The embodiment of the present invention also provides an adaptive body shape data matching system for virtual reality accordingly.

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0035] See also Figure 1 As shown, an adaptive body shape data matching method for virtual reality provided by an embodiment of the present invention specifically includes the following steps:

[0036] S1: Based on the camera equipment, the body shape information of the person used for subjective evaluation of the virtual human machine is obtained;

[0037] In the embodiment of the present invention, the subjective evaluator used for the virtual human-machine is an evaluator in reality, which corresponds to the virtual human body model in the virtual reality technology.

[0038] In the embodiment of the present invention, the camera device is a virtual reality CAVE (Cave Automatic Virtual Environment) camera capture system, and the virtual reality CAVE camera capture system is used to automatically obtain the body shape information of the evaluator. The body shape information of the virtual human-machine subjective evaluator is obtained, specifically: based on the cameras set in front, behind and below the virtual human-machine subjective evaluator, the body shape information of the virtual human-machine subjective evaluator is obtained.

[0039] That is, the virtual reality CAVE camera capture system in the embodiment of the present invention includes 10 cameras, 4 of which are arranged on the upper front side of the evaluator, 2 on the lower side, and 4 on the upper and lower sides of the rear. The image information of the evaluator in the CAVE is obtained through the camera, and then the body shape information of the evaluator is obtained according to the obtained image information.

[0040] S2: According to the acquired body shape information, the key dimensions of each part in the body shape information are obtained. After the body shape information of the evaluator is obtained, several key dimensions of each part of the human body can be calculated and analyzed according to a computer program. The key dimensions are the dimensions of the parts that play a decisive role in the body shape of the human body. Specifically, the key dimensions in the embodiment of the present invention include height, sitting height, upper arm length, forearm length, shoulder width, chest thickness, etc.

[0041] S3: matching a virtual human model that meets all key dimensions in the virtual human model database;

[0042] In an embodiment of the present invention, a virtual human body model database stores multiple virtual human body models of different body types, specifically human body models of different human bodies in different countries, that is, multiple virtual human body models established corresponding to different human bodies in different countries, for example, human body models of 95% males, 50% males or 5% males, and human body models of 95% females, 50% females or 5% females in a certain country, and each human body model contains a number of key size data.

[0043] S4: Output the matched virtual human model to complete the adaptive body shape data matching. Quickly and automatically match the body shape of the evaluator to the corresponding virtual human model and automatically establish a mapping relationship, so as to realize the subjective evaluation experience related to the vehicle based on virtual reality technology and improve the ability to identify related problems.

[0044] In the embodiment of the present invention, after obtaining the key dimensions of each part in the body shape information, the method further includes:

[0045] S201: grouping the obtained multiple key dimensions, and each group includes multiple key dimensions;

[0046] S202: numbering the obtained groups in sequence based on the importance of the key dimensions. For example, for the body shape of a human body, height is the most direct influencing factor, followed by arm length, so height and sitting height can be placed in the first group, and upper arm length and forearm length can be placed in the second group.

[0047] In a possible implementation, the obtained multiple key dimensions are divided into n groups (n is a positive integer), and the groups are numbered from 1 to n in sequence according to the importance of the key dimensions, and each group includes 2 to 4 key dimensions.

[0048] In the embodiment of the present invention, matching to obtain a virtual human body model that meets all key dimensions in a virtual human body model database specifically includes the following steps:

[0049] S301: matching the key dimensions in the first group with the virtual human body model database, obtaining virtual human body models in the virtual human body model database that meet all the key dimensions in the first group, and selecting a preset number of virtual human body models that are closest to the key dimensions;

[0050] S302: matching the key dimensions in the second group with the selected virtual human models, obtaining virtual human models that meet all the key dimensions in the second group from the selected virtual human models, and selecting a set number of virtual human models that are closest to the key dimensions again;

[0051] S303: matching the key dimensions in the third group with the virtual human models selected again, obtaining virtual human models that meet all the key dimensions in the third group from the virtual human models selected again, and selecting a certain number of closest virtual human models again;

[0052] S304: Similarly, the key dimensions of all groups are matched until a virtual human model that meets all key dimensions is obtained, and finally a virtual human model that is closest to the virtual human model is selected as the matched virtual human model. It should be noted that each time the key dimensions of each group are matched, the selected virtual human model is reduced by multiples.

[0053] The above matching process is described in detail below.

[0054] The key dimensions in the first group are matched with the virtual human body model database to obtain virtual human body models in the virtual human body model database that meet all the key dimensions in the first group, and 3 (n-1) closest virtual human body models are selected therefrom; the key dimensions in the second group are matched with the selected 3 (n-1) virtual human body models to obtain virtual human body models in the selected virtual human body models that meet all the key dimensions in the second group, and 3 (n-2) closest virtual human body models are selected therefrom; the key dimensions in the third group are matched with the 3 (n-2) virtual human body models selected again to obtain virtual human body models in the selected virtual human body models that meet all the key dimensions in the third group, and 3 (n-3) closest virtual human body models are selected therefrom; and so on, after all n groups of key dimensions are matched, 1 virtual human body model is finally obtained, the body shape of the virtual human body model is closest to the body shape of the evaluator, so that a real and accurate simulation evaluation can be achieved.

[0055] The adaptive body shape data matching method of the embodiment of the present invention obtains the body shape information of the person who is used for the subjective evaluation of the virtual human machine, and then obtains the key dimensions of each part in the body shape information based on the obtained body shape information, and matches the virtual human model that meets all the key dimensions in the virtual human model database based on the matching method, and then outputs the virtual human model, quickly and automatically matches the body shape of the evaluator to the corresponding virtual human model and automatically establishes a mapping relationship, realizes data synchronous evaluation, and feeds back the subjective evaluation experience to the design data, effectively ensuring the accuracy of the subjective evaluation results of the virtual human machine.

[0065] Matching the key dimensions in the third group with the virtual human models selected again, obtaining virtual human models that meet all the key dimensions in the third group from the virtual human models selected again, and selecting a certain number of closest virtual human models again;

[0066] And so on, the key dimensions of all groups are matched until a virtual human model that meets all key dimensions is obtained, and finally a virtual human model that is closest to the virtual human model is selected as the matched virtual human model.
