Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art belong to the scope of protection of the present application.

It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than that illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually a category and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in a "or" relationship.

[0042] 1. In the description of the present application, it should be understood that the terms "up", "down", "front", "back", "left", "right", "in", "out" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the present application and simplify the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0043] 2. In the description of the present application, "a plurality of" means two or more.

[0044] The following refers to Figures 1 to 6 The light source device 100 provided by the embodiments of the present application is described below.

[0045] As Figure 1 and Figure 3 shown, the light source device 100 includes a semi-capsule mechanism 110, a base 120, and a light strip 130.

[0046] In this embodiment, the semi-capsule mechanism 110 is a hollow structure, and the semi-capsule mechanism 110 has an internal space, which can be closed or partially open.

[0047] The bottom of the semi-capsule mechanism 110 can have an opening, and the opening part allows light to be reflected on the inner wall of the semi-capsule mechanism 110.

[0048] The base 120 can provide support for the semi-capsule mechanism 110, and the base 120 is connected to the bottom opening of the semi-capsule mechanism 110 to form a containing cavity together.

[0049] The base 120 has a hole opposite the containing cavity, which is a channel for light to exit from the inside of the device, and the size and position of the hole can be adjusted as needed to control the exit angle and range of light.

[0050] As shown in Figure 3 The lamp strip 130 is arranged on the side of the base 120 facing the containing cavity, that is, the lamp strip 130 can be positioned inside the semi-capsule mechanism 110, so that the light emitted by the lamp strip 130 can directly irradiate the inner wall of the semi-capsule mechanism 110.

[0051] The lamp strip 130 can be closely arranged around the hole, or can be dispersedly arranged based on a certain spacing.

[0052] The light emitted by the lamp strip 130 is reflected on the inner wall of the semi-capsule mechanism 110 and exits through the hole.

[0053] The light emitted by the lamp strip 130 can be monochromatic or multicolored, and can be dimmed and colored according to actual detection needs, and the shape and size of the lamp strip 130 can be customized by the user, which is not limited by the present application.

[0054] When the lamp strip 130 is powered on and emits light, the light emitted by the lamp strip 130 first irradiates the inner wall of the semi-capsule mechanism 110, and the light is reflected multiple times on the inner wall, thereby enhancing the brightness and changing the direction. The reflected light exits through the hole in the base 120 to provide illumination conditions for industrial detection (such as defect detection).

[0055] According to the light source device 100 provided by the embodiment of the present application, by arranging the semi-capsule mechanism 110 with a bottom opening, and arranging the lamp strip 130 on the base 120 at the bottom opening, the light emitted by the lamp strip 130 can be reflected on the inner wall of the semi-capsule mechanism 110, which enriches the light exit angle of the light exiting from the hole, improves the utilization rate of the light source, and improves the overall illumination efficiency.

[0056] In some embodiments, the semi-capsule mechanism 110 can include a semi-elliptical cylinder and two quarter-elliptical cylinders.

[0057] In this embodiment, the semi-elliptical cylinder is a hollow structure, and the semi-elliptical cylinder has an open semi-elliptical space inside, which is used for light reflection and propagation.

[0058] The end surface of the semi-elliptical cylinder is semicircular or semi-elliptical.

[0059] The height and length of the semi-elliptical cylinder can be customized based on the size of the measured workpiece, which is not limited in the present application.

[0060] The two quarter-ellipsoids are correspondingly arranged at the two ends of the semi-elliptical cylinder, the shapes and sizes of the two planar end surfaces of the semi-elliptical cylinder match the corresponding parts of the quarter-ellipsoids, and the semi-elliptical cylinder and the two quarter-ellipsoids can be tightly and seamlessly combined together to form a continuous and complete internal space.

[0061] The quarter-ellipsoids are hollow structures, and the hollow structures of the two quarter-ellipsoids and the hollow structure of the semi-elliptical cylinder form the hollow structure of the semi-capsule mechanism 110.

[0062] The radius of the quarter-ellipsoids can be customized based on the size of the measured workpiece, which is not limited in the present application.

