El experto de Semalt dice cómo extraer imágenes de un sitio web

Hoy en día, la web se ha convertido indudablemente en la referencia más extensa tanto de datos estructurados. Los sitios web dinámicos muestran datos en diferentes formatos, lo que hace que sea un poco difícil extraer datos de estos tipos de sitios al mismo tiempo. Es por eso que necesita navegar y tomar el software de raspado para recuperar los datos del objetivo en tiempo real.

El raspado web se usa para extraer imágenes, textos y archivos de sitios web a una sola hoja de cálculo o base de datos. Hoy en día, las variedades de herramientas de raspado de imágenes son gratuitas en toda la web. En esta publicación, aprenderá cómo extraer imágenes de un sitio web utilizando diferentes raspadores de imágenes de navegación y captura.

Hay algunos raspadores de imagen populares a tener en cuenta:

Web Scraper

Web Scraper es un complemento de Google Chrome de alta calidad utilizado para extraer imágenes de sitios web modernos. Con el raspador web, puede crear un plan que navegará y extraerá imágenes del sitio web de destino.

A diferencia de otros raspadores de imágenes que extraen imágenes solo de HTML, el raspador web también raspa los sitios de carga de JavaScript. Después de rastrear un sitio, puede descargar las imágenes en formato CSV o guardar las imágenes en CouchDB. Tenga en cuenta que CouchDB se utiliza comúnmente para proyectos avanzados de raspado de imágenes.

Raspador de imágenes Owidig

Owidig es una extensión de Google Chrome que se compone de funciones integradas preensambladas para facilitar la experiencia de raspado de imágenes. Puede usar el raspador de imágenes Owidig para extraer imágenes vinculadas a directorios de archivos a través de un Identificador Uniforme de Recursos (URI) en el HTML y pegar el sitio de destino en su complemento. Sin embargo, si las imágenes están vinculadas a una fuente externa usando Python o JavaScript, debe utilizar la dirección de origen ideal.

Herramienta de raspado Octoparse

Octoparse es un raspador de imagen "hágalo usted mismo" que es altamente recomendado tanto para usuarios inexpertos como experimentados. Con Octoparse, puede extraer URL de imágenes de destino y guardarlas con su pestaña de extensiones de Google Chrome.

Instale Octoparse en su máquina y deje que la rasqueta haga el resto de la tarea de raspado de la imagen por usted. En la mayoría de los casos, los raspadores web utilizan Octoparse para descargar y extraer una gran cantidad de imágenes de sitios web. En la industria del marketing actual, el web scraping se ha convertido en una tarea única que puede ser ejecutada de manera eficiente incluso por los principiantes.

OutWit Hub

Es un raspador de imágenes simple que proporciona un raspado web eficiente sin requerir conocimientos técnicos avanzados o habilidades de programación. OutWit Hub incorpora fácilmente un motor de raspado, extractores de datos y un navegador web. Este software disecciona la página web objetivo para raspar las imágenes disponibles automáticamente.

A diferencia de otros raspadores de imágenes, OutWit Hub carga imágenes en lugar de simplemente copiar enlaces. Si actualmente está buscando un software de exploración de imagen y navegación, OutWit Hub es la mejor herramienta para buscar.

Si está utilizando un servicio de raspado o un lenguaje de programación, busque etiquetas de imagen y extraiga los atributos de cada objeto identificado. Recupere las URL de su imagen de destino mediante la solicitud HTTP y guarde los resultados en su sistema de archivos denominado como "archivo de imagen". Para proyectos a pequeña escala, puede identificar su imagen objetivo, haga clic derecho en la imagen y toque el botón "Guardar" para descargar y guardar la imagen como un archivo local.
