A method for detecting distance in a smart portable device includes acquiring an image of a target object, calculating a length of a side of the target object in the image, acquiring a predicted length of the side of the target object, and determining a distance between the smart portable device and

대표청구항 ▼

1. A method for detecting distance in a smart portable device comprising: receiving a first digital image comprising the target object by a photo sensor of an image acquisition unit of the smart portable device;displaying and enlarging the first display image by a display unit of the image acquisition unit;selecting a digital image of the target object in the first digital image by a selection unit of the image acquisition unit;automatically calculating a length of a side of the target object in the digital image displayed on a display unit by a processing means of the smart portable device;acquiring a predicted length of the side of the target object from user prediction by the processing means;automatically determining a mil value of the length of the side in the digital image from the length of the side in the digital image by the processing means without user assistance; andcalculating the distance between the smart portable device and the target object according to a ratio of the predicted length to the mil value by the processing means. 2. The method of claim 1 further comprising: determining an angle when acquiring the digital image of the target object; andcorrecting the distance between the smart portable device and the target object according to the angle. 3. A device for detecting distance in a smart portable device comprising: an image acquisition unit, for acquiring a digital image of a target object by a photo sensor, the image acquisition unit comprising: an image reception unit, for receiving a first digital image comprising the target object;a display unit, for displaying and enlarging the first digital image; anda selection unit, for selecting the digital image of the target object in the first digital image according to a user command;a processing device, for receiving instructions to execute the following steps: automatically calculating a length of a side of the target object in the digital image displayed on the display unit;acquiring a predicted length of the side of the target object from user prediction;automatically determining a mil value of the length of the side in the digital image from the length of the side in the digital image without user assistance; andcalculating the distance between the smart portable device and the target object according to a ratio of the predicted length to the mil value. 4. The device of claim 3, wherein the processing device further receives instructions to execute: determining an angle when the image acquisition unit acquires the digital image of the target object; andcorrecting the distance between the smart portable device and the target object according to the angle.
