Description

Technical Field

[0001] The present application relates to the field of computer technology, and in particular to a method and device for sending a signal light status, a computer device, and a storage medium. Background Art

[0002] The signal status of traffic lights is an important basis for driving. During the driving process, if the signal status of the traffic lights on the road ahead can be obtained in advance, the driver can plan the route in advance and avoid congested sections, while effectively avoiding problems such as following the car running a red light, driving in the wrong lane, and sudden braking at intersections. On the contrary, if the signal status of the traffic lights on the road ahead cannot be obtained in advance, driving efficiency may be reduced. Therefore, how to obtain the signal status of the traffic lights on the road ahead in advance is a problem that needs to be solved.

[0003] At present, software algorithms are usually used to predict the signal status of traffic lights on the road ahead. However, the signal status obtained by this method has a large error compared with the actual signal status, which may affect driving safety and even increase the probability of accidents.

[0061] Figure 1 Schematic diagram of an implementation environment of a signal light status sending method provided according to an embodiment of the present application. Figure 1 The implementation environment includes a terminal 101 and a server 102. The terminal 101 and the server 102 can be directly or indirectly connected via wired or wireless communication, which is not limited in this application.

[0065] Figure 2 is a flowchart of a signal light status sending method provided according to an embodiment of the present application, the method is applied to a first terminal, see Figure 2, the method comprises the following steps:

[0066] 201. Obtain traffic light information, where the traffic light information includes a state of at least one traffic light and a distance from a first terminal to the at least one traffic light, where the state refers to a color and a reading of the traffic light.

[0067] In an embodiment of the present application, the first terminal obtains traffic light information. The first terminal may be a vehicle-mounted terminal or a mobile terminal. The colors of the traffic lights include red, green and yellow. When the traffic light displays a reading, the reading of the traffic light is recorded as a non-negative integer; when the traffic light does not display a reading, the reading of the traffic light may be recorded as a negative integer. The distance from the first terminal to at least one traffic light may be recorded in "m" to indicate how many meters the distance is, or in "km" to indicate how many kilometers the distance is. For example, the traffic light information obtained by the first terminal is "red, 10, 30m", or the traffic light information is "red, 10, 3km; green, -1, 0.5km".

[0068] 202. Encapsulate the signal light information and the terminal information of the first terminal to obtain broadcast information, wherein the terminal information includes the longitude, latitude and azimuth of the first terminal, the longitude and latitude are used to indicate the position of the first terminal, and the azimuth is used to indicate the moving direction of the first terminal.

[0069] In the embodiment of the present application, the first terminal encapsulates the acquired signal light information and terminal information to obtain broadcast information. The forms of the broadcast information obtained by encapsulating using different encapsulation protocols may not be completely the same, and the embodiment of the present application does not require this. Optionally, the longitude and latitude are expressed in decimal.

[0070] 203. Send a wireless signal carrying broadcast information to a target range by using beamforming, so that a second terminal receiving the wireless signal displays a state of at least one signal light.

[0071] In an embodiment of the present application, the first terminal indiscriminately sends a wireless signal carrying broadcast information to a target range by using beamforming. After receiving the wireless signal, the second terminal within the target range can obtain the status of the traffic light by parsing the broadcast information, thereby sharing the status of the traffic light among the terminals. Among them, the use of beamforming technology can not only realize the directional transmission of wireless signals to the target range, but also improve the transmission quality of wireless signals. Among them, the target range is a sector-shaped range with the coordinates of the first terminal as the center. The terminals within the target range can receive the wireless signal sent by the first terminal and parse the broadcast information in the wireless signal. It should be noted that the second terminal can be a vehicle-mounted terminal or a mobile terminal, and the embodiment of the present application does not limit this.

[0072] An embodiment of the present application provides a method for sending a signal light status, which obtains signal light information through a first terminal and sends a wireless signal carrying the information to a target range, so that a rear terminal that receives the wireless signal can obtain the signal light status in advance, thereby ensuring the accuracy of the obtained signal light status and improving driving efficiency.

[0073] Figure 3 is a flowchart of another method for sending a signal light status according to an embodiment of the present application, the method is applied to a first terminal, see Figure 3 , the method comprises the following steps:

[0074] 301. Acquire a traffic light image, where the traffic light image includes at least one traffic light.

