Description
Technical Field
The invention relates to the field of photoelectric detection, in particular to a multi-optical-axis consistency detection device of a photoelectric observation system, and further relates to a multi-optical-axis consistency detection method of the photoelectric observation system.
Background
The development of the photoelectric technology enables technologies such as visible light imaging, infrared thermal imaging, laser ranging and the like to be integrated in various types of photoelectric observation systems, can realize all-weather observation and ranging of targets all day long, and is widely applied to aspects such as national defense and security. However, for such a photoelectric observation system, it is objectively required that optical axes of components for visible light imaging, infrared thermal imaging, laser ranging, and the like are parallel to each other, i.e., multiple optical axes coincide. At present, the method for checking the consistency of multiple optical axes mainly comprises a parallel light tube method, a remote target method, a fixed target plate method and the like. Because of the difference of the working wave bands and mechanisms of visible light imaging and infrared thermal imaging, in order to meet the requirements of multiband working, the parallel light tube method currently mostly adopts off-axis reflection type parallel light tubes, a target plate or target paper is placed at the focus of the reflector, the photoelectric observation system is used for observing the aiming target plate and observing the relative position of a light spot formed on the target paper by the laser emitted by the laser ranging component to judge the consistency of the multiple optical axes, the detection method is mainly used for detection links in laboratories or in the production and debugging processes of products, has the characteristic of high detection precision, the defects of the detection device are that the price is high, the mobility is poor, the requirement on the detection environment is high, especially the relative position size of a plurality of optical axes of a detected photoelectric observation system is large, the caliber of a collimator is required to be correspondingly increased, the price of the detection device is greatly increased, and the detection device is not suitable for being developed under the field condition.
The remote target method is characterized in that under the conditions of good visibility and through vision, a remote target is selected, a visible light imaging component and an infrared thermal imaging component of a detected photoelectric observation system are used for observing the target, whether aiming points of self division centers in two images are consistent or not is observed, and whether two optical axes are consistent or not is further judged; for a laser ranging component in a detected photoelectric observation system, because the wavelength of laser is usually selected to be invisible wavelength and no observation field is available, the laser ranging component can only aim at the edge of a distant building through a partition in a visible light imaging or infrared thermal imaging image, the partition is tangent to the edge of the building in the upper, lower, left, right and other directions in sequence to perform ranging, and whether a laser ranging optical axis is consistent with a visible light imaging optical axis or an infrared thermal imaging optical axis is qualitatively judged according to ranging results. The method can only preliminarily judge whether the multiple optical axes are consistent or not, has low accuracy and has certain requirements on weather conditions and communication conditions.
The fixed target plate method is characterized in that visible light aiming points, infrared aiming points and laser ranging aiming points with relatively fixed positions are engraved on a target plate according to the relative position size of each optical axis of a detected photoelectric observation system, the fixed target plate is placed at a specified detection distance and sequentially passes through a visible light imaging assembly, an infrared thermal imaging assembly and a target lens equipped by the laser ranging assembly, the corresponding aiming points on the target plate are observed, and whether the corresponding aiming points can be aimed at simultaneously or not can be judged by observing the visible light imaging assembly, the self-division center in the image of the infrared thermal imaging assembly and the target lens division center of the laser ranging assembly, so that the consistency of multiple optical axes is detected and judged. The method has the disadvantages that due to different types of photoelectric observation systems, the relative position sizes of the optical axes are different, corresponding fixed target plates are required to be manufactured according to different types, the universal detection requirements of various types cannot be met, the laser ranging assembly is required to be provided with corresponding target mirrors, and otherwise, the detection of the laser optical axes cannot be carried out. In addition, whether the plane where the fixed target plate is located is basically perpendicular to the optical axis of the detected photoelectric observation system cannot be guaranteed, and certain influence is brought to the detection result.
