FDTSearchAngle

uEye ActiveX Manual Version 4.00

FDTSearchAngle

Description

FDTSearchAngle sets a search angle for face detection. You can set an angle of 0°, 90° or 270° (clockwise). The face detection feature will take only those faces into account that match the set facial orientation angle. You can use this function, for example, to increase the detection reliability when you have turned the camera upright.

To detect upside-down faces, you have to turn the camera or enable the mirror function.

Hinweis

This function is currently only supported by the USB uEye XS camera model.

Hinweis

Control properties are only supported for programming in C# and VB.
