Embodiment 1

[0038] The invention provides an adaptive archery auxiliary training system, which combines figure 1 As shown, the adaptive archery auxiliary training system includes an information processor for calculating and analyzing data;

[0039] An image collector, used to collect real-time images of the target;

[0040] Sensors to measure the state of the bow;

[0041] A prompter, used to guide archers to adjust the bow;

[0042] The sensor includes a gyroscope, the gyroscope is installed on the bow arm of the bow, and is used to measure the real-time attitude angle of the bow;

[0043] When the archers carry out archery training, the image collector collects the information of the target surface in real time, the gyroscope measures the real-time attitude angle of the bow, and the information processor controls the image collector and the gyroscope The collected information is processed, including identifying the ring number of the drop point on the target, analyzing the position o...

Embodiment 2

[0050] Like the adaptive archery auxiliary training system described above, the difference in this embodiment is that the information processor measures the current attitude angle of the bow according to the gyroscope and the target angle collected by the image collector. Number of rings, calculate and analyze the proper angle between the bow and the horizontal direction when the arrow points to the bull's-eye, and guide the archers to adjust the bow according to the said proper angle. The specific steps are as follows:

[0051] After the archer stands at a fixed position, he shoots multiple arrows at the same shooting point arbitrarily at the target, defines the x-axis as the axis perpendicular to the target surface, the gyroscope measures the attitude angle of the bow that shoots the arrow, and the image acquisition The device collects the position of the falling point and the bull's eye on the target;

[0052] The information processor randomly selects multiple groups from th...

Embodiment 3

[0058] As the adaptive archery auxiliary training system described above, the difference of this embodiment is that, in combination with figure 2 and image 3 As shown, the information processor can calculate the distance between the drop point of the two arrows, the bull's-eye and the projected point perpendicular to the target surface, and the angle relationship between the interconnected lines. The calculation method is:

[0059] The initial coordinate system of the bow is defined as the x-axis is perpendicular to the wall where the target is located, and the y-axis and z-axis are respectively perpendicular to the x-axis and horizontal and vertical coordinate axes; according to the position of the shooting point T on the bow and the level of the target The distance y, the angle tanα and tanβ between the shooting direction of the arrow and the horizontal x-axis, can calculate the distance between the two landing points A and B of the two arrows on the target and the project...

Abstract

The invention discloses a self-adaptive archery auxiliary training system which comprises an information processor, an image collector, a sensor and a prompter; the sensor comprises a gyroscope whichis arranged on the bow arm of the bow and is used for measuring the pose angle of the bow in real time, the image collector is used for acquiring the target surface information, the information processor analyzes, calculates and judges the information acquired by the gyroscope and the image collector, the prompter guides the shooting action of the archery personnel; The system guides the shootingaction of the archery personnel through the information processor, the image collector, the prompter and the sensor, and the pose angle of the bow is measured by arranging the gyroscope on the bow arm, the system has a simple structure, is not easy to loosen, is convenient to install and adjust, and reduces the cost.

Description

technical field [0001] The invention relates to the field of archery training, in particular to an adaptive archery auxiliary system Background technique [0002] Bows and arrows have been tools that human beings have relied on for survival since ancient times. Even today, bows and arrows are still widely used in sports, entertainment, hunting and other fields. Long-term practice is required to master the skills necessary for archery, and slight changes in movements will lead to large changes in shooting points. Therefore, long-term one-on-one coaching and correction by coaches is often required in the training process, and the teaching cost is very high; for novices Or for people who want to experience bow and arrow sports, poor performance when they first get in touch with bow and arrow will lead to poor archery experience, and auxiliary means are needed to improve the experience of this sport. At the same time, the auxiliary equipment that has appeared so far is mainly ...
