Method for recognizing picture, method and apparatus for labelling picture, and storage medium

A method for labelling a picture, comprising:

• acquiring a target object picture;
• acquiring, based on a pre-established target object classification model, information of a region of a target object from the target object picture;
• and
• labelling a positioning key point for the target object picture based on a pre-established target object key point positioning model, wherein the pre-established target object key point positioning model defines a positioning region enclosing a segment of the target object, the positioning region having a predetermined shape and a predetermined size, and defines a point located in the positioning region as the positioning key point corresponding to the positioning region, the positioning key point and the positioning region having a predefined position relationship.

An apparatus for recognizing a picture, comprising:

• a target object picture acquiring module, configured to acquire a target object picture labelled with a positioning key point and a region of the target object, wherein a positioning region enclosing a segment of the target object is defined, the positioning region having a predetermined shape and a predetermined size, and a point located in the positioning region is defined as the positioning key point corresponding to the positioning region, the positioning key point and the positioning region having a predefined position relationship;
• a target object region picture extracting module, configured to determine a location of the positioning key point in the target object picture;
• determine a region having the predetermined shape, the predetermined size, and the predefined position relationship with the positioning key point in the target object picture, as the positioning region corresponding to the labelled positioning key point based on location of the labelled positioning key point and extract the positioning region in the target object picture;
• and
• a target object feature information acquiring module, configured to acquire feature information representing the positioning region based on a region feature recognition model corresponding to the segment enclosed by the positioning region.

An apparatus for labelling a picture, comprising:

• a target object picture acquiring module, configured to acquire a target object picture;
• a region of the target object acquiring module, configured to acquire information, in the target object picture, of a region of the target object based on a pre-established target object classification model;
• and
• a target object key point labelling module, configured to label a positioning key point for the target object picture based on a pre-established target object key point positioning model, wherein the pre-established target object key point positioning model defines a positioning region enclosing a segment of the target object, the positioning region having a predetermined shape and a predetermined size, and defines a point located in the positioning region as the positioning key point corresponding to the positioning region, the positioning key point and the positioning region having a predefined position relationship.

A non-volatile computer storage medium, storing one or more modules, wherein when the one or more modules are performed by a device for executing a method for recognizing a picture, the device is caused to:

• define a positioning region enclosing a segment of a target object, the positioning region having a predetermined shape and a predetermined size;
• define a point located in the positioning region as a positioning key point corresponding to the positioning region, the positioning key point and the positioning region having a predefined position relationship;
• acquire a target object picture labelled with a positioning key point and a region of the target object;
• determining a location of the positioning key point in the target object picture;
• determining a region having the predetermined shape, the predetermined size, and the predefined position relationship with the positioning key point in the target object picture, as the positioning region corresponding to the labelled positioning key point based on location of the labelled positioning key point;
• extracting the positioning region in the target object picture;
• and
• acquire feature information representing the positioning region based on a region feature recognition model corresponding to the segment enclosed by the positioning region.
