A simple guide to implement PHP docking with Baidu vehicle detection interface

With the increase in the number of vehicles and the seriousness of traffic congestion, more requirements have been put forward for the safety and management of vehicles. High requirements. Baidu vehicle detection interface can accurately identify the brand, model, color and other information of the vehicle, helping us manage vehicles quickly and effectively. This article will introduce how to use PHP to connect to Baidu vehicle detection interface and provide corresponding code examples.

1. Preparation

1. Register a Baidu Smart Cloud account and create an application. Log in to Baidu Smart Cloud official website (https://console.bce.baidu.com/ai/), register an account and log in, enter the console, click the "Create" button, and select "Smart Image - Vehicle Detection" to create an application.
2. Get API key. On the application management page, copy the "API Key" and "Secret Key" for later use.

2. Code Implementation
Please make sure you have installed the PHP environment and have basic PHP programming knowledge.

1. Create a PHP file named "baidu_vehicle_detection.php" and introduce related class files.

<?php

require_once 'AipImageClassify.php';

// 配置信息
const APP_ID = 'your app id';
const API_KEY = 'your api key';
const SECRET_KEY = 'your secret key';

$aipImage = new AipImageClassify(APP_ID, API_KEY, SECRET_KEY);

// 车辆检测接口函数
function vehicleDetection($image) {
    global $aipImage;
    $res = $aipImage->vehicleDetect($image);
    return $res['result'];
}

2. Implement vehicle detection interface.

$image = file_get_contents('path/to/your/image.jpg'); // 替换为你的图片路径

$result = vehicleDetection(base64_encode($image));

if (!empty($result)) {
    foreach ($result as $item) {
        echo '车辆类型：' . $item['name'] . '<br>';
        echo '颜色：' . $item['color'] . '<br>';
    }
} else {
    echo '未检测到车辆';
}

3. Code analysis

1. Introduce the "AipImageClassify.php" class file provided by Baidu AI open platform, and use the API Key and Secret obtained during the preparation work Key creates an AipImageClassify object.
2. Implement the vehicle detection interface, pass in the base64 encoding of the image, call the vehicleDetect method of Baidu vehicle detection API, and obtain the return results (vehicle brand, model, color and other information).
3. Display the vehicle type and color information based on the returned results.

4. Summary
This article introduces how to use PHP to connect to Baidu vehicle detection interface, and provides corresponding code examples. By using the Baidu vehicle detection interface, we can quickly and easily obtain vehicle-related information, helping us better manage and monitor vehicles. I hope this article can be helpful to everyone when using Baidu vehicle detection interface.
