It should be noted that in other embodiments, the vehicle detection module 12 further includes an electronic device configured in the vehicle in an Advanced Driver Assistance Systems (ADAS) manner, so that the vehicle and the vehicle condition display device 100 can communicate or position with each other by the ADAS technology, and cooperate with the image capturing device to obtain more accurate vehicle information.
The image capturing device is, for example, a camera using a Charge Coupled Device (CCD) lens or a Complementary Metal Oxide Semiconductor (CMOS) lens, which can be used for capturing images or videos of a scene.
The light-emitting indication module 14 includes a plurality of light-emitting indication units, and the light-emitting indication units respectively indicate different colors, for example, light-emitting diodes (L ED), and can be used to display colors such as red, orange, or green.
The following description will be given taking the vehicle condition display apparatus 100 as an example of the configuration in the street lamp. In detail, referring to fig. 1B, when the vehicle condition display apparatus 100 is a part of a street lamp, the light-emitting indication module 14 may be disposed on a lamp post of the street lamp, for example, and may display different light-emitting states according to the control signal, and the following detailed description is provided for an embodiment in which the light-emitting indication module 14 displays different light-emitting states. In addition, in fig. 1B, the image capturing devices 12_1 to 12_2 of the vehicle detecting module 12 are, for example, disposed on a street lamp and used for capturing road and vehicle operation conditions, and taking this embodiment as an example, capture vehicles passing through the street lamp on the road to obtain vehicle information, where the vehicle information may be an image or a movie of the vehicle, which is not limited herein. After capturing the vehicle information, the server (i.e., the server in the vehicle detection module 12, not shown in the figure) connected to the vehicle condition display apparatus 100 may receive the vehicle information and analyze the vehicle information to generate a determination result, wherein the determination result may include vehicle identification, road (e.g., an expressway or a road with a curb parking space), vehicle operation condition (e.g., whether the vehicle is stopped (e.g., jammed or stopped at the curb) or driving status), vehicle front-back sequence, and distance between the vehicle and other vehicles around the front-back, without limitation. Then, the control module 10 of the vehicle condition display apparatus 100 can generate a corresponding control signal according to the aforementioned determination result to control the light-emitting indication module 14 to display a corresponding light-emitting state.
The present invention can also configure the aforementioned plurality of vehicle condition display apparatuses 100 to constitute one vehicle condition display system. For example, fig. 2 is a schematic diagram of a vehicle condition display system according to an embodiment of the invention.
Referring to fig. 2, taking an example that the vehicle condition display system 1000, for example, the plurality of vehicle condition display devices 100 are respectively disposed on a plurality of street lamps, the vehicle condition display system 1000 may include vehicle condition display devices 100_1 to 100_ 3. The vehicle condition display apparatuses 100_1 to 100_3 may be respectively the same as the vehicle condition display apparatus 100 described above. In this example, the vehicle condition display devices 100_1 to 100_3 may further have communication units 51 to 53, respectively, so that the vehicle condition display devices 100_1 to 100_3 can perform wired or wireless signal/data transmission therebetween. In addition, in the present embodiment, the street lamps provided with the vehicle condition display apparatuses 100_1 to 100_3 may be disposed at equal intervals from each other.
The communication units 51 to 53 may be components supporting signal transmission of global system for mobile communication (GSM), Personal Handyphone System (PHS), Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, long term evolution (L TE) system, Worldwide Interoperability for Microwave Access (WiMAX) system, wireless fidelity (Wi-Fi) system, or bluetooth.
