ALGORITMA BLOB dan FAST CORNER DETECTION PADA APLIKASI BANGUN RUANG MATEMATIKA BERBASIS MIXED REALITY

Abstract

The subject matter of Building Space at Elementary School (SD) mathematics will introduce shapes, calculation formulas, and their application in everyday life. The current digital era has many technologies that aim to make it easier for someone to provide solutions to the root of the problem. One of the technologies used in this research is Augmented Reality (AR) and Virtual Reality (VR) or known as Mixed Reality (MR). These two technologies will integrate with each other to solve problems in mathematics subject matter, namely Build Space. The purpose of this study is to introduce visualization of 2D to 3D space and support audio to increase user attractiveness by using the Blob Detection Algorithm and FAST Corner Detection, namely by detecting points or areas in the form of color, and angle detection will be carried out by FAST Corner Detection.. The test results are supported by a marker rating that can be read by several android devices. The test results for the response time are that the object will appear within <2 seconds, the camera tilt test results produce an angle value of <180 then the marker is not read on all devices and will has a perfect value at an angle of 60 0-90 0 , and the results of the distance test of the camera to the marker can be obtained from 30-100 cm so that the marker is detected by all cameras.
