数智人高清面部数据产品

本数据产品在计算机中存储和组织方式采用多层次结构化设计，其核心是由超过五万张超高分辨率图像构成原始数据层。每一张图像都分配一个唯一字符串标识符作为其主关键字段，例如“characterA_expression_005_angle_L45_light_soft.png”，字段确保每一条数据记录唯一性和可检索性。与每一张图像文件直接关联的是一个JSON格式元数据文件。该元数据文件包含描述图像内容关键字段和属性，这些字段共同构成了数据集的标注体系。核心字段包括：数字人角色标识、表情类型，为预定义的枚举值，如喜悦、悲伤等、表情强度，为0到1之间的浮点数、摄像机角度，如正面、左侧45度等、光照条件，如主光、侧光、柔光等以及遮挡状态，标识是否存在头发、手部等遮挡物。此外，还包含通过算法预提取“facial_landmarks”（面部关键点坐标数组）。
上述原始数据和元数据经过特定算法处理流程后，最终生成的数据产品是二进制的DFM模型文件。模型文件集成了所有训练数据核心特征，并辅有记录着模型架构、训练迭代次数和最终性能指标的配置文件。

This data product adopts a multi-level structured design for storage and organization in computers. Its core is the original data layer composed of more than 50,000 ultra-high-resolution images. Each image is assigned a unique string identifier as its primary key field, for example, "characterA_expression_005_angle_L45_light_soft.png", which ensures the uniqueness and retrievability of each data record. A JSON-format metadata file is directly associated with each image file. This metadata file contains key fields and attributes describing the image content, and these fields collectively form the annotation system of the dataset. The core fields include: digital human character ID, expression type (predefined enumeration values such as joy, sadness, etc.), expression intensity (a floating-point number between 0 and 1), camera angle (such as front view, 45-degree left view, etc.), lighting conditions (such as key light, side light, soft light, etc.), and occlusion status (indicating whether occlusions such as hair and hands exist). In addition, it also includes the pre-extracted "facial_landmarks" (an array of facial landmark coordinates) via algorithms. After the above original data and metadata go through a specific algorithm processing pipeline, the final generated data product is a binary DFM model file. The model file integrates all the core features of the training dataset, and is accompanied by a configuration file that records the model architecture, training iteration times and final performance metrics.
