Camera version is being detected as 1.13 even though I have Raspberry Pi Camera v2.1

[npaibrooklyn]

Hello @pageauc I just noticed that pi-timolo is detecting the camera version as 1.13 even though I have connected a 2.1 version of camera (https://www.raspberrypi.org/products/camera-module-v2/).

This is what I am seeing on the console: 2021-04-22 16:23:09 INFO Pi Camera Module is Enabled and Connected supported=1 detected=1 2021-04-22 16:23:09 INFO picamera version is 1.13

As a result, I am not able to use the max resolution (3280 × 2464 pixels) and it is rounding it off to (2592 × 1944 pixels)

Looks like the version is detected thusly: picameraVer = require('picamera')[0].version

Is it merely looking at the python picamera module's version?

Some more info:

$ pip freeze | grep picamera picamera==1.13

Perhaps I need to just upgrade the module?

@pageauc doesn't look like there is a 2.X version of the python picamera module. Perhaps we need a different way of detecting the camera version rather than rely on the python module version?

@pageauc I think I have a possible fix. I tested it and it works. Please feel free to take this for your repo and alter it as you wish, if you like the fix:

After some work I found a cludge for checking the maximum resolution of the attached picamera module hardware

This is the code i wrote based on some forum threads

import os

print('Checking Pi Camera Module version Wait ...') os.system('/usr/bin/raspistill -o ./image.jpg')

from PIL import Image from PIL.ExifTags import TAGS img = Image.open('./image.jpg') exif_data = img._getexif() for tag, value in exif_data.items(): if TAGS.get(tag, tag) == 'ImageWidth': imageWidth = value if value >= 3280: print('Max ImageWidth is %i PiCamera module hardware is ver 2' % value)

print TAGS.get(tag, tag), value

os.remove('./image.jpg')

This works under python2 and 3 and uses raspistill to take an image, then exif data fow imageWidth is used to determine the max resolution width of the attached picamera module. Note this does not check for a ver1 camera module. but could just add else

Would like a more elegant way to check the camera hardware version. Looks like the require method fails.

I will look at updating pi-timolo to use the above method to check for the camera module hardware version

I have updated pi-timolo.py to ver 12.07 that now uses raspistill and exif data to determine what hardware version of pi camera is installed Please run menubox.sh UPGRADE option and test. Let me know results Thanks Claude ....

Hey @pageauc instead of creating an image and checking its property (which as you pointed out is not elegant) you can use the method that pycamera python module supplies. I have shown it in https://github.com/npaibrooklyn/bird-brain/commit/f9a3cb8ddd01f5e014c4f5b1f41b2f03306497b0

[npaibrooklyn]

with picamera.PiCamera() as cam:
        CAM_MAX_RESOLUTION = cam.MAX_RESOLUTION
        logging.info("Cam max resolution is %s", CAM_MAX_RESOLUTION)
        CAM_MAX_WIDTH, CAM_MAX_HEIGHT = CAM_MAX_RESOLUTION.width, CAM_MAX_RESOLUTION.height
        logging.info("Cam max width is %s, Cam max height is %s", CAM_MAX_WIDTH ,CAM_MAX_HEIGHT)

is the code block to get the max width and max height directly from the camera. Pls refer to https://github.com/npaibrooklyn/bird-brain/commit/f9a3cb8ddd01f5e014c4f5b1f41b2f03306497b0

@pageauc if you wish, you can give me collaborator access to your repo and I can submit the fix above in a PR for your review. I believe it is more elegant and faster than writing and image and checking its property. Or you can just copy the changes from https://github.com/npaibrooklyn/bird-brain/commit/f9a3cb8ddd01f5e014c4f5b1f41b2f03306497b0

[npaibrooklyn]

Thanks for making the fix @pageauc . Just one more thing: we can get rid of setting picameraVer variable to 1 or 2 and remove its usages. We have the resolution of the camera so we can just that directly. You can see the changes in https://github.com/npaibrooklyn/bird-brain/commit/f9a3cb8ddd01f5e014c4f5b1f41b2f03306497b0

The relevant block is pasted here as well.

# Round image resolution to avoid picamera errors
image_width = (IMAGE_WIDTH + 31) // 32 * 32
if image_width > CAM_MAX_WIDTH:
    image_width = CAM_MAX_WIDTH
logging.info("Using image width %s", image_width)

image_height = (IMAGE_HEIGHT + 15) // 16 * 16
if image_height > CAM_MAX_HEIGHT:
    image_height = CAM_MAX_HEIGHT
logging.info("Using image height %s", image_height)

stream_width = (STREAM_WIDTH + 31) // 32 * 32
if stream_width > CAM_MAX_WIDTH:
    stream_width = CAM_MAX_WIDTH
logging.info("Using stream width %s", stream_width)

stream_height = (STREAM_HEIGHT + 15) // 16 * 16
if stream_height > CAM_MAX_HEIGHT:
    stream_height = CAM_MAX_HEIGHT
logging.info("Using stream height %s", stream_height)

The logic is used to round camera image settings to even 32 pixel blocks. For the moment I will leave current logic since it works OK and is only done during initial checks Thanks Claude ...