[0075] In an embodiment of the present application, the first terminal obtains a signal light image. The first terminal may be a vehicle-mounted terminal or a mobile terminal. The signal light image refers to an image containing at least one signal light on the road in front of the first terminal. The first terminal obtains the signal light image by directly photographing it with a camera in the first terminal, or by photographing it with a camera in any other terminal and then transmitting the signal light image to the first terminal. In this case, the longitude and latitude coordinates of any of the above terminals and the first terminal are required to be the same, so as to ensure that the first terminal can accurately determine the distance from the first terminal to the signal light based on the acquired signal light image.

[0076] For example, when the first terminal is a vehicle-mounted terminal (such as a vehicle computer), the image of the traffic light can be directly captured by the vehicle-mounted camera; the image of the traffic light can also be captured by the mobile phone camera of other terminals (such as mobile phones) and then transmitted to the first terminal. At this time, the mobile phone should be located in the vehicle. The mobile phone can transmit the image to the first terminal through the server. When the first terminal is a mobile terminal (such as a mobile phone), the first terminal can send a shooting request to the vehicle-mounted terminal (such as a vehicle computer), and the vehicle computer can capture the image of the traffic light through the vehicle-mounted camera. At this time, the mobile phone should be located in the vehicle.

[0077] 302. For any traffic light, determine a distance from the traffic light to the first terminal based on the traffic light image.

[0078] In an embodiment of the present application, the first terminal determines the distance from at least one signal light to the first terminal based on the signal light image. For any signal light, the first terminal can use image recognition technology to determine the distance from the signal light to the first terminal based on the depth of field of the signal light image and the position of the signal light in the signal light image. The distance from the first terminal to at least one signal light can be recorded in "m" to indicate the distance in meters, or in "km" to indicate the distance in kilometers.

[0079] For example, see Figure 4 As shown, Figure 4 This is a schematic diagram of obtaining a signal light status according to an embodiment of the present application. In the figure, there are three signal lights, "Signal Light 1", "Signal Light 2" and "Signal Light 3", in front of the first terminal. The first terminal obtains a signal light image containing the above three signal lights, and uses image recognition technology to identify the distances of the above three signal lights to the first terminal respectively.

[0080] It should be noted that the first terminal can also determine the distance from the signal light to the first terminal by obtaining the latitude and longitude coordinates of the signal light and the first terminal; the distance from the signal light to the first terminal can also be determined by technical means such as infrared ranging, and the embodiments of the present application do not limit this.

[0081] 303. In response to the distance being not greater than the distance threshold, determine a state of the traffic light based on the traffic light image.

[0082] In the embodiment of the present application, the reference value of the state of a traffic light that is too far away from the first terminal is relatively small compared to a traffic light that is shorter away from the first terminal. Therefore, in order to ensure the reliability of the traffic light state determined based on the traffic light image, a distance threshold is set to determine whether to determine the state of the traffic light.

[0083] When the distance from any signal light to the first terminal is less than the distance threshold, the first terminal uses image recognition technology to determine the state of the signal light based on the signal light image. The state of the signal light includes the color of the signal light and the reading of the signal light. The colors of the signal light include red, green and yellow. When the signal light displays the reading, the reading of the signal light is recorded as a non-negative integer; when the signal light does not display the reading, the reading of the signal light can be recorded as a negative integer.

[0084] For example, the first terminal determines that the traffic light state is "red, 10", indicating that the traffic light is red at this time and the countdown is 10s; or determines that the traffic light state is "green, -1", indicating that the traffic light is green at this time and no countdown is displayed.

[0085] In some embodiments, the distance from the signal light to the first terminal may be greater than a distance threshold. Accordingly, in response to the distance being greater than the distance threshold, the first terminal ignores the signal light.

[0086] When the signal light is too far away from the first terminal, the reference value to the first terminal is small, so there is no need to determine the state of the signal light and the signal light is ignored.

[0087] In some embodiments, the terminal may also only obtain the status of the signal light with the shortest distance to the first terminal. Accordingly, the first terminal obtains a signal light image, the signal light image includes at least one signal light; based on the signal light image, a target signal light is determined, the target signal light is the signal light with the shortest distance to the first terminal; based on the signal light image, the status of the target signal light is determined.

