Safety Evaluation of Autonomous Vehicles for a Comparative Study of Camera Image Distance Information and Dynamic Characteristics Measuring Equipment

Abstract

Currently, the stage of technological development for commercialization of autonomous driving level 3 has been achieved. However, the legal and institutional bases and traffic safety facilities for safe driving on actual roads in autonomous driving mode are insufficient. Therefore, in this study, a measurement method using a camera(monocular or dual) was used to evaluate autonomous vehicles. In addition, integrated scenarios was proposed wherein the scenarios proceeded continuously. The precision of the autonomous vehicle safety evaluation method using cameras was verified via comparisons and analyses with the results of real vehicle tests. As a result of the test, the difference in the average error rate of inter-vehicle distance between the monocular camera and the dual camera was 0.34%. The difference in the average error rate of the distance to the lane was 0.3 to 0.5%, showing similar results. It is judged that it will be possible to compensate for each other’s shortcomings if they are used at the same time rather than the independent use of monocular cameras and dual cameras.
