35    <h2>Return Values</h2>
36    <div class="section">Returns the parallax in the measurement chart for a VGA image. The return value represents the translation of the left camera image based on the right camera image. This is measured in pixels. </div>
37    <h2>Description</h2>
38    <div class="section">
39      <p>Calculates the parallax in the measurement chart when the stereo cameras' calibration data is measured.</p><P>In addition to the horizontal image shift caused by errors in the left and right camera placement, the <CODE>translationX</CODE> member variable of the <CODE><a href="../../../nn/camera/CTR/StereoCameraCalibrationData/Overview.html">nn::camera::CTR::StereoCameraCalibrationData</a></CODE> structure includes the parallax caused by the separation of the left and right cameras.
40            </P><P>
41                By subtracting this function's return value from the <CODE>translationX</CODE> member variable, you get the horizontal shift in the measurement chart caused by camera placement errors.
