主体识别示例
本章节对主体识别AK/SK方式使用SDK进行示例说明。
- 主体识别示例代码只需将AK/SK信息替换为实际AK/SK,代码中可以使用ImageMainObjectDetectionReq中的withUrl或withImage方法配置图像信息(image和url参数二选一),示例中以url为例,配置完成后运行即可。
- endpoint是华为云各服务应用区域和各服务的终端节点,详情请查看地区和终端节点 。
- 主体识别调用示例代码如下:
package com.huaweicloud.sdk.test; import com.huaweicloud.sdk.core.auth.ICredential; import com.huaweicloud.sdk.core.auth.BasicCredentials; import com.huaweicloud.sdk.core.exception.ConnectionException; import com.huaweicloud.sdk.core.exception.RequestTimeoutException; import com.huaweicloud.sdk.core.exception.ServiceResponseException; import com.huaweicloud.sdk.image.v2.region.ImageRegion; import com.huaweicloud.sdk.image.v2.*; import com.huaweicloud.sdk.image.v2.model.*; public class RunImageMainObjectDetectionSolution { public static void main(String[] args) { // 认证用的ak和sk硬编码到代码中或者明文存储都有很大的安全风险,建议在配置文件或者环境变量中密文存放,使用时解密,确保安全 // 本示例以ak和sk保存在环境变量中来实现身份验证为例,运行本示例前请先在本地环境中设置环境变量HUAWEICLOUD_SDK_AK和HUAWEICLOUD_SDK_SK String ak = System.getenv("HUAWEICLOUD_SDK_AK"); String sk = System.getenv("HUAWEICLOUD_SDK_SK"); ICredential auth = new BasicCredentials() .withAk(ak) .withSk(sk); ImageClient client = ImageClient.newBuilder() .withCredential(auth) .withRegion(ImageRegion.valueOf("cn-north-4")) //此处替换为您开通服务的区域,详情请查看地区和终端节点. .build(); RunImageMainObjectDetectionRequest request = new RunImageMainObjectDetectionRequest(); ImageMainObjectDetectionReq body = new ImageMainObjectDetectionReq(); body.withThreshold(30f); body.withUrl("https://XXX.jpg"); //替换为公网可以访问的图片地址 request.withBody(body); try { RunImageMainObjectDetectionResponse response = client.runImageMainObjectDetection(request); System.out.println(response.toString()); } catch (ConnectionException e) { e.printStackTrace(); } catch (RequestTimeoutException e) { e.printStackTrace(); } catch (ServiceResponseException e) { e.printStackTrace(); System.out.println(e.getHttpStatusCode()); System.out.println(e.getErrorCode()); System.out.println(e.getErrorMsg()); } } }
- 执行示例代码文件,控制台输出主体识别结果即表示程序执行成功。相关参数说明请参考主体识别API。
RunImageMainObjectDetectionResponse { result: [class ImageMainObjectDetectionInstance { label: bounding_box location: {height=327.77, top_left_x=3.7, top_left_y=1.72, width=463.03} confidence: 95.73 }, class ImageMainObjectDetectionInstance { label: main_object_box location: {height=328.35, top_left_x=3.22, top_left_y=1.5, width=456.63} confidence: 88.35 }] }
