Embodiment 1

[0058] This embodiment introduces the main structure and functions of the compound eye imaging device of the present invention.

[0059] figure 1 It is a structural schematic diagram of a compound eye imaging device according to an embodiment of the present invention. refer to figure 1 , In one embodiment, the compound eye imaging device includes the above-mentioned ommatidium column and a processor.

[0060] Specifically, the compound eye imaging device may include one or more than two ommatidium rows, a plurality of ommatidium rows may form an ommatidium array, and a clip is formed between the viewing planes of different ommatidium rows. angle, each of the ommatidia belongs to one or more than two ommatidia columns. For the same described ommatidium row, each ommatidium can include one or more than two (including two) photosensitive units, and the line of sight of each photosensitive unit is all on a plane, so it can be formed as two lines that intersect or do not interse...

Embodiment 2

[0071] This embodiment mainly introduces the ommatidium column of the compound eye imaging device of the present invention.

[0072]Fig. 2(a) is a schematic diagram of imaging of the ommatidium column in an embodiment of the present invention. Fig. 2(b) is a schematic diagram of imaging of an ommatidium in Fig. 2(a). Fig. 2(c) is a schematic diagram of the optical center cone and pixel surface sensing light beam corresponding to a photosensitive unit in Fig. 2(a).

[0073] Referring to FIG. 2( a ) and FIG. 2( b ), the incident light beams L1 , L2 and L3 enter the ommatidium column 100 and project into each ommatidium 10 along the line of sight of the photosensitive units in each ommatidium. After the parallel light beam is incident on the optical center C of the ommatidium 10 (more specifically, the optical center of the optical element in the ommatidium), it is focused on the focal plane 10a, that is, any focal point corresponds to the point parallel to the line connecting t...

Embodiment 3

[0087] This embodiment mainly introduces the specific structure of the compound eye imaging device according to the embodiment of the present invention.

[0088] In the ommatidium row in the compound eye imaging device of the present invention, the optical element in each ommatidium can be a microlens, and the microlens is a convex lens here, and its focal plane is positioned at the opposite side to the subject, and the ommatidium described below is a microlens Described for optical components. But the present invention is not limited thereto, in another embodiment, the optical element of at least one ommatidium can also be a compound imaging objective lens comprising a plurality of optical components (such as one or more lenses, filters and / or apertures). In a biomimetic sense, the function of the optical element in the ommatidium is similar to that of the lens in the monocular eye of compound eyes. The photosensitive units corresponding to the same optical element in the af...

Abstract

The invention relates to a compound eye camera device and a compound eye system. The compound eye camera device comprises a plurality of small eyes arranged in a row or a column, each small eye comprises an optical element and a corresponding photosensitive unit, and each small eye column at least corresponds to one small eye column view plane. The ommatidium array view plane passes through the optical center of each ommatidium in the ommatidium array and the center of at least one light sensing unit of each ommatidium, each light sensing unit is at least intersected with the ommatidium array view plane, and the sight line of each light sensing unit passes through the center of the light sensing unit and the optical center of the ommatidium where the light sensing unit is located. The processor is configured to generate an image based on the information received by the photosensitive unit, and process the image to obtain information about the subject. The compound eye system can comprise the compound eye camera device. By using the compound eye camera device, two-dimensional plane or three-dimensional detection can be carried out from different directions, and accurate two-dimensional and three-dimensional space information can be acquired.

Description

technical field [0001] The invention relates to the field of optical imaging, in particular to a compound eye imaging device and a compound eye system. Background technique [0002] In the animal kingdom, compound eyes refer to a visual organ composed of a large number of single eyes, which mainly appear in arthropods such as insects and crustaceans. Taking compound eye insects as an example, each single eye in the compound eyes has a lens (similar to Microlenses) and photoreceptor cells corresponding to the lens, these photoreceptor cells will transmit photosensitive information to the insect's brain nervous system, thereby effectively calculating the orientation and distance between itself and the observed object, that is, realizing stereo vision, which is beneficial to compound eyes Insectoids make quick judgments and responses. [0003] Artificial compound eye technology is a technology developed inspired by the unique compound eye structure of animals. Compared with t...
