Problems solved by technology

[0002] At present, the terminal reads video frames from the camera of the ios device configured on the terminal through the AR kit, processes each frame of pictures and obtains feature points, and processes the determined feature points to obtain the anchor point of the AR plane. After obtaining the anchor point of the AR plane, the user needs to manually confirm the determined anchor point of the AR plane, which is cumbersome to operate
In addition, before the anchor point is obtained, the solution requires the user of the handheld terminal to hold the terminal for a long time and not shake the terminal when shooting the AR plane. However, the user continues to hold the terminal for shooting, which will easily cause the user to feel tired , poor user experience

Abstract

The invention discloses a method for determining the position of a target point and a terminal, and the method comprises the steps of generating a first ray according to the obtained position of an anchor point of an AR plane, the position of a camera which is used for shooting the AR plane and the direction of the center line of a shooting area of the camera; judging whether the first ray is intersected with the AR plane or not; if yes, determining the position of an intersection point of the first ray and the AR plane, wherein the intersection point is the target point. By adopting the method and the device, the rendering of the pixel occupied by the target point in the AR plane can be quickly completed according to the obtained anchor point of the AR plane.

Description

technical field [0001] The present application relates to the field of augmented reality (Augmented Reality, AR) technology, and in particular to a method and terminal for determining the position of a target point. Background technique [0002] At present, the terminal reads video frames from the ios device camera configured on the terminal through the AR kit, processes each frame of pictures and obtains feature points, and processes the determined feature points to obtain the anchor point of the AR plane. After the anchor point of the AR plane is obtained, the user needs to manually confirm the determined anchor point of the AR plane, and the operation is cumbersome. In addition, before obtaining the anchor point, the solution requires the user of the handheld terminal to hold the terminal for a long time and not shake the terminal when shooting the AR plane. However, the user continues to hold the terminal for shooting, which will easily cause the user to feel tired , po...