In this example, the vehicle condition display devices 100_1 to 100_3 may respectively have two image capturing devices. For example, the vehicle condition display device 100_1 may include the image capturing device 12_3 and another image capturing device (not shown). The vehicle condition display device 100_2 may include image capturing devices 12_4 to 12_ 5. The vehicle condition display device 100_3 may include an image capturing device 12_6 and another image capturing device (not shown). In addition, the ranges that can be captured by the image capturing devices of two adjacent vehicle condition display devices partially overlap with each other. Taking the adjacent vehicle condition display devices 100_1 to 100_2 as examples, the range that can be captured by the image capturing device 12_3 of the vehicle condition display device 100_1 and the range that can be captured by the image capturing device 12_4 of the vehicle condition display device 100_2 overlap in the area 400. Taking the neighboring vehicle condition display devices 100_2 to 100_3 as examples, the range that can be captured by the image capturing device 12_5 of the vehicle condition display device 100_2 and the range that can be captured by the image capturing device 12_6 of the vehicle condition display device 100_3 overlap the area 402.
In this example, the server (not shown) may determine whether the target vehicle is located in front of or behind a plurality of preset distances or whether the target vehicle is close to the target vehicle within the preset distances according to the images captured by the vehicle condition display devices 100_1 to 100_3, respectively, so as to generate a determination result. Then, the vehicle condition display devices 100_1 to 100_3 can transmit the determination result through the communication units 51 to 53, for example, and the control modules of the vehicle condition display devices 100_1 to 100_3 can generate the control signals according to the determination result to respectively control the light-emitting indication modules of the vehicle condition display devices 100_1 to 100_3 to display the corresponding light-emitting states according to the control signals. In this example, the vehicle condition display devices 100_1 to 100_3 can transmit the images captured respectively back to the server at any time. The server determines whether a target vehicle is present at the front and rear of the target vehicle within a plurality of preset distances or whether the target vehicle is close to the target vehicle within the preset distances, for example, every 500ms, and then generates a determination result. In addition, the time for the control modules of the vehicle condition display devices 100_1 to 100_3 to generate the control signal according to the determination result is, for example, less than 100 ms.
The following describes a vehicle condition display method applied to the vehicle condition display apparatus (or vehicle condition display system) of the present invention in a more detailed embodiment.
In more detail, fig. 3 is a flowchart of a vehicle condition displaying method according to an embodiment of the invention.
Referring to fig. 1A, fig. 2 and fig. 3, the example of the vehicle condition display system 1000 having the vehicle condition display devices 100_1 to 100_3 is continued, and the vehicle condition display devices 100_1 to 100_3 have the light-emitting indication modules 14_1 to 14_3, respectively. The light emitting indication modules 14_1 to 14_3 are similar to the light emitting indication module 14.
First, the vehicle condition display devices 100_1 to 100_3 may capture images of vehicles traveling on a road through at least one image capture device of the vehicle condition display devices 100_1 to 100_3 to obtain vehicle information of one or more vehicles (step S201). Wherein the one or more vehicles include a target vehicle. Then, the server connected to the vehicle condition display devices 100_1 to 100_3 analyzes the vehicle information and generates a determination result. The control module of each of the vehicle condition display devices 100_1 to 100_3 respectively controls the light-emitting indication modules 14_1 to 14_3 to display the corresponding light-emitting state according to the determination result (step S203).
In particular, the more detailed execution of step S203 can be implemented as the first and second embodiments described below.
[ first embodiment ]
Fig. 4 is a flowchart of a vehicle condition displaying method according to a first embodiment of the invention. Fig. 5 is a schematic diagram of a vehicle condition display device according to an embodiment of the invention showing different light emitting states.
