Description

Technical Field

[0001] The present invention relates to the technical field of sending traffic police hand gesture signals, and in particular to a method, device, equipment and medium for sending traffic police hand gesture signals. Background Art

[0002] With the development of autonomous driving technology, autonomous driving vehicles and ordinary vehicles enter a mixed traffic state. In this mixed traffic state, autonomous driving vehicles and ordinary vehicles travel together, and special situations that require traffic police command will inevitably occur; autonomous driving vehicles need to follow the traffic police's command in special situations, but relying solely on the sensor equipment and algorithms of autonomous driving vehicles to recognize traffic police gestures has always been a difficult problem, with high costs and complex algorithms. Moreover, the advantages of single-vehicle recognition of traffic police are limited to multiple limiting factors such as line of sight and blind spots. Traffic police cannot directly command and issue instructions to intelligent networked vehicles, and can only rely on vehicles to automatically recognize their gestures, and the accuracy is highly dependent on vehicle-side sensor equipment and computing power algorithms, which is not direct and efficient enough.

[0003] Existing technologies mainly focus on actively identifying traffic police gestures through vehicles, generally through signal collection through sensors, or judgment through algorithms such as video image recognition. Some studies also collect traffic police gestures through acceleration sensors, use gesture recognition systems to identify traffic police enforcement actions, and display them on vehicle-mounted or wearable displays. Some studies collect signals based on traffic police gestures, but due to the lack of a dedicated human-vehicle-road communication network, traffic police can only send gesture signals to large screens or other road-side devices, and cannot send signals directly to unmanned or intelligent networked vehicles in a timely and fast manner.

[0004] The above technologies are mainly focused on the "recognition" of traffic police gestures, which generally require the use of complex sensing equipment, computing equipment and complex algorithms. The above methods and technologies are not applicable in the field of Internet of Vehicles. Due to the large number of manufacturers of connected vehicles, the standards have not yet been fully unified, and the intelligence levels of connected vehicles are different. For vehicles with low intelligence levels, the above methods are not applicable. In the field of Internet of Vehicles, aftermarket vehicles with low intelligence technology cannot automatically recognize the gestures of traffic police. Therefore, there is a general lack of a direct and effective communication channel for traffic police to issue traffic command information to unmanned vehicles and intelligent connected vehicles. Summary of the invention

[0005] The purpose of the present invention is to propose a method, device, equipment and medium for sending traffic police gesture signals, so as to solve the technical problem of how to send traffic police gesture signals to networked vehicles with the help of the communication network of the Internet of Vehicles and equipment such as road-side RSU.

[0030] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention.

[0032] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] like Figure 1 FIG. 1 is a schematic diagram of an embodiment of a method for sending a traffic police hand gesture signal provided by the present invention. In this embodiment, the method comprises the following steps:

[0034] Step S1, in response to the signal issuing instruction of the traffic conductor, the corresponding traffic police gesture type is determined; wherein, the signal issuing instruction includes a plurality of instruction items corresponding to the traffic police gesture types, each instruction item corresponds to a type item in the traffic police gesture type; it is understandable that there are only a few types of existing traffic police gestures, namely: stop signal, straight signal, left turn signal, left turn waiting signal, right turn signal, lane change signal, slow down signal, signal to indicate the vehicle to pull over, by redefining several fixed signals corresponding to traffic police gestures in the device or vehicle network communication system. A gesture signal transmitter including a V2X vehicle network communication module can be installed on the traffic command device or wearable device of the traffic police, preferably the wearable device; the traffic police gesture signal buttons preset in advance by the signal transmitter mainly include a plurality of buttons containing the above multiple messages; when the traffic police encounter an intelligent networked vehicle or an autonomous driving vehicle that needs to be directed during traffic law enforcement, specific instructions can be quickly sent directly to the vehicle through the button.

[0035] In a specific embodiment, the traffic police gesture types include at least a stop signal, a straight signal, a left turn signal, a left turn waiting signal, a right turn signal, a lane change signal, a slow down signal, and a signal to indicate that the vehicle should pull over.

[0036] Step S2, according to the traffic police gesture type, the corresponding traffic police gesture signal is identified from the preset traffic police gesture signal library, and the identified traffic police gesture signal is sent to the networked vehicle corresponding to the location of the traffic commander. It can be understood that based on the communication protocol of the Internet of Vehicles, 8 fixed-format messages are redefined in the Internet of Vehicles system, corresponding to multiple gestures of the traffic police, and a signal generator with multiple gesture buttons preset is placed on a handheld terminal or wearable of the traffic police, and the sending priority of the signal is set to the highest in the Internet of Vehicles system, higher than other signal devices such as traffic lights and signs. When the traffic police need to send a gesture command to the networked vehicle, they can directly click the response button to send it.

[0037] In a specific embodiment, a plurality of traffic police gesture signals encapsulated into a plurality of formats are provided in the traffic police gesture signal library, and each traffic police gesture signal corresponds to a type item in the traffic police gesture type. Specifically, after the corresponding traffic police gesture type is determined, the traffic police gesture signal corresponding to the traffic police gesture type is identified from the traffic police gesture signal library; the traffic police gesture signal of the corresponding format is retrieved from the encapsulated traffic police gesture signals of a plurality of formats according to the signal format receivable by the networked vehicle, and the retrieved traffic police gesture signal is sent to the networked vehicle. That is, a plurality of new gesture signals are defined in the Internet of Vehicles system and encapsulated into a plurality of fixed-format messages, including but not limited to: stop signal, straight signal, left turn signal, left turn waiting signal, right turn signal, lane change signal, slow down signal, and signal for the vehicle to pull over. The priority of the gesture signal sent by the traffic police in the system is set to be higher than the priority of the signal sent by the traffic light and the sign.

[0038] In one embodiment, when the networked vehicle receives a traffic police gesture signal, if the traffic police gesture signal conflicts with a traffic light signal or signboard signal that it recognizes, the networked vehicle performs a corresponding driving action according to the received traffic police gesture signal.

[0041] According to the traffic police gesture type, the corresponding traffic police gesture signal is identified from the preset traffic police gesture signal library, and the identified traffic police gesture signal is sent to the connected vehicle corresponding to the location of the traffic commander.

[0042] Specifically, the traffic police gesture types include at least a stop signal, a straight-ahead signal, a left turn signal, a left turn waiting signal, a right turn signal, a lane change signal, a slow-down signal, and a signal to pull over.
