March 21, 2012, e-con Systems announces Capella, a Stereo Vision camera based on Texas Instruments’ OMAP/DM37x family of processors and Gumstix Overo computer-on-module (COM) series. Capella includes a DM3730-based Gumstix Overo Water Storm COM, a Gumstix Tobi expansion board and e-con’s camera daughter board e-CAM_9V024_STEREO. Capella comes with a Software Development Kit with full source code for application development on top of V4L2 or OpenCV, enabling customers to develop their own StereoVision Camera based applications. e-conSystems also provides sample applications with source, for applications such as synchronous stereo image capture, depth measurement etc. Capella targets product companies keen to integrate Stereo Vision in their product design featuring
- 3Danalytical applications such as machine vision, mobile robotics (obstacle detection) and automotive applications including computer aided navigation anddriver guidance.
- 3Dobject reconstruction applications such as reconstructing 3D details of sculptures, monuments, human faces etc.
- 3D video recording and playback
- 2D synchronous dual-camera applications where, two simultaneously captured images of same (or different) objects are required.
Capella runs Linux 2.6.35 and has Ethernet, HDMI Video port, USB OTG port, and a serial interface for Linux console. The Stereo Camera Engine driver is V4L2 compatible and is available with an OpenCV interface patch allowing customers to develop applications based on plain V4L2 API or the OpenCV stack. The Stereo Engine driver exposes three V4L2 interfaces to the application developers to capture the left, right and combined left+right video streams.
The SDK contains sample applications using both the V4L2 interface and also OpenCV stack. The e-CAM_9V024_STEREO is powered by a pair of1/3” Global Shutter Monochrome Aptina CMOS image sensor MT9V024, with an active area of WVGA 752(H) x 480(V) (360690 pixels) and capability of delivering Synchronous Parallel 736(H)x480(V) Monochrome video of 8-bpp gray scale images at 30fps.The cameras come with pre-aligned and pre-calibrated M12 lenses on an S-mount lens holder and customers can select and calibrate the lens for specific requirements. The two cameras are separated by a distance of 100mm(the baseline). This baseline allows accurate measurement to a depth of three meters.
Customers interested in increasing the baseline or changing the lenses can approach e-con Systems’ for customization.
