摘要
针对测量船光测设备的电视测量系统白天测星能力的不足 ,提出了一种新型的白天测星方法。该方法将光测设备测星的视频图像实时记录于计算机的硬盘 ,并根据判读存储于硬盘中星体图像的脱靶量 ,完成测量船的航向修正和动态标校。应用这种方法 ,可以提高光测设备白天测星的能力及测量船的总体测量精度 ,是一种准实时的。
A new method is provided to improve the ability in measuring star in daytime of TV measurement system in the measurement ship. By this method, video image of stars achieved by the TV measurement system on a optical measurement device can be recorded into a computer HD on real time, and the course modification of measurement ship and dynamic calibration can be realized through interpretation of stars video image which is saved in computer HD. The experimental results prove that this method may enhance the ability in measuring star in daytime of optical measurement device and whole measurement precision of measurement ship.
