AI Technical Summary

Problems solved by technology

However, in practical applications, it is necessary to capture the target at a long distance and obtain relevant information of the target, which will result in a small imaging area of ​​the long-distance target, lack of obvious structural features and brightness features, and the AI ​​​​algorithm cannot accurately identify it; at the same time, the image in a complex background The signal-to-noise ratio is low, and small targets with low contrast are easily overwhelmed by system noise or complex backgrounds

Abstract

The present invention relates to the technical field of imaging and image processing, and in particular to an ARM-based clear imaging system and method for long-distance targets. The imaging system includes an image sensor, a data processing chip ARM, a lens assembly, and an AI algorithm module. The image sensor collects The image data is processed and judged by the data processing chip ARM. When it is judged that there is a target object in the image, the data processing chip ARM will issue a zoom command to the lens assembly and zoom to obtain the target picture, and then perform After processing such as correction and encoding, it is sent to the AI ​​algorithm module for recognition. The present invention can perform rapid zooming and zooming response, has the characteristics of long recognition distance, stable and clear image, fast target recognition, accurate target recognition, etc., and provides good picture data for accurate recognition of long-distance targets.

Description

technical field [0001] The invention relates to the technical field of long-distance imaging and image processing, in particular to an ARM-based clear imaging system and method for a long-distance target. Background technique [0002] With modern information becoming increasingly diversified and intelligent, automatic identification and tracking of air-to-ground long-distance small targets is of great significance in today's social defense field. It is also an important research field in computer vision and can be applied to long-distance surveillance such as Search and tracking systems; and the current application of AI algorithms is becoming more and more common. However, in practical applications, it is necessary to capture the target at a long distance and obtain relevant information of the target, which will result in a small imaging area of ​​the long-distance target, lack of obvious structural features and brightness features, and the AI ​​​​algorithm cannot accuratel...
