The on-line detection of a certain photoelectric tracking system was realized through the computer simulation platform,however,the simulation platform is large in volume,inconvenient in carrying and complex in installation.In order to solve the problem of using in field,a portable photoelectric tracking system on-line detection device was designed and implemented.The device adopts the ARM embedded platform based on WinCE operating system and divides the working state detection into one system-level module and multiple component-level modules,which can conduct testing through module according to actual needs,thereby the CPU load and detecting device consumption can be reduces.Actual verification show that,the device can realize real-time on-line detection of the detailed state of photoelectric tracking system and accurately locate the fault site to achieve the purpose of quickly repairing the fault.

Aiming at solving problem of weak small target missing during dimension reduction and fusion of hyperspectral data, hyperspectral data fusion method for weak small target is studied in this paper.Class pixel matrix is produced by similarity measures, dimension reduction projection matrix is calculated by principal component transforming class pixel matrix, and dimension reduction data is obtained by dimension reduction projection matrix projecting the original spectral data.False-color result image is produced by RGB color space transforming from reduction data.Fusion performance of improved method is verified by hyperspectral data of weak small target and underwater fish group.Experiments show that similarity classification fusion method can not only get one false color image from high dimension hyperspectral data, but also avoid missing weak small targets from background, which enhances abilities of detection and identification, and has a strong application prospects.
