Abstract

The invention provides an apparatus and method for detecting the multiple optical axis consistency of a platform photoelectric instrument. The detection method comprises a detection host, a support mechanism and a data control processing system. A catadioptric optical collimating system,a multiband target plate and a target light source are adopted for determining the axial direction of each optical system, a CCD aiming assembly is utilized for acquiring the image of the same fixed target in a distant scene, afterwards, an image processing module performs pretreatment, coupling and optical axis parallelism calculatingon the image by using a template coupling method so that the position deviations of the same fixed target in different images is obtained and a detection result of the light axis consistency among the multiple optical systems can be further obtained. The apparatus is free from the axis distance restrictions among optical sensors, no cooperation targets and no calibration adjustment are needed, the detection precision is high, the volume is small, the weight is light, the operation is convenient, and the automation degree is high, therefore, the apparatus and method well satisfy the on-line rapid detection needs for detecting the multiple optical axis consistency of the platform photoelectric instrument in a field environment.
