An assistance method is provided. The method is used to guide a blind to working and doing something. The method includes: obtaining image captured by at least one camera, the image includes distance information indicating a distance between the at least one camera and objects captured by the at least one camera detecting whether there is object(s) in the image establish a 3D model according to the image and the distance information when there is object(s) in the image determine whether the object is the predetermined object or the bar and further prompt the user that the distance between the predetermined object or the bar and the user through an audio output device.一種行走輔助方法,該行走輔助方法用於輔助一使用者的行走,該行走輔助方法包括:獲取一攝像裝置攝取的場景圖像,該場景圖像中包括物品各點與攝像裝置之間的距離資訊;偵測該場景圖像中是否存在物體;當偵測該場景圖像中存在物體時,根據該獲取的場景圖像及該物品各點到攝像裝置之間的距離建立該場景的三維模型;藉由該場景的三維模型來確定該物體為特定物體還是障礙物;藉由一聲音輸出裝置提示使用者前方的特定物體和障礙物與該使用者之間的距離。1‧‧‧行走輔助裝置10‧‧‧行走輔助系統11‧‧‧範本建立模組12‧‧‧影像獲取模組13‧‧‧影像分析模組14‧‧‧模型建立模組15‧‧‧偵測模組16‧‧‧執行模組20‧‧‧中央處理器30‧‧‧記憶體2‧‧‧攝像裝置3‧‧‧聲音輸出裝置
