Format is here:

openmv/openmv/blob/master/src/omv/imlib/orb.c#L708


      
              // Fix rectangle w/h
              r->w = r->w - r->x;
              r->h = r->h - r->y;
          
          
    // Free distance array
              fb_free();
              return matches;
          }
          
          
#if defined(IMLIB_ENABLE_IMAGE_FILE_IO)
          int orb_save_descriptor(FIL *fp, array_t *kpts)
          {
              UINT bytes;
              FRESULT res;
          
          
    int kpts_size = array_length(kpts);
          
          
    // Write the number of keypoints
              res = f_write(fp, &kpts_size, sizeof(kpts_size), &bytes);
              if (res != FR_OK || bytes != sizeof(kpts_size)) {
                  goto error;
