Image processing - Do you have any good ideas?  
car license plate correction

hello. Thank you for your interest in my writing.

Please refer to the picture.  
The license plate is trapezoid-shaped. It is actually rectangular in shape.  
However, the ‘CCTV’ has a ‘trapezoid’ shape in the direction it is facing.

I want to make this into a ‘rectangle’ in software.  
Do you have any good ideas? Or is there an easy solution?

`FILTER_2.copy(FILTER_1, 40*i, round(0.2*parameter_h*i) ,40,400-round(0.9*parameter_h*i), p_x,0,round(1.2*p_w_n),400);`

This was solved using the copy function.
