Automaker Processes Hundreds of Millions of Road Images with Spark AI Function

AI summary

An unnamed leading automaker reportedly processed hundreds of millions of road images on Alibaba Cloud EMR Serverless Spark, using AI Function for multimodal scene extraction and image vectorization. The workflow handled road merging and traffic-light scenarios, wrote embeddings to downstream databases, and supported scene retrieval, sample selection, and training-data preparation.

In-depth insight

The report describes a production-scale use case that integrates multimodal extraction and vectorization directly into existing Spark data pipelines.

一张道路图片,如何变成可分析的场景信息?海量图片,又如何转化为可检索、可筛选的数据资产?

在汽车行业,图片中包含的道路和交通信息,需要经过提取、整理,才能用于后续分析和样本筛选。多模态模型提供了新的处理方式,而批量调用、异常处理和结果写入,则需要与现有数据处理作业一起完成。

某汽车头部客户基于阿里云 EMR Serverless Spark AI Function,在分合流、红绿灯等场景中开展多模态数据处理,并将向量化结果衔接至下游数据库,为后续场景检索、样本筛选及训练数据集构建提供支撑。

大规模模型调用的工程挑战

当处理对象从少量图片扩展到持续积累的业务数据时,模型调用就需要与数据读取、并行执行、结果解析和数据写入共同协作。
