# 颜色检测 [[English]](./README.md)
本项目为颜色检测接口的示例。颜色检测接口的输入图片为一张带有不同色块的静态图片。
输出是录入颜色、检测颜色、分割颜色， 删除颜色等接口功能的运行结果，显示在终端中。
项目所在文件夹结构如下：
```shell
color_detect/
├── CMakeLists.txt
├── rgby.jpg
├── main
│ ├── app_main.cpp
│ ├── CMakeLists.txt
│ └── image.hpp
├── partitions.csv
└── README.md
└── README_cn.md
```
## 运行示例
1. 打开终端，进入颜色检测示例所在文件夹 esp-dl/examples/color_detect：
```shell
cd ~/esp-dl/examples/color_detect
```
2. 设定目标芯片：
```shell
idf.py set-target [SoC]
```
将 [SoC] 替换为您的目标芯片，如 esp32、esp32s2、esp32s3。
由于 ESP32-S3 芯片在 AI 应用上的运行速度远快于其他芯片，我们更推荐您使用 ESP32-S3 芯片。
3. 烧录程序，运行 IDF 监视器获取各功能的运行结果：
```shell
idf.py flash monitor
... ...
