CASP Tutorial-4 Project

This tutorial demonstrates how to do basic hardware interfacing with webcam.

Pre-Requisites

· Tutorial-2 should be completed.

Model

· Network Camera block is used to capture video images. The output of camera is passed through edge detector filter.

· Original image along with edge detection image is displayed in separate sub-windows in simulation panel.

Step 1: Create New Project

· Follow steps mentioned in Tutorial-2.

Step 2: Select Target Hardware

· Follow steps mentioned in Tutorial-2.

Step 3: Creating Model

· Create a model as shown in below figure.

· To access camera connected to USB port, set camera address as 0. For a network camera set relevant URL of camera video stream.

· Leave image configuration parameters in camera and edge detector blocks to defaults.

· Configure edge detector block execution during Simulation Plot Step.

· Give names to image viewer blocks shown in below figure.

· Configure simulation panel and map image viewer blocks to simulation panel sub-windows as explained in Tutorial-2.

Step 4: Setup Simulation Parameters

· Set simulation time step to 1000msec and plot step to 10000msec.

· Rest of the parameters shall be set as mentioned in Tutorial-2.

Step 5: Run Simulation

· Press Build/Run button from Home->Simulation menu item. CASP builds and compiles the model and opens separate simulation panel window. In the simulation panel window press ‘Run Simulation’ button to run simulation.

· The output of image blocks are shown below.
