摘要
传统方法无法有效描述激光测距仪电路故障的特点,难以准确实现激光测距仪电路故障分类和识别,为了提高激光测距仪电路故障的识别率,提出了基于模式识别的激光测距仪电路故障识别方法。首先分析当前激光测距仪电路故障识别的研究现状,并分析了激光测距仪电路故障识别的原理,然后获取激光测距仪电路故障识别数据,并提取激光测距仪电路故障识别特征,采用模式识别技术实现激光测距仪电路故障识别,最后进行了激光测距仪电路故障识别验证性测试实验。实验对比结果可知,本文方法的激光测距仪电路故障识别率高,可以有效保证激光测距仪正常工作,而且激光测距仪电路故障结果要优于其它方法。
Traditional methods cannot effectively describe the circuit fault characteristics of laser rangefinder,and it is difficult to accurately classify and identify the circuit fault of laser rangefinder. Therefore,the circuit fault identification of laser rangefinder based on pattern recognition is proposed to improve the identification efficiency. Firstly,the current research status of circuit fault identification of laser rangefinder is analyzed,and the principle of circuit fault identification of laser rangefinder is analyzed. Then the circuit fault identification data of laser rangefinder is obtained,and the circuit fault identification characteristics of laser rangefinder are extracted. The circuit fault identification of laser rangefinder is realized based on pattern recognition technology. Finally,the verification test of circuit fault identification of laser rangefinder is carried out. The experimental results show that the circuit faults recongnition rate of the laser rangefinder are high,which can effectively ensure the normal operation of the laser rangefinder,and the circuit fault results of the laser rangefinder are better than other methods.
