A method for aligning exposure center points of multiple cameras in a VR system comprising: acquiring, by the multiple cameras working synchronously, image data of a first type frames according to a preset frame rate, the first type frames being used to track external objects, and exposure parameters of the multiple cameras during tracking being dynamically changed according to changes in the external objects; adjusting Vertical Timing Size VTS data of the first type frames from a default VTS value, the VTS data being changed according to the dynamic change of the exposure parameters, to fix the time interval between exposure center points of the first type frames and a Frame Synchronization Input FSIN synchronization signal in the VR system; acquiring, by the multiple cameras working synchronously, image data of a second type frames according to the preset frame rate, the second type frames being used to track an optical handle, and exposure parameters of the multiple cameras during tracking are consistent; wherein the image data of the first type frames and the image data of the second type frames are acquired sequentially and alternately during an entire acquisition process; adjusting VTS data of the second type frames according to the VTS data of the first type frames, and fixing the time interval between exposure center points of the second type frames and the FSIN synchronization signal, to complete the alignment of exposure center points of the multiple cameras, wherein the adjusting VTS data of images of the second type frames according to the VTS data of the first type frames comprises causing a sum of the value of the VTS data of the second type frames and the value of the VTS data of the first type frames to be a same fixed value during the entire acquisition process. acquiring, by the multiple cameras working synchronously, image data of a first type frames according to a preset frame rate, the first type frames being used to track external objects, and exposure parameters of the multiple cameras during tracking being dynamically changed according to changes in the external objects; adjusting Vertical Timing Size VTS data of the first type frames from a default VTS value, the VTS data being changed according to the dynamic change of the exposure parameters, to fix the time interval between exposure center points of the first type frames and a Frame Synchronization Input FSIN synchronization signal in the VR system; acquiring, by the multiple cameras working synchronously, image data of a second type frames according to the preset frame rate, the second type frames being used to track an optical handle, and exposure parameters of the multiple cameras during tracking are consistent; wherein the image data of the first type frames and the image data of the second type frames are acquired sequentially and alternately during an entire acquisition process; adjusting VTS data of the second type frames according to the VTS data of the first type frames, and fixing the time interval between exposure center points of the second type frames and the FSIN synchronization signal, to complete the alignment of exposure center points of the multiple cameras, wherein the adjusting VTS data of images of the second type frames according to the VTS data of the first type frames comprises causing a sum of the value of the VTS data of the second type frames and the value of the VTS data of the first type frames to be a same fixed value during the entire acquisition process.
