Slow traffic assessment method based on panoramic image

Abstract

The invention discloses a slow traffic evaluation method based on a panoramic image. The slow traffic evaluation method comprises the following steps: acquiring slow traffic panoramic image data by using a panoramic camera; preprocessing the slow traffic panoramic image trajectory data; achieving target detection and image segmentation of the slow traffic panoramic image through a deep learning algorithm; acquiring various targets in a slow traffic panoramic image, and acquiring data such as types, positions, lengths, areas, numbers, accuracy and the like of slow traffic facilities; respectively calculating convenient, safe and comfortable indexes for bicycles and pedestrians; calculating comprehensive indexes in a weighted mode for the bicycles and the pedestrians; and performing weighted calculation on a slow traffic comprehensive index, performing optimization adjustment on design, construction and reconstruction of urban slow traffic facilities, and improving urban traffic. According to the invention, technical reference basis is provided for urban management departments, urban traffic planning and facility construction, a high-quality slow traffic travel environment is provided for the public, and urban resident travel ecologicalization and sustainable development of an urban traffic system are further promoted.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic systems, in particular to a panoramic image-based slow traffic evaluation method. Background technique [0002] Walking and cycling are the most common modes of travel in most small and medium-sized cities. The concept of slow traffic was introduced into China in the early 21st century. Although some small and medium-sized cities have formulated slow-moving traffic plans, so far slow-moving people are still in the stage of lacking basic safety guarantees. Slow travel in small and medium-sized cities still faces the problems of a large travel base, many problems, and inadequate planning. As the problems brought about by motorized transportation become more and more serious, Shanghai, Wuhan, Hangzhou and other cities have successively carried out the planning of slow-moving traffic systems, which has also promoted the theoretical research of slow-moving traffic systems. Since the resea...
