Multimodal Annotation Services for Vision Language and Multi Sensor AI Models

Multimodal Annotation Services
Multimodal AI systems combine visual, textual, audio, and sensor information to understand complex real world scenarios. These models require carefully structured datasets where every modality is aligned, synchronized, and annotated in a consistent way.DataVLab supports companies building advanced multimodal models such as vision language models, recommendation systems, robotics perception, and autonomous systems. Our teams work across images, videos, transcripts, audio clips, LiDAR scans, human feedback data, and metadata. We design workflows that ensure each modality is annotated with compatible labels and linked to the correct frames, timestamps, or segments.Our multimodal annotation services cover a wide range of use cases such as interpreting user queries paired with images, labeling video and text sequences for instruction following, linking audio cues to events, or aligning structured data with visual observations. All annotations are processed through multistage quality control to guarantee consistency across every modality.
Aligned labeling across images, text, audio, video, and sensor modalities for complex AI workflows.
Custom schemas for vision language training, multimodal reasoning, and instruction based models.
Scalable annotation with multilevel QA to ensure consistent alignment across datasets.
How DataVLab Supports Multimodal and Vision Language Model Development
Our workflows are designed to help teams train models that rely on multiple inputs such as images paired with text, audio aligned with video, or sensor streams combined with metadata.

Image and Text Pair Annotation
Labeling input pairs for vision language models
We annotate images with captions, instructions, answers, or classifications to support training of multimodal reasoning systems.

Video and Transcript Alignment
Synchronizing spoken or written content
We align transcripts with video frames, annotate speaker turns, and mark relevant segments.

Audio Event Labeling
Linking sound cues to context
We annotate audio segments and connect them to corresponding moments in video or metadata.

LiDAR and Image Co Annotation
Multisensor labeling workflows
We annotate LiDAR point clouds and match them with camera frames for robotics or navigation systems.

Instruction and Response Dataset Preparation
Creating multimodal prompt datasets
We pair prompts, images, and expected answers to support instruction based multimodal models.

Metadata and Visual Alignment
Structuring labels across heterogeneous inputs
We match structured data with corresponding image, video, or text elements to support advanced classifiers and retrieval systems.
