Problems solved by technology

[0003] The existing low-light image distortion correction uses a square target for image correction, and the infrared image distortion correction uses a goniometric method combining a turntable and a point target for correction. The distortion correction of low-light and infrared sensors needs to be carried out separately, and infrared low-light Correction of dual-channel images in the same field of view
Due to the difference in distortion correction coefficients after infrared low-light dual-channel image fusion, the fusion effect is affected

Embodiment Construction

[0019] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0020] The invention relates to an infrared low-light dual-channel image fusion distortion correction target plate, such as figure 1 As shown, it consists of a black target grid, a white target grid, a temperature control device, and a fixed bracket. It is used to test and correct the distortion caused by a large field of view when performing infrared low-light dual-channel scene fusion. The shape of the target plate is alternating black and white grids, with 9 target grids in the horizontal direction and 7 target grids in the vertical direction. The black target grids can be heated, and the white target grids cannot be heated. The temperature device controls the temperature difference between the black and white target grids, so as to realize the contrast image of black and white changes presented by the infrared detector observation. At the same time, when the...

Abstract

The invention relates to an infrared low-light-level dual-channel image fusion distortion correction target plate, Black target, white target, A temperature control device and a fixing bracket, the shape of the target plate is black-and-white grid alternating, The black target can be heated and the white target cannot be heated. Temperature measuring elements are installed on both the black and white targets. The temperature difference between the black and white targets is controlled by temperature control device, so that the black and white contrast images presented by infrared detectors canbe obtained. At that same time, the contrast image of black and white change can also be present due to the different colors of the black and white target when the low-light-level detector observe. After infrared and low-light-level dual-channel image fusion, the distortion correction of infrared low-light-level dual-channel image fusion can be realized by analyzing the target mismatch and correcting it.

Description

technical field [0001] The invention belongs to the technical field of photoelectric testing, and in particular relates to an infrared low-light dual-channel image fusion distortion correction target plate. Background technique [0002] The target board can quickly and uniformly correct the distortion inconsistency after fusion of infrared low-light dual-channel images of optoelectronic products, and avoid image fusion errors caused by inconsistency in infrared low-light image distortion. [0003] The existing low-light image distortion correction uses a square target for image correction, and the infrared image distortion correction uses a goniometric method combining a turntable and a point target for correction. The distortion correction of low-light and infrared sensors needs to be carried out separately, and infrared low-light Dual-channel images are corrected under the same field of view. Due to the difference in distortion correction coefficients after fusion of infr...
