| 摘 要： | 介绍了一种新的测试方法：将四个矩形光幕以特定的角度分别放置在六面体的两个面和两个对角面上，当弹丸从光幕穿过，用测时仪记录弹丸穿过四个光幕的时刻，依据四个时刻值计算出弹丸穿过光幕的位置坐标．文中分析了四光幕交汇立靶测试测试系统的原理．提出一种用纸靶测量坐标值对测试系统的测量结果进行校准的方法，推导了校准公式．根据纸靶弹孔位置坐标，对原始公式进行修正，修正后的结果，减少了与纸靶比对的误差．

| Abstract: | A new bullet location measurement system is introduced.Four optical screens are installed respectively on two planes and diagonal planes of the hexahedron.When the bullet flys through the screens,the time of bullet impacting on screens is recorded.The impacting position can be calculated by using the data of times.The principle of four screens target measuring system for precise bullet location is presented.The result is calibrated by paper target sheet.The calibration formula is deduced.Comparing to the position of bullet hole in paper target sheet,the formula is modified to reduce the measurement error. |
