Detailed Description

Uses virtual line sensor to detect x coordinate of a center of an object that was in camera's field of view when "detect" method was called.

Used mainly to follow the line.

Member Function Documentation

virtual void trikControl::ObjectSensorInterface::detect ( )

pure virtualslot

Detects the color of an object in center of current frame and memorizes it.

virtual QVector<int> trikControl::ObjectSensorInterface::getDetectParameters ( ) const

pure virtualslot

Get values returned by last "detect" operation.

Returned vector has 6 components - hue, saturation and value of a dominant color (got by "detect") and hue, saturation and value tolerance factors.

virtual void trikControl::ObjectSensorInterface::init ( bool showOnDisplay )

pure virtualslot

Initializes a camera.

Parameters

showOnDisplay - true if we want an image from a camera to be drawn on robot display.

virtual QVector<int> trikControl::ObjectSensorInterface::read ( )

pure virtualslot

Returns x, y coordinates and size of an object in a form of vector [x; y; size].

Returns 0 in every field if detect() was not called.

virtual void trikControl::ObjectSensorInterface::stop ( )

pure virtualslot

Stops detection until init() will be called again.

void trikControl::ObjectSensorInterface::stopped ( )

signal

Emitted when sensor is stopped successfully.
