[0002] In traditional basketball sports training, when facing the defense of the defensive players, the offensive trainees are trained to dribble and break through. In this training process, the defensive trainees have to keep moving with the offensive trainees, and the offensive trainees have to determine their own offensive direction according to the moving direction of the defensive trainees (external stimulation).

[0003] However, in the actual training process, the defensive trainer is usually replaced by a fixed object, which is different from the real defensive trainer who keeps moving. Offensive trainers often rely on their own initiative or the route direction set by the coach to decide the direction of attack. If you want to break through from the left, go to the left. Even if there is a real defensive trainer accompanying the training, the offensive trainer can make the best attack according to the defensive trainer's movements, but it is impossible to measure the time to complete each attack and quantify the training indicators.

[0029] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-10 , the embodiment of the present invention includes:

[0031] An agility training and testing device is a training instrument and equipment based on a time-of-flight sensor, an AI camera, and a multi-color indicator device to realize the quantitative training and testing of multiple functional agility of trainees. Its structure includes: a host device 101, an indicator detection device 102, and a timer device 14. The indicator detection device is arranged on the left and right sides of the host device through magnetic contacts, and the back of the host device is detachably provided with the timer device. The host device is connected to an intelligent terminal APP through wireless communication, and the collected training and test results are uploaded to the intelligent terminal APP for analysis. The user can set the exercise mode, parameters, etc. in the APP.

[0032] The host device can be directly installed on a wall, the ground or other existing objects, or can be set on a fixed bracket to meet different usage environments.

[0033] The host device includes: a host housing, a stepper motor 1, a camera 2, a lithium battery 4, a stepper motor bracket 10, a main circuit PCB 12, a plane thrust bearing 25, a straight infrared laser transmitter 27, a rotating bracket 28, a 3D camera (or a 3D image capturing device such as a 3D camera) 29, and a speaker 18.

[0034] The host housing is enclosed by a left shell 3, an upper shell 13, a rear shell 17, a right shell 21, a lower shell 26, and a front shell 30. The left shell and the right shell are provided with storage slots for storing the placement indication detection device, and the magnetic contact and the speaker are provided in the storage slots.

[0035] When the indication detection device needs to be unfolded for use, the bottom of the indication detection device is magnetically connected to the host device, so that the indication detection device is opened and stands upright in the storage slot. When the indication detection device is not needed, the indication detection device is horizontally embedded in the storage slot for easy storage and carrying.

[0036] The lithium battery and the stepper motor bracket are arranged in the host housing, the camera and the main circuit PCB can be arranged on the stepper motor bracket or the host housing, the main circuit PCB is respectively connected to the stepper motor, the camera, the lithium battery, the infrared laser transmitter, the 3D camera, and the speaker, the main circuit PCB can be electrically connected to the indication detection device and the timer device, and can also communicate with the indication detection device and the timer device wirelessly or by Bluetooth, so as to facilitate the separation of the indication detection device and the timer device for use.

[0037] The infrared laser transmitter is fixed at the center of the rotating bracket, and can emit training light to indicate the direction of the trainee's moving position. Figure 3 As shown, the projection direction of the one-line infrared laser can be downward (i.e. the laser emitting end is facing downward), so that the training light can be projected onto the training ground or object, which is convenient for users to use for training. The 3D camera is arranged on the side of the rotating bracket, and the direction of the lens of the 3D camera is consistent with the direction of the training light emitted by the one-line infrared laser emitter, so as to obtain or detect the real-time position and 3D image of the trainee.

[0038] The 3D camera can generate low-pixel distance images and detect the distance between the trainee and the 3D camera, based on which the trainee's body movements can be analyzed. This is something that ordinary cameras cannot do. In combination with camera 2, the trainee's posture and technical movements can be analyzed to determine the standardization of the trainee's movements. For example, the time when the trainee's soles touch the ground during the movement cannot be simply measured using camera (2). The trainee can replay the movement to see if the details of his or her technical movements are standard, and continuously improve the level of his or her technical movement details through repeated training.

[0039] One or more cameras 2 can take video. The host device supports recording with an external smart device or other device with a camera function, and uploads the image to the APP software of the smart device for image AI analysis and calculation. Combined with the distance image of the 3D camera or 3D camera, intelligent analysis is performed to determine whether the details of the trainee's technical movements are standard.

[0040] The rotating bracket is rotatably connected to the lower shell through the plane thrust bearing, and the rotating bracket is placed on the plane thrust bearing and then placed on the bottom fixing ring plane of the main body shell. The stepper motor is arranged on the stepper motor bracket, and the rotating bracket is connected to the output shaft of the stepper motor. The stepper motor drives the rotating bracket to rotate according to the required angle, and drives the infrared laser transmitter and the 3D camera to rotate together. The bottom surface of the lower shell is provided with an opening to allow the infrared laser transmitter to pass through or extend, and the side wall of the lower shell is provided with an opening to cooperate with the 3D camera.

