The imaging module 22 is located at the rear side of the light source module 21, and the lens 221 of the imaging module 22 is coaxially arranged with the main board light-transmitting hole 2111.

When imaging module 22 is in the commissioning state, all test light sources 212 are in the illuminated state.

When the imaging module 22 is in the imaging state, the main light source group 213 is sequentially turned on according to a preset lighting sequence of the main light source group, and the plurality of main light sources 214 in the main light source group 213 are sequentially turned on according to the preset lighting sequence of the main light sources 214.

In this embodiment, the light source module 21 includes a main board 211, a plurality of commissioning light sources 212, and a plurality of main light source groups 213.

The main board 211 is a printed circuit board, and a main board light-transmitting hole 2111 is formed in the middle of the main board 211. The main board 211 is communicatively connected to the main control unit 3.

A plurality of commissioning light sources 212 and a pair of main light source sets 213 are respectively installed on the front side of the main board 211 and are respectively arranged around the main board light transmission holes 2111. Each of the main light source groups 213 includes a plurality of main light sources 214, and the plurality of main light sources 214 are arranged along a radial direction of the main plate light transmission hole 2111.

The commissioning light source 212 is used when the imaging module 22 is commissioned. The imaging module 22 automatically adjusts the exposure time according to the brightness of the debugging light source 212 and the environment, so as to quickly take a picture meeting the requirement. If the light intensity of the photographing environment is greater than the light intensity threshold value, the exposure time is increased.

The primary light source 214 is used when the imaging module 22 takes a picture to provide an off-center light source. Both the commissioning light source 212 and the main light source 214 are infrared light sources.

Each of the main light sources 214 in the main light source group 213 is an eccentric light source, different main light sources 214 in each main light source group 213 have different distances from the center of the main plate light-transmitting hole 2111, and when the main light sources 214 at different positions are turned on, the image data obtained by the imaging module 22 is slightly different. By shooting multiple sets of image data and averaging at last, the measurement accuracy can be improved.

The illumination of the primary light source 214 forms an infrared-decentered optical path system with the entire optical path. The light from the eccentric primary light source 214 enters the eye, and due to the refractive state of the eye, the incident light forms a diffuse spot on the retina, which diffusely reflects on the retina, and the light is projected through the pupil into the imaging module 22 for imaging. The pupil images captured by the imaging module 22 differ according to the refractive state of the eye being measured. When the refractive state of the human eye is normal, the gray level in the pupil shot by the imaging module 22 is uniform without light and shade difference; when the refractive state of the human eye is abnormal (myopia or hyperopia), the gray level in the pupil shot by the imaging module 22 has obvious brightness difference, and the brightness difference reflects the degree of the myopia or hyperopia.

The primary light sources 214 are individually illuminated in a predetermined sequence, and different pupil images can be sequentially obtained to obtain a more accurate refractive state of the human eye.

In one embodiment, as shown in fig. 3 to 5, the main board 211 has a plurality of main light source arrays 215 thereon, each main light source array 215 includes two main light source groups 213, and the two main light source groups 213 are symmetrically arranged around the main board light-transmitting hole 2111.

When the imaging module 22 is in the imaging state, the plurality of main light source arrays 215 are sequentially turned on according to a preset lighting sequence of the main light source arrays.

When each of the primary light source arrays 215 is in an illuminated state, the primary light sources 214 in the two primary light source groups 213 are alternately sequentially illuminated in an outside-in order.

In this embodiment, the even number of first infrared light sources 312 and the even number of main light source groups 213 are disposed on the main board 211. The even number of first infrared light sources 312 and the even number of main light source groups 213 are staggered with each other.

As shown in fig. 3-5, the main board 211 has 6 main light source groups 213 thereon. The X-axis in fig. 4 is set to the horizontal radial direction of the main plate light transmission hole 2111, and the Y-axis is the vertical radial direction of the main plate light transmission hole 2111. The included angle between the main light source group 213 and the X-axis represents the direction of the main light source group 213, for example, 30 °, 60 °, 120 °, etc., and by measuring the spherical power in each direction, a more accurate diopter parameter can be obtained.

Two main light source groups 213 symmetrically arranged with the center of the main plate light-transmitting hole 2111 constitute one main light source array 215. When the imaging module 22 is in the photographing state, the main light source arrays 215 are sequentially turned on, and only one second infrared light source 313 of one main light source group 213 on one side in one main light source array 215 is turned on at a time. When each main light source array 215 is lighted, the main light sources 214 in the two main light source groups 213 with central symmetry are lighted in sequence from outside to inside alternately. That is, the outermost primary light source 214 in the first primary light source group 213 is lit first, then the outermost primary light source 214 in the second primary light source group 213 is lit, then the second primary light source 214 from the outside to the inside in the first primary light source group 213 is lit, then the second primary light source 214 from the outside to the inside in the second primary light source group 213 is lit, and so on, so that the primary light sources 214 are lit alternately in a central symmetric manner as much as possible. When every two symmetrical main light sources 214 are turned on, the two sets of image data captured by the imaging module 22 have extremely high similarity.

As shown in fig. 5, illustrated is a horizontally arranged array of primary light sources 215: the primary light sources 214 in the two primary light source groups 213 are sequentially lit in the order i, ii, iii, iv, v, vi.

In one embodiment, as shown in fig. 3-5, the main board 211 further has a plurality of compensating light sources 216 thereon.

Wherein all of the compensating light sources 216 are simultaneously illuminated when any one of the primary light sources 214 is illuminated.

The compensating light source 216 performs a compensating function. The compensating light source 216 is farthest from the center of the main plate light-transmitting hole 2111, and has a light-emitting angle and a light-emitting range different from those of the main light source 214. The main control unit 3 may control the switching of the compensating light source 216.

When the main light source 214 is turned on, the image data captured by the imaging module 22 may be converted into corresponding parameter data, such as a gray scale gradient, by the data image processing module 23.
