Claim 15:
16. A system for aligning exposure center points of multiple cameras in a VR system, configured to implement the method for aligning exposure center points of multiple cameras in a VR system as claimed in claim 1, comprising:
a type frame division module, the multiple cameras, a first type frame processing module and a second type frame processing module, wherein the type frame division module is configured to instruct the multiple cameras to successively obtain a first type frame and a second type frame;
the multiple cameras are configured to successively acquire image data of the first type frame and the second type frame according to the instruction of the type frame division module, and acquire image data according to a preset frame rate;
the first type frame processing module is configured to adjust VTS data of the first type frame so that the VTS data changes with the change of the exposure parameters so as to fix a time interval between an exposure center point of the first type frame and an FSIN synchronization signal in a VR system; and
the second type frame processing module is configured to adjust VTS data of the second type frame according to the VTS data of the first type frame, and fix a time interval between an exposure center point of the second type frame and the FSIN synchronization signal so as to complete the alignment of exposure center points of the cameras,
wherein VTS data of the second type frame is adjusted according to the VTS data of the first type frame comprises: taking a sum of the value of the VTS data of the second type frame and the value of the VTS data of the first type frame always as a same value in the whole acquiring process such that the image data of the first type frame and the second type frame can be stably output at a specific frame rate.
