i.MX8M+Myriad X+8MP摄像头：边缘AI开发套件实战解析边缘计算正在成为AI落地的重要路径，而高性能视觉推理是其中最具挑战的环节。通过专用VPU（如Myriad X）与嵌入式主控（如i.MX8M）协同，可实现低功耗下的实时目标检测与图像识别。其核心技术价值在于将深度学习模型部署在端侧，减少云端依赖，并借助OpenVINO工具链完成模型转换与优化。这一架构广泛应用于工业质检、智能安防、边缘终端等场景，能够以更高清分辨率捕捉细节，显著提升算法召回率。围绕一套集成8MP摄像头、i.MX8M与Myriad X的开发套件，深度解析其硬件架构、环境搭建、摄像头接入、模型部署阅读详情

我在pb 10.5中实验的结果是保存的图像名只取给定字符串的第一个字母，且没有后缀。这是怎么回事？
