Abstract
Telemetry image has the characteristics of intuitive image in the process of rocket flight. Through real-time acquisition of rocket flight video image, it can provide the working status of key nodes in the process of rocket flight, and provide intuitive decision-marking auxiliary information for commanders. This paper analyzes the design content of the image processing system of the space launch site from the aspects of image transmission mechanism, information flow, image data processing and image decoding, so as to provide technical basis for the image receiving, transmission and decoding process in the engineering practice of the image processing system.
Highlights
Image measurement technology has been widely used in aerospace domestically and abroad
Some crucial actions such as fairing separation, booster separation, interstage separation and satellite rocket separation can be observed by image measurement technology, and the working conditions of each cabin can be viewed in real time
The telemetry data frame received by the ground telemetry equipment is sent to the image processing system of arrow telemetry in the way of multicast, and the telemetry image data can be converted into video image through path selection and decoding for the decision-making and technical personnel to watch
Summary
Image measurement technology has been widely used in aerospace domestically and abroad. Multiple cameras are installed in each cabin and key parts of the rocket to synchronously collect the image data on the rocket in the space launch site [1]. Some crucial actions such as fairing separation, booster separation, interstage separation and satellite rocket separation can be observed by image measurement technology, and the working conditions of each cabin can be viewed in real time. The telemetry data frame received by the ground telemetry equipment is sent to the image processing system of arrow telemetry in the way of multicast, and the telemetry image data can be converted into video image through path selection and decoding for the decision-making and technical personnel to watch. The information flow of arrow remote image processing system is shown in the figure below
