This is an example of using the shared memory interface to connect ImprovCV to an Automotive Simulator.
Simulation is a common prototyping technique for many automotive applications. ImprovCV can read from a shared memory location to perform image processing on other applications. In this example the lane detector is used to identify lanes, and the central lane and its midpoint are calculated. This data is fed into 4 different controllers (On/Off,P,PID,Fuzzy) and the simulated vehicle is driven to the central lane position. This demonstrates closed loop control with ImprovCV.^ top
This is an example of a simple hough-transform based lane tracking application.
Lane detection is an essential component of many intelligent vehicle applications, including Lane Following (LF), Lane Keeping Assistance (LKA), Lane Departure Warning (LDW), lateral control, Intelligent Cruise Control (ICC), Collision Warning (CW) and eventually autonomous vehicle guidance. The lane detection procedure can approximate the position and orientation of the vehicle within the lane, and can also provide a reference system for locating other vehicles or obstacles in the path of the one viewing the scene.
The lane detection example uses the following filters:
This example identifies vehicles from a monocular image using optical flow and edge detection. The cars, once detected, will be followed in consecutive images by a tracking system using a template matching technique. The procedure is done in four steps:
This example demonstrates stereo vision functionality.
As the distance information is very important for driver assistance, for example to warn the driver of possible collision, a second camera is often used. Initialy the cameras fundamental matrix is calculated using RANSAC. The images are then rectified, and a correspondence search is performed and the distance is found using the similar triangles theorem.Three different methods for analyzing stereo images in order to find correspondences are shown. Right, the distances estimated to a car, plotted on the car rear.