[0063] The inventor found in the development process that there is a dome light source in the related art, which is bowl-shaped. In the industrial detection process, for a rectangular measured workpiece, the light emitting surface size of the dome light source is often greater than the long side of the measured workpiece, thereby causing the overall size of the dome light source to be large and the material consumption to be more.

[0064] In the present application, by setting the light source device 100 as a semi-capsule type, and the height and length of the semi-elliptical cylinder in the semi-capsule mechanism 110, and the radius of the quarter-ellipsoids can be adjusted based on the size of the measured workpiece. In the case that the size of the measured workpiece is the same, the overall size and volume of the light source device 100 in the present application are smaller than those of the dome device in the related art, and the material consumption is less.

[0065] According to the light source device 100 provided in the embodiments of the present application, by setting the semi-elliptical cylinder and the two quarter-ellipsoids, a mutually communicating accommodating cavity can be formed, which provides a relatively rich light exit angle and makes the light source device 100 have a smaller volume.

[0066] In some embodiments, the longitudinal section of the quarter-ellipsoids is semicircular or semi-elliptical, and the transverse section of the quarter-ellipsoids is semicircular or semi-elliptical.

[0067] In this embodiment, the longitudinal section of the quarter-ellipsoids matches the shape and size of the end surface of the semi-elliptical cylinder.

[0068] The longitudinal section of the quarter-elliptic is perpendicular to the plane of the base 120 and parallel to the end face of the semi-elliptic cylinder.

[0069] The cross section of the quarter-ellipsoid is parallel to the plane of the base 120, and the cross section is perpendicular to the longitudinal section.

[0070] An ellipsoid can be a sphere or an ellipsoid.

[0071] In some embodiments, the inner radius of the longitudinal section of the quarter-elliptic is equal to the inner radius of the end face of the semi-elliptic cylinder.

[0072] In some embodiments, the outer radius of the longitudinal section of the quarter-elliptic is equal to the outer radius of the end face of the semi-elliptic cylinder.

[0073] In this embodiment, the inner radius is the distance from the center of the ellipse or circle containing the cross-section to the inner boundary; the outer radius is the distance from the center of the ellipse or circle containing the cross-section to the outer boundary.

[0074] The shell thickness of the quarter-elliptic body is equal to that of the semi-elliptic cylinder. The quarter-elliptic body and the semi-elliptic cylinder can be fitted together to form a smooth outer shell and inner wall of the semi-capsule-shaped mechanism 110.

[0075] In some embodiments, the inner wall of the semi-capsule-shaped mechanism 110 is coated with a diffuse reflection coating.

[0076] In this embodiment, diffuse reflection is the phenomenon of light projected onto a rough surface being reflected in all directions. When a beam of parallel incident light hits a rough surface, the surface reflects the light in all directions. By coating the inner wall of the semi-capsule with a diffuse reflection layer, light can be diffusely reflected on the coating surface.

[0077] The diffuse reflection coating has a high reflectivity and Lambertian properties, which allows the light emitted from the light strip 130 to be reflected more and more evenly after hitting the inner wall of the semi-capsule-shaped mechanism 110, thus providing better lighting conditions for industrial inspection.

[0078] like Figure 6 As shown, in some embodiments, the base 120 is provided with at least one interface 140.

[0079] In this embodiment, the interface 140 is disposed outside the semi-capsule-shaped mechanism 110, and the interface 140 may be disposed on the rear plate of the base 120.

[0080] At least one interface 140 can be one or more, such as Figure 6 Five interfaces, 140, are shown as examples.

[0081] One end of interface 140 is connected to the light strip 130.

[0082] In some embodiments, the other end of the interface 140 is connected with the controller through the light source serial port.

[0083] In this embodiment, the light strip 130 can be divided into a plurality of lighting partitions, for example, 1 / 4 radian of the light strip 130 can be divided into one lighting partition, or 1 / 8 radian of the light strip 130 can be divided into one lighting partition, which is not limited in the present application.

