Abstract

Height measurement is important in the field of health, athletics, and others. During this process the measurement height is done manually by using the tools in the form of tape measure or ruler. This takes quite a long time. With the weaknesses of such height measurements, then on this research designed a height measurement system based on Digital Image Processing Techniques. The parameters used for this research is the distance of the camera, the height of the camera, the camera angle, the color of the shirt, and the position of the object. Testing is done by performing processing and digital image analysis. By using these techniques, it only takes 35 seconds to process measurement and results. In addition to the test results can be stored in the system database, making it easier for data archiving. Of the overall testing with parameters of the camera distance, the height of the camera, the camera angle, the color of the shirt, and the position of the object, resulting in a measurement of the height of a more objective and accurate with the level of accuracy of 99.5%.

Summary

Introduction

Many of the problems that require image as input or the input of the system due to the limitations of the human being in terms of processing speed, efficiency, and other factors. One of the systems that need the image as input is on the process of measuring the height of the people. Height measurement to date is still often done manually[1]. This process takes relatively long ranges from 2 minutes to the measurement and recording of results. One of the techniques used to measure height with the RGB image conversion process image to HSV[7,8], calculate the distance the minimum up to HSV until HSV maximum, process of thresholding erosion and dilation, after which the process of smoothing, and look for the point of the contour and point coordinates that will be calculated into the results of the measurements of height. For the process of shooting back and forth transfer processes performed on the camera to determine the angles and count high with special beam method on the lens[9]
