| titleOfInvention | Method for calculating fundus oculi target motion amount of line scan imaging system |
| abstract | Disclosed is a method for calculating the fundus oculi target motion amount of a line scan imaging system, comprising: A. using a line scan fundus oculi camera to obtain a fundus oculi image, and dividing, according to chronological order, each frame image of a reference frame and a target frame into a plurality of equally spaced sub-frame elements according to data reached by the scanning camera; B. using a calculation processing unit to receive the latest sub-frame metadata, and starting a preset algorithm to calculate the position of the current sub-frame element relative to said reference frame, or locate the relative positions of the sub-frame element of the target frame and the sub-frame element of the reference frame; C. using frequency multiplication technology, setting a scan signal and a frame synchronization signal to synchronously trigger the line scan camera to obtain the sub-frame image synchronized with the scan signal; according to the sequence of arrival of each sub-frame element to a host system, calculating in real time the fundus oculi movement information contained in each sub-frame element. Using the present invention, it is possible to effectively improve the instantaneity and precision of target tracking, thereby further improving imaging efficiency. |
