Abstract

The present disclosure provides a method and system of displaying information, applied to a transparent display configured on a vehicle. The method includes: capturing an image including a target at a first time point; identifying the target in the image, so as to acquire a first relative position of the target; acquiring first identification information of the target; acquiring relative moving information between the vehicle and the target; estimating a first estimated position and first estimated time of the target that appears in a display region of the transparent display according to the first relative position of the target, the first time point and the relative moving information; and displaying prompting information corresponding to the target on the transparent display according to the first estimated time, the first estimated position of the target and the first identification information of the target.

First claim

What is claimed is:

1. A method of displaying information, applied to a transparent display configured at a side of a vehicle and implemented by a processor, the method of displaying information comprising:
identifying a user in the vehicle;
calculating a visual range of the user according to a face position or eye positions of the user;
capturing an image at a first time point, the image comprising a target;
identifying the target in the image, so as to acquire a first relative position of the target;
acquiring first identification information of the target;
acquiring relative moving information between the vehicle and the target;
estimating a first estimated position and first estimated time of the target that appears in a display region of the transparent display according to the visual range of the user, the first relative position of the target, the first time point and the relative moving information between the vehicle and the target before the target appears on the side of the vehicle;
calculating a position of the target that is projected to the display region of the transparent display according to the visual range of the user, the first relative position of the target, the first time point, the first estimated position of the target, the first estimated time and the relative moving information between the vehicle and the target; and
displaying prompting information corresponding to the target on the display region of the transparent display according to the calculated position and the first identification information of the target.

2. The method of displaying information according to claim 1 , further comprising:
estimating a plurality of relative positions of the target in the display region of the transparent display;
displaying a plurality of pieces of prompting information corresponding to the target on the display region of the transparent display according to the relative positions;
judging whether an actual position of the target is overlapped with the relative positions or not;
not displaying the prompting information corresponding to the relative positions if it is judged that the actual position of the target is overlapped with the relative positions.

3. The method of displaying information according to claim 1 , further comprising:
capturing another image at a second time point, the another image comprising the target;
identifying the target in the another image, so as to acquire a second relative position of the target;
acquiring second identification information of the target;
estimating a second estimated position and second estimated time of the target that appears in a display region of another transparent display according to the second relative position of the target, the second time point and the relative moving information between the vehicle and the target; and
displaying the prompting information corresponding to the target on the display region of the another transparent display according to the second estimated time, the second estimated position of the target and the second identification information of the target.

4. The method of displaying information according to claim 1 , further comprising:
capturing another image at a second time point, the another image comprising the target;
identifying the target in the another image, so as to acquire a second relative position of the target;
estimating a second estimated position and second estimated time of the target that appears in a display region of another transparent display according to the second relative position of the target, the second time point and the relative moving information between the vehicle and the target; and
displaying the prompting information corresponding to the target on the display region of the another transparent display according to the second estimated time, the second estimated position of the target and the first identification information of the target.

5. The method of displaying information according to claim 1 , further comprising:
estimating a second estimated position and second estimated time of the target that appears in a display region of another transparent display according to the first relative position of the target, the first time point and the relative moving information between the vehicle and the target; and
displaying the prompting information corresponding to the target on the display region of the another transparent display according to the second estimated time, the second estimated position of the target and the first identification information of the target.

6. The method of displaying information according to claim 1 , further comprising:
comparing the first relative position of the target at the first time point with the relative position of the target at another time point, so as to forecast a path of the target.

7. The method of displaying information according to claim 1 , further comprising:
acquiring relative positions of the target in a plurality of continuous frames of images; and
respectively comparing the relative position of the target of the previous frame in the plurality of continuous frames of images with the relative position of the target of the next frame, so as to judge a motion mode of the target and forecast a path of the target.

8. A system of displaying information, comprising:
a transparent display, configured at a side of a vehicle;
a first external image capturing device, configured to identify a user in the vehicle;
a speed sensing apparatus;
a processor, coupled to the transparent display, the first external image capturing device and the speed sensing apparatus, and configured to calculate a visual range of the user according to a face position or eye positions of the user,
wherein the first external image capturing device circuit is configured to capture an image at a first time point, and the image comprises a target;
the processor is configured to identify the target in the image;
the first external image capturing device is configured to acquire a first relative position of the target;
the speed sensing apparatus is configured to capture relative moving information between the vehicle and the target;
the processor is configured to estimate a first estimated position and first estimated time of the target that appears in a display region of the transparent display according to the visual range of the user, the first relative position of the target, the first time point and the relative moving information between the vehicle and the target before the target appears on the side of the vehicle;
the processor is further configured to calculate a position of the target that is projected to the display region of the transparent display according to the visual range of the user, the first relative position of the target, the first time point, the first estimated position of the target, the first estimated time and the relative moving information between the vehicle and the target; and
the processor is configured to display prompting information corresponding to the target on the display region of the transparent display according to the calculated position and the first identification information of the target.

9. The system of displaying information according to claim 8 , wherein the processor is further configured to estimate a plurality of relative positions of the target in the display region of the transparent display;
the transparent display is further configured to display a plurality of pieces of prompting information corresponding to the target on the display region of the transparent display according to the relative positions;
the processor is further configured to judge whether an actual position of the targ
