Object detection and calculation OPENCV

The main objective of the solution is to install a camera in front of a tramway which will have the below objectives:

*Follow the rails in front of the driver
*Detect intruding objects (People, cars, motorbikes, etc.)
*Calculate the number of detected objects by type ( number of cars, number of people... )
*Play an audible and visual alert to notify the driver
*Record videos with objects recognition (24 hours a day) on an external hard drive and send them to cloud / ftp afterwards when the WIFI connection is available.
*Video clips that contain alerts must be saved in separate files with 2 minutes before and two minutes after ( the two minutes can be changed, so need to be parameter )


the Hardware / Software architecture used is not exhaustive; we suggest using the components below:

*Raspberry-Pi 3B or Orange-PI or Banana-PI
*Extensive SATA card: https://aliexpress.com/item/32813330952.html
*Infrared Night Camera: https://aliexpress.com/item/1005002624944587.html
*Speaker
*Screen: https://aliexpress.com/item/1005002542127944.html

But you are free to use any other hardware that can help like HUSKYLENS AI for example: https://aliexpress.com/item/4000762406956.html

For Software you can use any library you see that it'll be helpful (Yolo, Transflow ...) and you also have multiple OS that can help for standard CCTV / NVR features (Shinobi, motioneyeos ...)
