Description

Technical Field

[0001] The present invention relates to the technical field of vehicle light signals, and in particular to a projection method and system for digital interactive lighting of a vehicle and a computer storage medium. Background Art

[0002] With the development of vehicle technology, especially the electrification and intelligentization of automobiles, digital interactive lighting system technology has emerged. The digital interactive lighting system enables the vehicle to project graphics for displaying itself or for reminding other vehicles or pedestrians.

[0003] A small number of vehicles equipped with digital lighting systems project projections on the road, which are unlikely to intersect, and have limited impact on driving experience and safety. However, as the number of vehicles equipped with digital interactive lighting systems increases, projections will intersect, that is, two or more vehicles will appear on the same road, causing projections to intersect. Intersecting projections will make it difficult for drivers to recognize projection information for manually driven vehicles, and for autonomous vehicles, it will also hinder the recognition of the vehicle's machine vision system. Summary of the invention

[0004] In view of the above-mentioned defects of the prior art, the present invention provides a method for projecting digital interactive lighting in a vehicle, which solves the problem of overlapping projections and poor information recognition caused by too many digital interactive lighting systems in a vehicle, improves the recognition and understanding capabilities of the driver and the system for projection information, and improves the driving experience and safety.

[0007] The detection range is the possible range of other vehicles when the maximum prescribed projection range of the interactive lights of other vehicles overlaps with the maximum prescribed projection range of the controlled vehicle.

[0008] Furthermore, when the acquired road surface image intersects with the image projected by the interactive light of the controlled vehicle, it is determined whether the projection image of the interactive light of the controlled vehicle is used to alert other vehicles; when the projection image of the interactive light of the controlled vehicle is used to alert other vehicles, the projection image of the interactive light of the controlled vehicle is controlled to be within the minimum projection range; otherwise, the projection image of the interactive light of the controlled vehicle is turned off.

[0010] Furthermore, when there are other vehicles whose driving trajectories intersect with the projection range of the interactive lights of the controlled vehicle, it is determined whether the projection image of the interactive lights of the controlled vehicle is used to remind other vehicles. When the projection image of the interactive lights of the controlled vehicle is used to remind other vehicles, the projection image of the interactive lights of the controlled vehicle is controlled to be within the minimum projection range; otherwise, the projection range of the projection image of the interactive lights of the controlled vehicle is not changed.

[0026] Figure 2It is a flowchart of a projection method performed by a projection system for vehicle digital interactive lighting according to the second embodiment. DETAILED DESCRIPTION

[0027] The present invention is further described below in conjunction with examples. It should be understood that these examples are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading this description, various equivalent modifications to this description by those skilled in the art fall within the scope defined by the claims attached to this application.

[0028] The vehicle digital interactive lighting projection system involved in this embodiment includes a vehicle detection module, an image acquisition module, a projection mode discrimination module and a projection control module. The vehicle detection module may include image sensors, millimeter wave radars, laser radars, ranging sensors and other sensing devices and corresponding detection and calculation devices, and these sensing devices transmit information around the controlled vehicle to determine the location and status of other vehicles. The image acquisition module mainly includes an image sensor and a control unit that controls the operation of the image sensor. The projection mode discrimination module is a module for obtaining the controlled vehicle's own information, which can obtain the corresponding information of the vehicle lighting system through the bus form, and can also be integrated into the vehicle lighting system to directly obtain the projection mode information. The projection control module is used to control the lighting system of the controlled vehicle. Similar to the projection mode discrimination module, it can be an independent module that sends information to the vehicle lighting system in the form of a bus, or it can be integrated into the vehicle lighting system for direct control.

[0029] Although the above modules are described separately in this embodiment, it can be understood that this is a logical description distinction, and multiple modules can have some or all of the common components physically to realize their respective functions.

[0030] The method of using the projection system of the vehicle digital interactive light for projection, please combine Figure 1 As shown, the following steps are included:

[0031] When the interactive light of the controlled vehicle is turned on, the vehicle detection module detects whether there are other vehicles within the detection range of the controlled vehicle. The information of the interactive light of the controlled vehicle can be information feedback from the projection control module. The detection range here is the possible range of other vehicles when the maximum prescribed projection range of the interactive light of other vehicles overlaps with the maximum prescribed projection range of the controlled vehicle. The maximum prescribed projection range should be understood as the corresponding range around the vehicle, which is determined according to the corresponding regulations or industry standards. For example, it can be a rectangular area that spreads around the center of the vehicle, or a circular, elliptical area. The possible range is the set of positions where other vehicles can be located when the rectangular area spread around the other vehicles overlaps with the rectangular area spread around the controlled vehicle. In other words, when another vehicle is detected, it is determined whether the maximum prescribed projection range of its interactive light overlaps with the maximum prescribed projection range of the controlled vehicle according to the position of the vehicle, and whether it belongs to other vehicles existing in the detection range of the controlled vehicle. If there is an overlap, it is yes, and if there is no overlap, it is no.

