Description

射箭计分系统  Archery scoring system
技术领域 Technical field
本发明属于游戏娱乐的技术领域, 更具体的说本发明涉及一种射箭休闲娱 乐活动的射箭计分系统。  The present invention pertains to the technical field of game entertainment, and more particularly to an archery scoring system for archery recreational activities.
背景技术 Background technique
射箭运动有着悠久的历史, 在古代其作为一项生存的基本技能, 在人类社 会的发展中曾经起到了非常重要的作用, 现如今随着人类生活水平的提高, 射 箭运动逐渐发展成为一项娱乐休闲和体育竞技项目。 目前, 世界许多国家以及 我国的许多城市都将这项运动进行了普及性的推广, 并建立了射箭馆。 这项运 动的开展以及场地设施的建设, 不仅有利于专业运动员运动水平的提高, 而且 还提供了有利身心的娱乐活动。  The archery movement has a long history. In ancient times, it has played a very important role in the development of human society as a basic skill for survival. Nowadays, with the improvement of human living standards, archery has gradually developed into an entertainment. Leisure and sports competitions. At present, the sport has been popularized in many countries around the world and in many cities in China, and an archery hall has been established. The development of this sport and the construction of the venue facilities not only help the professional athletes to improve their level of exercise, but also provide recreational activities that benefit the mind and body.
通常, 射箭馆、 射箭休闲娱乐中心、 射箭训练场地的箭靶被设置在射击者 具有一定距离的地方, 并在若干射击通道中, 分别设置多个箭射靶。 由于距离 较远, 不容易观察射中的情况。  Usually, the archery of the archery hall, the archery recreation center, and the archery training site are placed at a certain distance from the shooter, and a plurality of arrow targets are respectively set in several shooting channels. Due to the long distance, it is not easy to observe the situation in the shot.
近几十年来, 为了提高竞技水平, 各国都加强了射箭运动的科学研究工作, 改进训练方法, 提高器械的质量, 射箭水平提高的很快; 其中自动定位、 识另 iJ、 报靶系统逐渐成为业内研究和开发的重点项目。 目前的自动定位识别报靶方法 主要有: (1 ) 光电自动报靶; (2 ) 超声传感器报靶; (3 ) 电子传感器报靶; (4) 摄像报靶等方法。 其中光电自动报靶方法乂分为红外、 激光和线阵 CCD三种, 但是光电自动报靶技术复杂, 价格昂贵, 不适宜用于射箭休闲娱乐活动。 超声 传感器报靶是瑞士设计的最先进的报靶系统, 具有精度高、 不受天气因素影响 的优点, 但是上述进口器材价格相当昂贵, 显然不适宜在休闲娱乐活动中推广 应用, 一般仅用于专业训练和高水平的竞赛选定用品; 而目前的电子传感器报 靶和摄像报靶不能实现自动报靶, 使得射箭计运动缺乏互动性, 显得枯燥乏味。 因此, 为了推广射箭运动必须从趣味性、 互动性和科学性出发, 彻底改变人们 对射箭运动的看法, 使得人们在休闲娱乐的同时还能够得到身心的放松。 In recent decades, in order to improve the level of competition, countries have strengthened the scientific research work of archery, improved training methods, improved the quality of equipment, and improved the level of archery. Among them, automatic positioning, identification, and reporting systems have gradually become Key projects in industry research and development. The current automatic positioning and identification reporting methods mainly include: (1) photoelectric automatic reporting target; (2) ultrasonic sensor reporting; (3) electronic sensor reporting; (4) camera reporting and other methods. Among them, the photoelectric automatic target reporting method is divided into infrared, laser and linear array CCD. However, the photoelectric automatic target reporting technology is complicated and expensive, and is not suitable for archery leisure and entertainment activities. The ultrasonic sensor target is the most advanced target system designed by Switzerland. It has the advantages of high precision and weather resistance. However, the imported equipment is quite expensive and obviously not suitable for promotion in leisure and entertainment activities. Applications, generally only used for professional training and high-level competition selection; while the current electronic sensor target and camera target can not achieve automatic target reporting, making the archery movement lack of interaction, it seems boring. Therefore, in order to promote archery, we must start from the fun, interactive and scientific, completely change people's views on archery, so that people can relax physically and mentally while enjoying leisure and entertainment.

