Problems solved by technology

Traditional cars usually only use a single detection model based on a single sensor to obtain obstacle information in the surrounding environment, so it has great limitations in complex climates and complex traffic scenarios, resulting in the inability to accurately identify obstacles. There is a great danger

Embodiment Construction

[0028] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the structures in the drawings are only schematic rather than limiting, so that those skilled in the art can best understand the principles of the present invention, and they are not necessarily drawn to scale.

[0029] FIG. 1 shows a schematic diagram of the method for detecting road obstacles provided by the present invention. As shown in FIG. 1 , three different obstacle detection models are established based on different sensor devices, including a video camera device, a millimeter-wave radar, a laser radar, and an infrared camera device. In a preferred embodiment of the present invention, the video camera device and the infrared camera device can be arranged on the upper end of the front windshield of th...

Abstract

The invention relates to a method and a system for detecting a road barrier. The invention discloses a first barrier detection model based on a video pick-up device, a second barrier detection model based on the video pick-up device and a millimeter-wave radar, and a third barrier detection model based on a three-dimensional laser radar and an infrared pick-up device, wherein complementary detection for the multiple models is formed through a rough set based fuzzy neural network algorithm, so that characteristic information of the road barrier can be obtained in real time. The method and system for detecting the road barrier can carry out real-time and effective road barrier detection under the conditions of different road scenes and different weathers to obtain parameters such as the travelling speed and direction of different barriers exactly, can extract and analyze surrounding environment information of vehicles from the road traffic environment, and can judge abnormal traffic behaviors so as to relieve the current urban traffic pressure and improve traffic management efficiency.

Description

technical field [0001] The invention belongs to the technical field of information detection and processing, and in particular relates to a method and system for detecting and identifying road obstacles based on multi-sensor fusion. Background technique [0002] With the advent of the automobile era, automobile technology, especially automobile safety technology, has received more and more attention. In addition to the electromechanical control that plays a decisive role in vehicle safety in traditional vehicles, real-time access to vehicle information is also an important guarantee for safe driving. Specifically, vehicle information mainly includes vehicle status information and environmental information, among which the perception of environmental information is particularly important. With the development of technology, various sensor devices with different functions can be used to obtain various real-time road condition information. [0003] Currently commonly used veh...
