Disclosed are a single-camera ranging method and system. When a mobile terminal is in a camera photographing mode, the outer edge of a target object is continuously recognized and tracked. A user translates the mobile terminal toward the target object, and the mobile terminal calculates the distance between the mobile terminal and the target object according to the change in the display width of the target object on a screen or the change in the view-finding width on a mobile terminal screen and the translation distance of the mobile terminal. The whole ranging process is completed based on the existing mobile terminal image preprocessing and movement perception functions, thereby being able to achieve single-camera ranging based on the mobile terminal under the condition of not adding any optics. Adding an attitude monitoring step during the mobile terminal translation can further ensure the accuracy of ranging. |
