Abstract—RANSAC (Random Sample Consensus) can be used as mathematical model parameters of a set of observed data contains inlier and outlier data. In manufacture can also be used to build exact line equations from a number of data, by validating the data by looking at the inlier and outlier data of a project being worked on. To create a program in making this final project, the author uses two-dimensional data that is processed by LiDAR (Light Detection and Ranging), the author conducts data collection and research on the performance of two-dimensional object reconstruction using RANSAC modifications in Python. In the first experiment using data from LiDAR detection, the authors limit that the variable value of the residual threshold is above 3000, so it can be expressed as an imperfect image, from the first test it is produced with 92.85% perfect data, while for the second test it gets 52% data. Perfect. Reconstruction of 2D objects from LiDAR data can be validated using the RANSAC method. Ransac method is used to build the exact equation of the line from a number of data. So that the generated line can be a reference whether the amount of data to be observed is a correct 2-dimensional object reconstruction. How to validate by looking at the suitability of the inlier and outlier data from the RANSAC line equation. Inliers data will indicate whether the pattern of the reconstruction data is appropriate.

Abstract

Selama beberapa waktu terakhir, pengembangan sistem deteksi objek berbasis LiDAR telah menjadi fokus utama bagi para pengembang kendaraan listrik otonom. Banyak upaya telah dilakukan untuk meningkatkan dan mengoptimalkan teknologi ini guna mencapai mobilitas otonom yang lebih canggih dan aman. Begitu pula yang dilakukan oleh BRIN, Pengembangan sistem deteksi objek berbasis LiDAR telah berhasil dilakukan hingga rekonstruksi dan posisi objek dapat ditemukan. Namun demikian pemanfaatannya belum mencakup sistem safety dan guidance dalam hal ini mengendalikan gerak laju kendaraan, rem, dan kemudi. Untuk memaksimalkan hasil sistem pendeteksian objek berbasis LiDAR yang telah diperoleh sebelumnya, maka pada penelitian tugas akhir ini akan di kembangkan sistem tersebut sehingga dapat digunakan untuk mengkombinasikan kerja laju kendaraan, rem, dan kemudi secara otomatis. Sistem safety dan guidance ini dilakukan dengan mengembangkan metoda maneuver untuk menghindari objek yang pendekatannya dapat dilakukan berdasarkan metoda fuzzy mamdani. Adapun algoritma di kembangkan dengan menggunakan python pada Jetson AGX Xavier, sedangkan untuk memproses gerak kendali maneuver yang dihasilkan dilakukan pada Mikrokontroller Teensy 4.1. Sistem safety dan guidance ini telah diterapakan pada kendaraan listrik roda tiga sederhana, dan dapat membantu kendaraan tersebut dapat ber manuver menghindari objek di depannya hingga 5 meter.

Abstract

A wide field of vision is required for autonomous electric vehicles to operate object-detecting systems. By identifying objects, it is possible to imbue the car with human intelligence, similar to that of a driver, so that it can recognize items and make decisions to prevent collisions with them. Using a 360-degree camera is a wonderful idea because it can record events surrounding the car in a single shot. Nevertheless, 360º cameras produce naturally skewed images. To make the image appear normal but have a bigger capture area, it is required to normalize it. In this study, NVIDIA Jetson Nano is used to construct software for 360-degree image normalization processing using Python. To process an image in real-time, first choose the image shape mapping that can give information about the entire item that the camera collected. Then, choose and apply the mapping. Using Python on an NVIDIA Jetson Nano, the author of this research has successfully processed 360-degree images for local and real-time video as well as image geometry modifications.
