Automatic driving method and system based on infrared polarization image sensor

Abstract

The invention discloses an automatic driving method and system based on an infrared polarization image sensor. The method comprises steps that a sensor system of an infrared polarization image sensor obtains a three-dimensional infrared polarization image containing polarization information of the surrounding environment of a vehicle, a machine learning unit in a host system determines the type of an infrared polarization image target object, distance measurement is conducted on the target object based on a visual algorithm, and the motion state of the target object is predicted; and the motion control signal is sent to a motion control system to adjust the motion state of the vehicle and realize an automatic driving function. The contrast of the target and the background in the infrared polarization image is high, the detail features of the target are prominent, and the target recognition effect is obvious.

Description

technical field [0001] The present application relates to the field of automatic driving, in particular to an automatic driving method and system based on an infrared polarization image sensor. Background technique [0002] Ranging is the core function of vehicle automatic driving technology. The most common technical method is to achieve ranging through laser radar (LIDAR). With the commercialization of vehicles with automatic driving functions, a large number of vehicles on the road use the same radar scanning. There is a phenomenon of mutual interference. The radar is easy to confuse the pulse sent by the nearby vehicle and the signal echo sent by itself, which will cause the radar to fail and even pose a threat to the safety of the vehicle and personnel. In addition, the detection range of automotive lidar is limited, and it is difficult to measure the distance of objects beyond 150 meters. The short detection distance will also limit the speed of the vehicle, which is n...

[0002] Ranging is the core function of vehicle automatic driving technology. The most common technical method is to achieve ranging through laser radar (LIDAR). With the commercialization of vehicles with automatic driving functions, a large number of vehicles on the road use the same radar scanning. There is a phenomenon of mutual interference. The radar is easy to confuse the pulse sent by the nearby vehicle and the signal echo sent by itself, which will cause the radar to fail and even pose a threat to the safety of the vehicle and personnel.

In addition, the detection range of automotive lidar is limited, and it is difficult to measure the distance of objects beyond 150 meters. The short detection range will also limit the speed of the vehicle, which is not conducive to high-speed driving

In addition, it is difficult for lidar to work around the clock, and it is difficult to work normally in special environments such as strong light, rain or fog
