Referring to fig. 1 and 2, the image capturing apparatus provided by the present utility model includes a base plate 100, a camera assembly 200, a first rotating assembly 300, and a second rotating assembly 400.

Wherein the base plate 100 may be a bread board or an optical platform. The structure of the base plate is not particularly limited in this embodiment.

The axis direction of the first rotating assembly 300 coincides with the X-axis direction in fig. 1, and the axis of the second rotating assembly 400 coincides with the Z-axis direction in fig. 1.

The first rotating member 300 rotates about an axis, and the second rotating member 400 is driven to rotate relative to the base plate 100, so that the sample 500 can be driven to rotate about the axis of the first rotating member 300, that is, in the X-axis direction. The second rotating assembly 400 rotates about an axis to drive the rotation of the sample 500 relative to the first rotating assembly 300 such that the sample 500 can rotate about the axis of the second rotating assembly 400, that is, about the Z-axis. Therefore, the rotation of the sample 500 around two directions can be achieved by the first and second rotation assemblies 300 and 400, so that the camera assembly 200 collects image information of the sample 500 at different angles.

The image capturing apparatus provided in this embodiment is configured by providing the base plate 100, the camera assembly 200, the first rotating assembly 300, and the second rotating assembly 400.

The second rotating assembly 400 is used for placing the sample 500, and the second rotating assembly 400 rotates around an axis to drive the sample 500 to rotate relative to the first rotating assembly 300, wherein the axis of the second rotating assembly 400 is perpendicular to the plane of the base plate 100. The camera assembly 200 is located at one side of the second rotating assembly 400, and the camera assembly 200 is used to photograph the sample 500. In this way, rotation of the sample 500 about two directions may be achieved, thereby allowing the camera assembly 200 to capture image information of the sample 500 at different angles. The photographing angles of the sample 500 can be controlled by controlling the rotation angles of the first and second rotary members 300 and 400, and the photographing angles can be reproduced. Therefore, the controllability of image acquisition is high.

It will be appreciated that the center of the projection of the camera 220 toward the plane of the base plate 100 coincides with the axis of the second rotating assembly 400, and thus, the camera 220 is located directly above the sample 500, and the color information obtained by photographing the sample 500 is rich.

Specifically, the camera 220 is a fixed-focus camera.

For example, the photographing angle of the camera 220 may be 46 °, and the photographing angle of the camera 220 is not particularly limited in this embodiment.

Illustratively, the distance a between the side of the camera 220 facing the base plate 100 and the side of the second rotating assembly 400 facing away from the base plate 100 is 25cm or 30cm.

When the distance a between the side of the camera 220 facing the base plate 100 and the side of the second rotating assembly 400 facing away from the base plate 100 is smaller than 20cm, the second rotating assembly 400 is liable to collide with the camera 220 when the first rotating assembly 300 rotates.

When the distance a between the side of the camera 220 facing the base plate 100 and the side of the second rotating assembly 400 facing away from the base plate 100 is greater than 35cm, the performance requirement on the camera 220 is high, and the cost is high.

For example, the time period for dividing the image information may be 1S or 2S.

When the time period for dividing the image information is less than 0.15S, the adjacent single-frame image information is less different, the workload of the controller is larger, and the efficiency is lower.

When the time period of dividing the image information is more than 5S, less single-frame image information is obtained.

In some embodiments, the rotational angular velocity of the first rotating assembly 300 is 0.025rad/s to 0.46rad/s.

Illustratively, the rotational angular velocity of the first rotating assembly 300 is 0.1rad/s or 0.2rad/s.

When the rotational angular velocity of the first rotating assembly 300 is less than 0.025rad/s, the rotational angular velocity of the first rotating assembly 300 is slow, the photographing time of the camera 220 is long, and the photographing efficiency is low.

When the rotational angular velocity of the first rotating assembly 300 is greater than 0.46rad/s, the rotational angular velocity of the first rotating assembly 300 is faster, and the photographing effect of the camera 220 is worse.

In this embodiment, the rotational angular velocity of the second rotating assembly 400 is 0.025rad/s to 0.46rad/s.

Illustratively, the rotational angular velocity of the second rotating assembly 400 is 0.1rad/s or 0.2rad/s.

Similarly, when the rotational angular velocity of the second rotating assembly 400 is less than 0.025rad/s, the rotational angular velocity of the second rotating assembly 400 is slower, the photographing time of the camera 220 is longer, and the photographing efficiency is lower.

When the rotational angular velocity of the second rotating assembly 400 is greater than 0.46rad/s, the rotational angular velocity of the second rotating assembly 400 is faster, and the photographing effect of the camera 220 is worse.

It can be appreciated that by limiting the rotational speed of the first rotating assembly 300 and the second rotating assembly 400, clear contours and accurate chromaticity of the sample 500 in the image captured by the camera 220 can be ensured.

In some embodiments, the rotational linear speed of the first rotating assembly 300 is 1.17mm/s-23mm/s. The rotational linear velocity of the second rotary member 400 is 1.17mm/s to 23mm/s.

Illustratively, the rotational linear velocity of the first rotating assembly 300 may be 5mm/s or 10mm/s. The rotational linear velocity of the second rotary assembly 400 may be 5mm/s or 10mm/s.

It can be appreciated that by limiting the rotational linear speeds of the first rotating assembly 300 and the second rotating assembly 400, clear contours and accurate chromaticity of the sample 500 in the image acquired by the camera 220 can be ensured.
