How to integrate and use the human body recognition function of Baidu AI interface in a Java project

Abstract:
With the rapid development of artificial intelligence, human body recognition technology is in It has been widely used in various fields. This article will introduce how to integrate and use the human body recognition function of Baidu AI interface in a Java project. Through this function, functions such as human posture recognition, human body key point detection, and human body attribute analysis can be realized.

1. Introduction to Baidu AI Platform
Baidu AI (Baidu AI) is an artificial intelligence open platform launched by Baidu, which provides a rich set of AI technology interfaces, including face recognition, text recognition, and voice recognition. identification etc. Among them, the human body recognition interface provides functions such as human posture recognition, human body key point detection, and human body attribute analysis, and can be widely used in security monitoring, intelligent transportation and other fields.

2. Preparation
Before using Baidu AI interface, we need to register as a developer, create an application, and obtain the API Key and Secret Key. For specific operation procedures, please refer to Baidu AI official documentation.

3. Integrate Baidu AI SDK
Baidu AI officially provides a Java development SDK, which can easily integrate human body recognition functions in Java projects. We can introduce the SDK in the following ways:

1. Add the dependency of Baidu AI SDK in the pom.xml file:

<dependency>
    <groupId>com.baidu.aip</groupId>
    <artifactId>java-sdk</artifactId>
    <version>4.0.4</version>
</dependency>

2. Import the SDK related in the project code Class:

import com.baidu.aip.bodyanalysis.AipBodyAnalysis;

4. Initialize the AipBodyAnalysis object
Before using Baidu AI’s human body recognition function, we need to create and initialize an AipBodyAnalysis object. When creating an object, you need to pass in the API Key and Secret Key. The code to create the AipBodyAnalysis object is as follows:

AipBodyAnalysis client = new AipBodyAnalysis(APP_ID, API_KEY, SECRET_KEY);

Among them, APP_ID, API_KEY and SECRET_KEY are the relevant information obtained when you create an application on the Baidu AI platform.

5. Call the human body recognition interface
The human body recognition interface can be called through the AipBodyAnalysis object to implement related functions.

1. Human posture recognition
   Human posture recognition can identify the basic postures of the human body, such as standing, sitting, lying, etc.

// 读取图片的byte数组
byte[] image = Files.readAllBytes(Paths.get("path_to_image"));

// 调用人体姿势识别接口
JSONObject result = client.bodyPose(image, null);
System.out.println(result.toString(2));

2. Human key point detection
   Human key point detection can detect key points of the human body, such as the head, limbs, etc.

// 读取图片的byte数组
byte[] image = Files.readAllBytes(Paths.get("path_to_image"));

// 调用人体关键点检测接口
JSONObject result = client.bodyAnalysis(image, null);
System.out.println(result.toString(2));

3. Human body attribute analysis
   Human body attribute analysis can analyze the age, gender, emotion and other attributes of the human body.

// 读取图片的byte数组
byte[] image = Files.readAllBytes(Paths.get("path_to_image"));

// 调用人体属性分析接口
JSONObject result = client.bodyAttr(image, null);
System.out.println(result.toString(2));

6. Processing the returned results
After calling the human body recognition interface, a result in JSON format will be returned. We can process the data based on the returned results. For example, analyze the results of human gesture recognition:

// 解析人体姿势识别的结果
String pose = result.getJSONObject("person_info").getJSONArray("body_parts").getJSONObject(0).getString("pose");
System.out.println("人体姿势：" + pose);

7. Summary
This article introduces how to integrate and use the human body recognition function of Baidu AI interface in a Java project. By using Baidu AI's human recognition interface, we can realize functions such as human posture recognition, human body key point detection, and human body attribute analysis. I hope this article can help readers use Baidu AI to achieve human body recognition more easily. For more detailed API usage and parameter descriptions, please refer to Baidu AI official documentation.
