Introduction to Tara
-
See3CAM_Stereo
The Tara - See3CAM_Stereo, hereafter called as Tara, is a UVC compliant USB 3.0
SuperSpeed Stereo vision camera from e-con Systems, a leading embedded Product
Design Services company which specializes in the advanced camera solutions. Tara is
based on MT9V024 stereo sensor from OnSemi and it supports a maximum
resolution of WVGA at 60fps over USB 3.0 in uncompressed format. Tara is the latest
member of the Stereo Vision family of USB3.0 SuperSpeed camera products
launched by e-con Systems.
Tara is a monochrome camera with the S-mount (also known as M12 board lens)
lens holder. The S-mount is one of the most commonly used small form-factor lens
mounts for board cameras. Tara has two OnSemi's 1/3-inch MT9V024 image sensors
separated by an inter-ocular distance or base line of 60 mm. With USB 3.0 interface
to the host PC, Tara can stream WVGA (2 x 752 x 480) resolution at 60 fps, VGA (2 x
640 x 480) resolution at 60 fps and QVGA (2 x 320 x 240) resolution at 60 fps in
uncompressed Y16 (8 Bit pixel data from each camera) and RGB24 (10 Bit pixel data
from each camera). It also has ability to capture still images. Tara is also backward
compatible with USB 2.0 host ports and does not require any special camera drivers
to be installed in the host PC. In USB 2.0, the camera is capable of streaming in lower
frame rates.
The commonly used functions are put into a single namespace for modularity, in-
order to reuse them in the examples. Tara is the namespace that contains the
following three classes:
i.
TaraCam Parameters
ii.
Disparity
iii.
CameraEnumeration
Description
Tara namespace contains many commonly used functions. Loading the calibrated
files from the camera flash, computing disparity map, rectification of frames, camera
enumeration and initialization, etc. are some of them.
Note:
For Sample usage of the API’s, refer source code.
