Vehicle Detection

A simple C# vehicle detection from EmguCV library on console application.

Solution

Image processing for vehicle and find by feature extraction that appear in realtime viedo stream in fast performance technical.

• Reduce the size of frame by gaussian pyramid down.
• Noise reduction processing in blur feature.
• Background subtraction by CNT algorithms (outdoor light resilient).
• Detect the vehicle aligment in partial frame or detection zone with contours processing.

Requirement

1. Visual Studio 2017
2. Nuget Emgu.CV 3.4.3.3016 and dependency ZedGraph 5.1.7

Using

The core of Engine class can be set the camera usb port in index (0 base index have the default value) or choose the video file play.

int cameraUSBPort = 0;
var engine = new Engine(cameraUSBPort);

In the video player mode can be set the video file parameter.

string videoFilename = <videoPathFilename>;
var engine = new Engine(videoFilename);

To run the engine use the Run() method and set the vehicle detection object class.

// Detect in full frame.
engine.Run(new TrafficVehicleDetection());

// If you want to spec in zone detection. It can be set to scale rectangle zone in 0.0-1.0 value.
// In this example we have to scale for rectangle detection in bottom half frame.
engine.Run(new TrafficVehicleDetection() {
    DetectionScale = new System.Drawing.RectangleF(0.0f, 0.5f, 1.0f, 0.5f)
});

To exit program use Esc key.

Output

Find object by feature extraction.

Detection zone and output.
