Power Rating of StereoPi

What should be the input voltage and current rating of StereoPi so that every component(2 camera, mouse, keyboard, Compute Module) will work properly?

You can consider StereoPi as a regular Raspberry Pi 3B+ for power consumption.
Here is official Raspberry Pi power notice.
For RPi 3B+ it is recommended to use 5V power adapter, able to provide up to 2.5A

Some facts:
1. In most of our experiments StereoPi + Compute Module + two cameras + WiFi dongle (not high power) consumption within 1-1.5A.
2. In our code we did not use full power of GPU. So if you use a very specific code to provide 100% load for ARM kernels, GPU, USB and Ethernet, you can theoretically need ~2.5A

I'd recommend you to use 2.0A and more power source, and your StereoPi will be happy.

Thank you so much Sir
The issue has been resolved, it was a power issue.
