Boson 640 MIPI M0153 16-bit

mkriesel

Thanks for looking into this. At the moment there aren't any plans using the sync pin but we are trying to see if this is something worth looking into.

Back to testing, I recently got the boson board in and am trying to test it but have run into an issue with trying to get the camera-server installed.

I'm getting
voxl-camera-server depends on libmodal-pipe (>= 2.14.0); however:
Version of libmodal-pipe on system is 2.13.2.

Then for libmodal-pipe 2.14.0
dpkg: regarding libmodal-pipe_2.14.0_arm64.deb containing libmodal-pipe:
libmodal-pipe conflicts with voxl-cpu-monitor (<< 0.7.0)
voxl-cpu-monitor (version 0.6.0) is present and installed.

Bu voxl-cpu-monitor 0.7.0
dpkg: regarding voxl-cpu-monitor_0.7.0_arm64.deb containing voxl-cpu-monitor:
voxl-cpu-monitor conflicts with libmodal-pipe (<< 2.14.0)
libmodal-pipe (version 2.13.2) is present and installed.

So I'm stuck in a bit of a circle with the libmodal-pipe if you could help out

Alex Kushleyev

@mkriesel , oh yeah, i now that dpkg stuck issue..

use dpkg --force-all -i <package.deb> , you can install voxl-cpu-monitor and libmodal-pipe together or separately.

Alright, I've tried a few things and I can't see to get things to work.

I copied the drivers into /usr/lib/camera/ and both the 8 bit and 14 bit drivers you provided gave the same error running various combinations of the set and read python scripts you sent.

Let me know if it seemed like I did something wrong, I tried both the J6 and J7 ports on the voxl 2 mini with the corresponding numbered driver.

Please make sure that you only have one sensormodule file for boson for the given configuration in /usr/lib/camera/.

One thing to check is to see if the Boson is in active mipi state by default. You can add this to your boson_read.py file :

print('dvoGetMipiStartState: ')
result, mipi_start_state = myCam.dvoGetMipiStartState()
print(result)
print(mipi_start_state)

print('dvoGetMipiState: ')
result, mipi_state = myCam.dvoGetMipiState()
print(result)
print(mipi_state)

My output is:

dvoGetMipiStartState: 
FLR_RESULT.R_SUCCESS
FLR_DVO_MIPI_STATE_E.FLR_DVO_MIPI_STATE_ACTIVE
dvoGetMipiState: 
FLR_RESULT.R_SUCCESS
FLR_DVO_MIPI_STATE_E.FLR_DVO_MIPI_STATE_ACTIVE

FLR_DVO_MIPI_STATE_ACTIVE is 2, FLR_DVO_MIPI_STATE_OFF is 0

If your sensor does not show active start state, then it may need to be set using the following:

myCam.dvoSetMipiStartState(FLR_DVO_MIPI_STATE_E.FLR_DVO_MIPI_STATE_ACTIVE)

If this still does not work, it is possible that my script does not do the full setup for mipi output, so you may want to try using the FLIR GUI for the initial setup (for 8 bit post AGC and use the default 8 bit sensormodule): https://docs.modalai.com/M0153/#boson-software-setup

@mkriesel , I have updated the boson configuration and read scripts (boson_read.py, boson_set_8bit.py, etc) to include configuring additional settings like mipi start state, dvo output interface, etc. Please download them again (from links earlier in this thread) and try again. Also, just to confirm that the original Boson setup instruction using the FLIR GUI should work for 8 bit format.

Just one note, even though I set myCam.dvoSetOutputFormat(FLR_DVO_OUTPUT_FORMAT_E.FLR_DVO_IR16), where FLR_DVO_IR16 = 3, when i read back the configuration, i get the default format (2) : FLR_DVO_OUTPUT_FORMAT_E.FLR_DVO_DEFAULT_FORMAT = 2 . It seems that in your output the ouput format is set to 3 - i am not sure why, there could be some minor quirks in the boson firmware.

In any case, please try the GUI and updated scripts and let me know how it goes!

