对超音速火箭橇试验的测试目标进行3向位移测量,由于音爆的影响和场地的限制,既不能进行人工跟踪拍摄,也没有合适的自动追踪设备,因此采用高速相机以接力拍摄的布局方式进行分段记录,并以前方交会的方法进行分段计算.通过精度估算,弹射救生座椅航向位移在650 m的范围内,其点位测试精度约为0.5 m.对于超音速火箭橇试验,形成了以拍摄频率高、测试范围大、分段拍摄与分段计算为特点的轨迹测试新技术.
3-way displacement measurement of the test target of the supersonic rocket sled test, because of the impact of sonic boom and site constraints, can not be manually tracking shots, there is no suitable automatic tracking device, so the use of high-speed camera relay shooting layout And the method of segment intersection was used to carry on the piecewise calculation.According to the precision estimation, the heading displacement of the ejection lifesaving seat is within the range of 650 m, the precision of its point test is about 0.5 m.For the supersonic rocket sled test, Formed a high-frequency shooting, testing a large range, sub-shooting and segment calculation is characterized by trajectory testing of new technologies.
