bb_raspicam

python code for automatic feeder and hive entrance cams. automatically detects bees and stores short videos to be decoded by bb_pipeline

Raspberry Pi install:

RPi OS and options

• Download and install Raspberry Pi Imager on your computer.
• Enable SSH and hostname identification in the install options. Note the hostname (e.g. 'exitcam0' - this can then be used to connect via ssh on the local network)
• Flash the OS with appropriate version to the SD card

On RPi:

Clone repo and run install script:

git clone https://github.com/BioroboticsLab/bb_raspicam.git
cd bb_raspicam
bash setup_raspicam.sh

Enable camera and restart

sudo raspi-config

-- Go to ‘Interfacing options’ and enable camera. -- reboot

Check that the date/time is correct:

date --iso-8601=ns

Setup SSH key for server

ssh-keygen -t rsa -b 2048
ssh-copy-id pi@SERVERNAME

Create user_config.py file for file transfer:

cd bb_imgstorage_nfs
vim user_config.py

Fill in settings

Edit config files

Update local copies of exitcam.cfg or feedercam.cfg with appropriate device number and settings

Workflow on RPi

1. Connect to Rpi via SSH and verify the time is updated. Example if the RPi is named 'exitcam0'

ssh pi@exitcam0.local
date --iso-8601=ns

2. If needed - connect to VPN network

sudo openconnect -u USERNAME -b vpn.fu-berlin.de

3. Start camera program on RPi. Use either exitcam.cfg or feedercam.cfg as input

tmux new -s cam
cd bb_raspicam
## Exitcam:
python3 raspicam.py exitcam.cfg 
## Feedercam:
python3 raspicam.py feedercam.cfg 

4. Start file transfer on RPi

tmux new -s txfr
cd bb_imgstorage_nfs
python imgstorage.py

Auto-start configuration

Use the included script to setup raspicam and imgstorage as system services that start automatically when the RPi is restarted:

# Usage: setup_autostart.sh /path/to/bb_raspicam raspicam_cfg_filename /path/to/bb_imgstorage_nfs
# Example:
bash setup_autostart.sh /home/pi/bb_raspicam exitcam.cfg /home/pi/bb_imgstorage_nfs

Reboot and then both will start automatically
