DeepSea V2 Development System

The TYZX DeepSea V2 Development System is a hardware and software development kit that enables product teams to build prototype projects and plan stereo vision implementation within their own products.

A Complete Development System for Real-world Vision Applications

The TYZX V2 Development System includes everything an engineer needs to build prototype 3D vision products, including a stereo camera, a stereo processor, development software and libraries, and demonstration applications.

The DeepSea V2 Development System includes:

• A DeepSea V2 Stereo Processor featuring a TYZX DeepSea 2 ASIC
• A factory-calibrated TYZX Stereo Camera
• SEER Software and sample applications

The DeepSea V2 stereo processor is a 1/2-length PCI card that connects directly to the TYZX stereo camera and provides depth and color information to a conventional PC. At its core is the high performance DeepSea 2 ASIC that performs TYZX' patented, pipelined implementation of the Census stereo correlation algorithm. The Census algorithm enables DeepSea cameras to correlate the images they see--despite changing lighting conditions and the subtle variations inherent among cameras--and provide a single, coherent representation of a scene. Census uses non-parametric stereo correlation based on relative intensities and values. By making use of relative similarities between images, rather than absolute values of brightness that cannot be duplicated in real-world environments, Census correlates stereo images even in rapidly-changing or poorly lit conditions.

Images from the stereo camera's two imagers are sent over a dedicated LVDS (low voltage differential signaling) interface to the Stereo Processor board. On-board firmware rectification corrects the incoming images for lens distortion and alignment while maintaining the lowest possible system latency. The typical output of the system is a stream of 512x480 images containing both depth and color data at 60 frames-per-second—an image stream fast enough to support applications that require split second decision-making. The TYZX stereo camera is capable of processing 512 x 2K images. For more information about the camera’s specifications and capabilities, click here.

The TYZX stereo camera is lightweight and compact. To reduce costs and power requirements, the camera features inexpensive off-the-shelf digital CMOS imagers and miniature lenses.

The DeepSea card within the TYZX camera contains the complete stereo computation engine, leaving the PC's processor and memory essentially unburdened and available for application processing tasks.
