Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] Such as figure 1 The schematic layout diagram of a perception system of a smart vehicle shown in the present invention includes 1 millimeter wave radar sensor 1, 1 visual sensor 2, several ultrasonic radar sensors 3, and 2 single-line laser radar sensors 4; The scanning range of the laser radar sensor 4 is 180 degrees, and its installation position can be in any horizontal direction on the two corresponding sides of the vehicle, and the vertical installation position should be carried out according to the installation requirements of the laser radar. The installation position of the vision sensor and the millimeter-wave radar needs to be accurately measured. Generally, the vision sensor and the millimeter-wave radar are installed in the center of the front of the car. The purpose is to ensure that the angles on the left and right sides of the center li...

Abstract

The invention relates to an information fusion method of an intelligent vehicle perception system, and specifically relates to an information fusion control method of an intelligent vehicle perceptionsystem. The vehicle perception system includes a millimeter wave radar installed directly in front of the head of a vehicle, a visual sensor mounted directly above the millimeter wave radar, a plurality of ultrasonic radars installed in the forward direction, and single line laser radars installed on the left and right sides of the vehicle. The information fusion control method includes the steps: determining whether the ultrasonic sensors detect an obstacle, if an obstacle is detected, no longer processing the information of the millimeter wave and the visual sensor, and if not, processing the information of the millimeter wave and the visual sensor; and if the millimeter wave and the visual sensor detect the same obstacle, performing fusion processing on the information of the two sensors by a processor, and if only one sensor detects the obstacle, only outputting the information of the corresponding detector. The information fusion control method of an intelligent vehicle perception system has the advantages of being high in the processing speed, saving system resources and being reliable in the beneficial effects, and can be used for realizing development and application of intelligent driving functions such as lane keeping or driverless driving.

Description

technical field [0001] The invention relates to an information fusion method of an intelligent vehicle perception system, belonging to the field of intelligent vehicles. Background technique [0002] Intelligent assisted driving including lane keeping assistance, adaptive cruise, etc., and the upcoming automatic driving or unmanned driving can greatly facilitate people's travel, reduce congestion and accidents, and bring great convenience to human production and life. . In order to achieve intelligent driving, it is necessary to detect the surrounding environment of the vehicle through sensors. Commonly used sensors include vision sensors, ultrasonic sensors, millimeter-wave radar sensors and lidar sensors. Intelligent assisted driving has very high requirements for the sensitivity of environmental sensing and the speed of obstacle judgment, and the requirements for unmanned or automatic driving are even higher. At present, the cost of vehicle environment perception solutio...
