The automatic driving system comprises a capture unit, an acquisition unit, a data processing unit and an execution unit, wherein the capture unit is used for capturing the road condition information of the vehicle during running; the acquisition unit is used for acquiring the state information of the vehicle during running; the data processing unit is used for processing the road condition information and the state information of the vehicle; the execution unit is used for sending out commands to control the vehicle speed and the steering angles of the steering wheels. The automatic driving system and method, which are disclosed by the invention, are suitable for the technical field of automatic control of vehicles.

Automatic driving system and method of vehicle

The invention discloses a sensor for automatic drive. The sensor for the automatic drive is characterized in that a vehicle is provided with at least one linear laser emitting device 1, wherein the at least one linear laser emitting device faces to a forward ground; the position, which is lower than or higher than the linear laser emitting device, of the front of the vehicle is provided with at least one digital imaging module 2; the digital imaging module 2 is mainly used for shooting a projection line, at the forward projection position of the vehicle, of a linear laser ray 1 onto a CCD (Charge-Coupled Device) or CMOS (Complementary Metal Oxide Semiconductor) photosensitive element of the imaging module; according to the position shape, on the photosensitive element, of the laser ray, whether the projection line, on the ground, of the laser ray is shielded by an obstacle or not can be distinguished; the linear laser emitting device is that at least one punctuate laser emitting head or small-flare-angle straight-line laser emitting head makes a laser signal hit on a reflecting mirror 71 which swings to and fro at high speed; an arc line which is similar to a straight line is formed on a path through the reflection and the to-and-fro gyration of the reflecting mirror 71; a reflecting surface can be a plane surface or a curved surface; the brightness of the line can be guaranteed through forming a linear laser by the projection line obtained by using a method for making the laser signal hit on the gyrating cylindrical reflecting mirror by a laser head; a few of the laser emitting heads need to be mounted only.

The embodiment of the disclosure discloses an anti-collision method and apparatus, a range finding sensor and a terminal. First type distances between a target object and all range finding sensors arranged on a target obstacle are obtained and a second type distance between any two range finding sensors on the target obstacle is obtained; according to the first type distances and the second type distances, distance information between the target object and the target obstacle is obtained, wherein the distance information includes a distance between the target object and the target obstacle; when the distance information between the target object and the target obstacle meets a preset condition, an alarm signal is sent out, wherein the preset condition includes that the distance between the target object and the target obstacle is less than or equal to a preset distance. When the distance information meets the preset condition, an alarm signal is sent out automatically. Therefore, a user can be prompted to prevent collision with an obstacle; and thus the damage on people by the low structure in a living environment can be substantially reduced.

The invention discloses a no-scanning automobile crashproof laser radar system based on structured light, and a working method thereof. The system comprises a signal processing part, an infrared CCD, a filter, and a laser transmission part. The infrared CCD is provided with the filter, and just receives the wave sent by the laser transmission part. The signal processing part collects the output data of the infrared CCD, carries out the extraction and calculation of imaging of outgoing laser on the surface of the infrared CCD, and obtains a potential target contour in a radar irradiation region and the distance of the potential target contour. The system can detect nearby threat objects in front of a vehicle and in the surroundings of the vehicle, is low in cost, is suitable for large-scale popularization, can more effectively avoid common accidents (rear-end collision, pedestrian attacks and so on), and guarantees the personal and property safety.

An automated vehicle identifier recognition system comprises a collimated infrared (IR) radiation source 7 and a steering mechanism to allow the direction of a beam 5 from the source to be altered and to scan the beam in a predetermined orientation across a target area (e.g. a vehicle registration or license plate). The system also comprises a controller 16 to control the steering and scanning, a receiver to receive IR radiation reflected back from the target area 1 and an image processing system 20 to derive an image of the identifier from the received reflected IR radiation. The IR source could be a laser diode or an IP LED array. The steering mechanism could include mirrors 10,11 or lenses mounted for rotation about orthogonal axes 12,13. An image of the target area can be built up from the data received during a number of scans.