箭身稳定性检测单元是指检测到箭靶上出现新箭后, 判断箭身颤动是否已 停止, 停止后才能检测新箭的位置, 以减少其他噪音的干扰。 具体过程与新箭 检测对比单元类似:  The arrow body stability detecting unit refers to detecting the position of the new arrow after stopping the new arrow on the target, and detecting the position of the new arrow after stopping, so as to reduce the interference of other noises. The specific process is similar to the new arrow detection comparison unit:
(1)按照靶盘定位中计算出的二值化阈值对上一幅图像和当前图像分别作 二值化, 并用当前二值化图像减去上一幅二值化图像, 得到差图像。  (1) Binarize the previous image and the current image according to the binarization threshold calculated in the target disk positioning, and subtract the previous binarized image from the current binarized image to obtain a difference image.
(2) 在差图像上作连通体分析, 根据宽高、 形状等判断箭身颤动是否已停 新箭位置检测单元  (2) Performing a connected body analysis on the difference image, judging whether the flutter is stopped according to the width, height, shape, etc. New arrow position detecting unit
新箭位置检测单元是指在新箭箭身稳定后, 检测新箭在箭靶上的位置, 并 结合靶盘定位得到的校准点信息计算新箭对应的分数。 具体过程如下- The new arrow position detecting unit refers to detecting the position of the new arrow on the target after the new arrow body is stabilized, and calculating the score corresponding to the new arrow by using the calibration point information obtained by the target disk positioning. The specific process is as follows -
(1)按照靶盘定位中计算出的二值化阈值对新箭出现前的那幅图像和当前 图像分别作二值化, 并用当前二值化图像减去新箭出现前的二值化图像, 得到 差图像。 (1) Binarize the image before the occurrence of the new arrow and the current image according to the binarization threshold calculated in the target disk positioning, and subtract the binarized image before the appearance of the new arrow with the current binarized image. , get the difference image.
(2) 在差图像上找直线, 以此作为候选箭身。 由于新箭可能会造成原有箭 的箭身位置发生变化, 因此可能会多找出一些错误的箭身。  (2) Find a straight line on the difference image as a candidate arrow. Since the new arrow may cause the position of the arrow of the original arrow to change, it may be possible to find out more of the wrong arrow.
(3) ^^ ^^ M ^^ , 从而 、保留新箭的窬身 信息。 (3) ^^ ^^ M ^^ , thus keeping the body of the new arrow Information.
( 4) 结合靶盘定位得到的校准点信息, 对新箭箭身做透视变换, 得到新箭 在校正后箭靶图像上的位置, 从而计算出新箭对应的分数。  (4) Combine the calibration point information obtained by the target disk positioning, and make a perspective transformation on the new arrow body to obtain the position of the new arrow on the corrected arrow target image, thereby calculating the score corresponding to the new arrow.
本发明所述的射箭计分系统的图像采集器为摄像机, 图像采集器距离靶纸 的距离为 1200腿- 4000国, 图像采集器与靶心的角度为 0° 70° , 以保证所采 集到的图像清晰为准, 图像采集器所采集到的靶纸图像占整张图片的 1/2 2/3 时, 均可准确定位其所在靶环位置, 摄像机个数 摄像机个数越多, 采集的 定位图片越多, 定位数据越准确, 还可以从不同的角度来实时观察箭靶的任何 变化情况。 最经济实用选择两台, 如果其中一台出现故障, 另一台仍可以准确 无误地传输图像信息, 同时两台摄像机可以互为证明, 同时保存原始图像, 并 把每只箭的着靶位置记录于主控电脑主机数据库中, 以备选手査看分析等, 避 免人为做弊行为, 以保证比赛的公平性。  The image collector of the archery scoring system of the present invention is a camera, and the distance of the image collector from the target paper is 1200 legs - 4000 countries, and the angle between the image collector and the target is 0° 70° to ensure the collected The image is clearly defined. When the image of the target paper collected by the image collector occupies 1/2 2/3 of the whole picture, the position of the target ring can be accurately located. The more the number of cameras, the more the positioning is. The more images, the more accurate the positioning data, and the real-time observation of any changes in the target from different angles. The most economical and practical choice of two, if one of them fails, the other can still transmit the image information accurately, while the two cameras can prove each other, save the original image, and record the target position of each arrow. In the main control computer host database, check the analysis with alternative hands, etc., to avoid artificial cheating, to ensure the fairness of the game.
尽管已经示出和描述了本发明的实施例, 对于本领域的普通技术人员而言, 可以理解在不脱离本发明的原理和精神的情况下可以对这些实施例进行多种变 化、 修改、 替换和变型, 本发明的范围由所附权利要求及其等同限定。  While the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art The scope of the invention is defined by the appended claims and their equivalents.
