摘要

视障人士可以使用智能手机导航应用程序到达目的地。然而，这些应用程序不提供检测移动物体的手段。本文介绍了一个Android应用程序，该应用程序使用智能手机的摄像头提供实时目标检测。照相机捕捉到的图像要进行数字处理。然后，该模型使用存储在移动设备中的卷积神经网络(CNN)从处理后的图像中预测物体。该模型为每个检测到的对象返回边界框。这些边界框用于计算物体到相机的距离。使用的模型是SSD MobileNet V1，该模型使用COCO (Common Objects in Context)数据集进行预训练。系统测试分为对象距离测试和精度测试。结果表明，对于8米以下的距离，计算距离的误差范围在5%以下。平均精密度为0.9393，平均召回率为0.4479。这意味着该系统可以通过智能手机中的嵌入式模型识别移动物体。

Mobile Surveillance Siren Against Moving Object as a Support System for Blind PeopleMobile Surveillance Siren Against Moving Object as a Support System for Blind People

Visually impaired people can use smartphone navigation applications to arrive at their destination. However, those applications do not provide the means to detect moving objects. This paper presents an Android application that uses the smartphone’s camera to provide real-time object detection. Images captured by the camera are to be processed digitally. The model then predicts objects from the processed image using a Convolutional Neural Network (CNN) stored in mobile devices. The model returns bounding boxes for each of the detected objects. These bounding boxes are used to calculate the distance from the object to the camera. The model used is SSD MobileNet V1, which is pre-trained using the Common Objects in Context (COCO) dataset. System testing is divided into object distance and accuracy testing. Results show that the margin of error for calculating distance is below 5% for distances under 8 meters. The mean average precision is 0.9393, while the mean average recall is 0.4479. It means that the system can recognize moving objects through the embedded model in a smartphone.
