Step 201, takes pictures to object, draws photo.
Photo in the present embodiment is entity photo, i.e. in esse photo, certainly, also after taking pictures to object, can not draw entity photo, but must generating pictures data, i.e. generating virtual photo, for for needing the object of measurement size to focus.
Step 202, selects a focus according to object.
When unique for the focus needing the object of measurement size automatically to generate, this focus is directly selected to focus; When not unique for the focus needing the object of measurement size automatically to generate, user needs to select a focus to focus in the focus automatically generated at these.
Step 203, measures the distance between object in focus and photo.
Be understandable that, because the equipment for taking pictures is in user's hand, therefore, the distance in focus and photo between object is the distance between user and object.
Step 204, generates the Pixel Dimensions of object.
Step 2041, identifies the border of object, draws the Boundary Recognition result of object.
Step 2042, calculates the Pixel Dimensions of object according to recognition result.
That is, first the border of object is identified, namely obtain the profile of this object, then calculate the Pixel Dimensions of object according to the profile of this object.
Step 205, generates the physical size with reference to image.
Wherein, be generally circle, the rule such as square, symmetrical figure with reference to image, to calculate the physical size with reference to image, certainly, the shape with reference to image is not limited thereto, and can also be other shapes, not repeat them here.
Step 206, generates the minimum pixel size with reference to image.
