Product Overview
The ALG Tech automotive stereo camera (ALG Stereo Camera) is a product built for intelligent vision, delivering high-precision 3D vision information for autonomous driving, robotics, industrial automation, rail transit, and more. It uses high-performance automotive-grade CMOS image sensors with back-side-illuminated and composite pixel technology and a dynamic range exceeding 120 dB — adapting beautifully to outdoor mobile scenarios and outputting detail-rich, high-contrast images whether in direct sunlight or near darkness.
An SDK development kit is provided with support for mainstream platforms across the x86 and ARM families (e.g., Jetson, Raspberry Pi). The SDK supports standard driver frameworks and common development environments (e.g., V4L2, ROS), greatly reducing development and integration effort so users can focus on acquiring data and building applications.
Data is transmitted over the GMSL 2 protocol with high bandwidth and low latency, and the module is powered via PoC — combining reliable connectivity, strong interference immunity, and long transmission distance. The product features a rugged, durable industrial structure rated IP67, with an ultra-wide operating temperature range of -40°C to +85°C for dependable outdoor operation in harsh environments.
