摘要
目前市场上的立定跳远自动测距系统的种类较少,主要分为压力传感器测距、红外传感器测距。其所需传感器数量繁多,导致价格昂贵,且在测量过程中对仪器进行移动十分不便。针对该问题,设计了一种基于图像识别的立定跳远自动测距系统。该系统采用ARM微处理器为核心,外部接入射频识别、图像采集、报警提示等多个模块。以射频识别模块对用户身份进行检测,以高清高速自动对焦摄像头为图像采集设备,通过算法进行图像处理,实现成绩测量。实验表明:该立定跳远自动测距系统设计能够实现对用户立定跳远成绩的准确测量,系统稳定可靠,输出的成绩在理论误差范围之内。该自动测距系统具有低成本、低功耗的特点,能够应用在多种应用场合中。
At present,there are fewtypes of standing long jump automatic distance measuring systems on the market,which are mainly divided into pressure sensor ranging and infrared sensor ranging. The required large number of sensors results in high prices and it is inconvenient to move the instruments during the measurement process.To solve this problem,standing long jump automatic distance measuring system based on image recognition is designed. The system uses an ARMmicroprocessor as the core,and externally connects multiple modules such as radio frequency identification, image acquisition and alarm prompts. The radio frequency identification module is used to detect the user＇s identity,and the high-definition,high-speed autofocus camera is used as an image acquisition device. Image processing is performed by an algorithm to realize achievement measurement.The test shows that the design of the standing long jump automatic distance measuring system can achieve accurate measurement of the user＇s standing long jump,the system is stable and reliable,and the output is within the theoretical error range.The automatic ranging system has the characteristics of lowcost and lowpower consumption,and can be applied to various applications.
