Embodiment Construction

[0054] The preferred embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0055] The jitter phenomenon mainly occurs in the process of image analysis of the lens. When the key point information of the image is not enough, the analyzed coordinate position and the rotation direction Euler angle have a relatively large error. The coordinate position calculated in different frames is The Euler angle of the rotation direction is quite different. When these coordinate positions and the Euler angle of the rotation direction are directly assigned to the 3D model, it will cause the 3D model to shake significantly.

[0056] Such as figure 1 As shown, a method for improving the jitter of a 3D model includes the following steps:

[0057] Step S1: Identify the target image according to the key point information;

[0058] Analyze and process the target image through Qualcomm's Vuforia SDK, extract the key point information ...

Abstract

The invention provides a method and a device for improving the shake of a 3D model. The method comprises the following steps: S1, identifying a target image according to information of a key point; S2, acquiring a coordinate position and a eulerian angle in the rotating direction of the target image; S3, calculating a target coordinate position and a eulerian angle in the rotating direction of the 3D model according to the coordinate position and the eulerian angle in the rotating direction of the target image as well as the current coordinate position and the eulerian angle in the rotating direction of the 3D model; and S4, moving the 3D model to the target coordinate position and the eulerian angle in the target rotating direction. The method can obviously improve the shake of the model in an identification process, to effectively enhance the user experience of a product.

Description

Technical field [0001] The invention relates to the field of jitter processing, and in particular to a method and device for improving the jitter of a 3D model. Background technique [0002] In the existing AR early education products on the market, some of the recognized models will more or less shake, especially when the recognition image is relatively simple or the camera lens is close to the recognition image. More significant. Existing products recognize the target image through key points, and after identifying the target image, calculate the coordinate position and rotation direction Euler angle of the target image, and assign these coordinate positions and rotation direction Euler angles to the corresponding 3D model. The 3D model will move and rotate following the target image. It can be seen that there will be obvious jitter during the recognition process. [0003] Model jitter will cause a relatively poor user experience. The target users of AR early education product...
