IMAQ Get Rectified Image From Stereo

Interpolation Type specifies the interpolation method used to generate the output image. The default is Zero Order. The following options are valid:

Zero Order (0)

Rounds to the nearest integral pixel location

Bi-Linear (1)

Uses linear interpolation in both the x- and y-directions to compute the pixel location

Binocular Stereo Session is the reference to the binocular stereo vision session on which this VI operates.

Image Src is the reference to the input image from either the left or right camera in the stereo system.

Image Dst is a reference to the image that will contain the rectified image after the VI runs.

error in (no error) describes the error status before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.

code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.

cstr.gif

source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.

cenum.gif

Reference Coordinate System specifies which camera the Image Src is acquired from.

Left Camera (0)

The image is acquired from the left camera.

Right Camera (1)

The image is acquired from the right camera.

Binocular Stereo Session (dup) is the reference to the stereo vision session on which this VI operates.

Image Dst Out is the reference to the rectified image.

error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.

ibool.gif

status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.

ii32.gif

code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.

istr.gif

source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
