2. Introduction THE NEED OF EFFICIENT SPEED MEASUREMENT RADAR GUN AND RADAR DETECTOR. MEASURING SPEED USING CCTV CAMERA 2

3. DOPPLER EFFECT FREQUENCY CHANGE DUE TO RELATIVE MOVEMENT OF SOURCE Frequency increases when source moves towards observer Frequency decreases when source moves away from observer 3

5. Detection of Vehicle 5

6. Reading the Video Feed and Frame Extraction Functions that will be used are videoinput,vision.videofilereader. 6

7. Detection of Vehicle The vehicle is detected as a separate silhouette in each video frame using gaussian mixture model 7

8. Gaussian Mixture Model A pixel in the frame is designated as a background or foreground using Gaussian PDF as a reference of the three colour components [R G B]. 8

9. Drawing The Bounding Box Bounding Box is drawn around the vehicle using functions like vision.BlobAnalysis 9

10. Coordinate Tracking Coordinate of bbox is tracked and placed in every frame using blob analysis 10

11. Camera Setup Distance Z between the vehicle and the vertical projection of the camera is calculated using trigonometry and optical geometry.. 11

12. Distance measurement Once the camera is setup, using trigonometrically relations we get the relationship between real word axis and optical axis.. 12

13. Distance measurement (cont.) Acc. to lens makers formula.. Therefore.. Since focal length of camera is few centimeters and distance Z is few metres, Z>>f. Hence f can be neglected in the denominator. 13

14. Distance Measurement(contd) Using the above formula we can find the vanishing points.. Where Uv & Vv are the vanishing points in the X & Y directions respectively Image plane 14

15. Distance measurement (cont.) Using the formulas discussed, we can derive 15

16. Calculation of speed… Speed= Distance calc in N frames *N ( frame rate) 16

17. ADVANTAGES Cost effective. Real time updates. Multiple vehicle tracking. Effective law enforcement. As surveillance cameras already installed no additional hardware required.` 17
