MBMC Request

Hi, I would like to get binary files of following:

1) 1bpp*1B_1bpp*1R_1bpp*12G_1111uSec

(B R Gsix gray code images and five phase shift images with exposure time= 1111us)

2) 1bpp*1B_1bpp*1R_1bpp*12G_3333uSec

(different exposure time from [1].)

3) 1bpp*1B_1bpp*1R_1bpp*11G_1111uSec

(B R G + five gray code images and five phase shift images with exposure time= 1111us)

4) 1bpp*1B_1bpp*1R_1bpp*11G_3333uSec

(different exposure time from [3].)

They will be used for 3D scanning with color information.

Sincerely,

Eunsang Ko

  • Hi Eunsang,

    I have created your sequences. They will be posted here: software-dl.ti.com/.../dlp3000mbmc.html

    Please allow 24 hours for them to appear. Please let me know if there are any errors.

    Thank you,
    Paul
  • Hi Paul,

    Thanks for creating the sequences.

    However, you have a mistake at the last sequence:

    NOT: http://software-dl.ti.com/dlp/embedded/catalog/dlp3000/28Oct2016_09_09_AM.zip

    CORRECT: http://software-dl.ti.com/dlp/embedded/catalog/dlp3000/mbmcfiles/28Oct2016_09_09_AM.zip

    Anyway, I successfully downloaded the four sequences.

    Thank you,

    Eunsang Ko

  • Dear Paul,

    Should I request a new binary file if I change the exposure time of binary files? I want to change the trigger period to >= 1111 uSec that means exposure time will be about 950 uSec?

    Sincerely,

    Eunsang Ko

  • Hi Paul,

    Unfortunately, I have been having trouble when setting the MBMC sequence.

    My problem is DLP LightCrafter GUI goes "not response" after clicking the sequence settings "Set" button which is shown in [step 10, pp. 42, dlpu006e.pdf] regardless of other sequences and input trigger(auto or command).

    Could you do me a favor?

    Thanks,

    Eunsang Ko

  • Eunsang,

    It's okay to ask for another sequence in this thread. Can you please detail for me what sequence you would like?

    I'm sorry you're having difficulty getting the sequences to work. Let me try them on my Lightcrafter and see if I can get them to work. You asked for a favor though - is there something you would like me to answer or do?

    Thanks,
    Paul
  • Could you make other two sequences with exposure time=950 uSec, respectively? (1b 1r 12g and 1b 1r 11g)

    However, if the trigger period time of sequences is greater than 1111 uSec, please decrease the exposure time of sequences.

    Because, I want to use the camera with 900 fps grabbing speed.

    Second, about the not responding GUI and Lightcrafter,

    Just, I would like to know why Lightcrafter doesn't respond.

    If you success the test of my sequences, please let me know your firmware version. (Is there problem when using Keynote's firmware version?)

    Thanks,

    Eunsang Ko

  • Oh,,,, Once I install TI's firmware, MBMC sequences work well. :)

    However, can I use the "Play Once" function?

    If not, please make two sequence file(1b 1r 12g and 1b 1r 11g) with exposure time=950 (maximum) and trigger period=1111 (minimum).

    Thanks,

    Eunsang Ko

    p.s. I don't know why getting the firmware versions is failed.

  • Hi Eunsang,

    Using the TI lightcrafter software will be better, I'm glad you got the MBMC sequences working. I've posted your new sequences to link provided above. Please allow 24 hours for them to show up.

    You should be able to use the "Play Once" function. Are you having issues with it?

    -Paul
  • Thanks,

    "Play Once" function works well if I use DLP LightCrafter Software - 5.0.0 not Keynotes's software.

    However, in my sequence, the number of images and the number of pattens are 14 (1b + 1r + 12g) and 24 (1 bit patterns and black patterns), respectively.

    Thus, I think trigger signals should be generated 14 times is right, but it is generated 24 times.

    As a result, the pair of images (sequence) are not matched because LightCrafter projects 14 images.

    What I missed?

    Thanks,

    Eunsang Ko

    p.s. I entered very greater value into 'Trigger Period' to watch whether LightCrafter works well.

  • Eunsang,

    I am not following. Your sequence has 14 patterns - that is the way that I built them for you.

    When you use the sequence, you expect 14 triggers but see 24 triggers?

    It looks like you have told the GUI that there are 24 patterns, so it will give you 24 triggers. Where did the number 24 come from? If you would like a 24 pattern sequence with 24 triggers, then I will have to build you that.

    Please clarify if you can.

    Thank you,
    Paul
  • Hi Paul,

    I was in trouble that trigger signal and pattern image are mismatched because I am using "Play Once".

