The database D2 can be stored in the second device processing unit 131, or stored in A storage (not shown) electrically connected to the second device processing unit 131 .

The requesting device 110 is, for example, a mobile phone, a desktop computer or a notebook computer of the requester. After an event occurs, the requester can send the evidence request R1 , the event occurrence location P1 and the occurrence time T1 to the server 120 through the first device processing unit 111 . The event is, for example, a traffic accident, such as a vehicle collided while the vehicle is running or a vehicle is slid while the vehicle is stationary. The aforesaid traffic accidents can happen to the requester itself, but also can happen to people related to the requester, such as relatives or friends of the requester. After receiving the evidence request R1, the server 120 searches several driving trajectories DT for a driving trajectory DT' that matches the occurrence location P1 and the occurrence time point T1. Then, the server 120 sends an image file request R2 to the driving image recording device 130 corresponding to the driving track DT', so as to request an image that can clarify the truth of the accident.

The following is a further description of the process of the method for requesting auxiliary evidence based on the driving track in the embodiment of the present invention with FIG. 2 .

In step S210 , the requesting device 110 sends out the evidence request R1 and the occurrence location P1 and the occurrence time T1 of the event. For example, after the event occurs, the first device processing unit 111 of the requesting device 110 sends the evidence request R1, the place of occurrence P1 and the time T1 of the event to the server communication unit 122 of the server 120 through the first device communication unit 112 to request to record the image of the event occurrence process.

In step S220, after receiving the evidence request R1, the data search unit 123 of the server 120 searches several driving trajectories DT for a driving trajectory DT' that matches the occurrence location P1 and the occurrence time T1. If there is no driving trajectory matching the occurrence location P1 and the occurrence time point T1 among these driving trajectories DT, the server 120 sends a message indicating "No There is a message matching the search conditions" to the requesting device 110 .

The driving image recording device 130 is, for example, configured in a vehicle, such as a taxi, a public transport, a taxi, a private car, or other vehicles traveling on the road. The GPS signal receiving unit 134 of each driving image recording device 130 can receive the GPS signal. The driving track recording unit can obtain the driving track DT of the vehicle from the GPS signal, and store the driving track DT in the database D2. The second device processing unit 131 can transmit the driving track DT to the server 120 through the second device communication unit 132 by wired or wireless communication technology. After the server 120 receives the driving track DT, it can store the driving track DT in the database D1. As long as the driving image recording device 130 keeps running, the server 120 will continue to receive the latest driving track DT from each driving image recording device 130 . In one embodiment, the driving image recording device 130 uploads its latest driving trajectory DT to the server 120 synchronously.

In addition, when the vehicle is running or stationary, the camera 133 of the driving image recording device 130 captures the driving image DI, and stores the driving image DI in the database D2. In one embodiment, the sound sensing unit 136 of the driving image recording device 130 can sense whether an ambient sound corresponds to an event. When the ambient sound matches the event, the camera 133 records the driving image DI captured by the event as a driving image file DF for emergency storage. In detail, when the sound sensing unit 136 detects a sound similar to a traffic accident (such as collision sound, sudden brake tire friction sound, etc.), the camera 133 starts to record the driving image DI captured by the event as a driving image file DF, and stores the driving image file DF in the database D2. The subsequent driving image DI captured by the camera 133 will not overwrite the driving image file DF, so the normally reserved driving image file DF can be used as a future To clarify the truth of the accident (if any).

In step S230, the server processing unit 121 of the server 120 sends an image file request R2, and sends the image file request R2 to the driving image recording device 130 matching the driving track DT' through the server communication unit 122.

In another embodiment, after receiving the image file request R2 from the server 120 (step S230), the driving image recording device 130 can search the recorded driving image DI for the driving image DI that meets the occurrence time point T1 and the occurrence location P1 of the image file request R2, or extract a segment that matches the occurrence location P1 and the occurrence time point T1 (for example, 10 seconds before or after, longer or shorter) and store it as a driving image file DF.

In step S240, the driving image recording device 130 that receives the image file request R2 can automatically or under the operation of the requester send the driving image DI or the driving image file DF to the server 120. The driving image DI includes the driving image matching the occurrence location P1 and the occurrence time point T1.

In step S250, after receiving the driving image DI or the driving image file DF, the data verification unit 124 of the server 120 verifies whether the driving image DI or the driving image file DF is an original image file. For example, the data verification unit 124 judges whether the driving trajectory DT at the same time point T1 is consistent with the hash code (Hash code) of the driving image file DF. If they are consistent, it means that the driving image file DF has not been tampered with (confirm that the driving image file DF is the original image file). If not, it means that the driving image file DF may have been tampered with (the driving image file DF is not an original image file), so the server 120 will not adopt it (step S255), but the data verification unit 124 may also mark the driving image file DF as a non-original file, and then the requester decides whether to adopt it.

In step S260, the privacy protection unit 125 of the server 120 performs a privacy process on the driving image file DF. For example, the privacy protection unit 125 of the server 120 blurs the face, the license plate and/or other parts related to personal privacy in the content of the driving image file DF through the image processing unit 126 . The privacy protection unit 125 can also set permissions for the driving image file DF. For example, restrict the viewing authority for general objects, let general objects watch the blurred driving image file DF (so that general objects cannot distinguish the images involving personal privacy in the image), but provide the original driving image file DF (images without privacy processing) for specific objects, such as impartial third parties, police agencies, judicial agencies, etc. In another embodiment, the privacy processing on the driving image file DF can also be performed by the driving image recording device 130 or the requester.

In step S270 , the server processing unit 121 of the server 120 transmits the privacy-processed driving image file DF to the requesting device 110 through the server communication unit 122 . The display unit 113 of the requesting device 110 can play the driving image file DF, so that the requester can confirm whether the driving image file DF has images of recorded events. In this step, the server 120 may not send the driving image file DF to the requesting device 110, but sends a notification message (not shown) to the requesting device 110, informing the requester of the requesting device 110 that the event-related driving image file DF has been obtained. At this time, the requester can contact the above-mentioned specific object, such as the police agency, to confirm whether there is an image corresponding to the occurrence location P1 and the occurrence time point T1 recorded in the driving image file DF.

In another embodiment, after step S250, the process may directly enter step S270. That is, the server 120 does not perform privacy processing on the driving image file DF, and directly transmits the driving image file DF to the requesting device 110 .

To sum up, although the present invention has been disclosed by the above embodiments, it is not intended to limit the present invention. Those skilled in the art of the present invention can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be defined by the scope of the appended patent application.
