4.2.9 Frame Combine

Very high frame rates, that are well over 1000 fps, can be achieved in the 3Donly mode. Every
frame (image) activates an interrupt in the GigE software which will issue a high CPU load or
the frame rate can not be handled at all by an overload of interrupts.
To solve this issue, the FrameCombine mode has been implemented in the MV1-D1312-3D02
camera. In this mode, the data of f images are bundled into one frame. The value f
(=FrameCombineNrFrames) can be set by the user. The PF 3D Suite supports this mode. An
example of FrameCombineNrFrames=4 is shown in Fig. 4.11.
Aborting Frame Combine
There exist possibilities to transmit the combined frame even if there is not enough data to fill
it. E.g. it can be desirable to get the 3D data immediately after an item on the conveyor belt
has passed.
FrameCombineTimeout A timeout can be specified after which the combined frame will be
transmitted, regardless if there was enough data to fill it. The timeout counter is reset
after each frame and counts until a new trigger has been detected or until the timeout is
reached.
A FrameCombineTimeout value of 0 disables the FrameCombine timeout fea-
ture.
FrameCombineAbort The transmission of the combined frame is forced by writing to the
FrameCombineAbort property.
When the FrameCombine is aborted, then the remaining data in the combined frame will be
filled with filler data: the first two pixels of every filler row have the values 0xBB (decimal 187)
and 0x44 (decimal 68). The remaining pixels of the filler rows have the value 0.
The FrameCombine mode is only available in 3Donly mode.
When acquisition is stopped, then a pending combined frame will be discarded.
To get the pending combined frame, a FrameCombineAbort command must be
sent prior to stopping the acquisition.
