The above and other features and advantages of the present invention will become more apparent from the detailed description of the exemplary embodiments illustrated in the accompanying drawings in which: FIG. 1 is a block of an anti-collision warning system according to an embodiment of the present invention. Figure.

2A is a first schematic diagram of a collision avoidance warning system in accordance with an embodiment of the present invention.

2B is a second schematic diagram of a collision avoidance warning system in accordance with an embodiment of the present invention.

Figure 3 is a flow chart showing the steps of the bumper warning method according to an embodiment of the present invention.

As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items. When the statement of "at least one of" is prefixed to a list of components, The entire list of components is not an individual component of the list.

Please refer to FIG. 1, which is a block diagram of an anti-collision warning system according to an embodiment of the present invention. The anti-collision warning system 100 is used for one mobile device 51 in the mobile device. In the embodiment, the mobile device 51 is implemented by using a smart phone. However, the mobile device 51 may also include a smart glasses. Or a tablet.

The collision avoidance warning system 100 includes a first image capturing unit 10, a second image capturing unit 20, a warning prompting unit 30, and a processing unit 40. The first image capturing unit 10 and the second image capturing unit 20 may be two lenses having the same or different resolutions, and the first image capturing unit 10 and the second image capturing unit 20 are disposed opposite to each other. The first image capturing unit 10 and the second image capturing unit 20 can capture the front image of the same line of sight of the user. The warning prompt unit 30 can include a speaker or a touch output screen, and the processing unit 40 can include a central processing unit.

The first image capturing unit 10 and the second image capturing unit 20 are configured to capture one of the main image 53 and an auxiliary image 54 of the surrounding environment (not shown). The warning prompting unit 30 is configured to issue an alert message 55, wherein the alert message 55 includes an audible alert message, an image alert message, or a combination thereof. The processing unit 40 is configured to combine the main image 53 and the auxiliary image 54 to generate a three-dimensional image 57 having a depth 56. When the mobile device 51 is in a moving state, the depth 56 in the three-dimensional image 57 is less than a threshold value. At 58 o'clock, the processing unit 40 controls the warning prompting unit 30 to issue a warning message 55 to prompt the user.

In detail, the mobile device 51 can pre-categorize and store the obstacle images commonly seen on the road, such as stones, walls, steps or pedestrians. When the processing unit 40 generates the three-dimensional image 57, an image recognition can be performed to identify When the warning message unit 30 sends a warning message 55 to the user, the obstacle can be displayed at the same time to provide the user with a better information.

Please refer to FIG. 2A and FIG. 2B , which are a first schematic diagram and a second schematic diagram of an anti-collision warning system according to an embodiment of the invention. The first image capturing unit 10 and the second image capturing unit 20 of the embodiment are disposed on the surface of the screen relative to the mobile device 51. When the user holds the mobile device 51 and is in a moving state, the current time An image capturing unit 10 and a second image capturing unit 20 continuously capture the surrounding environment 52 continuously to generate a plurality of main images (not shown in the figure) and an auxiliary image (not shown in the figure), and the action The device 51 also calculates a depth 56 of the mobile device 51 to the surrounding environment 52 based on the plurality of primary and secondary images.

Further, the depth 56 of the computing mobile device 51 to the surrounding environment 52 can be performed by a background program that does not display any information on the screen of the mobile device 51 during normal operation. As shown in FIG. 2A, when the depth 56 is greater than the threshold value 58 set by the user, the distance between the current user and the surrounding environment 52 is a safe distance, and the user can normally use the mobile device 51. Any application, when the depth 56 is less than the threshold value 58 set by the user, as shown in FIG. 2B, indicating that the distance between the current user and the surrounding environment 52 is a dangerous distance, and the warning prompt unit (not shown) In the figure, a warning message 55 can be sent to the user, or the application being used by the user can be directly closed, so that the user's attention can be forcibly transferred to the surrounding environment 52, thereby reducing the user and the surrounding environment. A collision is generated to increase the safety of the user when operating the mobile device 51.

It is further explained that the threshold value 58 can be proportional to the moving speed of the mobile device 51, and the user can adjust the moving speed of the individual to set the threshold value 58 so that the collision warning system 100 is close to different users. demand.

Please refer to FIG. 3, which is a flow chart of the steps of the anti-collision warning method according to an embodiment of the present invention. The anti-collision warning method is used in the mobile device 51 of the above-mentioned 2A and 2B, which has a first image capturing unit 10 and a second image capturing unit. 20. A processing unit and a warning prompt unit, the bump warning method comprises the following steps.

Step S1 executes an application on the mobile device to enable the first image capturing unit and the second image capturing unit.

Step S2 captures a main image and an auxiliary image of a surrounding environment by using the first image capturing unit and the second image capturing unit. As shown in FIG. 2A, the resolution of the first image capturing unit 10 can be higher than or equal to the resolution of the second image capturing unit 20, and the main image (not shown in the figure) and the auxiliary image (not shown) Shown in the figure) is continuously generated.

Step S3 combines the main image and the auxiliary image by the processing unit to generate a three-dimensional image having a depth.

In step S4, when the depth is less than a threshold, the processing unit controls the warning prompting unit to issue a warning message. As shown in FIGS. 2A and 2B, by continuously combining the main image (not shown) and the attached image (not shown) to calculate the depth 56 of the mobile device 51 to the surrounding environment 52, the user can A threshold value 58 is set on the mobile device 51. When the depth 56 is less than or equal to the threshold value 58, an alert message 55 is sent by the alert notification unit.

It can be seen from the above that the anti-collision warning method and system thereof of the present invention can warn whether the device or the obstacle is too close to the front object when the mobile device is operated, thereby preventing the user from colliding with the user, thereby increasing the safety of the user when operating the mobile device. Sex.

The present invention has been particularly shown and described with reference to the exemplary embodiments thereof, and it is understood by those of ordinary skill in the art Various changes in form and detail can be made in the context of the category.
