The laser emitting cylinder 42 can emit a laser spot, and the rotating member 2 can adjust the angle of the laser emitting cylinder by adjusting the connecting member 3. The laser point coordinate adjusting component can finely adjust the position of the laser point in the x and y coordinate directions.
Referring to fig. 4, in the embodiment, the image recognition and voice prompt unit includes an intelligent image recognition device and a telescope 7 for recognizing the arrow target, the intelligent image recognition device is a mobile phone 5 in the embodiment, and the telescope 7 is aligned with the rear camera of the mobile phone. In use, the handset 5 is placed in the middle of a retaining clip 6 and secured, the telescope 7 is clipped onto the rear camera of the handset 5, and the tripod 8 is then opened to stand on the ground.
The following describes a specific auxiliary archery method using the above auxiliary archery system, and with reference to fig. 2, the specific process and operation method are as follows:
step S1, hardware installation and software setting: the assistant first performs system setup, which includes hardware installation and software setup. The hardware installation comprises the installation of an auxiliary aiming unit A and an image recognition and voice prompt unit B. Image recognition and voice prompt unit B includes installs cell-phone 5 on a fixation clamp 6, presss from both sides telescope 7 on cell-phone 5 rear camera, and cell-phone 5 embeds auxiliary software, can discern the arrow target position under the help of telescope 7, and fixation clamp 6 places on a tripod 8. The auxiliary sighting unit is then mounted on the bow by means of bolts, and the auxiliary sighting unit a is matched with the bow in balance by adjusting the adjustable mounting part 1, the rotating part 2 and the like.
The assistant then initiates a setup installation of the software, including a selection of usage scenarios, e.g., whether a 10-meter or 18-meter arrow target; focusing of the lens; and calibration of the shooting target. The built-in software of the mobile phone 5 can generate a circle mark, and the mobile phone 5 is moved to a proper position according to the direction of the arrow target, so that the arrow target can fall in the circle mark.
Step S2, the visually impaired person takes the bow and the arrow to aim at the arrow target: after the software and hardware installation and debugging are completed in the step S1, an assistant gives the bow and the arrow to the visually impaired, the visually impaired is guided to a proper standing position and a proper standing direction by matching with a common auxiliary standing frame in a shooting range, the laser emitting device 4 is opened, and the laser point can fall into the circle mark after the visually impaired lifts the bow. The visually impaired people wear the wireless earphone connected with the mobile phone to wait for the voice prompt.
Step S3, the visually impaired people adjust the auxiliary aiming unit or the bow and arrow position according to the prompt of the image recognition and voice prompt unit: the method specifically comprises the following steps:
step S31: the built-in software of the mobile phone 5 can carry out image identification, namely, laser points are detected;
step S32: after the laser spot is detected, the built-in software of the mobile phone analyzes the position of the laser spot, and when the laser spot falls in the arrow target, the distance between the laser spot and the center of the arrow target is calculated; when the laser spot falls outside the arrow target, the orientation of the laser spot relative to the arrow target will be analyzed.
Step S33: the results are prompted to the user in a voice mode, and the user adjusts the bow lifting position to an expected position after hearing the prompt of the earphone;
step S34: the user determines whether the target is substantially aligned according to the voice prompt, and if the target is substantially aligned, the next step is performed, and if the target is not substantially aligned, the step S33 is repeatedly performed.
And step S4, finishing archery by the visually impaired.
Step S5, the software built in the mobile phone detects the archery result and prompts the user with voice.
In order to make the archery skill of the visually impaired people continuously improve through long-term training, the method can further comprise the following steps:
and step S6, the archery result and the laser point position analysis result are sent to a big data system for data acquisition, and after the big data system analyzes key data indexes, the analysis result is displayed and fed back to the user and a coach, so that the coach can guide with reference, or the user can adjust the score influence factors such as the standing posture, the gesture and the like. In addition, the visually impaired can adjust the landing position of the laser spot by adjusting the rotating structure 2 and the laser spot coordinate adjusting device according to the performance of the visually impaired. In order to make the visually impaired people feel the adjustment each time, the rotating structure 2 and the laser point coordinate adjusting device can give out a prompt sound to help the adjustment when being rotated. Software can record the position and the angle of the laser emitting device 4 when the archery score of each user is good, and the laser emitting device 4 can be directly adjusted to the corresponding position according to the record when the user uses the bow, so that the bow is convenient and fast. The flexible adjustment mode can enable the visually impaired to quickly improve in each period of training.
It should be noted that, since more than one visually impaired person needs to use the bow in the training or competition field, in order to prevent the auxiliary device from being unable to identify the corresponding laser point, the laser emitting device used by each adjacent visually impaired person should carry a light source with different color, and the device only identifies the color emitted by the light source. For example, if the laser spot emitted from the laser emitting device used by the first visually impaired person is red, the laser spot emitted from the laser emitting device used by the adjacent visually impaired person is set to green.
In addition to the basic voice prompt feedback, each performance of the user is recorded in the software as a reference to allow the coach and visually impaired to clearly know the adjustments that need to be made in terms of gestures, stance and skill. Through setting, the software can record the results of the first training to the last training of the user and the point positions of the arrows on the arrow targets and generate a chart, so that the user can be guided to adjust the posture by data, the user can also know the progress speed of each stage clearly, and the potential of the user is stimulated to the maximum extent.
The software is also capable of switching between a training mode and a competition mode depending on the scenario. When the training mode is switched, the system can record all training conditions of each time, including training date, training times, training fields and the like, can also set a future training plan, and can set automatic voice broadcast reminding for the upcoming training to prevent missing; missed trains can be marked and time can be set to complement the trains, so that the continuity of the plan is kept.
Meanwhile, training and body data of all users, such as age, sex, height, weight, nationality, visual disability degree, scores and the like, can be stored in corresponding cloud terminals or servers, so that a coach or an assistant can conveniently manage and analyze big data of one or more regions, and further more accurately and comprehensively master the training frequency and target of the users. For example, the system may calculate the user's accumulated training duration, accumulated score, and suggest what level the user is currently in the area or around the world based on other user data already stored in the big data; if the user switches to the competition mode, the system records the data of scores of each competition of the user, ranks of the group games and the like, and the user can conveniently know the competition progress and results in real time. All data can be called by voice command.
The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. The equivalent substitution or change made by the technical personnel in the technical field on the basis of the invention is all within the protection scope of the invention. The protection scope of the invention is subject to the claims.
