Abstract

The axis consistency of multiple optical sensors is an important guarantee to ensure the normal operation for photoelectric task equipment of weapon system. The presented status quo of methods and equipment are analyzed for measuring the consistency of large spacing axes. An axis consistency detection method is proposed based on non-cooperative target image processing technology. Specifically, it is available to select scenes with typical characteristics in the far field as non-cooperative targets. Then, the axis consistency detection results are obtained by comparing the position differences of non-cooperative targets in different image spaces. Compared with other detection methods and equipment, our method avoids many disadvantages including huge volume, heavy weight and the limited operation environment. Furthermore, it is especially suitable for axis detection of in field and on-line to large-distance photoelectric equipment, which shows a bright application prospect.

Overview

Overview

Overview: The axes consistency among different task modules in the platform photoelectric equipment and the axes consistency between the platform photoelectric equipment and gun barrel axis affect directly the operational effectiveness of weapon system. As a result, it is particularly urgent to carry out the research and equipment development of optical axis consistency detection technology of the platform photoelectric equipment under in field and on-line conditions. Obviously, large spacing, wide spectrum and multi-axis are the main characteristics of axis consistency detection for platform photoelectric equipment.
The presented status quo of methods and equipment are analyzed for measuring the consistency of large spacing axes. According to the above analysis, the large-spacing optical axis consistency measuring method and equipment have their own advantages and disadvantages respectively in terms of measuring range, measuring accuracy, portability and price. For example, the projection target plate measuring method is limited clearly by site and environmental conditions. Meanwhile, the collimator measuring method is used mostly in laboratory conditions. Furthermore, the cost of the inertial measuring method and the photogrammetry measuring method is high although they can meet the large-distance axis detection needs. In contrast, the intersecting target calibration method is simple in structure and portable in operation in spite of requiring a long visual distance. The applicability of axis detection equipment in field and on-line will be greatly improved if the visual distance can be shortened effectively on the premise of ensuring the measurement accuracy.
Therefore, an axis consistency detection method is proposed based on non-cooperative target image processing technology. Specifically, it is available to select scenes with typical characteristics in the far field as non-cooperative targets. Then, the axis consistency detection results are obtained by comparing the position differences of non-cooperative targets in different image spaces. The experimental results and error analysis show that the method can meet the requirements of large spacing axis consistency detection. The average value of angle measurement error is 15.96″ and the standard deviation is 2.80″ respectively for two parallel visible light axes. Meanwhile, it is available to select the visibility distance of about 100 m as the observation distance between the object to the measured target can meet the detection accuracy requirements of most photoelectric equipment. Compared with other detection methods and equipment, the method avoids many disadvantages including huge volume, heavy weight and limited operation environment. It is especially suitable for axis detection of in field and on-line to large-distance photoelectric equipment, which shows a bright application prospect.
