Abstract

The invention discloses a recognition device of objects in front of an automobile and a recognition method thereof, and relates to driving safety or automatic driving. The recognition device is provided with a searchlight, a camera and a controller, wherein the searchlight is mounted at the front part of the automobile or at the upper part of a windshield, and is used for projecting light composed of red, yellow and green colors to a design region in front of the automobile and generating color lumps; the camera is mounted on the front windshield, and is used for capturing images in front of the automobile and transmitting image data to the controller; and the controller is mounted in the automobile, and is used for analyzing change of the images, controlling an irradiation region of the searchlight, and transmitting an analysis result to a driving safety or automatic driving system in real time. The recognition method comprises the steps that different light sources are formed through control of matching and strength of red, yellow and green colors, and light is projected to the design region in front of the automobile; the camera captures the real-time images in front of the automobile, and sends the images to the controller; and the controller analyzes and compares change of the images formed before and after the searchlight projects the colorful light, and transmits the analysis result to a driving safety device or automatic driving device. According to the recognition device and the recognition method, driving safety can be improved.

Description

A kind of Herba Plantaginis object detector and its recognition methodss
Technical field
The present invention relates to traffic safety or automatic Pilot, more particularly, to a kind of Herba Plantaginis object detector and its identification side Method.
Background technology
Herba Plantaginis object identification is related to the safety of driving.
Chinese patent CN203094033U discloses a kind of based on binocular identifying system vehicle front detection of obstacles auxiliary dress Put, including the LCDs of display lamp, attention device, model LCD12864, MC9S12XS128 single-chip microcomputers, four video cameras, The parts such as power-assisted processor.Photographic head is arranged on two-by-two vehicle front, two photographic head is placed equivalent to binocular, according to away from binocular Visual theory tests the speed range finding, and the data surveyed are calculated according to algorithm, judges whether doubling is dangerous, control brake.Eight Display lamp points out respectively different information, and attention device is by using voice message driver in danger.Install in vehicle front Two photographic head, before whether detection vehicle front has barrier, the image information that photographic head is obtained to show on liquid crystal display screen The position of square barrier and relative velocity now, by the way that rate signal is input into into vehicle-mounted computer brake is controlled.
Chinese patent CN104732245A disclose identification when there is hazardous materials transportation car for coach front with it is pre- Alarm method, the similar round contour feature and distinctive symbol word marking based on hazardous materials transportation vehicle in the front vehicle visual field, builds Found the toy data base of a dangerous materials tank body, data base includes word segment and visuals, the visuals be with The image of similar round feature；Front vehicles shape contour and feature word are fitted with method of least square, if fitting As a result with Data Matching in data base, then judge that front vehicles are hazardous materials transportation vehicle, and then give a warning.
The content of the invention
Present invention aim at providing a kind of Herba Plantaginis object detector.
Another object of the present invention is to provide a kind of Herba Plantaginis object identification method.
The Herba Plantaginis object detector is provided with search lighting apparatuss, image pick-up device and controller；Search lighting apparatuss are arranged on Herba Plantaginis portion or gear Wind glass top, search lighting apparatuss are used for the design section of the light projection of red yellowish green trichromatism composition to front side and produce color lump, take the photograph As device is installed on front windshield, image pick-up device is used to catch the image of front side and view data is transferred to into controller, controls Device is installed on in-car, and controller is used for the change of analysis of the image, the irradiation area of control search lighting apparatuss, and analysis result is passed in real time It is defeated by traffic safety or automated driving system.
The Herba Plantaginis object identification method is comprised the following steps that：
Control red yellowish green trichromatism light with when intensity to constitute different light sources, and project the design area of front side Domain, image pick-up device catches the real time imaging of front side (including road surface) and delivers to controller, the projection of controller com-parison and analysis search lighting apparatuss There is the change of the image before and after color of light, and analysis result is transferred to into traffic safety equipment or autopilot facility.
Beneficial effects of the present invention are：By having color of light to front side projection, controller is helped to analyze Herba Plantaginis in real time Condition of road surface, improves travel safety.
