Lesson Background HTML
Automated vehicle (AV) camera technology can detect and extrapolate location of lane markings and identify a wide variety of MUTCD traffic signage at vehicle speeds of up to 155 mi/h, with lateral offsets up to approximately 60 feet and at heights up to approximately 20 feet dependent on light levels and weather conditions (e.g. fog, snow, rain). Current AV camera systems can compare and process a visual field (1 to 2 mega pixels) up to 35 times per second. Delta information can be used to estimate movement and paths of other objects e.g. pedestrian approaching roadway. Vision software requires an object to have a minimum number of pixels width for recognition (typically around 20). Newer systems continue to improve frame rates for faster detection of objects (e.g. signs) and lane markings, and faster calculation of desired vehicle paths.
The following ADAS applications are enabled by AV camera technology:
- Lane Departure Warning
- Lane Keeping Assist
- Distance Warning
- Pre-crash Vehicle Preparation
- Collision Warning
- Automatic Emergency Braking
- Basic Adaptive Cruise Control
- Traffic Sign Recognition
- Auto Head Lamp (on/off)
- High Beam Control.
