Object distance determination application using image processing is develop to determine the distance of an object in a pair of 2D images using pair stereo vision. This application is develop based on the human vision feature that not commonly applied in automotive and mobile robotic fields nowadays.Therefore this project is carried out to build a prototype to determine the distance of an object in 2D image and identify the image processing technique for determine object distance.Rapid application development is applied as a guidance of development and the flow design of this application consist of four steps which is image acquisition,image filtering and enhancement,feature extraction and object detection and the last step is output calculation.The formula of output is generating base on the linear graph with linear equation y = mx + c.The tools that use to develop this application are visual c++ with opencv library as engine and MFC as application interface. The testing of the application is using 100 samples with different object and environment.The average error rate is about ±2.93 % after testing phases.The application is giving benefit to car manufacturer and mobile robotic manufacturer to enhance their automation function and increase the reliability.
