一种虚拟现实环境下的展览信息观看方法，所述观看方法包括以下步骤：A method for viewing exhibition information in a virtual reality environment, the viewing method comprising the following steps:
预先采集线下展览数据，建立线下展览的三维虚拟模型，Collect offline exhibition data in advance, build a 3D virtual model of offline exhibition,
当用户佩戴VR设备，将线下展览的三维虚拟模型展出给用户，设用户正在观看的展览品为目标展品，When the user wears the VR device, the 3D virtual model of the offline exhibition is displayed to the user, and the exhibit that the user is viewing is set as the target exhibit.
当检测到用户观看目标展品的时间长度大于第一时长时，说明用户对目标展品可能比较有兴趣，采集目标展品的信息，判断是否向用户展示目标展品的详情信息，所述目标展品的详情信息包括目标展品的讲解信息，讲解信息供用户对目标展品做进一步的了解；本实施例中的展览为画展。When it is detected that the length of time that the user watches the target exhibit is longer than the first time, it means that the user may be interested in the target exhibit, collect the information of the target exhibit, and determine whether to display the detailed information of the target exhibit to the user. Including the explanation information of the target exhibit, the explanation information is for the user to further understand the target exhibit; the exhibition in this embodiment is a painting exhibition.
所述采集目标展品的信息包括：The information of the collection target exhibits includes:
采集目标展品在线下展览时的情况，并据此获取目标展品的线下关注指数w,Collect the situation of the target exhibits during the offline exhibition, and obtain the offline attention index w of the target exhibits accordingly,
所述获取目标展品的线下关注指数w包括：The offline attention index w for obtaining the target exhibit includes:
在线下展览中，设目标展品面前检测到的观众为候选观众，候选观众的总人数为Rz，In the offline exhibition, the audience detected in front of the target exhibit is set as the candidate audience, and the total number of candidate audiences is Rz,
预先将目标展品沿着水平方向平均划分成m段分展品，一般情况下，展品前面都会设置栏杆，观众观看展品都需要在栏杆界限外观看，当观众对展品比较有兴趣时，会靠近展品，所以获取每个候选观众在每段分展品前距离目标展品的距离，如果某个候选观众在某段分展品前距离目标展品的距离小于等于关注距离，说明观众对该部分的分展品有兴趣，那么该段分展品为该个候选观众的关注分展品，The target exhibits are divided into m sections in advance along the horizontal direction. In general, railings will be set in front of the exhibits. The audience needs to watch the exhibits from the outside of the railings. When the audience is more interested in the exhibits, they will approach the exhibits. Therefore, the distance between each candidate audience and the target exhibit before each sub-exhibit is obtained. If the distance between a candidate audience and the target exhibit in front of a sub-exhibit is less than or equal to the attention distance, it means that the audience is interested in this part of the sub-exhibit. Then this sub-exhibition is the sub-exhibition of the candidate audience,
计算某个候选观众对目标展品的有效指数H＝k/m，其中，k为目标展品所对应的分展品中为该个候选观众的关注分展品的个数，Calculate the effective index H=k/m of a candidate audience to the target exhibit, where k is the number of sub-exhibits that the candidate audience is concerned about in the sub-exhibits corresponding to the target exhibit,
如果某个候选观众对目标展品的有效指数大于有效阈值，那么该个候选观众为目标展品的有效观众，考虑到线下候选观众有可能是为了避让行人，所以有可能会出现离目标展品比较近的情况，所以本申请中通过有效指数来判断观众是否真正对目标展品感兴趣，当某个候选观众对目标展品的有效指数越大时，说明观众是真正对目标展品感兴趣；If the effective index of a candidate audience to the target exhibit is greater than the effective threshold, then the candidate audience is an effective audience for the target exhibit. Considering that the offline candidate audience may be to avoid pedestrians, it may appear closer to the target exhibit. Therefore, in this application, the effective index is used to judge whether the audience is really interested in the target exhibit. When the effective index of a candidate audience for the target exhibit is larger, it means that the audience is really interested in the target exhibit;
那么目标展品的线下关注指数w＝Ry/Rz，其中，Ry为目标展品的有效观众的人数。当目标展品的线下关注指数比较大的时候，说明对目标展品有兴趣的人比较多，会想要进一步了解目标展品的更多信息；Then the offline attention index of the target exhibit w=Ry/Rz, where Ry is the number of effective audiences of the target exhibit. When the offline attention index of the target exhibit is relatively large, it means that there are more people interested in the target exhibit and would like to know more about the target exhibit;
采集用户在观看目标展品的第一时长内视线信息，并据此获取目标展品的用户关注指数v，所述获取目标展品的用户关注指数v包括：Collect line-of-sight information of the user during the first period of viewing the target exhibit, and obtain the user's attention index v of the target exhibit accordingly, and the obtained user's attention index v of the target exhibit includes:
如果某个分展品为某个候选观众的关注分展品，那么该个分展品的候选指数b加1，其中，某个分展品的候选指数的初始值为0，If a sub-exhibit is the attention sub-exhibit of a candidate audience, then the candidate index b of the sub-exhibit is increased by 1, and the initial value of the candidate index of a sub-exhibit is 0,
如果某个分展品的优选指数b/Rz大于优选阈值，那么该个分展品为优选分展品，If the preference index b/Rz of a sub-exhibit is greater than the preference threshold, then the sub-exhibit is the preferred sub-exhibit,
获取优选分展品在目标展品中的所在位置，如果优选分展品在目标展品中的所在位置优选位置，那么该优选分展品为目标展品的兴趣分展品，其中，优选位置为目标展品距离靠近用户已经观看过的展品的一侧预设长度范围内的位置，例如，用户是按照从左到右的方向依次看展，那么目标展品的左侧为用户已经观看过的展品，那么目标展品中的优选位置为目标展品的左端起向右预设长度范围内位置，比如说，预设长度是展品宽度的四分之三，那么目标展品的左端起到展品宽度的四分之三处的位置均属于优选位置；本申请中通过优选分展品的所在位置进一步进行筛选得到兴趣分展品是因为，当用户向优选位置以外的位置停留时有可能是因为用户想要看下一个展览，所以通过优选位置做进一步筛选，减少后续判断用户是否需要讲解信息的误差；Obtain the location of the preferred sub-exhibit in the target exhibit. If the preferred sub-exhibit is in the preferred location of the target exhibit, then the preferred sub-exhibit is the target exhibit's interest sub-exhibit, and the preferred location is the target exhibit. The position within the preset length range of one side of the viewed exhibit. For example, if the user is viewing the exhibit in order from left to right, then the left side of the target exhibit is the exhibit that the user has already viewed, then the preferred exhibit in the target exhibit The position is within the preset length from the left end of the target exhibit to the right. For example, if the preset length is three-quarters of the width of the exhibit, then the position from the left end of the target exhibit to three-quarters of the width of the exhibit belongs to Preferred location; in this application, the sub-exhibits of interest are obtained by further screening the location of the preferred sub-exhibits because, when the user stays at a location other than the preferred location, it may be because the user wants to see the next exhibition, so the preferred location is used to do Further screening to reduce errors in subsequent judgments on whether users need to explain information;
采集用户在观看目标展品的第一时长Tz内视线停留在目标展品的所有兴趣分展品上的时间长度之和ts，那么目标展品的用户关注指数v＝ts/Tz。Collect the sum of time lengths ts that the user stays on all interest sub-exhibits of the target exhibit within the first time period Tz of viewing the target exhibit, then the user attention index v=ts/Tz of the target exhibit.
计算目标展品的综合关注指数z＝0.5*v+0.5*w，Calculate the comprehensive attention index z=0.5*v+0.5*w of the target exhibits,
如果目标展品的综合关注指数大于综合关注阈值，那么向用户展示目标展品的详情信息。If the comprehensive attention index of the target exhibit is greater than the comprehensive attention threshold, the detailed information of the target exhibit is displayed to the user.