[0041] The structure of the indication detection devices on the left and right sides is the same. The indication detection devices include a lampshade 24, an indicator light, a lamp PCB board 23, a first flight time sensor 20, a second flight time sensor 22, and a lamp back cover 19.

[0042] The lampshade and / or the lamp back cover are magnetically connected to the main body shell. In order to further improve the accuracy and stability of the connection, one or more positioning pins are arranged in the storage slot, and the lampshade and / or the lamp back cover are provided with positioning holes that are plugged into the positioning pins.

[0043] The light PCB board connected to multiple indicator lights is arranged on the back cover of the lamp, and the lampshade is covered on the indicator lights and the light PCB board. The first flight time sensor connected to the main PCB and the second flight time sensor connected to the light PCB board are arranged front to back, so that there is a certain front to back distance between the first flight time sensor and the second flight time sensor, and the first flight time sensor is arranged on both sides of the main body shell (can be directly arranged on the left shell and the right shell, or arranged in the storage slot), and the second flight time sensor is arranged on the outside of the lampshade or the back cover of the lamp, so that the trainee can pass through the two flight time sensors in succession to calculate the trainee's instantaneous speed.

[0044] The indicator detection device can also have a built-in battery for long-distance or independent use. The indicator light can be composed of red, green and blue LEDs to display three indicator lights to achieve different mode combinations. The time-of-flight sensor can sense approaching objects to extinguish the indicator light. The time-of-flight sensor can also be used to obtain a variety of parameters such as the trainee's movement speed, acceleration, and distance from the host.

[0045] A time-of-flight sensor (ToF) can measure the time it takes for an object to propagate through a medium. Typically, it is a measure of the time that passes between a single-photon laser pulse emitted by a time-of-flight sensor (ToF) and reflected from an object and returned to a single-photon avalanche diode of the ToF sensor. A time-of-flight camera is a device that uses ToF measurements to determine a single-point distance between the camera and an object or environment, and creates an image generated by an integrated dot matrix of individually measured points. It is currently widely used in fall detection, drones, obstacle avoidance, and unmanned driving.

[0046] The timer device 14 can be an existing timer, or can include a timer housing and a timer PCB disposed in the timer housing. The intuitive time indication can make the trainee's training test results clearer. The timer device and the host housing can be connected in a variety of ways such as bolts and magnetic suction. The timer device can receive and display the timing of the host through Bluetooth / wireless connection, and can be placed in a convenient place for the trainee to observe the test time results. Specific embodiment 1

[0048] This device is used to train basketball offensive trainers. Since the host device randomly provides the offensive direction, the offensive trainer does not actively decide the offensive direction. The trainer needs to judge, start, and run offensively according to the random indicator light direction prompts and the action technical specifications. The agility of the movements of professional trainers after long-term training is much faster than that of ordinary people.

[0049] See also Figure 6 and Figure 7 The host device is set on a fixed bracket, and the training starting distance is set by the smart device. Each training starts from this reference point; after the 3D camera 29 senses the trainee in the starting range, the controller (main circuit PCB) inside the host device randomly generates an attack direction (left or right) within a random time (about a few seconds to more than ten seconds), and the indicator light indicates the attack direction (left or right), and the speaker voice prompts the start of the test; the timer starts timing when the indicator light lights up, and the offensive trainee starts dribbling and breaking through in the direction indicated by the indicator light; when the offensive trainee moves to the side of the host device in the indicated direction, the two flight time sensors on the same side as the indicated direction both sense the passage of the object, and the timer ends at this time, and the timer panel displays the time when the offensive action is completed.

[0050] There are two time-of-flight sensors on the side (taking the right side as an example). The trainee first passes through the second time-of-flight sensor 22 and then passes through the first time-of-flight sensor 20. The distance (D) between the two time-of-flight sensors and the interval time (Δt) of the trainee passing through the two time-of-flight sensors can be used to obtain the instantaneous speed (V) of the trainee when passing through the side of the host device and the distance between the trainee and the host. The host device uploads the acquired and calculated information to the smart device as analysis data.

[0051] The offensive trainer can intuitively see the specific reaction time of his / her dribbling offensive action and the comparative analysis information of his / her posture and technical action. When the offensive trainer returns to the front of the host device, if the trainer is within the sensing range of the 3D camera 29, a new round of training can be started again. The test reaction time is continuously obtained, combined with the offensive trainer's technical actions, the standardization and consistency of the technical actions are continuously improved, and muscle memory is formed to finally achieve the training purpose. Specific embodiment 2

[0053] This device combines the instructions of infrared laser to further complete the basketball dribbling fake turn training test. In actual sports, the dribbling offensive trainer needs to use fake moves to lead the defensive trainer away from the path where the offensive breakthrough is required, and then the offensive trainer quickly returns to the position to break through. In order to strengthen the training of this mode, the following mode combination is formulated.

