specific Embodiment approach 2

[0043]Embodiment 2. The difference between this embodiment and the binocular image separation detection device described in Embodiment 1 is that the computer 1 includes a detection module implemented by software, and the detection module includes:

[0044] A patient information input module for patient information input;

[0045] A position adjustment module for controlling the movement of the screen 4 on the screen slideway 3;

[0046] A detection template selection module for selecting a detection template;

[0047] A detection template correction module for correcting the selected detection template according to errors generated by human vision;

[0048] A detection start reminder module that is used to issue a start detection instruction to the detection personnel after the detection template calibration is completed;

[0049] A coordinate detection module for real-time detection of the track coordinates produced by the trackball 6;

[0050] The click detection module f...

specific Embodiment approach 3

[0059] Embodiment 3. The difference between this embodiment and the binocular image separation detection device described in Embodiment 2 is that the process of selecting a detection template is as follows:

[0060] Set the horizontal rotation angle of the eyeball to α, the vertical rotation angle of the eyeball to β, and select the intersection point of the line segment where α and β are equal to ±20° as the detection template;

[0061] According to the first eye position, the second eye position and the third eye position, nine standard points are selected, the detection distance and the detection angle are set, and the relative positions of the nine standard points on the screen 4 are obtained.

Abstract

A binocular video separation detection device and method, relating to the field of video separation detection. The problems existing in the existing binocular image separation detection technology are solved. The device includes a computer, a projector, a screen, a screen slideway, a trackball and a test bench, the image signal output end of the computer is connected with the image signal input end of the projector, the projector projects images to the screen, and the test bench is fixed on the front of the screen. In the front, the screen changes the distance between the screen and the test platform through the screen slideway. A head fixing device is fixed on the test platform to fix the patient's head. The track signal output end of the track ball is connected to the track signal input end of the computer. The trackball generates track points on the screen. The detection method can realize the automation and integration of the whole process of detection from detection mode setting, detection program operation, detection result image information collection, atlas generation, result quantification to analysis and interpretation, and can truly reflect the difference between the real image and the virtual image in the patient's visual separation. location relationship.

Description

technical field [0001] The invention relates to the field of video separation detection. Background technique [0002] Separation of binocular vision refers to the production of two images when two eyes see an object, which is often called double vision, and it is also called diplopia clinically. Due to the loss or weakening of the extraocular muscles, when the two eyes look at the target, the line of sight of one eye deviates from the target, so that the image of the object cannot fall on the corresponding point of the macular area of ​​the two eyes at the same time, so that people regard one object as two . This symptom is mostly due to cerebrovascular disease, diabetes, trauma, aneurysm, infection and other reasons that damage the eye motor nerve and cause ophthalmoplegia, which is a secondary symptom. Patients often cannot distinguish the real image and the virtual image in the double image, which brings inconvenience to the life, study and work of the patient. [000...
