Problems solved by technology

However, the results of the fit analysis conducted by the designer according to the above method cannot be well adapted to the vast number of users, and the fit effect of the product and head shape cannot be displayed intuitively, and it is not convenient to choose different head shapes at the same time for wearing effect. Contrast, resulting in poor fit of the designed headset and poor user experience

Embodiment Construction

[0034] The present invention will be described in further detail below.

[0035] A gap measurement method for the fit analysis of headwear products, comprising the following steps,

[0036] Select the product model to be measured and the standard head shape for measurement;

[0037] Superimpose the product model on the standard head shape;

[0038] Cut the product model superimposed on the standard head shape to obtain a cross-sectional graphic;

[0039] Read profile graphics to obtain head shape contour curve and model contour curve;

[0040] Calculate the distance between any point on the contour curve of the head shape and the corresponding point on the contour curve of the model.

[0041] Specifically, firstly, a three-dimensional space is established using WebGL technology, and users can browse and interact with three-dimensional product models and standard head shapes in a browser, such as rotating, moving or zooming.

[0042] Get the product model to be tested and a...

Abstract

The invention relates to a gap measurement method for adaptability analysis of a head-mounted product, and the method comprises the following steps: selecting a to-be-measured product model and a standard head shape for measurement; superposing the product model on the standard head shape; sectioning the product model overlaid on the standard head shape to obtain a section graph; reading the profile graph to obtain a head profile curve and a model profile curve; and calculating to obtain the distance between any point of the head profile curve and the corresponding point of the model profile curve. The matching effect of the head-mounted product and the head shape can be visually displayed through the distance obtained through the calculation result. Different standard head types are replaced; different head types can be conveniently selected for wearing effect comparison; the quantized data for improving the adaptability of the head-mounted product can be provided, the situation thatthe experience is poor due to mutual interference between the head-mounted product and the head or too large gaps between the head-mounted product and the head is avoided, the user experience of the head-mounted product is effectively improved, the later availability test cost is saved, and the competitiveness of the head-mounted product is improved.

Description

technical field [0001] The invention relates to the field of adaptability analysis of headwear products, in particular to a gap measurement method for the fit analysis of headwear products. Background technique [0002] The rapid growth of the consumer market has created new demands for wearable products, and at the same time, users have higher and higher requirements for the comfort of head-wearing products. The fit of the head shape and the shape of the product determines the wearing comfort of the product to a large extent. The product design needs to be designed according to the accurate data of the head and face shape. Sex and safety are very important. A proper fit is required between them to enhance the user's comfort and make it more ergonomic. First of all, wearing unsuitable headwear products will bring poor user experience. Secondly, if wearing some protective products that are closely related to safety performance and product fit, such as bicycle helmets, etc.,...
