Detailed Description

Worker object that processes color sensor output and updates stored reading.

Meant to be executed in separate thread.

Constructor & Destructor Documentation

ColorSensorWorker::ColorSensorWorker	(	const QString &	script,
		const QString &	inputFile,
		const QString &	outputFile,
		int	m,
		int	n,
		DeviceState &	state,
		trikHal::HardwareAbstractionInterface &	hardwareAbstraction
	)

Constructor.

Parameters

script	- file name of a scrit used to start or stop a sensor.
inputFile	- sensor input fifo. Note that we will write data here, not read it.
outputFile	- sensor output fifo. Note that we will read sensor data from here.
m	- horisontal dimension of a sensor.
n	- vertical dimension of a sensor.
state	- shared state of a sensor.

ColorSensorWorker::~ColorSensorWorker ( )

override

void ColorSensorWorker::init ( bool showOnDisplay )

slot

Initializes a camera.

Parameters

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

QVector< int > ColorSensorWorker::read	(	int	m,
		int	n
	)

slot

Returns dominant color in given cell of a grid as a vector [R; G; B] in RGB color scale.

If m or n are out of range, returns [-1; -1; -1]. Can be accessed directly from other thread.
