ReadCalibrationResult 1: Inputs

Name

Type

Default

Description

sFilePath

PCCH

Full path of the file or relative path to the default directory on the target pc

paCameraMatrix

TcVnMatrix3x3_LREAL*

Returns the camera matrix

paDistortionCoefficients

TcVnArray8_LREAL*

Returns the distortion coefficients

paRotationMatrix

TcVnMatrix3x3_LREAL*

Returns the rotation matrix

paTranslationVector

TcVnVector3_LREAL*

Returns the translation vector

bRead

bool

Reading the file is triggered by a rising edge at this input.

nTimeout

unsigned int

VISION_ADS_TIMEOUT

Indicates the time before the function is cancelled.

ReadCalibrationResult 2: Outputs

Name

Type

Description

bBusy

bool

This output remains TRUE until the function block has executed a command, but at the longest for the duration supplied to the 'nTimeout' input. While bBusy = TRUE, no new command will be accepted at the inputs.

bError

bool

This output is switched to TRUE as soon as an error occurs during the execution of a command. The command-specific error code is contained in ‘nErrorId’. If the function block has a timeout error, 'bError' is TRUE and 'nErrorId' is 1861 (hexadecimal 0x745). Is reset to FALSE by the execution of a command at the inputs.

nErrorId

ULONG

Contains the ADS error code or the command-specific error code of the last executed command. Is reset to 0 by the execution of a command at the inputs.