@Alex-Kushleyev It seems to be working now, I'll do more testing but this looks correct

| Pipe Name | bytes | wide | hgt |exp(ms)| gain | frame id |latency(ms)| fps | mbps | format
| boson | 327680 | 640 | 512 | 0.00 | 799 | 163 | 21.6 | 60.0 | 157.3 | RAW8
| boson_bayer | 655360 | 640 | 512 | 0.00 | 0 | 163 | 20.0 | 60.0 | 314.6 | RAW16
| boson_color | 983040 | 640 | 512 | 0.00 | 799 | 163 | 22.7 | 60.0 | 471.9 | RGB
| boson_misp_encoded | 8826 | 640 | 512 | 0.00 | 799 | 163 | 25.5 | 60.0 | 4.1 | H265 (P)

Thanks for the help! Also, what version of the bosonSDK are you using for your python scripts? My version (3.0) doesn't have the dvoSetMipiStartState and a few other functions and I can't find a higher version on their website?

Alex Kushleyev

@mkriesel , I am glad that you got it working! You should also be able to view the boson output in voxl-portal -- for the 14 bit case, there is a very simple re-scaling done from 14 to 8 bit, just for testing (WIP).

I am using SDK4.0_Boson_Plus_SDK. You should probably contact Flir to get access to it, since we can't distribute it.

I'm trying to pull the images off and they seem to be corrupted somewhat. It almost seems like I'm getting the 16 bit image but in an 8 bit format. I'm subscribing to the boson_bayer and the image I'm getting seems to be the correct size and length but when I save its not correct. The RAW 8 stream I get on the voxl-portal looks the same, which I would expect for testing.

Heres what I'm getting for reference
https://drive.google.com/file/d/1fG5XEPM-b1NbC6H9R4jWSvZTDxm-a6Y_/view?usp=sharing

And then code I'm using to save it

static void _frame_cb(__attribute__((unused)) int ch, camera_image_metadata_t meta, char* frame, void* context)
{

    CameraInterface* interface = (CameraInterface*)context;

    if (interface->GetState() != ST_RUNNING) {
        return;
    }

    if (interface->ShouldSkip()) {
        return;
    }

    if (meta.format == IMAGE_FORMAT_NV12) {

    }
    else if (meta.format == IMAGE_FORMAT_RAW8) {
     
    }
    else if (meta.format == IMAGE_FORMAT_RAW10) {

    }
    else if (meta.format == IMAGE_FORMAT_RAW16) {
        std::cout << "16 bit image " << meta.size_bytes << " stride " << meta.stride << std::endl;
        int input_height = meta.height;
        int input_width  = meta.width;

        size_t frame_size = input_width * input_height * 2;

        char outname[100];

        std::string image_folder_name = "/data/pgm_frames";

        // uint16_t* frame_data = reinterpret_cast<uint16_t*>(frame);

        sprintf(outname, "%s/frame_%06lu.pgm", image_folder_name.c_str(), meta.timestamp_ns);
        printf("Output filename: %s\n", outname);

        // out_image.write(reinterpret_cast<char*>(pixels), IMAGE_PIXELS * sizeof(uint16_t));
        std::ofstream out_image(outname, std::ios::binary | std::ios::out);

        out_image << "P5\n640 512 65535\n";
        out_image.write(frame, frame_size);

    }
    else {
        // Not implemented
        std::cout << "other" << std::endl;
    }
}

Any thoughts?

Alex Kushleyev

@mkriesel , it looks like potentially an little vs big endian issue when using PGM - can you try to swap the byte order?

save image on voxl:

voxl-record-raw-image boson640_bayer -n 1 -d ./

display image using python3:

import cv2
import numpy as np

WIDTH  = 640
HEIGHT = 512
FILENAME = "boson640_bayer_640x512.gray"

# read 16-bit file
img = np.fromfile(FILENAME, dtype=np.uint16).reshape(HEIGHT, WIDTH)

# simple normalize
vmin     = np.min(img)
vmax     = np.max(img)
img_8bit = cv2.convertScaleAbs(img-vmin, alpha=255.0/(vmax-vmin))

# show image
cv2.imshow("Normalized Image", img_8bit)
cv2.waitKey(3000)
cv2.destroyAllWindows()
