Detailed Description
In order to explain technical contents, structural features, and objects and effects of the present invention in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
As shown in fig. 1, in an embodiment of the present invention, a distance indicating method for a streaming media rearview mirror is disclosed, the streaming media rearview mirror is installed in a vehicle so that a driver can observe the streaming media rearview mirror when sitting on a seat, for example, the streaming media rearview mirror is installed on the top of an interior, a display screen 10 is installed on the streaming media rearview mirror, when the display screen 10 is in a closed state, the streaming media rearview mirror can be used as a reflector, the rear situation of the vehicle can be observed from the scene reflected by the streaming media rearview mirror, and when the display screen 10 is in an open state, the display screen 10 is used for displaying the rear image taken by a vehicle-mounted camera. The distance indicating method in the embodiment includes:
the display screen 10 displays a vehicle-rear image and an auxiliary mark, the auxiliary mark is superposed and displayed on the vehicle-rear image, the auxiliary mark comprises a plurality of indicating lines 100 arranged at intervals, and the plurality of indicating lines 100 are respectively used for indicating different distances between objects corresponding to the vehicle-rear images at different positions and a vehicle to which the streaming media rearview mirror belongs. For example, in fig. 1, four indication lines 100 are sequentially arranged from the lower end of the display screen 10 to the upper side at intervals, and are named as a, b, c and d, wherein the line a represents a distance 1m from the current vehicle, the line b represents a distance 3m from the current vehicle, the line c represents a distance 7m from the current vehicle, and the line d represents a distance 7m from the current vehicle. When the observation object in the image behind the vehicle is located at the line a, it indicates that the distance between the observation object and the current vehicle is 1 m. Since an object closer to the lower end of the display screen 10 is closer to the current vehicle in the rear-of-vehicle image on the display screen 10, the direction closer to the lower end of the display screen 10 is defined as a front end, and in addition, one of the foremost ones of the indication lines 100 is defined as an early warning line (line a in the drawing), that is, when the observation object in the rear-of-vehicle image is located at the position of the early warning line, the observation object is located at a safety limit distance from the current vehicle. In this embodiment, the distance indicated by the warning line may change according to the speed of the current vehicle relative to the front-most object in the rear image, so that the safety limit distance indicated on the display screen 10 may dynamically change according to the relative speed V between the current vehicle and the rear-most object (e.g., vehicle). Regarding the acquisition of the relative speed V, a first speed of the current vehicle may be acquired from a central control system of the current vehicle, and a second speed of the frontmost object in the vehicle-rear image may be calculated according to the dynamic change of the vehicle-rear image. Specifically, the distance indicated by the warning line and the relative speed V are in positive correlation. The larger the relative speed V is, the larger the distance value represented by the position indicated by the warning line is, namely the farther the safety limit distance is, the smaller the relative speed V is, and the smaller the distance value represented by the position indicated by the warning line is, namely the closer the safety limit distance is.
By the distance indicating method, the distances between the objects with different distances in the image behind the vehicle and the current vehicle can be accurately judged according to the auxiliary marks superposed and displayed on the image behind the vehicle, so that the current vehicle driver can accurately judge the rear condition of the vehicle, and the driving safety is effectively improved. In addition, because the warning lines in the plurality of indication lines 100 as the auxiliary marks can change along with the speed of the current vehicle relative to the foremost object in the vehicle rear image, the warning lines can dynamically adjust the safety limit distance according to the relative vehicle speed, thereby further improving the driving safety performance.
Specifically, the color and/or shape of the precaution line is different from the other indicator lines 100. In this embodiment, the warning line (line a) is set to be red, and the other indicating lines 100 (line b, line c, and line d) except the warning line are green.
In a further improvement, as shown in fig. 1, the warning line has a certain width to form a warning belt a0 on the mirror, the warning belt a0 includes a first boundary line a01 at the front end and a second boundary line a02 at the rear end, and the second boundary line a02 can move back and forth to change the width of the warning belt a0 along with the relative speed between the vehicle and the frontmost object in the rear-view image. In this embodiment, referring to fig. 1 and fig. 2, the larger the relative speed V, the larger the upward moving distance of the second boundary line a02, the wider the warning band a0, i.e. the farther the safety limit is set, the smaller the relative speed V, the smaller the upward moving distance of the second boundary line a02, the narrower the warning band a0, and the closer the safety limit is. Through the setting of early warning area a0, the driver can clearly know the ultimate safe distance of current vehicle, avoids causing the traffic accident because of the judgement mistake.
To further facilitate the driver to judge the position of each observed object in the image behind the vehicle, please refer to fig. 1 and fig. 2 again, the auxiliary mark further includes a plurality of digital marks corresponding to each indication line 100, and the digital marks are used for displaying the distance number corresponding to the indication line 100 of the current position. For example, a numeral symbol "1" is displayed at the a line of the indication line 100, a numeral symbol "3" is displayed at the b line of the indication line 100, a numeral symbol "5" is displayed at the c line of the indication line 100, and a numeral symbol "7" is displayed at the d line of the indication line 100. Of course, when the relative speed V becomes larger, the numerical indication displayed at a (early warning line) of the indication line 100 is changed accordingly (from 1 to 3), and at the same time, the other indication lines 100 are also followed by corresponding changes.
Another embodiment of the present invention further discloses a distance indicating system for a streaming media rearview mirror, as shown in fig. 1 and 2, a display screen 10 is disposed on the streaming media rearview mirror, the display screen 10 is used for displaying a vehicle-mounted image captured by a vehicle-mounted camera, and the distance indicating system includes: the device comprises an identification generation module and an adjustment module; the mark generation module is used for generating an auxiliary mark, the auxiliary mark is superposed and displayed on the image behind the vehicle, the auxiliary mark comprises a plurality of indication lines 100 which are arranged at intervals, the plurality of indication lines 100 are respectively used for indicating different distances between objects corresponding to the image behind the vehicle at different positions and the vehicle to which the streaming media rearview mirror belongs, and one of the indication lines 100 at the most front end is an early warning line.
