Problems solved by technology

[0007] (1) Measurement content and accuracy are limited: hand-held pupil penlights, flashlights, etc. cannot objectively, quantitatively and accurately measure the pupil size and light reflection, including the inability to measure the light reflection latency and pupil contraction speed, etc. ;
[0008] (2) Poor portability: the pupil detector is bulky and heavy, and needs to be placed in a flat environment, so it is not suitable for use in the field;
[0009] (3) The detection object is limited: the existing equipment, the stimulation time of the stimulating light source is fixed, and the disease cannot be checked for special patients, such as patients with severe coma;
[0010] (4) Inconvenient operation and susceptible to interference from subjective factors: Traditional pupil detector equipment requires manual participation in many test procedures. The differences in manual operations and subjective judgments may lead to inaccurate tests and require the cooperation of the subjects Very high, it will bring discomfort to the subject;
[0011] (5) Poor real-time performance: The camera acquisition frame rate of the existing pupil detection equipment is low, and the real-time performance of the pupil measurement software is poor, so the measurement accuracy is limited;
[0012] (6) Limited operating efficiency: Existing portable devices do not support binocular pupillary light reflex inspection, and cannot screen patients with abnormal indirect light reflex;
[0013] (7) The measurement result is not intuitive: the existing pupil light reflex equipment provides the measurement result parameters, and there is no intuitive change curve

Description

technical field [0001] The invention belongs to the field of visual detection, and specifically relates to a binocular pupil light reflection tracking system, which includes an infrared camera, an infrared lighting source, a stimulating light source, a grasping device, a measurement display device, a single-chip microcomputer control, a data processing control module and a pupil The tracking measurement system module is suitable for medical applications in clinical ophthalmology, neurosurgery, psychiatry and related fields. Background technique [0002] When the human eye is stimulated by light, the pupil narrows, which is called the pupillary light reflex. The constriction of the pupil is accomplished by the pupillary sphincter muscle innervated by the parasympathetic nerve in the oculomotor nerve, and the dilation of the pupil is accomplished by the pupillary dilator muscle innervated by the sympathetic nerve. The reflex on the same side is called the direct light reflex,...
