Calibration | Need Guidance

[Cătă Tibori]

I installed openalpr on a Raspbian. Test went ok but now I'm trying to calibrate camera in order to see plate number. 

What I did

1. sudo apt update 

2. sudo apt install openalpr-utils

-> No errors

3. root@project:/# ./openalpr-utils-calibrate camera_image.jpg

bash: ./openalpr-utils-calibrate: No such file or directory

Here I'm stucked!

a. What can I do further?

b. Where should I copy the output values of the calibration?

In openalpr I have the following files

root@stagingtm:/openalpr/config# ls

alprd.conf.defaults  alprd.conf.user  openalpr.conf.defaults  openalpr.conf.user
