Cloud Vision API를 사용하여 이미지에서 라벨 인식

이 빠른 시작에서는 다음 방법을 보여줍니다.

  • Cloud Storage 버킷을 만듭니다.
  • Cloud Storage에 이미지를 업로드하고 파일을 공개적으로 액세스할 수 있도록 설정합니다.
  • 해당 이미지로 Vision API에 요청 수행

이 단계를 완료하는 데 5분 정도 걸립니다. Cloud Storage에 무료로 최대 5GB의 데이터를 저장하고, Vision API에 무료로 매달 최대 1,000건의 기능 요청을 보낼 수 있습니다.

시작하기 전에

아직 설정하지 않았다면 다음 안내에 따라 프로젝트를 설정하고 Cloud Storage 버킷을 만듭니다.

프로젝트 설정

  1. Sign in to your Google Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.

  2. In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

    Roles required to select or create a project

    • Select a project: Selecting a project doesn't require a specific IAM role—you can select any project that you've been granted a role on.
    • Create a project: To create a project, you need the Project Creator role (roles/resourcemanager.projectCreator), which contains the resourcemanager.projects.create permission. Learn how to grant roles.

    Go to project selector

  3. Verify that billing is enabled for your Google Cloud project.

  4. Enable the Cloud Vision API.

    Roles required to enable APIs

    To enable APIs, you need the Service Usage Admin IAM role (roles/serviceusage.serviceUsageAdmin), which contains the serviceusage.services.enable permission. Learn how to grant roles.

    Enable the API

    필요한 역할

    1. Make sure that you have the following role or roles on the project: Storage Admin (roles/storage.admin)

      Check for the roles

      1. In the Google Cloud console, go to the IAM page.

        Go to IAM
      2. Select the project.

      3. In the Principal column, find all rows that identify you or a group that you're included in. To learn which groups you're included in, contact your administrator.

      4. For all rows that specify or include you, check the Role column to see whether the list of roles includes the required roles.

      Grant the roles

      1. In the Google Cloud console, go to the IAM page.

        IAM으로 이동
      2. 프로젝트를 선택합니다.
      3. 액세스 권한 부여를 클릭합니다.

      4. 새 주 구성원 필드에 사용자 식별자를 입력합니다. 일반적으로 Google 계정의 이메일 주소입니다.

      5. 역할 선택 목록에서 역할을 선택합니다.
      6. 역할을 추가로 부여하려면 다른 역할 추가를 클릭하고 각 역할을 추가합니다.
      7. 저장을 클릭합니다.

      Cloud Storage 버킷 생성

      1. In the Google Cloud console, go to the Cloud Storage Buckets page.

        Go to Buckets

      2. Click Create.
      3. On the Create a bucket page, enter your bucket information. To go to the next step, click Continue.
        1. For Name your bucket, enter a unique bucket name. Don't include sensitive information in the bucket name, because the bucket namespace is global and publicly visible.
        2. In the Choose where to store your data section, do the following:
          1. Select a Location type.
          2. Choose a location where your bucket's data is permanently stored from the Location type drop-down menu.
