Description

Technical Field

[0001] The utility model relates to the technical field of aerospace, and more particularly to a three-axis photoelectric pod. Background Art

[0002] An electro-optical pod is a specialized device that integrates multiple optoelectronic detection devices. It is typically suspended from the fuselage or under a wing. It can also be used in urban planning to provide high-definition, multi-angle observation of urban areas, acquiring detailed city data and data. Currently, electro-optical pods typically consist of a visible light camera, an infrared camera, a laser, a servo-stabilized platform, and an AI tracking processing module. The AI ​​tracking module processes image information from the visible light and infrared cameras to identify and track targets. Using a specific streaming algorithm, it outputs the video signal via a network port or SDI output port. A laser ranging module measures the distance to the target and calculates its position. The servo-stabilized platform enables X, Y, and Z-axis rotation and anti-shake of the image, enabling tracking of targets within the frame. However, image blur and artifacts such as vases still exist when outputting at low bit rates. Problems such as image jitter under high-frequency vibrations still exist, and target tracking can be easily lost. These issues significantly reduce the user experience of using the pod. To address this, we propose a three-axis electro-optical pod. Utility Model Content
