基於幾何關係的側面單張腳踏車影像偵測演算法

[[alternative]]Bicycle Detection on Single Side-view Image Based on the Geometric Relationship

Description

[[abstract]]交通運輸系統安全性的增進得到相當多關注。為了達成這個目標,研究者們發展了於交通道路偵測與分析車輛或行人的方法,但是腳踏車也是道路安全的一個顯著因子,相關研究卻相對較不完備。腳踏車影像是由兩個橢圓形式輪子與兩個三角形形式車架所組成,本論文基於上述觀察,提出一個側面腳踏車影像偵測演算法。經由提出的側面腳踏車影像偵測演算法、腳踏車數學模型、三角形與橢圓形之間的幾何關係條件,根據示範實作與資料量的評估結果得知,計算是快速的。此外,我們提出的演算法不須訓練過程,而且只須單張影像作為輸入資料。實驗結果亦顯示本文提出的腳踏車模型與偵測演算法的可行性與性能。

[[abstract]]Improving the safety of transportation systems attract lots of attention Researchers introduced their methods to detect and analyze the vehicle and the pedestrian on the road to accomplish this goal However the bicycle is also a significant factor of the safety on a road but has not been well-studied relatively In this dissertation a bicycle detector for side-view image is proposed based on the observation that a bicycle consists of two wheels in the form of ellipse shapes and a frame in the form of two triangles Through the proposed triangle detection algorithm the bicycle model and the geometric constraints on the relationship between the triangles and ellipses the computation is fast according to the sample implementation and the evaluation of the reduced data amount Besides the training process is unnecessary and only single image is required for our algorithm The experimental results are also given in this paper to show the practicability and the performance of the proposed bicycle model and bicycle detection algorithm