[0088] In order to simplify the processing, the first terminal may use image recognition technology to directly determine the target signal light with the shortest distance to the first terminal based on the depth of field of the image and the position of the signal light in the image.

[0089] 304. Encapsulate the signal light information and the terminal information of the first terminal to obtain broadcast information, wherein the terminal information includes the longitude, latitude and azimuth of the first terminal, the longitude and latitude are used to indicate the position of the first terminal, and the azimuth is used to indicate the moving direction of the first terminal.

[0090] In the embodiment of the present application, the forms of the broadcast information obtained by encapsulating using different encapsulation protocols may not be exactly the same, and the embodiment of the present application does not require this. Optionally, the direction of travel of the first terminal may be represented by an azimuth, or the north direction may be used as a reference, the north-east direction may be recorded as a positive degree, and the north-west direction may be set as a negative degree. It should be noted that the embodiment of the present application does not limit this.

[0091] In some embodiments, the terminal information of the first terminal is obtained from other devices. Accordingly, the longitude and latitude of the first terminal are obtained from a positioning device, and the positioning device is used to determine the location of the terminal; the azimuth of the first terminal is obtained from a compass device, and the compass device is used to determine the direction of travel of the terminal. Among them, the positioning device and the compass device can be devices in the first terminal or external devices connected to the first terminal. The positioning device refers to a device that locates the location of the chip based on the communication between the satellite and the chip. In the embodiment of the present application, the chip should be located on the first terminal.

[0092] 305. Send a wireless signal carrying broadcast information to a target range by using beamforming, so that a second terminal receiving the wireless signal displays a state of at least one signal light.

[0093] In the embodiment of the present application, the first terminal indiscriminately sends a wireless signal carrying broadcast information to the target range by beamforming. After receiving the wireless signal, the second terminal in the target range can obtain the signal light status, thereby realizing the sharing of the signal light status among the terminals.

[0094] Among them, the use of beamforming technology can not only realize the directional transmission of wireless signals to the target range, but also improve the transmission quality of wireless signals. Terminals located in the target range have the authority to receive and parse the wireless signals sent by the first terminal, and terminals located outside the target range cannot receive the wireless signals sent by the first terminal. In order to effectively reduce interference to adjacent terminals and relative terminals, the first terminal usually sends wireless signals in the direction opposite to the direction of travel. It should be noted that the second terminal can be a vehicle-mounted terminal or a mobile terminal, and the embodiments of the present application are not limited to this.

[0095] In some embodiments, based on the direction of travel of the first terminal, the first terminal determines the target range. Accordingly, based on the direction of travel of the first terminal, the first terminal determines the signal transmission direction, which is opposite to the direction of travel; based on the signal transmission direction and the signal transmission angle, the first terminal determines the target range, which is a fan-shaped range, the signal transmission direction is the center direction of the fan-shaped range, and the signal transmission angle is the angle of the fan-shaped range.

[0096] See for example Figure 5 As shown, Figure 5 It is a schematic diagram of a signal light status transmission provided according to an embodiment of the present application. In the figure, the first terminal sends a wireless signal to a target range behind, and the target range is a fan-shaped range between two dotted lines in the figure. The second terminal located in the target range can receive the wireless signal sent by the first terminal, and the nth terminal located outside the target range cannot receive the wireless signal sent by the first terminal.

[0097] To make the process of signal light status transmission clearer, see Figure 6 As shown, Figure 6 It is a flowchart of sending a signal light status according to an embodiment of the present application. The first terminal executes step 601 to obtain the signal light status and the distance from the signal light to the first terminal. The first terminal executes step 602 to determine whether the distance from the signal light to the first terminal exceeds the distance threshold. If the distance exceeds the distance threshold, the first terminal executes step 604 to ignore the signal light. After a certain time interval, the first terminal re-executes step 601. If the distance does not exceed the distance threshold, the first terminal executes step 603 to obtain the terminal information of the first terminal; then executes step 605 to encapsulate the information; and then executes step 606 to send a wireless signal. After a certain time interval, the first terminal re-executes step 601.

[0098] 306. In response to receiving the wireless signal from the third terminal, parse the broadcast information carried by the wireless signal to obtain the signal light information of the third terminal and the terminal information of the third terminal.

