Research on Split-Field Monocular Stereo Cameras Using Mirrors
For an advanced driver assistance system (ADAS) that automatically controls and operates the vehicle system in order to realize a safe and secure society in which vehicles and people coexist, the authors examined a method to realize stereo vision with an inexpensive configuration in a monocular camera. Generally, a monocular camera can construct an ADAS system at low cost, but there is a problem in terms of distance measurement accuracy. On the other hand, a stereo camera that can measure the distance using two monocular cameras with the same mechanism as the human eye has high distance measurement performance, which is advantageous for the sophistication of the ADAS system, but the cost increases. It becomes an issue. Therefore, in this research, the authors investigated an inexpensive stereo camera and devised a method to realize stereoscopic vision by dividing the field of view of a monocular camera using two reflective mirrors with different postures. They built a prototype and evaluated this method, demonstrating that it can measure a distance of 30 m with an error of 12%.
