Rishabh e9c0e50185 AP_Proximity: Filter out land detected by sensors 2021-03-09 11:02:26 +09:00
Rishabh 044e1850d4 AP_Proximity: Add a low pass filter per face for distances 2021-03-08 16:33:20 +09:00
Peter Barker 9a66a1564c AP_Proximity: only send distance_sensor messages if valid data seen 
In the case you only have a forward-pointing LIDAR we'd send messages
for each of the other orientations from proximty's horizontal-distances
array, chewing up bandwidth and processing time.

Andras Schaffer 43bef1ac9e AP_Proximity: fix proximity ignored zone calulation 
It seems there was a typo in the checking of proximity ignored zones.

Randy Mackay 74f1899aeb AP_Proximity: boundary_points requires only one valid distance 
Object avoidance is possible with just one valid distance
Boundary is initialised in new init_boundary function to be 100m from
vehicle
If sectors do not have valid distance measurements, we use the distance
from adjacent sectors.  This conveniently leads to a concave shaped
boundary that keeps the vehicle from travelling into the dataless sector.

Randy Mackay fbbd13db75 AP_Proximity: add get_object methods for use with non-GPS avoidance 2016-12-20 19:47:56 +09:00
Randy Mackay 54a87ad35c AP_Proximity: set minimum boundary distance 
AC_Avoidance will not stop if it thinks the vehicle is on or outside the polygon.  Setting a minimum distance ensures the vehicle is always within the polygon.
 2016-11-27 15:05:48 +09:00
Randy Mackay 57ae14ab4c AP_Proximity: add get distances, distance_max, distance_min 
These are used to send distance-sensor messages to the ground station

Randy Mackay 6293fa1595 AP_Proximity: add boundary points for object avoidance 
This returns a fence which can be used for object avoidance by AC_Avoidance

Randy Mackay 26332251f5 AP_Proximity: add ignore areas 
Only SF40c uses these ignore areas for now at least.
It is safe to increase the eeprom locations for the 2nd proximity instance because we only define a single instance.

Randy Mackay 87dea46f5d AP_Proximity: add get_closet_object for use in pre-arm checks 2016-11-27 12:03:06 +09:00
Randy Mackay f594a5a7d6 AP_Proximity: move sectors to backend 
This prepares for sectors to be re-used by the SITL driver

Mathieu OTHACEHE 152edf7189 Global: remove mode line from headers 
Using a global .dir-locals.el file is a better alternative than
reincluding the same emacs header in every file of the project.
