基于手机成像质量颜色评价的必要性，提出一种融合相机主观场景成像色彩和白平衡的自动评测方法（CIQA），以充分提取彩色图像相关特征并模拟人眼视觉感知特性来评价图像颜色。首先使用尺度不变特征变换（Scale-invariant feature transform，SIFT）与透射变换相结合的方法，标识主观图像中ColorChecker标准二十四色卡对应的位置；而后构建离差率最小二乘法模型，并采用专家赋权法和熵权法计算色彩还原和白平衡指标权重分配比例；最后，通过多指标权重值对TOPSIS（Technique for Order Preference by Similarity to an Ideal Solution）进行改进，确定各方案与典型正负理想方案的接近程度，实现对智能手机成像质量颜色的优劣排序。对真实场景采集的图片进行实验，并与现有的两种决策方法进行对比验证。结果表明，所提方法能提高评价效率、节省人力，并可以获得与人眼主观判断一致性较好的评价结果。

Halide perovskite light-emitting electrochemical cells are a novel type of the perovskite optoelectronic devices that differs from the perovskite light-emitting diodes by a simple monolayered architecture. Here, we develop a perovskite electrochemical cell both for light emission and detection, where the active layer consists of a composite material made of halide perovskite microcrystals, polymer support matrix, and added mobile ions. The perovskite electrochemical cell of CsPbBr₃:PEO:LiTFSI composition, emitting light at the wavelength of 523 nm, yields the luminance more than 7000 cd/m² and electroluminescence efficiency of 1.3×10⁵ lm/W. The device fabricated on a silicon substrate with transparent single-walled carbon nanotube film as a top contact exhibits 40% lower Joule heating compared to the perovskite optoelectronic devices fabricated on conventional ITO/glass substrates. Moreover, the device operates as a photodetector with a sensitivity up to 0.75 A/W, specific detectivity of 8.56×10¹¹ Jones, and linear dynamic range of 48 dB. The technological potential of such a device is proven by demonstration of 24-pixel indicator display as well as by successful device miniaturization by creation of electroluminescent images with the smallest features less than 50 μm.

姿态指示器指示飞行姿态角信息。提出一种基于三维图形学的三维虚拟姿态指示器实现方法，将姿态指示器的主体部分设计为姿态球结构；通过纹理映射技术绘制相应的刻度信息；使用Blinn⁃Phong光照模型增强姿态球的立体感。人机工效评价实验表明，三维虚拟姿态指示器人机工效指标评分较好，其中立体性评分为3.95，显著高于对照组得分。在ROC⁃RK3399⁃PC主板上进行三维虚拟姿态指示器的移植与验证，实现硬件平台国产化。研究证实，三维虚拟姿态指示器符合人机工效、通用性强，能够稳定运行于国产硬件平台。
