Face search system? Baidu AI interface and Golang are jointly created!

With the development of artificial intelligence, face recognition technology is becoming more and more widely used in life and work. Among them, the face search system is a very popular application scenario. This article will introduce how to use Baidu AI interface and Golang programming language to build an efficient face search system.

First, we need to register an account on Baidu AI platform and create an application. After completing the registration, we can get an API Key and Secret Key, which will be used to call the Baidu AI interface.

Next, we need to download Golang’s open source project “baidu-aip-go-sdk”, which is an SDK that can interact with Baidu AI interface.

package main

import (
    "fmt"
    "github.com/chenqinghe/baidu-ai-go-sdk/vision/face"
    "os"
)

const (
    APP_ID     = "YOUR_APP_ID"
    API_KEY    = "YOUR_API_KEY"
    SECRET_KEY = "YOUR_SECRET_KEY"
)

func main() {
    client := face.NewClient(API_KEY, SECRET_KEY)

    imageFile, err := os.Open("test.jpg")
    if err != nil {
        fmt.Println("图片打开失败:", err)
        return
    }
    defer imageFile.Close()

    image, err := ioutil.ReadAll(imageFile)
    if err != nil {
        fmt.Println("读取图片失败:", err)
        return
    }

    faces, err := client.Search(image, nil)
    if err != nil {
        fmt.Println("人脸搜索失败:", err)
        return
    }

    if len(faces) == 0 {
        fmt.Println("未找到匹配的人脸")
        return
    }

    fmt.Println("找到匹配的人脸:")
    for _, face := range faces {
        fmt.Println(face.FaceToken)
    }
}

In the above code, we first imported the face recognition package of "baidu-aip-go-sdk" and set the API Key and Secret Key we obtained by registering on the Baidu AI platform. In the main function, we create a client object and open a test image.

Next, we read the binary data of the image and called the "Search" method through the client object to perform face search. If the search is successful, we will output the FaceToken of all found faces in the console.

In the code, we use some basic operations of the Golang language, such as error handling, file operations, etc. Maybe some readers who are not familiar with Golang will be a little confused about the above code, but don't worry, the syntax features of most programming languages ​​are similar, and you only need a little study to understand them.

In addition to face search, Baidu AI interface also supports other functions, such as face comparison, face detection and face registration. If we are interested in these functions, we only need to make the corresponding calls in the code.

Through the above introduction, we can see that it is very simple and convenient to use Baidu AI interface combined with Golang programming language to build a face search system. Today, facial recognition technology has penetrated into every aspect of our daily lives, such as security monitoring, facial payment, etc. I believe that in the future, face search systems will be more widely used and developed.
