Caution
Be careful in setting different integration times and frame rate combinations. Not all
combinations are possible! Without appropriate cooling the device may be damaged! Refer
to the Hardware User Manual for more information.
The FITP is also used for the camera’s power control, if it is powered by PoE (see chapter 3.6). If the camera
register
Integration Time
or
Framerate
is modified, the entered value is used to calculate the FITP. Should
the FITP violate the maximum allowed power, then the value is automatically corrected before it is applied.
The corrected value can be read back via the same register. Also, if any correction of integration time or
frame rate took place because of PoE constraints, Bit[10] of the
Status
register will be set.
4.9
Sequencing
The Argos 3D-P320 allows the configuration of up to 2 sequences on the TIM. These sequences are
captured immediately after each other by the TIM. Each sequence can be configured with individual
integration time and modulation frequency.
If the camera’s video mode is disabled (see register
Mode0
), and the camera is manually triggered, each
trigger will generate as many sequences as currently configured.
The number of sequences can be configured in register
NofSequ
.
For sequence 0, use registers
IntegrationTime
and
ModulationFrequency
to set integration time and
modulation frequency, respectively.
For sequence 1, use registers
IntTimeSeq1
and
ModFreqSeq1
.
Each sequence is processed and streamed by the camera as one individual frame. Each frame header
contains the sequence number in field
SequenceNumber
.
4.10
Illumination Pre-Heating
The camera supports pre-heating of the LEDs on the LIMs immediately before capturing. Pre-heating is
accomplished by applying a defined modulation signal to the LEDs.
Pre-heating is enabled by setting a pre-heating time. For each sequence, an individual pre-heating time can
be configured.
Sequence 0 pre-heating time is configured in register
IllPreheatingTime
.
Sequence 1 pre-heating time is configured in register
IllPreheatingTimeSeq1
.
Common parameters for pre-heating are the frequency of the modulation signal (register
IllPreheatingFreq
)
and the duty cycle of the modulation signal (register
IllPreheatingDutyCycle
).

Distance Offset Calibration
Each Argos 3D-P320 is offset-calibrated out of factory.
