Embodiment 1

[0041] Such as image 3 As shown, it is a flow chart of the image processing method provided by Embodiment 1 of the present invention, including the following steps:

[0042] S301: After determining that the coordinate information of the set node object has changed, determine the set node according to the coordinate information before the change of the set node object, as well as the stored polygon information of each polygon object and the node information of each node object The coordinate information of each node object except the set node object in the polygon object where the object is located; wherein, the polygon information of the polygon object includes the node identification of each node object contained in the polygon object, and the node information of the node object includes node The node identification and coordinate information of the object;

[0043] S302: For any polygon object where the set node object is located, according to the changed coordinate inform...

Embodiment 2

[0065] Such as Figure 5 As shown, it is a flow chart of a method for processing a planar shop map of a shopping mall provided by Embodiment 2 of the present invention. In the following steps, the shop is equivalent to the polygon object described in Embodiment 1 of the present invention, and the shop information is equivalent to The polygon information in Embodiment 1 of the present invention includes:

[0066]S501: Establish a data model including a polygon model and a node model, the polygon model is used to store the store information of each store, and the node model is used to store the node information of each node object;

[0067] The above store information includes the store attribute information and the node identification of each node object included in the store. The store attribute information includes the store name, location, user, user phone and other information related to the store. The node information of the node object includes The node ID and coordinate...

Embodiment 3

[0075] Based on the same inventive concept, Embodiment 3 of the present invention also provides an image processing device corresponding to the image processing method in Embodiment 1 of the present invention. Since the problem-solving principle of the device is the same as that of the image processing method in Embodiment 1 of the present invention The method is similar, so the implementation of the device can refer to the implementation of the method, and the repetition will not be repeated.

[0076] Such as Image 6 As shown, it is a schematic structural diagram of an image processing device provided by an embodiment of the present invention, including:

[0077] The determination module 61 is used to determine the set node object coordinate information according to the coordinate information before the change of the set node object, as well as the stored polygon information of each polygon object and the node information of each node object after determining that the coordi...

Abstract

The invention relates to the technical field of image processing and especially relates to an image processing method and device. The method and device are used for solving problems of low processing efficiency and data redundancy storage in image processing of polygon objects in the prior art. The image processing method provided by the embodiment of the invention includes determining coordinate information of all node objects except a preset node object in the polygon object with the preset node object according to the coordinate information before the preset node object change and the stored polygon information of the polygon objects and the node information of the node objects after that the coordinate information of the preset node object changes is determined; aiming at any polygon object with the preset node object, performing rendering on the polygon object again according to the coordinate information after the preset node object change and the coordinate information of all node objects except the preset node object in the polygon object.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method and device. Background technique [0002] In the existing geographic information system (Geographic Information System, GIS), each polygon object is generally used as an independent data object for data storage or processing; for example figure 1 As shown, it is a schematic diagram of the existing data model structure. Under this data model, for each polygon object, it is necessary to store the corresponding node object data and attribute data respectively. Among them, the node object data is generally the various data contained in the polygon object. Coordinate information of node objects, for example, if a polygon object contains five node objects, then the stored node object data is the coordinate information of five node objects, (X1, Y1), (X2, Y2), (X3, Y3 ), (X4, Y4), (X5, Y5), the attribute data is generally the name information...
