Description

File attribute generation method including location information and related driving record device

The present invention relates to a file attribute generation method, and more particularly to a file attribute generation method for obtaining location information by using a positioning module and map information by using an image file recorded by a driving recording device.

The driving recorder and the satellite navigation device are equipped with the vehicle electronics commonly used in today's vehicle driving. Among them, the driving record device is mainly used to record the scene in front of the vehicle when traveling, and when an accident occurs, the incident content recorded in the driving record device can be used to clarify the accident responsibility of the accident. The satellite navigation device mainly obtains the coordinates of the current location of the vehicle through the Global Positioning System (GPS), and combines the map information in the satellite navigation device to indicate the route of the vehicle driving through a display screen, thereby guiding the vehicle to drive. Go to the destination you want to reach. At present, there are electronic products that integrate the above-mentioned driving recording device and satellite navigation device, that is, in a single product, which includes a photographic component of a driving recording device, and also has GPS and map information of a satellite navigation device. And selectively display related information and pictures through the same screen.

Please refer to FIG. 1(A) and FIG. 1(B), which are diagrams and methods for browsing image files in the conventional driving recorder. FIG. 1(A) is a schematic diagram of the video file browsing directly on the driving recording device. Generally speaking, due to the limitation of the size of the display screen 10 of the driving recording device, the image file is mostly replaced with the display file name in the manner of thumbnail 11 presentation. In addition, the time information 12 of the image file can also be displayed on the screen of the driving record device, such as the time record of the image file recording, or the length of the image file record. In addition, please refer to FIG. 1(B), which is a schematic diagram of a file browsing of a video file of a conventional driving recorder using a platform such as a personal computer. The browsing format of the image file on the personal computer generally depends on the operation system of the personal computer, and FIG. 1(B) shows the file browsing mode presented when the image file is displayed in the ^Windows® operating system produced by Microsoft Corporation. As shown in the figure, when the image file list is presented by a personal computer, it usually includes a plurality of basic fields, such as a file name 20, a modified (recording) date 21, and a file size 22. The naming method of the file name 20 is usually arranged in a serial number manner, and the English name preset by the manufacturer of the driving record device is combined with the aforementioned serial number to form a complete file name 20.

As described above, in the file browsing mode of the conventional driving recording device, when the number of digital image files in the storage medium of the driving recording device is increased, it takes time-consuming work to search for a specific file. For example, when a user wants to find a specific image content from a plurality of image files, for example, a video file that runs through a specific route, it is necessary to use the built-in driving device or the playback software in the personal computer operating system to open all of them separately. Image archive until you find the desired movie passage. However, similar actions are not only time-consuming and inefficient, but the main reason is that the file name of the digital image file usually has no meaning, and the corresponding image content cannot be displayed. Although the user can change the file name of the corresponding digital image file by means of the file name modification, it is a time-consuming and laborious task for a large amount of files.

The invention firstly provides a driving recording device, which mainly comprises a computing module for controlling operation of other units; a camera function module for intercepting images; and an archive attribute generating module for writing position information information Among the image files. The file attribute generation module includes a positioning module and a map information. After obtaining the instantaneous position coordinates through the positioning module, the corresponding position information is obtained in the map information. The driving recording device further includes a control interface module for performing internal function setting of the driving recording device.

The present invention further provides a method for generating a file attribute including location information, comprising the steps of: capturing an image, capturing a current position coordinate corresponding to the image, converting the captured position coordinate into position information, and determining whether it is a timed loop recording mode. If the result of the determination is "Yes", the location information is formed into a file attribute and added to the image to complete the image file creation; if the determination result is "No", the position information is detected to be changed, and when the detection result is "Yes" When the connection is completed, the current image file recording step is completed, and when the detection result is "No", the corresponding position coordinates of the image are continuously captured.

The difference is that the driving record device 200 is only configured with the positioning module 230, and is mainly used to obtain an instantaneous position coordinate, for example, when the positioning module 230 is a global position system (GPS). The position coordinates are the GPS coordinate values. The driving record device 200 first temporarily adds the position coordinate to the image file acquired by the camera function module 220 and processed by the computing module 210, and then stores the image file in the storage module 240. The storage module 240 has the same properties as the storage module 140 described above, and details are not described herein. The driving record device 200 can communicate with the electronic computer 400 through a connection method 300, and the connecting party The type 300 may include a wired or wireless connection type, wherein the wired connection type may include, but is not limited to, a Universal Serial Bus (USB), or a wired network, etc., and the wireless connection type may include, but is not limited to, include : Bluetooth, WiFi wireless network, etc. The main feature of the computer 400 described in this embodiment is that the computing capability of the computing module 410 is greater than the computing module 210 of the driving recorder 200, and the possible types of the computer 400 include, but are not limited to, individuals. Computers, laptops, tablets, or smart phones. In the drive recording device 200 and the electronic computer 400, the necessary hardware/software interface is disposed according to the type of the connection method 300, and details are not described herein.

