L'invention concerne un procédé et un dispositif d'acquisition d'informations de navigation, ainsi qu'un terminal mobile. Le procédé consiste : à acquérir continuellement, par un terminal mobile, une distance d'avancée et une direction d'avancée correspondant à chaque section de route sur une pluralité de sections de route qui sont reliées en séquence, les directions d'avancée sur chaque deux sections de route adjacentes étant différentes (S102) ; sur la base des distances d'avancée et des directions d'avancée acquises, à compter, par le terminal mobile, des informations de navigation concernant des routes d'avancée sur la pluralité de sections de route (S104). Selon le procédé, dans le cas où une ressource externe n'est pas utilisée, les routes d'avancée peuvent être enregistrées uniquement par un matériel intégré du terminal mobile, et les routes d'avancée enregistrées peuvent également être affichées ou traitées, en améliorant ainsi l'expérience d'utilisateur du terminal mobile.
