1. Model Conversation

Before the conversion, it is necessary to first set up the environment for model conversion. Please refer to the following document to prepare the environment:NN Model Conversion

...

We can get the nb file and a c file for NN graph setup information.

...

1.3. Demo Video

This video is the demo for yolov8s-detection int16 quantize.

2.2. Program Compile

When compiling NN-related applications, SDK's headers and libraries must be included.

3. Example flow of the program build and run

Unzipped

then placed them in ~/c3v/Models/yolov8s-detection/wksp/yolov8s_uint8_nbg_unify Folder. The brief folder of the project is like this:

3.2. cross-compile in Linux

If you want to build the project in host Linux, please modify these contents of Makefile:

Code Block
BIN=yolov8s-detection-uint8
# 1.cross compile
NN_SDK_DIR=Path to NN SDK directory
TOOLCHAIN=Path to toolchain directory
CROSS_COMPILE=$(TOOLCHAIN)/aarch64-none-linux-gnu-
CC=$(CROSS_COMPILE)gcc
CXX=$(CROSS_COMPILE)g++

you need to set the right path of NN_SDK_DIR and TOOLCHAIN

NN_SDK_DIR: The path to NPU SDK

TOOLCHAIN: The cross-compile toolchain path. which format may be like this:

Code Block
TOOLCHAIN=/pub/toolchain/crossgcc/gcc-arm-9.2-2019.12-x86_64-aarch64-none-linux-gnu/bin

then using make to compile the project.

Code Block
make

Copy the application, network_binary.nb file and related libraries into C3V Linux and run:

The param1 is the nb file that converts from the acuity toolkit.

The param2 is the image that is for detection. Please prepare the image file which format is jpg and the pixel size is 640 * 640.

Code Block
./yolov8s-detection-uint8 ./network_binary.nb ./input299)]
obj: L: 2 P:0.33, [(534, 294) - (74, 64)]
obj: L: 0 P:0.26, [(539, 264) - (99, 349)]

3.2. ImageWriter Tool

If you want to show the detection results in an image, we suggest using ImageWriter tools.

Please download

View file
nameimageWriter.zip
and compile it in c3v:

Code Block
cd imageWriter
make -j

Then you can run the imageWriter application directly on c3v:

Param1 is the image which is the same as yolov8s-detection-uint8 param2. The yolov8s-detection-uint8 is the application that is built in step 3.1. build in c3v.

Param2 is the file detect_results.raw which was generated after the program yolov8s-detection-uint8 runs.

Param3 is the output name, which format is jpg.

Code Block
./imageWriter ./input.jpg ./detect_results.raw ./output.jpg

The result is like this:
