Abstract

Image processing combine with machine learning is used widely in image recognition, image classification, and image detection. By using camera to detect an object has been done within several article by Guamán & Naranjo and Shah S.P.. The other usage of image and object detection is in measurement of distance. Distance measurement is possible by using additional peripheral such as sensor and extra camera. In previous research by S.H.Chen, detecting an object by knowing focal length of camera and object using spatial dan disperse technic can produce error percentage of max 5.72%, and deviation of 0.79. The distance used is in meter. Thus the deviation is in 79cm. This research is intended to elaborate the usage of single camera in detecting and measuring distance without using any sensor and can be used without knowing the focal length of a camera. The distance to be measured is between the camera and the object. In this research, author used a square object with different size and different distance range. By using one of the known data as a pivot in calculating other image distance, the average error between 4%-7% . These result was achieved by using different object size. The bigger the size of the object used as reference, the smaller the error percentage of the measurement.
