13. 1000 fps can be achieved in 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 D2048 3D03 04 camera In this mode the data of n images are bundled into one frame In the example shown in Fig 5 18 4 frames are combined into one frame FrameCombineNrFrames 4 In this case there are 4 times less software interrupts that indicate a new frame than without FrameCombine and the CPU load is significantly reduced Instead of receiving 4 images with 5 rows only one image with 20 rows is received which reduces the frame rate that sees the computer Without FrameCombine the CPU load on the computer might be too high to receive all images and images might be dropped The value n FrameCombineNrFrames can be set by the user This value should be set so that the resulting frame rate is well below 1000 fps e g at 100 fps E g if the camera shows a maximal frame rate of 4000 property AcquisitionFrameRateMax then FrameCombineNrFrames could be set to 40 to have a resulting frame rate of 100 fps Another example of FrameCombineNrFrames 2 is shown in Fig The PF 3D Suite supports this mode The FrameCombineNrFrames value should be set so that the resulting frame rate is well below 1000 fps FrameCombine Combined image Individual images F

Note that some profiles might be lost during this process as it takes more time to read out the laser finder window and therefore some triggers might be missed The criterion when the laser finder window should be used is based on the setting of the property Peak0_MovingR0IMinCol If the number of columns with a detected peak falls below this number as a percentage then the laser finder window will be used E g if Peak _MovingROIMinCol is set to 50 and the width of the ROI is set to 2048 then a laser finder window is used when less than 1024 columns 50 of 2048 carry a valid laser detection peak coordinate bigger than 0 5 2 3D Features 51 5 Functionality Note that in 2D amp 3DMode only the lower part of the laser finder window up to the height of the 3D ROI is sent to the camera output as the dimension of the output window must remain constant gt The horizontal position X and W of the 3D ROI and the laser finder window is the same and is set by the properties 0ffsetX and Width These values are not altered by the moving ROI feature e If the laser finder is disabled and the number of columns with a detected laser line is less than the value of Peak _MovingROIMinCol then the position of the 3D ROI is not modified Laser Finder Window Image Nbr 0 1 2 3 Figure 5 22 Laser Finder Moving ROI and status information Some values specific to the moving ROI feature are available in the status information fields see

32. Section 5 10 2 Specially the moving ROI status can be useful to monitor Moving ROI smoothing The moving ROI feature uses the minimal and maximal laser line coordinate to calculate the position of the 3D ROI If there are outlier pixels e g due to reflections then the calculation can produce a window position that is not optimal In this case it might be better to smooth the laser coordinate prior to the position calculation The property Peak _MovingROI Smoothing sets the smoothing level None No smoothing is applied MA8 A moving average of 8 pixels is used for smoothing MA16 A moving average of 16 pixels is used for smoothing which results in the highest amount of smoothing Smoothing is only used for the calculation of the position of the 3D ROI in the moving ROI feature but has no impact on the 3D data output of the camera 52 Considerations in using moving ROI The moving ROI feature should be considered if the horizontal position of the detected laser line changes in the course of the detection A typical case is the examination of flat surfaces the deviation of the laser line in every profile is rather small but the vertical position of the detected laser line might change due to vibrations or if the surface is not parallel to the conveyor belt Gradual changes of the vertical position are optimal for the moving ROI feature Abrupt changes can be handled by the Laser Finder feature see Section 5 2 16 at the cost of losing so
