FastDeploy簡介

FastDeploy是一款全場景、易用靈活、極致高效的AI推理部署工具， 支持云邊端部署。提供超過 160+Text，Vision， Speech和跨模態(tài)模型開箱即用的部署體驗，并實現(xiàn)端到端的推理性能優(yōu)化。包括 物體檢測、字符識別（OCR）、人臉、人像扣圖、多目標(biāo)跟蹤系統(tǒng)、NLP、Stable Difussion文圖生成、TTS 等幾十種任務(wù)場景，滿足開發(fā)者多場景、多硬件、多平臺的產(chǎn)業(yè)部署需求。

準(zhǔn)備工作本文的FastDeploy適配過程需要準(zhǔn)備如下：·凌蒙派-RK3568開發(fā)板（即需FastDeploy適配的設(shè)備終端）·Ubuntu（即建立于虛擬機的Linux編譯環(huán)境）目前，我已將FastDeploy適配到凌蒙派開發(fā)板上，可用于目標(biāo)檢測、人臉檢測、人臉識別、人臉對齊、圖像分割、OCR等領(lǐng)域，這將大大提高凌蒙派開發(fā)板在邊緣計算方面的能力。

編譯步驟

我們推薦在PC上進行交叉編譯（即在Ubuntu進行交叉編譯）。

git clone https://github.com/PaddlePaddle/FastDeploy.gitcd FastDeploy# 如果您使用的是develop分支輸入以下命令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

目標(biāo)檢測模型速度表

為了方便大家選擇最適合自己的模型，我們選取了目前最流行的幾個模型，并整理了模型速度表供大家快速瀏覽。以下測試速度均為端到端的速度。

Demo演示

FastDeploy提供了統(tǒng)一的接口，可以快速的切換模型，這里以Yolov5為例子，展示如何在凌蒙派RK3568上進行目標(biāo)檢測。
