NAOqi Vision - Overview | API
Namespace : AL
#include <alproxies/alvisualspacehistoryproxy.h>
Fills the visual grid with the current timestamp. This may be useful if the robot moves its torso since it makes the grid data irrelevant.
Parameters: |

Note
When the grid precision is changed the method ALVisualSpaceHistoryProxy::resetGrid() is automatically called to reset the grid data.
This memory key contains all the visual grid data formated as follows:
data = [zone_t1, zone_t2, ... ]
where zone_t1 = [[headYawAngle, headPitchAngle], timestamp] is the data corresponding to the zone_t1.
All zones are sorted by increasing timestamp, so t1 < t2 < ... . As a result, the first zone is the most outdated one and the last zone is the most recently updated one.
