# **FPGA camera inverse perspective mapping (Bird's-eye view)**
|
|
Using two **OV7670** cameras and *Digilent Basys3* board with *Xilinx Artix 7* series **FPGA** performing inverse perspective image mapping and displays result on **VGA** monitor.
|
|
|
|
A working model was created using **Verilog** HDL. This model is capable of setting up multiple cameras, as well as receiving videos from them. Received image before saving can be transformed into a black and white image or transformed using transformation matrices.

# Result
|
|
|
|
Original image from camera
|
|
|
|
|
|
|
|
After uploading the configuration to FPGA board in the corner of the monitor, You can see chessboard without perspective
