To provide a traffic sign detection method in which a detection error in a traffic sign can be reduced to ensure accuracy of a decision result of a vehicle in order to solve a problem that a detection error in a traffic sign is significant, whereby safety of vehicle driving is improved.SOLUTION: A traffic sign detection method includes a step of determining a traffic sign image frame sequence collected by an on-vehicle camera and odometer frame information corresponding to each frame image in the image frame sequence, a step of determining a residual function and an optimization model based on each frame image and the odometer frame information corresponding to each frame image, a step of determining a target position of the traffic sign in a preset coordinate system based on the residual function and the optimization model, and a step of determining a target position attitude of the traffic sign and a real-time distance between the on-vehicle camera and the traffic sign based on the target position.SELECTED DRAWING: Figure 2

    【課題】交通標識の検出誤差が大きいという課題を解決するために、交通標識の検出誤差を小さくし、車両意思決定結果の正確度を確保することができ、それにより車両走行の安全性を向上させる交通標識の検出方法を提供する。【解決手段】交通標識の検出方法は、車両の車載カメラにより収集された交通標識の画像フレームシーケンス、及び画像フレームシーケンスにおける各フレーム画像に対応するオドメーターフレーム情報を決定するステップと、各フレーム画像及び各フレーム画像に対応するオドメーターフレーム情報に基づいて、残差関数及び最適化モデルを決定するステップと、残差関数及び最適化モデルに基づいて、予め設定された座標系における交通標識の目標位置を決定するステップと、目標位置に基づいて、交通標識の目標位置姿勢又は車載カメラと交通標識との間のリアルタイム距離を決定するステップと、を含む。【選択図】図2
