Embodiments of the invention

[0022] In the following description, for purposes of illustration and description However, it will be apparent to those skilled in the art that the present invention may be practiced in other embodiments without these specific details. In other cases, province Detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the invention.

1 is a structural block diagram of a monitoring system for the number of taxi passengers according to an embodiment of the present invention. For convenience of explanation, only parts related to the present embodiment are shown.

[0024] Referring to FIG. 1, the system includes a client and a server, the server is located on the network side, and the client is located in the rental car, including a terminal, a camera, and a meter, where:

[0025] The terminal is a smart terminal device, which comprises a wireless communication module, a navigation and positioning module, a data processing module, etc., and each module uses JSON mode for communication, and the terminal can be based on a _rOC kchipp _X 2 vehicle hardware platform and an android operating system. run. In addition, the terminal further includes an intelligent algorithm module for implementing a monitoring algorithm for the number of taxi passengers. Before executing the monitoring algorithm, the module first acquires the state of the camera, and if the camera connection is abnormal, returns a corresponding error message, The algorithm is executed, and if the camera is connected normally, the monitoring algorithm for the number of taxi passengers described in the following embodiments is executed.

[0026] The camera can be a network camera (IPC) for video image acquisition at 720P or other resolutions.

[0027] The meter can output the operating status and operation data of the taxi to the terminal, wherein the operating status includes an empty vehicle state or a heavy vehicle state, and the operation data includes the driving time, the mileage and the vehicle of the taxi in the heavy vehicle state. Fee data.

[0028] FIG. 2 shows an implementation flow of a method for monitoring the number of taxi passengers provided by an embodiment of the present invention, which is described in detail as follows:

[0029] In S201, when the speed of the taxi increases from 0 to the preset speed value 吋, the control camera captures the first in-vehicle image.

[0030] In the embodiment of the present invention, the preset speed value may be configured, for example, the preset speed value is set to 40KM/H, and the speed value of the taxi is determined by setting the speed value. When the vehicle speed rises from 0 to the preset speed value 吋, it indicates that the taxi starts from the parking state to the normal driving state, during which the number of passengers in the vehicle may change, and then the control camera captures the first in-vehicle image.

[0031] In the embodiment of the present invention, once the camera captures the in-vehicle image, the in-vehicle image is parsed in the background by the image analysis algorithm to parse the number of passengers in the in-car image, and the number of passengers does not include rental. The driver himself, in the process of image analysis, will exclude the taxi located in the left front driving position in the car. Driver.

[0032] In S202, the current operating state of the taxi is obtained by the meter, and the operating state includes an empty state or a heavy vehicle state.

[0033] wherein, the empty vehicle state indicates that the taxi has not passed the meter to start the operation data statistics, and the heavy vehicle state indicates that the taxi has received the passenger currently, and the pricing is started. The operation status is manually operated by the taxi driver, usually In the case, when a passenger gets on the train and starts to calculate the price, the operation status changes to the heavy vehicle state. When the passenger arrives at the destination and gets off the vehicle, the operation status is changed to the empty vehicle state after the pricing is over.

[0034] In S203, a corresponding monitoring strategy is executed in combination with the number of passengers in the first in-vehicle image and the current operating state of the taxi.

[0035] In the embodiment of the present invention, the corresponding monitoring strategy is executed in combination with the number of passengers in the first in-vehicle image and the current operating state of the taxi. If the monitoring result is abnormal, the monitoring alarm information is sent to the server, indicating that the The taxi was suspected of operating illegally.

[0036] Specifically, the implementation of S203 includes the following two situations:

[0037] In the first case, the current operating state of the taxi is an empty vehicle state, as shown in FIG. 3, the implementation of S203 is as follows:

[0038] S301. If the number of passengers in the first in-vehicle image is greater than 0, control the camera to capture a second in-vehicle image.

[0039] If the current operating state of the taxi is an empty state, then in theory, the current number of passengers is 0, and if the analysis result of the first in-vehicle image is that the number of passengers is greater than 0, then the vehicle has a violation operation. It is possible, in order to ensure the accuracy of the monitoring results, the control camera captures the second in-vehicle image.

[0040] S302. If the number of passengers in the second in-vehicle image is greater than 0, send monitoring alarm information to the server.

[0041] If the analysis result of the second in-vehicle image is that the number of passengers is still greater than 0, then the taxi is considered to be in violation of the operation, and the monitoring alarm information is sent to the server.

[0042] In addition, in order to further ensure the correctness of the monitoring result, the acquisition of the second in-vehicle image can be achieved by multiple shootings, for example, taking an in-vehicle image every 1 minute, if the vehicle is taken three times in succession. In the internal image, the number of passengers is greater than 0, then the monitoring alarm message is sent to the server.

[0043] Case 2, the current operating state of the taxi is the heavy vehicle state, as shown in FIG. 4, the implementation of S203 is as follows [0044] S401. When the speed of the taxi increases from 0 to the preset speed value 吋, the camera is controlled to capture a third in-vehicle image.

[0045] If the current operating state of the taxi is a heavy vehicle state, then theoretically, the analysis result of the first in-vehicle image is that the number of passengers is greater than 0, and therefore, it is necessary to monitor the illegal operation of the taxi in the middle of the taxi. Phenomenon, therefore, when the speed of the taxi rises again from 0 to the preset speed value 吋, it indicates that the taxi starts from the parking state to the normal driving state, during which the number of passengers in the car may change, and then, the camera is controlled. Take a third in-car image.

[0046] S402, if the number of passengers in the third in-vehicle image is greater than the number of passengers in the first in-vehicle image

, then send monitoring alarm information to the server.

[0047] If the number of passengers analyzed in the third in-vehicle image is greater than the number of passengers parsed in the first in-vehicle image, it is considered that the taxi has a passenger carpool in the middle of the road, and the taxi is suspected of violating the operation, and the monitoring message is sent to the server.

[0048] In addition, in order to further ensure the correctness of the monitoring result, the acquisition of the third in-vehicle image can be achieved by multiple shootings, for example, taking an in-vehicle image every 1 minute, if the vehicle is taken three times in succession. In the inner image, the number of passengers is greater than the number of passengers in the first in-vehicle image, and then the monitoring alarm information is sent to the server.

[0049] Further, as an embodiment of the present invention, when the monitoring alarm information is sent to the server, the first in-vehicle image and the last photographed in-vehicle image are uploaded to the server as a determination taxi. Evidence of suspected violation of the operation.

[0050] In addition, if the monitoring alarm information is not sent to the server, the operating state of the taxi is changed from the heavy vehicle state to the empty vehicle state, and the captured in-vehicle image is deleted in the local cache to save the terminal storage. space.

[0051] In the embodiment of the present invention, the image of the interior of the vehicle is collected by the in-vehicle camera to analyze the number of passengers in the vehicle, and the change of the number of passengers in the vehicle and the current operating state of the taxi determine whether the taxi is suspected. Violation of regulations, and uploading monitoring and alarm information to the server, the monitoring results are accurate, and compared with the traditional solution of installing pressure sensors on the taxi seat, this solution does not need to increase the external hardware cost, no need to install wiring, and the maintenance cost is also large. reduce.
