| 摘 要： | 研究了一种利用二维图像识别三维物体的方法。通过颜色特征提取物体的有效区域．使用链码描述了区域中三维物体的形状特征，并形成物体的形状特征向量。将该特征向量作为所设计的BP神经网络的输入进行物体匹配识别，网络输出为属于某种物体的隶属度。通过在各种光照环境下不同三维物体的二维彩色图像进行实验，证明了所提出方法的有效性。 |
| 关 键 词： | 三维物体识别 颜色特征 形状特征 链码 BP神经网络 |

| Abstract: | Summarizing an approach basing on 2-D image to recognize 3-D objects. Extracting the object's valid area by way of complying with color characteristics,using a chain code to describe the shape characteristics of 3-D objects in the area,and the object's shape characteristic vector is formed.The vector characteristic is used for object-matching recognizing of what is designed for input of BP neural network.The network output is a kind of subordination of certain objects.Effectiveness of the method is proved through an experiment of 2-D color images of different 3-D objects in an environment under various luminous conditions. |
| Keywords: | D object recognition color characteristic shape characteristic chain code BP neural network |
