Anota imágenes con la función ML.ANNOTATE_IMAGE

En este documento, se describe cómo usar la función ML.ANNOTATE_IMAGE con un modelo remoto para anotar imágenes a partir de una tabla de objetos.

Roles obligatorios

Para crear un modelo remoto y anotar imágenes, necesitas los siguientes roles de Identity and Access Management (IAM) a nivel del proyecto:

• Crear y usar conjuntos de datos, tablas y modelos de BigQuery: Editor de datos de BigQuery (roles/bigquery.dataEditor)

• Crear, delegar y usar conexiones de BigQuery: Administrador de conexiones de BigQuery (roles/bigquery.connectionsAdmin)

  Si no tienes configurada una conexión predeterminada, puedes crear y establecer una como parte de la ejecución de la instrucción CREATE MODEL. Para ello, debes tener el rol de administrador de BigQuery (roles/bigquery.admin) en tu proyecto. Para obtener más información, consulta Cómo configurar la conexión predeterminada.

• Otorga permisos a la cuenta de servicio de la conexión: Administrador de IAM del proyecto (roles/resourcemanager.projectIamAdmin)

• Crear trabajos de BigQuery: Usuario de trabajo de BigQuery (roles/bigquery.jobUser)

Estos roles predefinidos contienen los permisos necesarios para realizar las tareas de este documento. Para ver los permisos exactos que son necesarios, expande la sección Permisos necesarios:

También puedes obtener estos permisos con roles personalizados o con otros roles predefinidos.

Antes de comenzar

Accede a tu cuenta de Google Cloud . Si eres nuevo en Google Cloud, crea una cuenta para evaluar el rendimiento de nuestros productos en situaciones reales. Los clientes nuevos también obtienen $300 en créditos gratuitos para ejecutar, probar y, además, implementar cargas de trabajo.

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

Verify that billing is enabled for your Google Cloud project.

Enable the BigQuery, BigQuery Connection API, and Cloud Vision API APIs.

Roles required to enable APIs

To enable APIs, you need the serviceusage.services.enable permission. If you created the project, then you likely already have this permission through the Owner role (roles/owner). Otherwise, you can get this permission through the Service Usage Admin role (roles/serviceusage.serviceUsageAdmin). Learn how to grant roles.

Crea un conjunto de datos

Crea un conjunto de datos de BigQuery que contenga tus recursos:

Crear una conexión

Crea una conexión de recurso de Cloud y obtén la cuenta de servicio de la conexión. Crea la conexión en la misma ubicación que el conjunto de datos que creaste en el paso anterior.

Puedes omitir este paso si tienes configurada una conexión predeterminada o si tienes el rol de administrador de BigQuery.
