Method of controlling virtual content, terminal device and computer readable medium

A method of controlling virtual content, comprising:

• acquiring a target image including a marker, wherein a plurality of sub-markers are distributed on the marker, features of the plurality of sub-markers are different, and there is a preset correspondence between the features and identifications of the sub-markers, each of the plurality of sub-markers comprises at least one feature point, the feature comprises information of the at least one feature point of the sub-marker;
• determining a blocked target, wherein the blocked target is a blocked sub-marker of the plurality of sub-markers in the target image;
• acquiring, as a reference, at least one blocked sub-marker determined within a preset period before a target time point, wherein the target time point is a time point at which the blocked target is determined to be blocked,
• determining blocking change information according to the reference and the blocked target, the blocking change information comprises target change information indicating a change trend from the reference to the blocked target,
• generating a control instruction for the virtual object according to the blocking change information;
• determining a change duration indicating a duration between a time point at which the reference is determined to be blocked and the target time point,
• generating a sub-control instruction for the virtual object according to the change duration;
• and
• controlling a displayed virtual object based on the control instruction and the sub-control instruction.

A non-transitory computer readable medium storing one or more programs configured to be executed by one or more processors of a terminal device, the one or more programs comprising instructions for:

• adjusting an imaging parameter of the marker;
• acquiring a target image including a marker according to the adjusted imaging parameter, wherein a plurality of sub-markers are distributed on the marker, features of the plurality of sub-markers are different, each of the plurality of sub-markers comprises at least one feature point, the feature comprises information of the at least one feature point of the sub-marker;
• determining a blocked target, wherein the blocked target is a blocked sub-marker of the plurality of sub-markers in the target image;
• acquiring, as a reference, at least one blocked sub-marker determined within a preset period before a target time point, wherein the target time point is a time point at which the blocked target is determined to be blocked,
• determining blocking change information according to the reference and the blocked target, the blocking change information comprises target change information indicating a change trend from the reference to the blocked target,
• generating a control instruction for the virtual object according to the blocking change information;
• generating a sub-control instruction for the virtual object according to blocked information of the blocked target;
• and
• controlling the displayed virtual object based on the control instruction and the sub-control instruction.
