Abstract
The invention discloses a binocular vision detector. The binocular vision detector comprises an image sensor (1), an imaging lens (2), a semi-transmitting and semi-reflecting prism (3), a third shutter (9), a sighting mark imaging lens (10), a sighting mark (11), a collecting lens (12) and a sighting mark lamp (13) which are arranged on a primary optical axis (21) in sequence. A first reflector (4), a first shutter (5) and a first annular light source seat (6) are arranged on a right sight axis (22) in sequence. A left sight axis (23) and the right sight axis (22) are symmetrically arranged. A hardware driving module (19) can control the image sensor (1), all the shutters and all the light sources. According to the binocular vision detector, by means of the semi-transmitting and semi-reflecting prism, the same imaging lens is used for shooting of the left eye and the right eye, the same image sensor is used, and the sighting mark observed by the left eye and the right eye is the same real sighting mark. The binocular vision detector has the advantages that imaging consistency is good, the whole device cost is effectively reduced, it is ensured that the vision of human eyes are tested at the real vision state, and the detection of the left eye and the right eye is completed at a time.
Description

In order to solve existing eyesight detecting instrument cannot human eye be in truly look thing state time disposable detection about the problem of two eyes, the invention provides binocular vision detector, this binocular vision detector uses same imaging lens by right and left eyes shooting, same imageing sensor, timesharing shooting is independent of each other.There is imaging consistency good, reduce the feature of complete machine cost.
Technical scheme of the present invention is: a kind of binocular vision detector comprises imageing sensor (1), imaging lens (2), semi-transparent semi-reflecting prism (3), illuminator 1 (4), shutter 1 (5), ring light source(-)holder 1 (6), infrared LED lamp 1 (7), shutter 3 (9), sighting target imaging lens (10), sighting target (11), condenser lens (12), sighting target lamp (13), illuminator 2 (14), shutter 2 (15), ring light source(-)holder 2 (16), infrared LED lamp 2 (17), Hardware drive module (19), PC (20).Primary optical axis (21) and right sight axle (22), left sight axle (23) are vertically intersected on semi-transparent semi-reflecting prism (3) center.Sighting target lamp (13) is by condenser lens (12) illumination sighting target (11), and sighting target (11) is by sighting target imaging lens (10), shutter 3 (9), semi-transparent semi-reflecting prism (3) imaging.Right and left eyes is by the picture of left sight axle (23), right sight axle (22) observation sighting target (11).Infrared LED lamp 1 (7) illumination right eye (8), right eye is imaged on imageing sensor (1) by shutter 1 (5), illuminator 1 (4), semi-transparent semi-reflecting prism (3), imaging lens (2).Infrared LED lamp 2 (17) illumination left eye (18), left eye is imaged on imageing sensor (1) by shutter 2 (15), illuminator 2 (14), semi-transparent semi-reflecting prism (3), imaging lens (2).Hardware drive module (19) controls shutter 1 (5), shutter 2 (15), shutter 3 (9), infrared LED lamp 1 (7), infrared LED lamp 2 (17), sighting target lamp (13), imageing sensor (1).PC (20) is connected with Hardware drive module (19).
Described shutter 1 (5), shutter 2 (15), shutter 3 (9) can be mechanical shutter or light valve glass.
Described infrared LED lamp 1 (7), infrared LED lamp 2 (17) are even or be symmetrically distributed in ring light source(-)holder.
Described right and left eyes shooting uses same imaging lens (2) and same imageing sensor (1).
The sighting target (11) of described right and left eyes observation is same true sighting target.
The present invention has following beneficial effect: right and left eyes shooting uses same imaging lens, same imageing sensor; The sighting target that right and left eyes is observed is same true sighting target; Sighting target light path and right and left eyes imaging optical path are separately.Have imaging optical path not by the stray light of sighting target luminous power, guarantee that human eye is truly looking thing state verification vision, right and left eyes timesharing shooting is independent of each other, and imaging consistency is good, effectively reduces the features such as complete machine cost.
