How to calculate the required pace when I need to scan the surface of 1 meter moving at 0.5 meter/second

I need to analyze a surface of the mobile object with a camera.

My question is: the object surface is 1 meter in length and image size of my camera picture is 2048 * 2048, then, what is the frequency of images I need?

My mapping is 1 mm = 10 pixels

so 1000 mm = 10000 pixels

Is is like 10000 pixels / 2048 pixels = approximately 5 frames?

Is - this law to determine the frames per second?

Thanks in advance

You confuse your pace and your total number of frames.

Rate: the speed is 500 mm/s.  Each frame contains 200 mm.  500 mm/s / 200 mm = 2.5 frames per second.

Number of images: length is 1000 mm.  Frame is 200 mm.  1000 mm / 200 mm = 5 frames.

If you need photos at 2.5 frames per second for 2 seconds to get 5 frames.

Of course, this assumes no overlap.  In practice, it's a good idea to have overlapping slightly if you have no flaws just at the edge of your image.  That's also assuming that you can move your object to exactly 500 mm/s.

  • How to calculate the execution time of a SCTL in FPGA VI?

    Hello

    Can someone guide me that how to calculate the execution time of a SCTL for an iteration in the FPGA VI?

    Thank you and best regards,

    Rashid

    Hello r,.

    A SCTL will always run in a beat the clock it has been linked to.  So, if you use a 40 MHz clock, this loop will run in 25 ns.  If the code cannot complete in that, or if it requires two graduations of the watch to do the calculation, your code does not compile, then you have the guarantee that this will always be how long it takes this piece of code to run.

  • How to calculate the sum of two digital form fields based on the selection of the checkbox.

    I have a form in Acrobat Pro who needs a custom calculation. How to calculate the sum of two digital form fields based on a selection of the checkbox. I have three number fields. Field-A and B are simple one or two digits. Field-C is the sum, or the total field. I want to field-C have a control box which, when turned on and off, just gives a. gives the sum of A + B

    _ Field - 2

    _ Field - A 4

    The custom field C calculation script could be:

    (function () {
    
        // Get the values of the text fields, as numbers
        var v1 = +getField("A").value;
        var v2 = +getField("B").value;

        } else {
            event.value = v1;
        }
    
    })();
    

    Replace 'A', 'B', and 'CB' with the real names of the fields.

    Checkpopint operations which are drivern by the volume of interval and log checkpoint are those that are 'Checkpointer' in the output of ttCkptHistory. Control points can also occur for other reasons, for example when the data store is stopped, when it is loaded in memory and recovery is necessary. These kinds of control point are marked as "Static" and "Subdaemon". You can see three of those in the output.

    The output, it seems you're checkpointing about every 4 minutes. Assuming the target settings (interval 600 seconds, Journal volume of 1 GB) were already in place at the time of these control points has occurred then it seems that all of these were led by the volume of the journal rather than the checkpoint interval (that you generate ~ 1 GB of log about every 4 minutes).

  • How to calculate the CPU Ready on Cluster DRS via Powercli?

    Hi all!

    I have a DRS Vsphere cluster. I want to know what is the value of the loan of CPU I have in my group.

    For example, I get 20% of powercli value, it is normal for the cluster, but if I have 100% or more, I have a problem.

    How to achieve via Powercli? And how to calculate the percentage values correctly?

    I know, I can get all values of CPU Ready of VMs cluster, but IT is not the same thing, I need overall value of CPU Ready.

    Thanks in advance!

    As far as I know you can get the cpu.ready.summation for ESXi nodes or VMs.

    For a cluster, you will need to get the value of each node in the cluster ESXi and then take the average.

    The metric cpu.radey.summation is expressed in milliseconds.

    To get a percentage, you need to calculate the percentage of loan period during the interval during which it was measured.

    Something like this (this will give the loan current %)

    $clusterName = "mycluster.

