摘要:

介绍了大气相干长度仪测量软件的升级改进。该软件对原有图像处理方法进行了改进,提高了目标光斑的识别效率,将原有的半屏测量拓展为全屏测量,增强了系统的测量稳定性。同时,升级后的测量软件实现了大气相干长度仪在复杂环境下进行图像灰度和对比度的自动调节,仪器在执行跟踪测量任务时可以根据背景光变化实时调节目标识别算法的参数,进而能够对目标进行连续捕获。提出一种基于门限的算法实现了软件的自动跟踪功能,提高了仪器的自动化水平。

Abstract:

The metrical software of atmospheric coherence length instrument is upgraded. The image processing algorithm is ameliorated by the software and the efficiency target identification is improved. The area of image processing is doubled, and the stabilization of system is improved. Self-adaptation of the image brightness and contrast is realized in complex environment. Parameters of target identification algorithm can be adjusted by the atmospheric coherence length instrument real-time based on the changes of the brightness of background, so faculae can be captured continuously. The software’s auto tracking is realized based on the threshold algorithm, and the auto level of instrument is improved.

Key words: atmospheric coherence length, target identification, auto track, metrical software