Referring to fig. 4 and 5, it is assumed that in the initial state, when no vehicle is running on the lane, the vehicle condition display devices 100_1 to 100_3 are set to continuously display the third color (e.g., green). Once the vehicle passes through one of the vehicle condition display apparatuses 100_1 to 100_3, the vehicle detection module of one of the vehicle condition display apparatuses 100_1 to 100_3 may analyze the vehicle information (e.g., captured images of the road and the vehicle operation condition) (step S301) and perform the subsequent steps, for example, the vehicle detection module of one of the vehicle condition display apparatuses 100_1 to 100_3 may determine the sequence of the vehicle according to the vehicle information. In the embodiment of fig. 5, the vehicle detection modules (e.g., the servers at the rear end) of the vehicle condition display apparatuses 100_1 to 100_3 can determine whether there are other vehicles within a first distance (e.g., fifty meters) in front of the target vehicle (e.g., the vehicle C1) according to the vehicle information (step S303). When it is determined that there is another vehicle (e.g., the vehicle C3) within fifty meters of the front of the vehicle C1, the control module of at least one of the vehicle condition display devices 100_1 to 100_3 controls the light-emitting indication module of the vehicle condition display device to which the control module belongs to continuously display the first color (e.g., red) (step S305). In this example, the control module of the vehicle condition display device 100_2 controls the light-emitting indication module 14_2 to continuously display red to make the driver of the vehicle C1 know that there is a vehicle in the fifty meters ahead of the vehicle C1.
Then, the vehicle detection modules of the vehicle condition display apparatuses 100_1 to 100_3 may also determine whether there are other vehicles within a first distance (e.g., within fifty meters) behind the vehicle C1 according to the vehicle information (step S307). When it is determined that there is another vehicle (e.g., the vehicle C2) in fifty meters behind the vehicle C1, the control module of at least one of the vehicle condition display devices 100_1 to 100_3 controls the light-emitting indication module of the vehicle condition display device to which the control module belongs to periodically flash to display the first color (e.g., flash red at an interval of 3 seconds) (step S309). In this example, the control module of the vehicle condition display device 100_2 controls the light-emitting indication module 14_2 to periodically flash red to make the driver of the vehicle C1 know that there is a vehicle behind the vehicle C1 at fifty meters.
When it is determined in step S307 that there is no other vehicle behind the vehicle C1 at fifty meters, the vehicle detection module of one of the vehicle condition display devices 100_1 to 100_3 may determine whether there is another vehicle behind the vehicle C1 at a second distance (e.g., one hundred meters) according to the vehicle information (step S311). When it is determined that there is another vehicle (e.g., the vehicle C2) within one hundred meters behind the vehicle C1, the control module of at least one of the vehicle condition display devices 100_1 to 100_3 controls the light-emitting indication module of the vehicle condition display device to which the control module belongs to periodically flash to display the second color (e.g., flash orange at an interval of 3 seconds) (step S313). In this example, the control module of the vehicle condition display apparatus 100_2 controls the light-emitting indication module 14_2 to periodically and flashing to display orange color to make the driver of the vehicle C1 know that there is a vehicle in fifty to one hundred meters behind the vehicle C1.
When it is determined in step S311 that there is no other vehicle behind the vehicle C1 within one hundred meters, the control module of at least one of the vehicle condition display devices 100_1 to 100_3 controls the light-emitting indication module of the vehicle condition display device to which the control module belongs to continuously display red (step S315). In this example, the control module of the vehicle condition display device 100_2 controls the light-emitting indication module 14_2 to continuously display red to make the driver of the vehicle C1 know that there is a vehicle in the fifty meters ahead of the vehicle C1. And returning to the step S301, and repeating the steps S303 to S347.
In addition, when it is determined in step S303 that there is no other vehicle in the fifty meters in front of the vehicle C1, the vehicle detection modules of the vehicle condition display apparatuses 100_1 to 100_3 may determine whether there is another vehicle in the second distance (e.g., one hundred meters) in front of the vehicle C1 according to the vehicle information (step S319). When it is determined that there is another vehicle (e.g., the vehicle C3) within one hundred meters of the front of the vehicle C1, the control module of at least one of the vehicle condition display devices 100_1 to 100_3 controls the light-emitting indication module of the vehicle condition display device to which the control module belongs to continuously display a second color (e.g., orange) (step S321). In this example, the control module of the vehicle condition display device 100_2 controls the light-emitting indication module 14_2 to continuously display the orange color to make the driver of the vehicle C1 know that there is a vehicle in front of the vehicle C1 by one hundred meters. Specifically, the server may determine whether the target vehicle is present at the front and rear of the target vehicle within a plurality of preset distances or whether the target vehicle is close to the target vehicle within the preset distances, for example, every 500ms, and then generate a determination result. In addition, the time for the control modules of the vehicle condition display devices 100_1 to 100_3 to generate the control signal according to the determination result is, for example, less than 100 ms.