The electronic computer 400 includes an archive attribute generation module 430 including map information 431. After acquiring the image file with the position coordinates added to the storage module 240 of the bicycle recording device 200 by the connection method 300, the position coordinates in the image file are compared by the file attribute generation module 430 in the map information 431, thereby obtaining the The location information of the image file is finally added to the original image file through the computing module 410, and the image file with the location information tag is stored in the storage module 420, or alternatively The image file is passed back to the driving record device 200. In another preferred embodiment of the present invention, the file attribute generation module 430 can also be integrated into the operation module 410.

The location coordinates in the image file of 200 are compared with the content of the map information 431, thereby obtaining the location information of the image file, and finally adding the location information to the original image file.

In the above embodiment, the driving capability of the driving record device is generally limited, and the map information occupies a large storage space and is difficult to obtain. Therefore, the positioning module 230 of the driving recording device 200 first obtains the position of the image file. After the coordinates, the electronic computer 400 with better computing power and large storage space performs a conversion procedure of the position coordinates and the corresponding position information. In this way, the requirement of the computing capability of the computing module 210 in the driving recording device 200 can be reduced, and the performance of the image recording can be avoided.

In another preferred embodiment of the present invention, the positioning module 230 can also be disposed in the file attribute generation module 430 of the electronic computer 400, that is, the file attribute generation module 430 of the electronic computer 400 performs device positioning by itself. After the location information is generated, the location information is transmitted to the driving record device 200 through the computing module 410, and the location information generated by the computer 400 is combined into the image file by the computing module 210.

Generally speaking, the recording of the driving recording device mostly adopts the recording mode of the cyclic recording, which means that the fixed recording time, for example, every 5 minutes, 10 minutes, etc., forms separate image files. However, during the above recording time, the vehicle may travel through more than one single road, that is, the location information generated by the archive attribute generating module 130, 430 in a fixed time may be a plurality of pieces of information. In a preferred embodiment of the present invention, when a vehicle equipped with the driving recording devices 100 and 200 according to the present invention travels through a plurality of roads in a fixed time, all the position information will be sequentially displayed in a single image file. Among the file attributes, for example, "Road A, Road B, Street C". According to another preferred embodiment of the present invention, when the file attribute generating module (for example, the driving record device 100 of the foregoing embodiment) is disposed on the driving record device, the location information of the current vehicle can be changed. Whether or not to determine whether to restart the access behavior of another image file. In this way, the video file recording mode is not a fixed recording time, but It is determined by detecting whether the position information of the current driving is changed or not, and the file attribute of each image file only contains a single or a fixed number of pieces of position information. In addition, it is also possible to selectively add vehicle travel direction information and travel distance to the file attributes, such as "Road A, North, 5km". In addition, the location information may include higher-level and/or lower-level street information, such as: country, city, township/town/district, road section, lane, and etc., and whether the file attribute is for the upper position and The detailed information of the location information can be set by the vehicle's drive recorder or by the user through the control interface module or even through the relevant software of the computer.

Next, the above-described file attribute presentation method and pattern of the present invention will be described with reference to FIGS. 4(A) and 4(B). Referring first to FIG. 4(A), the window 500 is a display screen of an electronic device such as a driving recorder or a smart phone. The control interface 510 is mainly used to provide a user file browsing control, which may be a part of the window 500 (for example, when the display screen is a touch panel), or may be a physical button design, which is not limited by the present invention. As shown in the figure, when the file attribute of the location information is attached to the image file, the original file name of each image file can be selectively hidden in the window 500, and the file attributes are displayed instead, including, for example, thumbnails and access times. And location information, etc. Fig. 4(B) shows the file presentation mode in the general computer operating system with the image file attached with the location information file attribute. When the image file is imported into the personal computer via the driving record device, as in the foregoing prior art, in addition to selectively including a plurality of basic fields, such as file name 60, modification (recording) date 61, and file type 62. In addition, an archive attribute field for displaying location information included in the image file is also included, such as the street 63 shown in FIG. 4(B). Regardless of the driving image file browsing mode directly on the driving record device, the smart phone, or the personal computer, the file attribute display content with the location information is as described in the above embodiment, and no longer Said.

