Problems solved by technology

[0003] However, although parents can see the real-time location of their children, the positioning data may be inaccurate due to equipment or positioning signals
When there is a problem with the device positioning data, although the parents can see the child's location, the child's location seen by the parents may not be consistent with the child's actual location
That is to say, parents cannot accurately judge whether there is a problem with the location of the child they see
[0004] In addition, children may have a poor sense of direction, get lost, or encounter a fork in the road during the journey, and do not know which road to take will be safer, etc.

Embodiment 1

[0029] figure 1 It is a flow chart of the navigation method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of navigating the ward based on the positioning point. Typically, this embodiment is applicable to the situation where a child is guided along a route based on the real-time positioning data of the child. The method can be executed by a navigation device, and the device can be realized by software and / or hardware. Typically, the device can be configured in a smart device carried by the ward. The smart device may be a children's smart watch.

[0030] see figure 1 , the navigation method provided in this embodiment includes:

[0031] S110. Match the obtained positioning point with the road segment in the navigation route, so as to determine the road segment to which the positioning point belongs.

[0032] Among them, the positioning point is the positioning point of the local navigation device. Because the ward is equ...

Embodiment 2

[0070] figure 2 It is a flowchart of a navigation method provided by Embodiment 2 of the present invention. This embodiment is an optional solution proposed on the basis of the foregoing embodiments. see figure 2 , the navigation method provided in this embodiment includes:

[0071] S210. Match the obtained positioning point with the road segment in the navigation route, so as to determine the road segment to which the positioning point belongs.

[0072] S220. Determine an enclosing rectangle of the anchor point according to the road grade or road width of the road section in the navigation route.

[0073] Wherein, the surrounding rectangle of the anchor point is a rectangular area including the anchor point.

[0074] Specifically, the determination of the enclosing rectangle of the positioning point according to the road grade or road width of the road section in the navigation route includes:

[0075] Determine the drawing direction of each side in the enclosing recta...

Embodiment 3

[0101] image 3 It is a flowchart of a navigation method provided by Embodiment 3 of the present invention. This embodiment is an optional solution proposed on the basis of the foregoing embodiments. see image 3 , the navigation method provided in this embodiment includes:

[0102] S310. Match the obtained positioning point with the road segment in the navigation route, so as to determine the road segment to which the positioning point belongs.

[0103] S320. Select a valid positioning point from the positioning points according to the road section information and the positioning accuracy of the positioning points.

[0104] S330. If it is determined according to the road segment information of the valid positioning point that the valid positioning point does not match the road segment to which it belongs, and the positioning accuracy of the valid positioning point is less than or equal to the set accuracy threshold, determine the yaw.

[0105] S340. Generate yaw informati...

Abstract

The embodiment of the invention discloses a navigation method, device, equipment and medium, and relates to the technical field of map navigation. The method includes: matching the obtained positioning point with the road section in the navigation route to determine the road section to which the positioning point belongs; selecting an effective positioning point from the positioning points according to the road section information and positioning accuracy of the positioning point; Positioning point, synchronizing navigation information to monitoring terminal. The navigation method, device, equipment and medium provided by the embodiments of the present invention realize the accurate judgment of the positioning data of the child and the guidance of the correct traveling direction of the child.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of map navigation, and in particular, to a navigation method, device, equipment and medium. Background technique [0002] At present, many children's watches in China synchronize the positioning data of the watch to parents' mobile phones for parents to view, so that parents can check the current location of children in real time. [0003] However, although parents can see the real-time location of their children, the positioning data may be inaccurate due to equipment or positioning signals. When there is a problem with the device positioning data, although the parents can see the child's location, the child's location seen by the parents may not be consistent with the child's actual location. That is, parents cannot accurately judge whether there is a problem with the location of the child they see. [0004] In addition, children may have a poor sense of direction, get lost, or ...