[0099] In an embodiment of the present application, after receiving a wireless signal sent by a third terminal, the first terminal parses the broadcast information carried by the wireless signal. The first terminal is within the target range of the third terminal for sending wireless signals. The third terminal can be a vehicle-mounted terminal or a mobile terminal, which is not limited in the embodiment of the present application.

[0100] It should be noted that in some possible situations, after the first terminal receives the wireless signal sent by the third terminal, it is unable to parse the broadcast information carried by the wireless signal. In this case, the first terminal ignores the wireless signal and waits to receive a new signal again.

[0101] 307. Determine an angle between a moving direction of the third terminal and a moving direction of the first terminal based on the terminal information of the third terminal and the terminal information of the first terminal.

[0102] In the embodiment of the present application, based on the azimuth of the third terminal and the azimuth of the first terminal, the first terminal determines the angle between the travel direction of the third terminal and the travel direction of the first terminal. For example, if the azimuth of the third terminal is 1° and the azimuth of the first terminal is 359°, then it can be determined that the angle between the travel directions of the two is 2°.

[0103] 308. In response to the included angle being within the included angle range, determine a terminal distance between the first terminal and the third terminal.

[0104] In the embodiment of the present application, when the angle is within the angle range, the first terminal determines the terminal distance to the third terminal based on the latitude and longitude of the third terminal and the latitude and longitude of the first terminal. The terminal distance can be recorded in "m" units, indicating how many meters the distance is, or in "km" units, indicating how many kilometers the distance is.

[0105] 309. In response to the terminal distance being within the distance threshold range, display the state of the signal light based on the signal light information of the third terminal.

[0106] In the embodiment of the present application, the status of the signal light may be displayed in the display device of the first terminal, or the first terminal may send the information to other terminals and display it in the other terminals. The embodiment of the present application does not limit this.

[0107] The distance threshold range is used to indicate the distance range within which the first terminal can receive the wireless signal. It should be noted that the maximum value of the distance threshold range should not be set too large, otherwise the range within which the first terminal can receive the wireless signal will be too large, and the first terminal will receive the wireless signal of the signal light status with a small reference value, thereby causing unnecessary interference.

[0108] Optionally, the setting of the distance threshold range can be adjusted according to the moving speed and surrounding environment of the first terminal. For example, when the road conditions around the first terminal are good and it can move normally and quickly, the demand for the traffic light information ahead is small, and the distance threshold can be lowered to only receive wireless signals carrying traffic light status with greater reference value; when there is a traffic jam around the first terminal, in order to provide more sufficient traffic light information, the distance threshold can be increased, so that the first terminal can re-plan the route based on more sufficient traffic light information.

[0109] In some embodiments, the angle or the terminal distance may not be within the range. Accordingly, the first terminal ignores the wireless signal in response to the angle not being within the angle range, or the terminal distance not being within the distance threshold range. Among them, when the angle exceeds the angle range, it means that the first terminal and the third terminal are traveling in different directions. At this time, the traffic light information carried in the wireless signal sent by the third terminal has little reference value to the first terminal, so the wireless signal is ignored. For example, the first terminal is traveling straight north on Road 1. At this time, the azimuth of the first terminal is 0°. The third terminal turns right on Road 1 and is about to enter Road 2. At this time, the azimuth of the third terminal is 45°. It can be determined that the angle between the two directions of travel is 45°. At this time, the wireless signal sent by the third terminal carries the traffic light information on Road 2, which has little reference value to the first terminal, so the wireless signal is ignored and waits for receiving a new signal again.

[0110] It should be noted that when the angle is not within the angle range, or the terminal distance is not within the distance threshold range, the first terminal may also display the state of the signal light based on the signal light information of the third terminal. Although the signal light information carried in the wireless signal sent by the third terminal at this time has little reference value to the first terminal, it can enable the first terminal to understand the surrounding road conditions. Therefore, the embodiments of the present application do not limit this.

[0111] To make the process of receiving the signal light status clearer, see Figure 7 As shown, Figure 7It is a flowchart of a signal light status reception provided according to an embodiment of the present application. In response to receiving a wireless signal from a third terminal, the first terminal executes step 701, parses the broadcast information, and obtains the signal light information of the third terminal and the terminal information of the third terminal.
