AI Technical Summary

Benefits of technology

The invention provides a system and method for generating an image of the surroundings of an articulated vehicle by combining images from cameras on the first and second vehicles. The relative position between the two vehicles can be determined based on an angle between them or the motion of the vehicles. The system can also include an active sensing system to provide additional information about the environment. The combined image is a birds-eye view of the surroundings of the articulated vehicle. The technical effects of the invention include improved visibility and safety for the driver and reduced risk of accidents.

Problems solved by technology

Existing algorithms for the related art systems cannot combine the images if the cameras change their relative positions, such as if one camera is mounted on the tractor and another camera is mounted on the trailer, and the tractor and trailer are traveling in different directions.

Embodiment Construction

[0022]FIG. 1 shows a block diagram of an exemplary embodiment of a system for generating an image of the surroundings of an articulated vehicle, which includes at least two vehicles that may move with respect to each other. As shown in FIG. 1, the system includes a memory 10 and a processor 20 coupled to the memory 10. The processor 20 includes logic 30-50, which will be described in more detail below in connection with FIG. 2. The processor 20 can be any type of processor, such as a microprocessor, a field programmable gate array (FPGA), and / or an application specific integrated circuit (ASIC). When the processor 20 is a microprocessor, logic 30-50 can be processor-executable code that is loaded from the memory 10.

[0023]FIG. 2 shows a flowchart of an exemplary embodiment of a method for generating an image of the surroundings of the articulated vehicle. For example, as shown in FIG. 3, the articulated vehicle may include a first vehicle 200 that is a tractor and a second vehicle 21...

Abstract

Systems and methods for generating an image of the surroundings of an articulated vehicle are provided. According to an aspect of the invention, a processor determines a relative position between a first vehicle of an articulated vehicle and a second vehicle of the articulated vehicle; receives a first image from a first camera arranged on the first vehicle and a second image from a second camera arranged on the second vehicle; and combines the first image and the second image based on the relative position between the first vehicle and the second vehicle to generate a combined image of surroundings of the articulated vehicle.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to systems and methods for generating an image of the surroundings of an articulated vehicle, in which different parts of the vehicle are capable of moving with respect to each other. An example of an articulated vehicle is a tractor-trailer in which a tractor pulls a trailer. The tractor and the trailer may travel in different directions at times, such as when the tractor begins to turn a corner.[0002]Related art systems use multiple cameras arranged on a single-body vehicle to generate a birds-eye view image of the surroundings of the vehicle. For example, U.S. Pat. No. 7,139,412 discloses a system in which a plurality of cameras are mounted on a vehicle such that there is some overlap between the fields of view of adjacent cameras. Separate images acquired by the plurality of cameras are combined to generate a birds-eye view image of the surroundings of the vehicle.[0003]In these related art systems, the locations of ...
