Target object extraction method, device and system and computer readable storage medium

The invention provides a target object extraction method, device and system and a computer readable storage medium, and belongs to the technical field of computers, wherein the terminal can display apreset interface comprising candidate object categories and candidate feature extraction options, then, the selection operation of the user on the candidate object category and the candidate feature extraction option can be detected. The method comprises the following steps: firstly selecting a candidate object type and a selected candidate feature extraction option, then generating feature configuration information of a target object according to the selected candidate object type and the selected candidate feature extraction option, and finally, sending the feature configuration informationto a server, and extracting a matched object by the server according to the feature configuration information. Therefore, when an object conforming to a certain feature needs to be extracted; a user only needs to select the ty
