History of ADA51999-2001Stereo image sensor- Adaptive cruise control- VDC preview control- Vehicle distance warning- Lane departure warning- Corner entering speed warning & control2003 -Stereo image sensor andmillimeter radar were mountedto assist driving under allweather conditions2006 -Full speed range adaptivecruise control by laser radar
Principles of Stereo Camera 16(1) TriangulationNew point CKnownpoint BKnownpoint A- Triangulation is a surveying method that a positional relation between anew point and known points can be obtained by measuring angles from twopoints (Known points A, B)of which positions are already known to a point tobe measured (New point C).- Position accuracy and angle accuracy of know points A and B determinedistance accuracy.3 / 15