[0054] See also Figure 8 If the trainee is within the sensing range of the 3D camera 29, the infrared laser emitter 27 at the bottom of the host device can rotate and randomly emit linear light for indicating the direction of the fake offensive action. The timer starts timing when the linear light is emitted; the trainee must follow the linear light while dribbling and attacking, and reach the position indicated by the linear light; when the 3D camera with the infrared laser emitter 27 rotating detects that the trainee has reached the direction indicated by the infrared laser emitter 27, the indicator light on the opposite side of the linear light lights up, and the trainee needs to stop and change direction in an emergency, turn to the direction indicated by the indicator light, and pass through the lighted side of the host device; when the flight time sensor on the lighted side senses that the trainee has passed, the timer ends, and the time when the offensive action is completed is displayed on the timer panel.

[0055] There are two time-of-flight sensors on the side (taking the right side as an example). The trainee first passes through the second time-of-flight sensor 22 and then passes through the first time-of-flight sensor 20. The distance (D) between the two time-of-flight sensors and the interval time (Δt) of the trainee passing through the two time-of-flight sensors can be used to obtain the instantaneous speed (V) of the trainee when passing through the side of the host device and the distance between the trainee and the host. The host device uploads the acquired and calculated information to the smart device as analysis data.

[0056] The offensive trainer can intuitively see the specific reaction time of the offensive action and the comparative analysis information of the posture and technical action. When the offensive trainer returns to the front of the host device, if the trainer is within the sensing range of the 3D camera 29, a new round of training can be started again. Specific embodiment three

[0058] The straight infrared laser emitter 27 can emit linear light indications at different time intervals; the trainee must dribble and follow the linear light to reach the position indicated by the linear light; the straight infrared laser emitter rotates randomly, so that the linear light reaches different positions left and right, and the trainee needs to dribble left and right to follow the movement, simulating the defensive trainee following the left and right movement of the offensive trainee, and at the same time the 3D camera 29 detects the degree of synchronization of the trainee following the light.

[0059] See also Fig. 9Yes, during the left and right movement, the 3D camera 29 detects the distance between the trainee and the 3D camera in real time. When the distance change exceeds the preset threshold range, it is determined that the trainee has not kept up with the movement of the linear light, and the host device will emit an audible and visual prompt, indicating that the tracking has failed. The host display will also display the time from the start of the movement until the time when the trainee leaves the direction indicated by the linear light, and the time when the trainee leaves the tracking will be used as the training test result.

[0060] In addition, the linear light emitted by the infrared laser transmitter 27 can also be used as an interference light beam, and the attack trainee should avoid the simulated obstacle formed by the light beam. Specific embodiment 4

[0062] The host device can also be combined with other equipment for training:

[0063] 1. Fixed unilateral attack training mode: The trainee's movement direction (left or right) is fixed, and the training starting position is indicated by the infrared laser transmitter 27. At the same time, the fixed start time can be used to solidify the existing technical movements through a large number of repeated training.

[0064] 2. Add different obstacles for interference training. Obstacles can include marker barrels at different locations or signs that need to be touched (or touched and popped out, etc.), physical buttons connected to the device, obstacles formed by electronic beams, etc.

[0065] For example, the training participants can obtain the test reaction time of passing the sensing point by combining plastic marker barrels placed in different positions and dribbling movements. Offensive athletes can also sequentially pick up or touch marker barrels at different positions / intervals, tap physical buttons, perform obstacle avoidance movements, and then pass the sensing point to test the time. During training, they can complete sports technical movements such as running, squatting, reaching high, and instant reversal.

[0066] 3. Set up multiple training and testing devices for combined training and testing. Trainees test the reaction interval time through different sensing points. Through different combinations, multiple training modes are formed to complete the agility training test on the entire attack path.

[0067] Adding more interference will increase the difficulty of training and testing. For various emergencies on the sports field, athletes should be able to deal with various emergencies and resist interference. It can also be used to train and test emergencies in various other scenarios to shorten people's response time.

[0068] The beneficial effects of the agility training test device of the present invention are:

[0069] 1. Through the cooperation of the host device, the indication detection device and the timer device, not only can a variety of different training structures and training programs be provided to meet different training and testing needs, but also the accuracy and efficiency of the training and testing can be greatly improved.

[0070] 2. It can accurately quantify the training and test the human body's reaction time, thereby improving human agility and improving one's own agility in sports, emergency response training or entertainment games.

[0071] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
