Category	Types of structure	Advantages	Disadvantages
Plane mirror-basedbinocular visionsystem	Symmetry	1) The parameters of the virtualcamera generated by a singlemirror is the same, which cansimplify the calibrationprocess effectively
Plane mirror-basedbinocular visionsystem	Non-symmetry	2) Avoid the synchronousacquisition of images in leftand right view andimprove the efficiency ofimage acquisition3) The close distancebetween the camera and themirror makes it easy todesign the sensor structure4) Baseline distance is largeand easy to configure thefield of view	1) The measured fieldof view is half2) Different image resolutionsmake the matchingaccuracy reduce3) The changing field-of-viewdirection makes the configurationof the measuredobject difficult4) The unequal optical pathmeasurement reducesthe measurement accuracy
Curved mirror-basedbinocularvision system	Symmetry	1) The field of view isomnidirectional2) The parameters of thevirtual camera generated bya single mirror are the same,which can simplify thecalibration process effectively3) Avoid the synchronousacquisition of images in leftand right view and improvethe efficiency ofimage acquisition	1) Inherent curing exists in images2) The target features do not have theperspective projection invariance3) The resolution of the same targethas a large difference4) The measurement model is complex