[0084] One interface 140 can be connected with the light strip 130 of one lighting partition.

[0085] The controller can set the light source serial port of the same channel to control the stroboscopic lighting of the light sources of each partition.

[0086] According to the light source device 100 provided in the embodiments of the present application, the controller controls the stroboscopic lighting of the light strip 130 of each partition through the light source serial port, which improves the flexibility and diversity of lighting, and the interface 140 is set to be connected with the light strip 130 and the controller respectively, which improves the expansibility and adaptability of the light source device 100.

[0087] In some embodiments, the light strip 130 includes a plurality of lamp beads.

[0088] In this embodiment, the plurality of lamp beads are connected in series or in parallel through wires to form a continuous lighting strip.

[0089] The central axis of the lamp bead is perpendicular or inclined to the plane of the base 120, that is, the central axis of the light-emitting direction of the lamp bead is perpendicular or inclined to the plane of the base 120.

[0090] In the case that the central axis of the lamp bead is perpendicular to the plane of the base 120, the light of the lamp bead can be directly emitted towards the inner wall of the semi-capsule mechanism 110, forming a uniform and concentrated lighting effect.

[0091] The lamp beads can be arranged correspondingly with the change of the radian of the semi-capsule mechanism 110, and in the case that the central axis of the lamp bead is inclined to the plane of the base 120, the light of the lamp bead has a certain directivity when emitted, so as to change the distribution of the lighting effect, and by adjusting the inclination angle, the diffusion degree of the light in the horizontal direction and the vertical direction can be controlled.

[0092] In some embodiments, the light strip 130 can include at least one circle of lamp beads.

[0093] In this embodiment, the number of arranged circles of lamp beads can be customized by the user, for example, the number of arranged circles of lamp beads can be one, two or other numbers, which is not limited in the present application.

[0094] As shown in FIG. 1, the light source device 100 includes a semi-capsule mechanism 110, a base 120, a light strip 130, an interface 140 and a controller 150. Figure 1 Or Figure 2As shown, in some embodiments, the housing of the semi-capsule-type mechanism 110 includes an opening structure 150.

[0095] In this embodiment, the opening structure 150 can be provided at the top of the housing, that is, it can be provided at the top of the semi-elliptical cylinder housing.

[0096] The opening structure 150 can be rectangular, and the size of the opening structure 150 can be customized by the user.

[0097] The opening structure 150 is the observation aperture of the image sensor.

[0098] The opening structure 150 is used for the image sensor to acquire images of the object under test.

[0099] An image sensor is disposed on the housing side of the semi-capsule-type mechanism 110, and the opening structure 150 is within the field of view of the image sensor.

[0100] The object to be tested is placed on the hollow side of the semi-capsule-type mechanism 110 and within the field of view.

[0101] The object to be tested can be a workpiece with high reflectivity, such as metal, alloy, coated product, or glass.

[0102] For example, the light source device 100 is placed horizontally, and the bottom opening of the semi-capsule-shaped mechanism 110 faces downward. An opening structure 150 can be provided on the top of the shell of the semi-capsule-shaped mechanism 110. The image sensor is placed directly above the semi-capsule-shaped mechanism 110, with the observation direction of the image sensor facing the opening structure 150, so that the opening structure 150 is within the field of view of the image sensor. The object to be measured is placed directly below the semi-capsule-shaped mechanism 110, so that the light reflected by the inner wall of the semi-capsule-shaped mechanism 110 can illuminate the object to be measured. Then, the image sensor can be controlled to acquire an image of the object to be measured, and industrial inspection can be performed based on the acquired image.

[0103] like Figure 6 As shown, in some embodiments, the rear plate of the base 120 includes threaded holes.

[0104] In this embodiment, the threaded hole can be used to mount the image sensor's mounting bracket.

[0105] like Figure 5 As shown, in some embodiments, the light source device 100 may also include at least one side plate.

[0106] In this embodiment, at least one side plate may be disposed around the base 120. For example, four side plates may be disposed around the base 120.