Then, the vehicle detection modules of the vehicle condition display apparatuses 100_1 to 100_3 may also determine whether there are other vehicles within a first distance (i.e., within fifty meters) of the rear of the vehicle C1 according to the vehicle information (step S323). When it is determined that there is another vehicle (e.g., the vehicle C2) in fifty meters behind the vehicle C1, the control module of at least one of the vehicle condition display devices 100_1 to 100_3 controls the light-emitting indication module of the vehicle condition display device to which the control module belongs to periodically flash to display the first color (e.g., flash red at an interval of 3 seconds) (step S325). In this example, the control module of the vehicle condition display device 100_2 controls the light-emitting indication module 14_2 to periodically flash red to make the driver of the vehicle C1 know that there is a vehicle behind the vehicle C1 at fifty meters.
When it is determined in step S323 that there is no other vehicle behind the vehicle C1 within fifty meters, the vehicle detection module of one of the vehicle condition display devices 100_1 to 100_3 may determine whether there is another vehicle behind the vehicle C1 within a second distance (i.e., within one hundred meters behind) according to the vehicle information (step S327). When it is determined that there is another vehicle (for example, the vehicle C2) within one hundred meters behind the vehicle C1, the control module of at least one of the vehicle condition display devices 100_1 to 100_3 controls the light-emitting indication module of the vehicle condition display device to which the control module belongs to periodically flash to display the second color (for example, flash orange at an interval of 3 seconds) (step S329). In this example, the control module of the vehicle condition display apparatus 100_2 controls the light-emitting indication module 14_2 to periodically and flashing to display orange color to make the driver of the vehicle C1 know that there is a vehicle in fifty to one hundred meters behind the vehicle C1.
When it is determined in step S327 that there is no other vehicle behind the vehicle C1 within one hundred meters, the control module of at least one of the vehicle condition display devices 100_1 to 100_3 controls the light-emitting indication module of the vehicle condition display device to which the control module belongs to continuously display the second color (e.g., orange) (step S331). In this example, the control module of the vehicle condition display apparatus 100_2 controls the light-emitting indication module 14_2 to continuously display the orange color to make the driver of the vehicle C1 know that there is a vehicle in front of the vehicle C1 at fifty to one hundred meters.
In addition, when it is determined in step S319 that there is no other vehicle within one hundred meters in front of the vehicle C1, the vehicle detection modules of the vehicle condition display apparatuses 100_1 to 100_3 can determine whether there is another vehicle within a third distance (e.g., one hundred fifty meters) in front of the vehicle C1 according to the vehicle information (step S335). When it is determined that there is another vehicle (e.g., the vehicle C3) within one hundred and fifty meters ahead of the vehicle C1, the control module of at least one of the vehicle condition display apparatuses 100_1 to 100_3 controls the light-emitting indication module of the vehicle condition display apparatus to which the control module belongs to continuously display a third color (e.g., green) (step S337). In this example, the control module of the vehicle condition display device 100_2 controls the light-emitting indication module 14_2 to continuously display green.
Then, the vehicle detection modules of the vehicle condition display apparatuses 100_1 to 100_3 may also determine whether there are other vehicles within a first distance (e.g., within fifty meters) behind the vehicle C1 according to the vehicle information (step S339). When it is determined that there is another vehicle (e.g., the vehicle C2) in fifty meters behind the vehicle C1, the control module of at least one of the vehicle condition display devices 100_1 to 100_3 controls the light-emitting indication module of the vehicle condition display device to which the control module belongs to periodically flash to display the first color (e.g., flash red at an interval of 3 seconds) (step S341). In this example, the control module of the vehicle condition display device 100_2 controls the light-emitting indication module 14_2 to periodically flash red to make the driver of the vehicle C1 know that there is a vehicle behind the vehicle C1 at fifty meters.
