Embodiment 1

[0032] figure 1 It is a schematic flow chart of a method for determining a target image provided by Embodiment 1 of the present invention. This embodiment is applicable if the image displayed on the computer is a polyline image drawn based on a Bezier curve, and the target area to be framed is determined Afterwards, the line graph located in the target area can be determined, and then the situation of calling the line graph can be determined. The method can be executed by a device for determining the target image. The device can be implemented in the form of software and / or hardware, and the hardware can be electronic Devices, such as mobile terminals, PCs, or servers.

[0033] Before the present invention is further described in detail, the terms and terms involved in the embodiments of the present invention are described, and the terms and terms involved in the embodiments of the present invention are applicable to the following explanations:

[0034] 1) Canvas canvas: an e...

Embodiment 2

[0055] figure 2 It is a schematic flowchart of a method for determining a target image provided by Embodiment 2 of the present invention. On the basis of the foregoing embodiments, the target area is determined based on the information of the start point and the end point of the user-triggered operation, so that the user can conveniently Select the line chart in the canvas. At the same time, after the array to be processed is determined, the accuracy of the determined target point information is improved by adjusting the Bessel parameters in the target point determination model. For its specific implementation, refer to the technical solution of this embodiment. Wherein, technical terms that are the same as or corresponding to those in the foregoing embodiments will not be repeated here.

[0056] Such as figure 2 As shown, the method specifically includes the following steps:

[0057] S210. Determine the target area based on the start point information and the end point ...

Embodiment 3

[0079] image 3 It is a schematic flowchart of a method for determining a target image provided by Embodiment 3 of the present invention. On the basis of the foregoing embodiments, according to the preset Bessel parameter adjustment accuracy and Bessel parameter adjustment range, the Bessel The parameters are adjusted to obtain at least one target point information, which improves the accuracy of the finally determined line chart. Based on the target point information in different situations, the position of the Bezier curve is differentiated and judged, which further improves the accuracy and flexibility of determining the target Bezier curve and the corresponding line graph. After the target line chart is obtained, it can be processed with effects. Not only can the selected style be saved, exported or data query, but also the target line chart can be marked, so that other users can directly select the target line chart. For its specific implementation, refer to the technica...

Abstract

The embodiment of the invention discloses a method and device for determining a target image, electronic equipment and a storage medium, and the method comprises the steps: determining a target region, and determining the vertex information of the target region; obtaining to-be-selected inflection point information of each to-be-selected line graph, and determining to-be-processed inflection point information according to the vertex information and at least one piece of to-be-selected inflection point information; for each piece of to-be-processed inflection point information, obtaining control point information corresponding to the current to-be-processed inflection point information and the next to-be-processed inflection point information, and obtaining a to-be-processed array according to the current to-be-processed inflection point information, the next to-be-processed inflection point information and the control point information; and processing the current to-be-processed array through a target point determination model to obtain at least one piece of target point information, and determining a target broken line graph located in the target area according to the at least one piece of target point information and the vertex information. According to the technical scheme of the embodiment of the invention, the convenience of determining the target image and the reusability of the image are improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular, to a method, device, electronic equipment, and storage medium for determining a target image. Background technique [0002] When drawing graphics based on the computer, the canvas can be used for image drawing, for example, the histogram, line chart, pie chart, etc. can be drawn through the canvas canvas. For regular graphics, the user frame can be determined by calculating the coordinates selected graphics. [0003] When drawing a line graph based on canvas, it is mostly drawn based on Bezier curves, but when performing box selection, the computer cannot determine which one or more line graphs are selected, resulting in the inability to determine the target from the drawn graphics graphics. [0004] When the inventor implemented the technical solution based on the above method, he found the following problems: [0005] The existing technology sho...