[0107] The shape and size of the side plate can be set based on actual needs, for example, the side plate can be rectangular, circular, or arc-shaped, etc., which is not limited in the present application.

[0108] There is a gap between the side plate and the half-capsule type mechanism 110.

[0109] The side plate can be used to protect the internal light source assembly from external physical damage, such as collision, dust and moisture, etc.

[0110] As shown in some embodiments, a first heat dissipation device can be provided at the gap between the side plate and the half-capsule type mechanism 110. Figure 4

[0111] In this embodiment, the first heat dissipation device can include a fan and / or a heat sink.

[0112] The fan can carry away the heat inside the light source device 100 to reduce the operating temperature of the light source device 100.

[0113] The heat sink can improve the heat dissipation efficiency by increasing the surface area, and the shape and size of the heat sink can be set based on different heat dissipation needs, which is not limited in the present application.

[0114] In some embodiments, the light source device 100 can further include a second heat dissipation device.

[0115] In this embodiment, the second heat dissipation device can be a vent.

[0116] The vent can be opened on the side plate to increase the air flow, further reducing the operating temperature of the light source device 100.

[0117] The size, number and position of the vent can be set based on actual needs, which is not limited in the present application.

[0118] In actual implementation, the first heat dissipation device and the second heat dissipation device can be integrated and used together to form a heat dissipation system.

[0119] The present application also provides an imaging system.

[0120] The imaging system includes a light source device 100, an image sensor and a controller.

[0121] In this embodiment, the controller can be connected to the light source device 100 and the image sensor respectively.

[0122] The light source device 100 can be a stroboscopic light source, which can flash at a specific frequency to provide instantaneous illumination.

[0123] ​The controller can be a stroboscopic controller, the controller can be configured to control the flashing of the light source, the controller can receive an external signal, and control the lighting and extinguishing of the light source device 100 according to the external signal.

[0124] The image sensor can be a line scan camera or a face array camera.

[0125] In some embodiments, the imaging system can include a capture card.

[0126] In this embodiment, the capture card is connected to the controller and the image sensor, respectively.

[0127] In the line scan scenario, the controller can control the lighting of the light source device 100 and the image acquisition of the image sensor based on the following control logic:

[0128] As shown in Figure 7 , after receiving the external signal, the controller can send an action signal to the light source device 100 and the capture card at the same time, and the capture card can control the image sensor to acquire images in a very short time after receiving the signal, so as to realize the synchronization of the flashing of the light source device 100 and the acquisition of the image sensor.

[0129] As shown in Figure 8 , the capture card can receive an external signal and send an action signal to the controller and the image sensor at the same time after receiving the external signal, and the controller can control the light source device 100 to light in a very short time after receiving the signal, so as to realize the synchronization of the flashing of the light source device 100 and the acquisition of the image sensor.

[0130] In actual execution, the light source device 100 can include multiple stroboscopic partitions, for example, in the case of 8 stroboscopic partitions in the light source device 100, in one cycle, the stroboscopic partitions can be lit in turn according to the order of the partitions, the light source device 100 will be lit 8 times, and the capture card can continuously receive all the images and split the images according to the number of partitions, so as to output 8 images under different partition lighting, so as to improve the flexibility and resolution of imaging.

[0131] As shown in Figure 9 , in the face array scenario, when the sample to be measured is placed on the stage, the stage can send an external signal to the controller, and the controller can send a trigger signal to the light source device 100 and the image sensor at the same time after receiving the signal, so as to realize the synchronization of the light emission of the light source device 100 and the acquisition of the image sensor.

[0132] Similar to the line scan scenario, the light source device 100 can also include multiple stroboscopic partitions, which will not be described here.

[0133] In some embodiments, the light source device 100 can be a constant light device.

[0134] In the present application, by using the partition stroboscopic control light source device 100 to light, the lighting partition and lighting order in each acquisition cycle and the color of the lamp beads of each partition can be customized based on user needs, improving the configurability of the imaging system, and improving the accuracy and richness of the reconstructed three-dimensional information, suitable for more detection scenarios.
