Getting Started

The Verilog files for out implementation are located in Sources along with the ESP32-CAM implementation.

The Xilinx IP and Vivado files are located in Vivado Files. Since we are using the Basys 3, make sure to use the correct directory. The Nexys implementation was used for simulation purposes. The hardware layout is given in a later section.

For a general understanding of this program, feel free to look at the presentation and the demo video.

Code To Look At

The image processing algorithm is located in Sources/Full Integration - Basys/houghAccumulator3.v or here.

Hardware

This project requires two pieces of hardware:

• FPGA
  • Basys 3 was used for implementation
  • Nexys A7 was used for testing but has a different constraint file.
• Camera
  • ESP32-CAM was used for the initial implementation
  • OV7670 is used for the current implementation

Peripherals

BRAM

All fully integrated modules use a BRAM IP, which may not transfer well when pulling this repo. For this reason, the following is an image of the IP block.

Licenses and Contributions

This project uses parts of the Xilinx IP.

This project is licensed here.

Video

The demo video is located here on Google Drive. You must have the correct access to get to it. Reach out to Andrew at agwoska@bu.edu or andrew@woska.org for access if needed.

Title: DetectoVision: Object Detection on FPGA

Description:

Known Problems

• The ESP32-CAM does not always take an uncorrupted image