When it is determined in step S339 that there is no other vehicle behind the vehicle C1 within fifty meters, the vehicle detection module of one of the vehicle condition display apparatuses 100_1 to 100_3 may determine whether there is another vehicle behind the vehicle C1 within a second distance (e.g., within one hundred meters behind) according to the vehicle information (step S343). When it is determined that there is another vehicle (e.g., the vehicle C2) within one hundred meters behind the vehicle C1, the control module of at least one of the vehicle condition display devices 100_1 to 100_3 controls the light-emitting indication module of the vehicle condition display device to which the control module belongs to periodically flash to display the second color (e.g., flash orange at an interval of 3 seconds) (step S345). In this example, the control module of the vehicle condition display apparatus 100_2 controls the light-emitting indication module 14_2 to periodically and flashing to display orange color to make the driver of the vehicle C1 know that there is a vehicle in fifty to one hundred meters behind the vehicle C1.
When it is determined in step S343 that there is no other vehicle behind the vehicle C1 within one hundred meters, the control module of at least one of the vehicle condition display apparatuses 100_1 to 100_3 controls the light-emitting indication module of the vehicle condition display apparatus to which the control module belongs to continuously display the third color (for example, green) (step S347). In this example, the control module of the vehicle condition display device 100_2 controls the light-emitting indication module 14_2 to continuously display green to make the driver of the vehicle C1 know that there is no vehicle within one hundred meters behind the vehicle.
In addition, when it is determined that there is no other vehicle (e.g., the vehicle C3) within one hundred fifty meters ahead of the vehicle C1, the control module of at least one of the vehicle condition display apparatuses 100_1 to 100_3 controls the light-emitting indication module of the vehicle condition display apparatus to which the control module belongs to continuously display green (step S349).
It should be noted that after step S309, step S313, step S315, step S325, step S329, step S331, step S341, step S345 and step S347 are completed, step S301 is executed again to repeatedly execute the process of fig. 4.
In this embodiment, the predetermined first distance is shorter than the second distance, and the second distance is shorter than the third distance. In addition, the determination of whether the target vehicle approaches another vehicle within the preset distances may be calculating a linear distance between the vehicles on the same lane, or calculating a projection distance on different lanes.
In the first embodiment of the present invention, the flow of fig. 4 is to preferentially consider a shorter distance (e.g., the aforementioned first distance) to preferentially determine an emergency situation. However, in the second embodiment of the present invention, the vehicle condition display method can also sequentially determine from large to small according to the distance.
[ second embodiment ]
Fig. 6 is a flowchart of a vehicle condition displaying method according to a second embodiment of the invention.
Referring to fig. 5 and 6, it is assumed that in the initial state, when no vehicle is running on the lane, the vehicle condition display devices 100_1 to 100_3 are set to continuously display the third color (e.g., green). Once the vehicle passes through one of the vehicle condition display apparatuses 100_1 to 100_3, the vehicle detection module of one of the vehicle condition display apparatuses 100_1 to 100_3 may analyze the vehicle information (e.g., captured images of the road and the vehicle operation condition) (step S401) and perform the subsequent steps, for example, the vehicle detection module of one of the vehicle condition display apparatuses 100_1 to 100_3 may determine the sequence of the vehicle according to the vehicle information. In the embodiment of fig. 6, the vehicle detection modules (e.g., the servers at the rear end) of the vehicle condition display apparatuses 100_1 to 100_3 can determine whether there are other vehicles within a third distance (e.g., one hundred fifty meters) in front of the target vehicle (e.g., the vehicle C1) according to the vehicle information (step S403). When it is determined that there is no other vehicle in front of the vehicle C1 within one hundred and fifty meters, the control module of at least one of the vehicle condition display devices 100_1 to 100_3 controls the light-emitting indication module of the vehicle condition display device to which the control module belongs to continuously display a third color (e.g., green) (step S405).
