Phantom VS OpenALPR integration

[khanfar]

does alternative version of OpenALPR called Phantom available ? and how to implement ?

[connervieira]

Phantom is a modified version of OpenALPR, designed to integrate more smoothly with Predator. Predator is capable of using both Phantom and OpenALPR.

The installation process for Predator is described in the DOCUMENTATION.md file. The installation process for Phantom is documented in it's respective DOCUMENTATION.md file as well.

[khanfar]

Give me github link for that

[connervieira]

All documentation is bundled with Predator. You can find step by step installation instructions for all dependencies, including Phantom in the DOCUMENTATION.md file, as described above.

Thanks

i do all requirenments setup then try run i got this error : python3 main.py Loading Predator... Traceback (most recent call last): File "/home/pi/Predator/main.py", line 46, in import utils # Import the utils.py scripts. File "/home/pi/Predator/utils.py", line 89, in import cv2 # Import OpenCV ModuleNotFoundError: No module named 'cv2' pi@raspberrypi:~/Predator $

i do this sudo apt install python3-opencv then i try gain then i got this error : python3 main.py Loading Predator...

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy C-extensions failed. This error can happen for many reasons, often due to issues with your setup or how NumPy was installed.

We have compiled some common reasons and troubleshooting tips at:

https://numpy.org/devdocs/user/troubleshooting-importerror.html

Please note and check the following:

• The Python version is: Python3.9 from "/usr/bin/python3"
• The NumPy version is: "1.23.5"

and make sure that they are the versions you expect. Please carefully study the documentation linked above for further help.

Original error was: libcblas.so.3: cannot open shared object file: No such file or directory

It looks like you skipped a section in the installation instructions.

In step 1, you'll find instructions on how to install several dependencies of Predator. If you don't need OpenCV functionality, that section also explains how to disable it so Predator can be used without it.

ok , now i got this : python3 main.py Loading Predator... Traceback (most recent call last): File "/home/pi/Predator/main.py", line 46, in import utils # Import the utils.py scripts. File "/home/pi/Predator/utils.py", line 180, in plate_file = open(plate_file_location, "r") # Open the plate log file for reading. FileNotFoundError: [Errno 2] No such file or directory: '/home/cvieira/Software/Support/Predator/Interface//plates.json'

[connervieira]

Please make sure you complete the step by step installation instructions. You're receiving that error because you didn't complete the configuration section in the documentation.

[khanfar]

ok , i wil look but can it read live feed from external camera connected to usb port with raspberry ? like xbox kinect camera ?

[connervieira]

Predator can interface with USB cameras that are supported by FSWebcam. An Xbox Kinect camera is unlikely to work due to its proprietary nature. In any case, an Xbox Kinect camera is highly unlikely to perform well for ALPR, since it's primarily designed for motion capture, and won't have a lens that's ideal for license plate reading.

here need to change the directory ? and create json ?

[connervieira]

The instructions for configuring Predator can be found in the documentation. Please follow the step by step instructions.

this correct ?

[khanfar]

i read but cant find were need to edit sorry english language not main language

[connervieira]

The documentation file links to the CONFIGURATION.md file. This file contains instructions for each configuration value, and how to set values in the config.json file

You're receiving errors because you haven't completed the installation. Please follow the installation instructions found in DOCUMENTATION.md before attempting to run Predator. Once you reach the "Usage" section in the installation instructions, you can start using Predator.
