4.4.2
Temperature compensation
The camera firmware continuously monitors temperatures of LIMs, TIM, and base board, and corrects the
measured distance with cubic polynomials.
4.4.3
Combine sequences (HDR)
In order to improve the accuracy of distance data, the camera features the ability to combine up to 4 sequences
from the ToF sensor into one frame with improved accuracy. It uses the confidence values of the input frames to
calculate a new distance value for each pixel of the output frame.
The following registers are used to configure Combine mode:
•
NofSequ
: To configure up to 4 sequences. Minimum of 2 required for Combine mode.
•
IntegrationTime
,
IntTimeSeq1
,
IntTimeSeq2
,
IntTimeSeq3
: To configure integration times of up to 4
sequences
•
ModulationFrequency
,
ModFreqSeq1
,
ModFreqSeq2
,
ModFreqSeq3
: To configure modulation
frequencies of the sequences
•
ImgProcAdvanced
, bit 0: To enable combine mode
It is recommended that all sequences are recorded with identical modulation frequency when using Combine
mode.
4.4.4
Vernier
In order to combine the benefits of a smaller modulation frequency (higher unambiguity range) and a higher
modulation frequency (higher precision and accuracy), the camera features the ability to combine two sequences
with different modulation frequency into one frame.
The following registers are used to configure Combine mode:
•
NofSequ
: To configure 2 or 4 sequences.
•
IntegrationTime
,
IntTimeSeq1
,
IntTimeSeq2
,
IntTimeSeq3
: To configure integration times of up to 4
sequences
•
ModulationFrequency
,
ModFreqSeq1
,
ModFreqSeq2
,
ModFreqSeq3
: To configure modulation
frequencies of the sequences
•
ImgProcAdvanced
, bit 7: To enable combine mode