[0032] When there are other vehicles within the detection range of the controlled vehicle, the image acquisition module acquires the road image within the projection range of the interactive light of the controlled vehicle. During this acquisition process, in order to prevent the projection of the interactive light of the controlled vehicle from affecting subsequent recognition, the interactive light of the controlled vehicle is turned off for a short time. The short-term off time can be the time required for the image acquisition module to acquire one frame of image, or the time required to acquire several frames (no more than five frames) of image.

[0033] When the acquired road surface image contains images projected by interactive lights of other vehicles that intersect with the images projected by the interactive lights of the controlled vehicle, the projection control module turns off the projected images of the interactive lights of the controlled vehicle or controls the projected images of the interactive lights of the controlled vehicle to be within the minimum projection range. Since the premise of the method is that the interactive lights of the controlled vehicle are turned on, in order to avoid the interactive lights projected images of the controlled vehicle interfering with the projected images generated by other vehicles (when the interactive lights projected images generated by other vehicles can overlap with the interactive lights projected images of the controlled vehicle, the interactive lights projected images generated by other vehicles have a reminder significance to the controlled vehicle), the interactive lights projected images of the controlled vehicle can be turned off at this time to ensure that the interactive lights projected images of other vehicles are not affected at all.

[0034] As a preferred embodiment, in this embodiment, when the projection control module chooses to turn off the projection image of the interactive light or reduce the range of the projection image of the interactive light, the projection mode discrimination module determines whether the projection image of the interactive light to be projected by the controlled vehicle is used to remind other vehicles or to remind the driver of the controlled vehicle. In order to maintain the interaction between multiple vehicles as much as possible, when the projection image of the interactive light to be projected is used to remind other vehicles, the projection control module selects to control the projection image of the interactive light of the controlled vehicle to be in the minimum projection range, so as to minimize the interference of the projection image of the interactive light of other vehicles and facilitate information recognition while retaining the interactive information generated by the controlled vehicle to the outside, thereby improving safety. When the projection image of the interactive light to be projected is used to remind the driver of the controlled vehicle, the projection control module can choose to turn off the projection image of the interactive light of the controlled vehicle.

[0035] Another embodiment of the vehicle digital interactive light projection system of the present invention further includes a track detection module, which can rely on the sensor device of the vehicle detection module to detect other vehicles around the controlled vehicle. Specifically, when the road image acquired by the image acquisition module does not contain images projected by interactive lights of other vehicles that intersect with the images projected by the interactive lights of the controlled vehicle, it is detected whether there are other vehicles whose driving tracks intersect with the projection range of the interactive lights of the controlled vehicle. The projection method of the vehicle digital interactive light projection system of this embodiment is combined with Figure 2 As shown, the following steps are included:

[0036] When the interactive light of the controlled vehicle is turned on, it is detected whether there are other vehicles within the detection range of the controlled vehicle.

[0037] When there are other vehicles within the detection range of the controlled vehicle, a road surface image within the projection range of the interactive light of the controlled vehicle is acquired.

[0038] When the acquired road image contains images projected by interactive lights of other vehicles that intersect with the image projected by the interactive lights of the controlled vehicle, the projected image of the interactive lights of the controlled vehicle is turned off or the projected image of the interactive lights of the controlled vehicle is controlled to be within the minimum projection range. The specific process of the above steps can be processed in the same way as the previous embodiment, and will not be repeated here.

[0039] Furthermore, when the acquired road image does not contain the interactive light projection images of other vehicles intersecting with the interactive light projection images of the controlled vehicle, it is necessary to further determine whether there are other vehicles whose driving tracks intersect with the projection range of the interactive light of the controlled vehicle. This determination process is performed by the track detection module, and its detection and determination information will be sent to the projection control module to control the interactive light of the controlled vehicle.

[0040] During specific control, the projection mode discrimination module is also combined to determine whether the projection image of the interactive light to be projected by the controlled vehicle is used to remind other vehicles or to remind the driver of the controlled vehicle. That is, when there are other vehicles whose driving tracks intersect with the projection range of the interactive light of the controlled vehicle, the projection mode discrimination module determines whether the projection image of the interactive light of the controlled vehicle is used to remind other vehicles. When the projection image of the interactive light of the controlled vehicle is used to remind other vehicles, the projection control module controls the projection image of the interactive light of the controlled vehicle to be in the minimum projection range, otherwise the projection range of the projection image of the interactive light of the controlled vehicle is not changed.

[0041] The minimum projection range described in the above two embodiments can be limited to the lane where the controlled vehicle is traveling and within a minimum visible distance from the controlled vehicle during specific implementation. In this range, there are no other vehicles during normal driving, so the reminder information can be retained as much as possible to reduce the interference received.

[0042] Finally, it should be pointed out that the specific methods of the above embodiments can form a computer program product. Therefore, the computer program product implemented by the present application can be stored on one or more computer-usable storage media (including but not limited to disk storage, CD-ROM, optical storage, etc.).
