#include <ArRangeDevice.h>
Inheritance diagram for ArRangeDevice:
This class maintains two ArRangeBuffer objects: a current buffer for storing very recent readings, and a cumulative buffer for a longer history of readings. The maximum sizes of each buffer can be set in the constructor or resized later. Range device readings are most often represented as a point in space (X,Y) where the sensor detected an object. (Therefore an ArPose object may only have X and Y components set). Some devices provide extra information in a "raw" buffer, or in lists of more detailed ArSensoReading objects.
Subclasses are used for specific sensor implementations like ArSick for SICK lasers and ArSonarDevice for the Pioneer sonar array. It can also be useful to treat "virtual" objects like forbidden areas specified by the user in a map like range devices. Some of these subsclasses may use a separate thread to update the range reading buffers, and so this base class provides "lock" and "unlock" methods which you should use when accessing device data.
A range device may have an ArRobot object associated with it. A range device may also be associated with an ArRobot by calling ArRobot::addRangeDevice(). ArRobot provides functions which operate on all such associated ArRangeDevice objects. This is a convenient (and thread-safe) way to access all range device data without depending on a specific set of individual range devices. For example, you can find the closest reading in a box or a polar section, no matter if that reading originated from the sonar, a laser, or other device.

| void ArRangeDevice::adjustRawReadings | ( | bool | interlaced | ) | [protected] |
This call should be called by the range device every robot cycle before the range device makes new readings (and even if it isn't adding any that cycle)... it will adjust the raw readings by the robot odometry offset. The robot should be locked when this happens (which should be the case if you're doing it in the robot callback). The code currently assumes that all readings were taken at the same point, so if that isn't true with your device then you can't use this mechanism.
| virtual const std::list<ArSensorReading *>* ArRangeDevice::getAdjustedRawReadings | ( | void | ) | const [inline, virtual] |
Gets the raw unfiltered readings from the device (but pose takens are corrected).
The raw readings are the full set of unfiltered readings from the device. They are the latest readings. You should not manipulate the list you get from this function, the only manipulation of this list should be done by the range device itself. (Its only pointers for speed.)
This is like the raw readings but they were corrected for the robot odometry offset (just the pose taken, and encoder psoe taken).

| void ArRangeDevice::setMaxDistToKeepCumulative | ( | double | maxDistToKeepCumulative | ) | [inline] |

Sets the maximum distance a cumulative reading can be from the robot and still be inserted.
| maxInsertDistCumulative | The maximum distance a cumulative reading can have from the robot's current position and still be inserted into the cumulative readings, this is applied in the addReading call so range devices need to call that for this to take effect. |
| void ArRangeDevice::setMaxSecondsToKeepCumulative | ( | int | maxSecondsToKeepCumulative | ) | [inline] |
