AI Technical Summary

Technical Problem

Existing technologies struggle to efficiently coordinate the visual information collected by algorithm models and hardware devices, making it difficult to achieve accurate distance measurement and focus parameter calculation for multiple objects. This restricts the fine scene perception of the vision system and the adaptive control of the optical system.

Method used

The system employs autofocus glasses based on YOLOv8n. Scene images are acquired through image acquisition devices, and object features are extracted after preprocessing. The ResNet-50 model is used for object classification, and the scene state is determined by combining indoor and outdoor feature object databases and neural network algorithms. The distance to the object at the focal point is calculated, and autofocus is achieved through hardware focusing control.

Benefits of technology

It enables the classification and detection of everyday objects with extremely low power consumption and computing power, quickly acquires environmental information, intelligently determines the objects that need to be focused, and adapts to the lens focal length needs of users in different scenarios to the greatest extent, thus achieving intelligent eye protection.

Abstract

本发明涉及自动调焦领域,公开了一种基于YOLOv8n的自动调焦眼镜焦距确定方法、系统、介质及设备,其包括:通过用户佩戴的眼镜上的图像采集设备获取场景图像,并将场景图像进行预处理后,提取场景图像中的物体特征,形成物体类别列表;根据物体类别列表,判断用户所处场景和状态是室内或室外,若为室外则不启动调焦继续采集场景图像,反之进行下一步;用户所处场景和状态为室内时,匹配一个确定的预设场景,以确定唯一的待对焦物体,计算视线焦点物体的距离,并判断是否需要变焦,若不需要变焦则不启动调焦继续采集场景图像,反之需要变焦,进行变焦处理。本发明解决了智能调焦眼镜如何通过用户所处环境判断用户对镜片的焦距需求的问题。
