Embodiment Construction

[0022] The intelligent eye movement tracking method of the present invention will be further described in detail below in conjunction with specific embodiments. Also, in the following description, when a detailed description of known functions and designs employed may obscure the subject matter of the present invention, these descriptions will be omitted here.

[0023] The accompanying drawing is a flow chart of the eye movement test analysis method of the present invention. In the figure, the steps include:

[0024] 1), select the test item and test method, and generate a sampling task list;

[0025] 2), the micro-processing system sets the LED visual stimulation mode and LED indication position according to the tasks in the task list;

[0026] 3), start video sampling;

[0027] 4) Real-time analysis of video images, output and analysis of raw data;

[0028] 5), judge whether the task sequence is completed, if not, return to step 3; if completed, stop video sampling;

Abstract

The invention discloses a method of and analyzing the eye moving test, which comprises the procedures as follows: selecting test items and method to generate the task list; confirming LED vision stimulating mode and indicating position; vision sampling; analyzing the vision image in real time and outputting original data; judging whether the task sequence is finished, if not yet, returning to position again, while, if finished, stopping the vision sampling; reprocessing and analyzing as well as expressing the data in image shape to form an individual report forms, then stopping the test. The invention can test and analyze automatically the moving of eyeball and output and analyze the original data and the report form in image shape and then provide it to medical staffs for them to analyze and judge the disease on eye. The invention test for the moving of the eye controlled by the micro-processing system automatically, which reduces the working labor for medical staffs.

Description

technical field [0001] The invention relates to the related technical field of medical instruments, in particular, to an eye movement test analysis method used in an eye movement test analyzer. Background technique [0002] In 1975, an eye tracker with a magnetoelectric induction loop as the method of picking up eye movement signals appeared. On the one hand, due to the influence of the physical characteristics of the eyeball movement, the signal is already a signal of an abnormal state; [0003] The infrared reflective eye tracker appeared around 1980, which fundamentally solved the problem of interference with the physical characteristics of eye movements. However, infrared light irradiation cannot be used for long-term detection, and there are also eye movements caused by the influence of light signals. Possibility of changing characteristics. [0004] There is also a design scheme that uses corneal patches to reflect infrared light. The main purpose is to reduce the co...
