Image labeling and classification
Cloud Vision API assigns generalized labels to images and returns a description, confidence score, and topicality rating for each label.

Vision AI is Google Cloud’s set of computer-vision tools for extracting information from images, documents, and videos. It helps developers automate visual analysis with pretrained APIs, document-understanding services, video analysis, and multimodal AI options.
什么是 Vision AI？
Vision AI is Google Cloud’s portfolio of computer-vision and visual AI services. It helps applications interpret images, scanned documents, and videos by applying pretrained models and returning outputs such as labels, extracted text, detected objects, landmarks, faces, and content-safety signals.
The portfolio covers several related workloads. Cloud Vision API provides ready-to-use image features through REST and RPC interfaces; Document AI focuses on extracting text and structured information from documents; and Video Intelligence API analyzes stored or streaming video. Google Cloud also presents multimodal and generative options for image descriptions, classification, search, image generation, editing, and embeddings.
Use Vision AI when a product or workflow needs automated visual analysis rather than manual inspection. The right service depends on the input and desired result: basic image detection, document understanding, video analysis, or generative and multimodal processing.
Vision AI 能做什么？
OCR for images and documents
Text Detection recognizes text in images, while Document Text Detection is optimized for dense text, handwriting, and PDF or TIFF files. Responses can include text annotations, bounding boxes, detected languages, and document structure.
Object, face, landmark, and logo detection
Pretrained image features identify localized objects, faces, landmarks, and logos, with outputs such as coordinates, confidence scores, or bounding polygons where applicable.
Image properties and safety analysis
The API can return dominant image colors and apply SafeSearch explicit-content detection, supporting metadata and content-moderation workflows.
Document understanding
Document AI combines computer vision, natural-language processing, and machine learning to classify documents and extract text, entities, and structured data from scanned material.
Video and multimodal analysis
Video Intelligence API supports object tracking, scene understanding, activity recognition, face analysis, and text recognition in video. Other Google Cloud offerings provide visual captioning, multimodal embeddings, image generation, and image editing.
使用场景
“Image-processing pipelines”
Add automated labels, detected objects, image properties, or safety signals to incoming images before they are indexed, reviewed, or passed to another application step.
“Scanned-document workflows”
Use document-oriented OCR and Document AI to turn PDFs, TIFF files, and document images into searchable text and structured information for downstream processing.
“Searchable video archives”
Analyze stored or streaming video for objects, scenes, activities, faces, and text so media teams can support indexing, discovery, moderation, or contextual recommendations.
“Content moderation and review”
Use SafeSearch, face and object analysis, and video-recognition capabilities to add automated signals to visual-content review processes.
“Visual descriptions and discovery”
Apply image descriptions, classification, search, or multimodal embeddings where an application needs to organize visual content or make it easier to find.
常见问题
What is Vision AI used for?
Vision AI is used to interpret images, scanned documents, and videos. Common applications include object detection, OCR, image classification and search, content moderation, document workflows, media archives, and visual recommendations.
Which Google Cloud service should I use for image analysis?
Cloud Vision API is positioned for quick integration of common image features such as labeling, OCR, face and landmark detection, and SafeSearch. Document AI is intended for document understanding, while Video Intelligence API is intended for video analysis.
What does Cloud Vision API return for OCR?
Depending on the OCR feature, it can return recognized text, text annotations, bounding boxes, and a hierarchy covering pages, blocks, paragraphs, words, and symbols. Document Text Detection is optimized for dense text, handwriting, and PDF or TIFF files.
How is Cloud Vision API priced?
Cloud Vision API uses usage-based pricing. Each feature applied to an image is a billable unit, and the product page states that 1,000 feature units are available free each month. Google Cloud also offers broader free credits for new customers, subject to its current terms.
Can Vision AI analyze video?
Yes. Google Cloud’s Video Intelligence API analyzes stored and streaming video, including objects, scenes, activities, faces, and text. It is a separate offering from the basic image features in Cloud Vision API.
