摘要
针对某机型记录的飞行参数存在较大误差的现象,基于特定图像细化和Hough变换对机载视频中航空仪表的读数进行图像自动判读。实验表明判读稳健有效,可用于飞参的对照分析和自动校正。
In order to revise the error caused by the flight parameter recording procedure of a given plane type, this paper discussed in details automatic interpretation technology of onboard instrument values, which utilized the instrument＇s image frame recorded in the onboard video and made some automatic interpretation based on the image thinning and Hough transform preproeessing. The experiment showed that the automatic interpretation method is robust and efficient, which can be used to compare and revise the flight parameter data automatically.
