基于凌蒙派开发板的FastDeploy适配-电子发烧友网

FastDeploy简介

FastDeploy是一款全场景、易用灵活、极致高效的AI推理部署工具，支持云边端部署。提供超过 160+Text，Vision， Speech和跨模态模型开箱即用的部署体验，并实现端到端的推理性能优化。包括物体检测、字符识别（OCR）、人脸、人像扣图、多目标跟踪系统、NLP、Stable Difussion文图生成、TTS 等几十种任务场景，满足开发者多场景、多硬件、多平台的产业部署需求。

准备工作本文的FastDeploy适配过程需要准备如下：·凌蒙派-RK3568开发板（即需FastDeploy适配的设备终端）·Ubuntu（即建立于虚拟机的Linux编译环境）目前，我已将FastDeploy适配到凌蒙派开发板上，可用于目标检测、人脸检测、人脸识别、人脸对齐、图像分割、OCR等领域，这将大大提高凌蒙派开发板在边缘计算方面的能力。

编译步骤

我们推荐在PC上进行交叉编译（即在Ubuntu进行交叉编译）。

git clone https://github.com/PaddlePaddle/FastDeploy.gitcd FastDeploy# 如果您使用的是develop分支输入以下命令git checkout developmkdir build && cd buildcmake .. -DCMAKE_C_COMPILER=/home/zbc/opt/gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-gcc \-DCMAKE_CXX_COMPILER=/home/zbc/opt/gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-g++ \-DCMAKE_TOOLCHAIN_FILE=./../cmake/toolchain.cmake \-DTARGET_ABI=arm64 \-DENABLE_ORT_BACKEND=OFF \-DENABLE_RKNPU2_BACKEND=ON \-DENABLE_VISION=ON \-DRKNN2_TARGET_SOC=RK356X \-DCMAKE_INSTALL_PREFIX=${PWD}/fastdeploy-0.0.0make -j12make install

目标检测模型速度表

为了方便大家选择最适合自己的模型，我们选取了目前最流行的几个模型，并整理了模型速度表供大家快速浏览。以下测试速度均为端到端的速度。

Demo演示

FastDeploy提供了统一的接口，可以快速的切换模型，这里以Yolov5为例子，展示如何在凌蒙派RK3568上进行目标检测。
