项目摘要

For the purpose of development of the assistant robot for handicapped and aged persons, we have developed some recognition methods for objects in artificial and natural lightings.[1] Recognition of environmental lighting :(1) Color compensation : We have developed a method for the detection of the changing property of the environmental lighting by using neural networks, and shown that this method could be applied to the compensation of real scene images changed by artificial and natural lightings.(2) Segmentation and compression for real scene images : By using multiple neural networks with the cooperative function, we have developed segmentation and compression methods for real scene images changed by artificial and natural lightings. Also we have shown that their methods could detect the changing property of the environmental lighting.[2] Object recognition based on the shape analysis :(1) Recognition of circular objects : We have made some algebraic formulas for representing the geometrical properties of ellipses that they have diameters and conjugate diameters, and shown that circular objects could be recognized accurately in short processing time by using the formulas.(2) Contour segmentation : Because most of contours obtained from real images become links of edges of different objects, we have proposed a method to segment the contours into individual object sections by estimating the curvatures of neighboring contours.[3] Cooperative recognition of environments and objects : We have proposed a scene predicting CG-system for supporting the cooperative recognition of environmental lighting and objects, and shown experimentally that the system is very effective to recognize objects and environmental lightings in real scene. The system drastically cuts the processing cost of recognizing objects in closed space influenced by time-variant lighting.
为了开发残疾人和老年人辅助机器人,我们开发了一些人工照明和自然照明下物体的识别方法环境照明识别:(1)色彩补偿:本文提出了一种基于神经网络的环境照明变化特性检测方法,并证明该方法可以应用于人工照明和自然照明对真实场景图像变化的补偿。(2)真实场景图像的分割与压缩:利用具有协同函数的多个神经网络,开发了人工光照和自然光照变化的真实场景图像的分割与压缩方法。我们还证明了他们的方法可以检测环境照明的变化特性基于形状分析的物体识别:(1)圆形物体的识别:给出了椭圆具有直径和共轭直径的几何性质的代数公式,并证明了利用这些公式可以在较短的处理时间内准确识别出圆形物体。(2)轮廓分割:由于从真实图像中获得的轮廓大部分是不同物体边缘的链接,我们提出了一种通过估计相邻轮廓的曲率将轮廓分割成单个物体截面的方法环境与物体的协同识别:提出了一种支持环境照明与物体协同识别的场景预测cg系统,并通过实验证明该系统对真实场景中物体与环境照明的识别是非常有效的。该系统极大地降低了在受时变光照影响的封闭空间中识别物体的处理成本。
