Peak Detection Window

Preliminary Prototype | All right reserved | All Information without warranty
The Peak Detection Value defines the length of echoes processed into a single object. This value enables the fusion of complex
surfaces into less points. Additionally noise can be filtered out even when using small echo detection thresholds. Additionally the
stability of the point detection is enhanced due to more echo location data being processed.
Peak Detection Window
Command
sPeak
Effect
Sets the kernel size (window width) that is applied on raw ADC signals to detect valid echoes (peaks in the raw
ADC signal). A low value will allow for better separation of multiple objects that are close to each other. A high
value will result in "smoother" and more stable detections
Parameter
5-digit unsigned integer representing the window width size of the the object filter
Applicable Values
Default = 3, min. = 1, max. = 5
Example
CsPeak00003\r
for size of 3
Please note the tendency of smaller objects to fuse when higher values are configured. Smaller objects with similar relative
position to the sensor as bigger objects are fused with the bigger object. Note that each object fusion will change the resulting
coordinates of the bigger objects weighted by the amplitudes of both objects. Smaller objects in close proximity to bigger objects
tend to disappear if the window size is set to values above 2.
Small (1-2) = Small Window Size
Medium (3-4) = Medium Window Size
Large (5) = Large Window Size
The Small and Medium
configuration fits best for
most purposes. A value of
1 is best for close range
applications.
On
the
Medium
configuration
small
objects with proximity to
bigger objects can fuse.
The Large window setting
is
fusing
even
bigger
objects. It can be used for
distance
detection
to
avoid noise.
