Object detection based on color and shape features for service robot in semi-structured indoor environment

摘要

Intelligent service robot is a challenging area of research that is rapidly expanding in our daily life. To meet robot’s object detection requirements in a messy surrounding, this paper provides a visual object detection method based on color and shape features. Firstly, a color hierarchical model and a multi-size filter are built to obtain initial object regions from scene image. Then a straight line-corner-arc strategy is presented to detect shape features. After comparing color and shape features with known-objects’ features stored in database, the detection scope is narrowed. So speeded up robust features algorithm is used to quickly match object features. The proposed method is tested by mobile robot in a semi-structured indoor environment. Finally, combined with the above steps, the total detection accuracy achieves 88.5% that confirms the feasibility of the proposed method.
