# Evaluation Model of Parking Equipment Planning and Design Based on Object-Oriented Technology
## 5 Conclusions  
1. Multi-scale segmentation and image extraction of satellite images in the study area are carried out through object-oriented technology, combined with the characteristics of the image and feature types in the study area, so that the similar surface information in the image can be classified and merged;
2. Based on the results of classification and extraction of feature information in the study area, the edge of the image contour is regularized to obtain a planar map of the area. This information graph is the basis of this article's parking equipment planning and design evaluation model;
3. From the perspective of science, the influencing factors of parking space layout are divided into two aspects: rationality and suitability, and an evaluation model for parking equipment planning and design is proposed. The rationality is to carry out the research from the physical and objective aspects, comprehensively consider the environmental conditions in the research area, and plan the layout of the maximum capacity of parking spaces in the research area. The suitability is based on the study of parking demand. On the basis of the maximum capacity layout planning of parking spaces, the accessibility parking space planning and the layout design of multi-storey parking equipment are carried out.
4. The feasibility of the evaluation model for the planning and design of parking equipment is verified by an actual case. Based on the acceptable pick-up distance and time, and considering the surface information of parking area and the rationality and suitability of parking layout, the specific planning and design is carried out including of the type, quantity and location of parking equipment.
5. The object image technology is used in the map extraction of the evaluation model of parking equipment planning and design proposed in this paper. This technology has fast recognition speed and low cost. It is a valuable planning map extraction method, which can provide a powerful reference for parking planning and design. However, due to the influence of sampling image accuracy and classification objects, the accuracy of object-oriented technology still needs to be further improved.