The file attributes mentioned in the above preferred embodiments of the present invention generally refer to all information that can be used for a particular file or description file feature, including but not limited to file names, file tags, tags, features, information fields, and the like. However, it must be considered that the file name must have unique and non-repeatable characteristics in the same data structure of the operating system. Therefore, if the location information is used as the implementation method of the image file name, it must consider adding other unique information, such as running water. Number or time information, and the image file name presented may be "Street A-20130101 1200".

Next, please refer to FIG. 5. FIG. 5 is a flow chart of a file attribute generation method including position information according to the present invention, which is described in detail as follows:

Step 700: Start.

Step 710: Capture an image. The content of this step mainly utilizes the camera function module of the driving recorder to capture the external image of the vehicle.

Step 720: Capture the instantaneous position coordinates of the corresponding image. The instant position coordinates can be connected to the positioning module built in the driving recorder, or the driving recording device can be connected to other electronic devices with positioning functions through wired or wireless means, for example: satellite navigation device, smart phone, tablet computer , a notebook computer, etc., and through the electronic device to instantly provide the location coordinates of the image.

Step 730: Convert the captured position coordinates into position information. This step needs to be achieved by combining the map information. When the positioning module is a global position system (GPS), the obtained position coordinate is the GPS coordinate value. After obtaining the position coordinates corresponding to the image through the positioning module, the location information corresponding to the position coordinates can be obtained in the map information 132.

Step 740: Determine whether it is a timed loop recording mode? Means to be the invention When the proposed driving recording device uses a fixed recording time to form separate image files, when the vehicle equipped with the driving recording device travels through a plurality of roads within a fixed time, all the position information will be displayed in the file attribute of the single image file. This section is the same as the foregoing embodiment, and will not be described again. When the determination result is "YES", the connection is made to step 750; if the determination result is "NO", then step 760 is connected.

Step 750: Form the location information into an archive attribute and attach it to the image to complete the image file creation. In another preferred embodiment of the present invention, the content of step 750 can be achieved by an electronic device other than the driving record device, that is, the driving path device only provides the image file without the location information tag, and then uses other electronic devices. The location coordinates corresponding to the image file are combined with the map information to obtain the corresponding location information, and then the obtained location information is added to the image file in the form of the file attribute to complete the creation of the image file. Electronic devices may include satellite navigation devices, smart phones, tablets, notebooks, and the like. In addition, the process of combining the image file location coordinates with the map information to obtain the corresponding location information, and the file attributes are attached to the image files, etc., can also be achieved by executing a software program installed in the electronic device. As described in the foregoing embodiment, the location information may be directly added to the image file in addition to the file attribute type, and may be directly presented in the file name of the image file. After step 750 is completed, step 700 is continued to initiate the creation of the next image file.

This step is suitable for when the file attribute generation module is configured on the driving record device, the driving record device can immediately detect the change of the position information, thereby starting the recording process of the new image file. When the detection result is "Yes", that is, the location information has been detected to have changed, the connection step is Step 750 to complete the current image file recording, and start the next image file creation process; if the detection result is "No", that is, the detection location information does not change, then connect to step 720 to continuously capture the image. Corresponding position coordinates.

In another preferred embodiment of the present invention, the content of step 740 can be further ignored, that is, the content of step 750 and step 760 can be followed immediately after step 730. The creation of the image file can simultaneously determine whether to open a new image file depending on whether the location information is changed or not, or whether the set recording time is reached. As a result, the content of the determination in step 740 can be ignored.

In summary, the present invention mainly provides a file attribute of an image file, that is, the location information is used as the file attribute of the image file recorded by the driving record device, or the location information is used as the file name of the image file. Compared with the conventional image file browsing method, through the file attribute content proposed by the present invention, the user can efficiently and quickly search for and obtain the required image file from a large number of image files.

While the present invention has been described in its preferred embodiments, the present invention is not intended to limit the invention, and the present invention may be modified and modified without departing from the spirit and scope of the invention. The scope of protection is subject to the definition of the scope of the patent application.