    $stat = "cpu.ready.summation".

    $esx = get-Cluster-name $clusterName | Get-VMHost

    $stats = get-Stat-entity $esx - Stat $stat - Realtime - MaxSamples 1 - forum «»

    $readyAvg = $stats | Measure-object-property - average value. Select - ExpandProperty average

    $readyPerc = $readyAvg / ($stats [0].) IntervalSecs * 1000)

    Write-Output "Cluster $($clusterName) - CPU % loan $(' {0:p}'-f $readyPerc).

  • How to calculate the size of a VMFS volume?

    Creating a new partitiontable after ESXi 4 wiped empty was pretty easy with fdisk.
    These days with partedUtil and ESXi 5 is not so trivial.

    Consider that we have a disk/Lun, which looks like this

    ~ # partedUtil get /vmfs/devices/disks/mpx.vmhba1:C0:T4:L0
    93990 255 63 1509949440

    and suggests that the original - now messed the Volume was created with ESXi 5.
    How to calculate the value of the end in the sector so that I can recreate the VMFS partition like this:

    partedUtil setptbl ' / vmfs/devices/disks/mpx.vmhba1:C0:T4:L0 ' TPG '1-2048 ? '. AA31E02A400F11DB9590000C2911D1B8 0 "


    In this case, the correct value is 1509949349, but how do I calculate if I don't know the correct value?

    Hello

    the output of the command "partedUtil get /vmfs/devices/disks/mpx.vmhba1:C0:T4:L0" will be useful in your case, it's "93990 255 63 1509949440".

    gives us the values for C/H/S (cylinder/head/sector).

    A VMFS volume partition must end on the limit of a cylinder, so selecting the last sector of the partition table should be done using the formula endSector = (C * H * S - 1).

    who is '1509949440-1' = 1509949349.

    Concerning
    Smilee

    What is your goal? The subcube in HFM is a concept that applies to application layer - not so much to the database layer. The size of the subcube is the unique number of sheets (data values for January - December inclusive, for example) for the given entity, a triplet of currency or node Parent.Child. Should be considered for accounts of parent and customs that do not exist in the database, but are calculated in the RAM of the application layer.

    So if your goal is to find the largest subcubes, you could do this by querying the database and by counting the number of records per entity value (tables DCE) or combination of entity parent.child (tables of the DCN). I am not versed in SQL, but I think the script below you would just the size of the pattern and not the sizes of subcube.

    See Accelatis.com for a third party software product that can do it for you. The function is called the subcube Analyzer and was written by the same team that wrote HFM, then they should know how :-)

  • How to calculate the month on month growth rates in an OBIEE application?

    Hi all

    I would like to ask for your help on how to calculate the months on growth rate previous/[(last month-previous month) month * 100%] in a query OBIEE. This report should always be calculated for the last 2 months available.

    I have the following query:
    Month0 | Months1. Month2
    Produces a 500 | 100. 200
    Product B 600 | 300. 150

    I would like to add month on month column as follows:
    Month0 | Months1. Month2. Month on Month (%)
    Produces a 500 | 100. 200 | + 100.00%
    Product B 600 | 300. 150. -50.00%

    I tried to add a calculated item, but it failed because I couldn't find a way to not show the column calculated in percent with 2 decimal places. In addition, I would ideally prefer to have an automatic update but as far as I understand it can be done in the automatically calculated item

    I also tried to add a new column to the column area and to filter the results for the last month, then for the previous month and then based on that to calculate the necessary ratio but unfortunately it does not work.

    Thank you in advance your advice

    Hello

    The best way to solve this problem is by using the function Ago. With this, you can create a logical column for the previous month. Then you will have 2 columns available with which you can do your calculations.

    If you want to do this with a calculated item (don't know if formatting will work for you), but you can do the more general calculation using $1 for the $2 for the 2 column and 1 column in your calculation. If ($x) columns will change with the columns in your report.
