there is too much red in the optical image, which can act to reduces scattering and thereby provide a sharper image on red and orange surfaces. In aspects, stepper motors are used, wherein the stepper motors can have a planetary gear set with a high gearing, such as, by way of example only, 64:1 or 90:1, to offer high and repeatable accuracy once backlash is corrected for. In aspects, the stepper motors can be used to align or aim the mirror(s) to direct the laser(s).
In aspects, any warp of the camera lens is treated/removed using a checkerboard grid. In aspects, then the laser scans are compiled, with the pixels where the laser is seen “tagged” with the depth measurement at that spot. In aspects, the laser scan frames can be stitched together into a depth map by taking the max height for each pixel in the frame during the scan. In aspects, individual lasers contributing to the resulting depth map can be color-coded, and therefore the lasers can fill in each other's shadows and they can see/sense the tips of the fibers.
In aspects, using a single camera, because the scans and the optical images are taken from the same camera, the images can be overlaid, such as exactly or nearly exactly overlaid. In some embodiments, the total entropy in the image is measured, which can assist with quantifying measurement accuracy and/or surface complexity.
If it is desired to measure and understand characteristics of the turf/fiber/grass, the system preferably can accurately separate/delineate the (a) turf/fiber/grass from the (b) infill/dirt. In aspects, it can be easier to make that distinction in the optical image as compared to the depth image. Accordingly, in aspects, the depth image is used to sample the turf/fiber/grass first, but not always. In embodiments, that color sample can be used to find the rest of the fiber in the image and/or scan. According to this process, a mask is created, sometimes referred to as the fiber mask, which is an important component output of the system, because it can allow a user to determine more information/measurements about the turf/fiber/grass and infill/dirt individually and/or separately.
Using the fiber mask to isolate the two components of the surfaces, the system can now expand the measurements to a host of new measurements, such as:
In aspects, the system determines features of the grass/turf/fibers/in-fill that can be reliably extracted, and several different ways of presenting each feature are presented to a user (e.g., a single metric, a distribution, distributions over time, and others) so that the user can understood, troubleshot, and integrate partial data into the rest of the data from the system.
In aspects, in order to ensure that the depth measurements are accurate using the system, a “calibration square” is scanned as part of a one-off calibration routine for machine setup. If the shape or form-factor of the machine changes, this calibration can be redone. Otherwise, one calibration can, in aspects, be useful for the life of the machine. In aspects, the calibration square can be a 150 mm×150 mm square with a 25 mm lip on an edge. It can be used as a known reference target and to deduce laser position and depth.
An example of the Calibration Routine is as follows: first a calibration square is place into a calibration frame, which positions the square in the center of the frame and orthogonal to the one or more lasers. In cases, one or more corners of the square is located/determined and the image is warped so that the square fills the frame. This can ensure that the scans are orthogonal to the frame an in alignment with the one or more lasers. Once the square is isolated, known aspects of the dimensions of the square can be used to measure what is being seen/sensed across the scan, extracting laser position and step from each frame. A line can then fit to each of the two in order to create a map of where the laser is over time in a scan; in other words, the position of the laser over time, in aspects, will form a line, which can be fit in order to model the laser position over the time of the scan, which can allow for deduction of depth by measuring how far the laser diverges from that predicted position. These line-of-best-fit equations can be saved in a calibration file and can be used to model where lasers are in the frame over time for future scans.
In embodiments, the menu user interface can allow a user to run scans, recalibrate the system, run analysis separately from scans, and run tests. It can, in aspects, also automatically update the code and the controller on start-up. Features include, but are not limited to:
The following is by way of example only and is not limiting to the scope of the present invention described herein.
