It can be presented by visual interface, these video files can pass through for the original image in step 101, electronic equipment 10
Projecting cell projects it, and specific projection theory and process please refer to the prior art.
In step 102, electronic equipment can indicate that image is adopted prior to, concurrently with, or after projecting to original image
Collect unit and acquires image, acquisition perspective plane of the direction towards projecting cell of image acquisition units, so that projecting cell is thrown
When shadow, image acquisition units can get the picture frame comprising projection image.It is adopted wherein it is possible to manually adjust image for user
Collect the Image Acquisition direction of unit, or the acquisition direction of image acquisition units adjust automatically image acquisition units.
In step 103, after electronic equipment obtains at least two field pictures of image acquisition units acquisition, according to image recognition
Technology determines that feature object, feature object therein can be the object with character shape in each frame image, can also
Think with the object of signature identification (or label), there can also be the object of preset spatial relation, such as and perspective plane
Distance be less than given threshold object, etc..
In step 104, electronic equipment by according to preset algorithm based on feature object at least two picture frames each frame
In spatial positional information, on the projection surface determine a corresponding tracing point.Specifically, the spatial positional information of feature object
It can be characterized the directional information of object, any on feature object direction perspective plane can be determined according to directional information, i.e.,

It is characterized label.
Specifically, electronic equipment after determining the characteristic locus on perspective plane, according to image recognition technology, is determined
The relative positional relationship of the projection image of characteristic locus and original image, and the everywhere position in projection image can be mapped to
A pixel in original image, therefore can determine pixel collection on the original image according to characteristic locus, as
Characteristic image position.Then, the pixel value of the pixel of electronic equipment modification characteristic image position, forms signature pixel,
And generate new drawing image.When being projected by projecting cell to drawing image, the corresponding projection in characteristic image position
It is characterized label.
In the technical solution that mode 1 provides, by operating characteristics object, feature mark can be not only shown on the projection surface
Note can also realize the mark to original image itself and editor, fastly by the information preservation of signature in original image
Victory is convenient.
Mode 2, electronic equipment make projecting cell project to form perspective plane according to corresponding first projection mode of original image
On region in addition to characteristic locus；And project projecting cell according to second projection mode different from the first projection mode
Characteristic locus is formed, so as to show signature at characteristic locus.
Specifically, electronic equipment indicates that projecting cell uses for the region except projected footprint in original projection image
Front projection forms identical first projection mode of original projection image and is projected therewith, and for the projected footprint on perspective plane
Corresponding region, electronic equipment instruction projecting cell are projected using the second projection mode, and the first projection mode is thrown with second
The difference of shadow mode can be with are as follows: the color of the different perhaps throw lights of the brightness of the light projected when projection is different or in spy
Track is levied in projection image, the second projection mode is not throw light, to form dark space image.
The mode for changing throw light by instruction projecting cell, forms signature, and operand is small, implementation letter
It is single.

Preset algorithm in, each position (can be determined whether outside perspective plane by depth of view information) in picture frame outside perspective plane is right
Should at one in perspective plane position, therefore, electronic equipment can be corresponding by the feature object outside perspective plane according to preset algorithm
A tracing point in perspective plane, as previously mentioned, the tracing point can be in the projection image of original image, it can also be in original graph
Except the projection image of picture.
When obtaining a tracing point according to each picture frame, tracing point, which is connected, can form characteristic locus.It is practical
It in, can be connected between the corresponding tracing point of adjacent image frame with straight line, can also be connected by round and smooth curve.For example,
If the time interval of adjacent two frame of Image Acquisition is shorter, adjacent track point is closer, and can be connected by straight line
It connects.And if the time interval of adjacent two frame of Image Acquisition is longer, the distance of adjacent track point farther out, by curve by track
Point is connected, and the characteristic locus obtained that can be connected is more naturally, beautiful.
Optionally, in the embodiment of the present invention, the spatial positional information of feature object include feature object directional information and/
Or location information.Further, spatial positional information can also include the depth of view information of feature object.Such as in conjunction with depth of view information with
