Real-Time System of Photography Guiding Based on the Fusion Technology of Multimedia and Information Flow

This paper studies the real-time photography navigation system based on multimedia and information flow fusion technology, proposes an image retrieval scheme that integrates text, voice, image and other information features, and builds a new type of image based on voice recognition technology using MATLAB as the platform Retrieval system. Compared with text-based or content-based image retiieval systems, this system not only improves retrieval performance, but also makes human-computer interaction more convenient. Combining the two models before and after optimization, the theoretical and actual trajectory speeds of the moving body are simulated under the conditions of different speed ranges, correction amount $\delta$, camera and reflector distance hz.

I. Introduction

In recent years, digital high-speed cameras have played an important role in the testing of high-speed moving targets by virtue of their unique advantages such as simple deployment and non-contact [1] with the target. However, the moving target runs at an ultra-high speed of several kilometers per second. During transient processes such as burning and explosion [2], the excessive speed will cause serious smear. If the exposure time is compressed, the image brightness will be too low and difficult to recognize. Under complicated conditions such as smoke and fire, the shortcomings of the measurement [3] of parameters such as the transient speed, size and attitude angle of high-speed moving objects are obvious. Logistics is the physical movement of material data from supplier to demander, and physical logistics and information flow [4] are the two basic elements accompanying it. The logistics system connects manufacturers, transportation, distribution, and users. It has a large geographic span, a long time span, and a high degree of information dependence. It changes with changes [5] in supply and demand. Therefore, it is urgent that the information flow and physical logistics of the logistics system are synchronized and coordinated. Reflect the chain of actions from production [6], distribution, sales to users.
