Title: SENSOR FOR AUTOMATIC DRIVE
Abstract:
A sensor for automatic drive, wherein at least one linear laser emission device (1) facing the ground in front is arranged on a vehicle, and at least one digital imaging module (2) is arranged on a part of the front portion of the vehicle which is lower than or higher than the linear laser emission device (1); the digital imaging module (2) is mainly used for taking in projection lines of linear laser rays at a projection position in front of the vehicle on CCD or CMOS photosensitive elements of the imaging module (2), and whether the projection lines of the laser rays on the ground are blocked by obstacles or not may be determined according to the positions and shapes of the laser rays on the photosensitive elements. Optical sources of the linear laser emission devices are point-like laser emitters (12) or small, wide-angle word line laser emitters (11), which may not only prolong a word line, but also may improve the brightness of a linear laser.