    When using Play Once, pattern images are projected of following: 1b+1r+12g+1b+1r+8g // [next] // 4g+1b+1r+12g+1b+1r+4g // [next] // 8g+ ...

    However, maybe, I can resolve this problem by updating my code or not using Play Once.

    Thank you very much.

    Thanks,

    Eunsang Ko

  • Hi Paul,

    Could you build two MBMC sequences of following?

    1) 1bpp*1B_1bpp*1R_1bpp*22G_850uSec

    2) 1bpp*1B_1bpp*1R_1bpp*22G_950uSec

    1bpp black pattern image should be removed to use to my work.

    I'm sorry for disturbing you.

    Maybe, this request is final. :)

    Thanks,

    Eunsang Ko

  • Hi Eunsang,

    The sequences have been created, please allow 24 hours for them to appear.

    Thank you,
    Paul
  • Hi Paul,

    How is it going?

    Would you mind if I request two sequences of following?

    1) 1 * 1bpp red + 1 * 1bpp green + 22 * 1bpp blue with 2225 uSec exposure (Trig. Period >= 2700)

    2) 1 * 1bpp red + 1 * 1bpp blue + 22 * 1bpp green with 2225 uSec exposure (Trig. Period >= 2700)

    In addition, can I update the binary file to change exposure time myself?

    If possible, please let me know how I set the reset code values in binary file.

    For example, in Francois Torner's Request 

    1) 5000 uSec exposure:

    0192  4048 f802    no operation      63491
    0193  4048 f803    wait              63492
    0194  4048 f803    wait              63492

    2) 10000 uSec exposure:

    0192  4048 f801    no operation      63490
    0193  4048 f803    wait              63492
    0194  4048 f803    wait              63492
    0195  4048 f803    wait              63492
    0196  4048 f803    wait              63492
    0197  4048 f803    wait              63492

    3) 15000 uSec exposure:

    01a1  4050 f800    no operation      63489
    01a2  4050 f803    wait              63492
    01a3  4050 f803    wait              63492
    01a4  4050 f803    wait              63492
    01a5  4050 f803    wait              63492
    01a6  4050 f803    wait              63492
    01a7  4050 f803    wait              63492
    01a8  4050 f803    wait              63492
    01a9  4050 f803    wait              63492

     

    I cannot understand what they means:

    1) no operation 63491, 63490, and 63489

    2) the number of waits and the value 63492

    3) The hexadecimal number F803 is 63491 in decimal, why is 1 added?

     

    I'm sorry for disturbing you due to our solution and my curiosity.

     

    Thanks,

    Eunsang Ko

  • Hi Eunsang,

    The sequences were created, they should be posted soon. In general, we don't allow customers to generate MBMC sequences due to the complexity and we would like to help prevent any issues that might arise.

    -Paul
  • Hi Paul,

    How is it going?

    Could you build MBMC sequences with different exposure time?

    1) 1 * 1bpp red + 1 * 1bpp green + 22 * 1bpp blue with 1725 uSec exposure (Trig. Period >= 2200)

    2) 1 * 1bpp red + 1 * 1bpp green + 22 * 1bpp blue with 2000 uSec exposure (Trig. Period >= 2475)

     

    Thanks,

    Eunsang Ko

  • Hi Eunsang,

    The sequences have been created and posted. You should see them within 24 hours.

    Thanks!
    Paul
  • Hi Paul,

    May I ask a complicate question?

    I use MBMC sequence with the LC3000 projector.

    If I use the 14 patterns MBMC sequence, should I update or modify FPGA?

    ( I cannot modify the number of patterns: 24 in GUI, it is always disabled when MBMC is enabled.)

    At this time, I have used (requested) the 24 patterns MBMC sequence.

    But, I use only 14 patterns after grabbing 24 images due to trigger signal. (I throw 10 images away)

    Thank you.

    Eunsang Ko

  • Eunsang,

    Are you asking if it is possible to get a 14 pattern MBMC sequence? I would have to take a look at this next week when I have my Lightcrafter unit with me.

    If you could clarify your question that would be helpful.

    Thank you,
    Paul
  • I mean that...
    After 14 patterns(1r 1g 12b) are displayed (14 triggers are generated), is it possible to display next pattern(1r) without delay?
    (now, 10 * exposure times are delayed because the "24 images" in one cycle is fixed.)

  • Okay, thank you. I will investigate this. It should be possible to set an MBMC sequence to your desired length, but I'll need some time to confirm this.

    -Paul
  • Eusang,

    I believe that the 24 images is fixed because up until this point you've asked for patterns which are 24 bit planes. Would you like a 14 image sequence? Just let me know what settings you need and we can try it out. What you mentioned above (1r 1g 12b) should work to give you what you want.

    -Paul
