Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.

[0031] In the professional micro distance shooting field, depth of field stack shooting is a commonly used technology. In micro distance shooting, because the depth of field is very shallow, usually, different focal plane photos of multiple even dozens or hundreds of photos need to be stacked to synthesize the full depth of field photo. For example, a single-lens reflex camera is installed on a support single-lens reflex camera moving slide, then every time a picture is shot, the user operates the slide to displace several microns and continuously shoots. However, by this shooting mode, different focal plane photos of multiple even dozens or hundreds of photos need to be shot, the single-lens reflex camera needs to be installed on a slide in a fixed environment, which is inconvenient to carry, and the operation of the slide to shoot multiple photos is very time-consuming and laborious.

[0032] In view of the above, it is necessary to provide a shooting device which is strong in portability and can realize depth of field stack shooting.

[0033] In order to solve the above problems, a portable shooting device is provided in the specification, which aims to provide an automatic depth of field stack shooting device, support setting various stack parameters, can control the slide movement and single-lens reflex shooting according to the preset parameters, quickly realize the depth of field stack shooting, so as to solve the problems of time-consuming, laborious and inconvenience when the existing shooting device realizes the depth of field stack. Please refer to Figure 1 、 Figure 2 、 Figure 4 And Figure 5 , the micro device comprises:

[0034] a base 10 for providing mounting positions for other components in the microscope device and for supporting the components, wherein the base 10 is provided with a first mounting interface for mounting the camera controller 90.

[0035] Preferably, the first mounting interface is arranged on a back surface of a main working surface of the base 10 for mounting other components.

[0036] a slide 20 arranged on the base 10, and the base 10 is provided with a slide driving plate 30 for driving the slide 20 to move along a direction horizontal to the base 10. In the embodiment, the slide 20 is used for placing a target to be photographed, i.e., the slide 20 provides a slide space for placing the target to be photographed.

[0037] The direction horizontal to the base 10 includes a transverse direction and a longitudinal direction horizontal to the base 10. Taking an example that the base 10 is placed on a horizontal plane, when the slide driving plate 30 is working, the slide 20 can be driven to move along the X-axis direction or the Y-axis direction, so that when the slide 20 places the target to be photographed, the slide 20 and the target to be photographed placed thereon both change the relative position in the horizontal direction relative to the base 10 under the driving of the slide driving plate 30.

[0038] Preferably, the slide driving plate 30 can be a cross slide driving source such as a double-screw slide, and when the slide driving plate 30 is working, the slide 20 connected to the output end of the slide driving plate 30 can be driven to move along the direction horizontal to the base 10.

[0039] a camera driver 40 arranged on the base 10, and the output end of the camera driver 40 is drivingly connected to a single-lens reflex camera 50, and the single-lens reflex camera 50 is provided with a microscope lens 60 arranged above the slide 20, and the camera driver 40 is used for driving the single-lens reflex camera 50 to move along a direction vertical to the base 10, i.e., the camera driver 40 can drive the single-lens reflex camera 50 to move along the vertical direction of the base 10. In the embodiment, the microscope lens 60 is used for microscopic magnification of the target to be photographed, and the camera driver 40 is provided with a second mounting interface for mounting the camera controller 90.

[0041] The camera controller 90 is a core controller of the shooting device, which is configured to transmit a single-lens reflex camera signal to the single-lens reflex camera 50 to complete a single-lens reflex shooting task of a user, transmit a microscope camera signal to the microscope lens 60 to complete a microscope observation task of the user, transmit a slide table moving signal to the slide table driving board 30 to drive the slide table 20 to move by the slide table driving board 30, so that the target to be shot placed on the slide table 20 can also move to assist in completing the microscope observation task, and transmit a camera moving signal to the camera driver 40 to drive the microscope lens 60 carried on the single-lens reflex camera 50 to move by the camera driver 40 to quickly realize the depth of field stacking shooting.

[0042] In the embodiment, the microscope lens 60 is detachably arranged on the single-lens reflex camera 50, so that the single-lens reflex camera 50 can be used for normal shooting, and the microscope lens 60 can be mounted on the single-lens reflex camera 50 to perform microscope shooting.

[0043] Preferably, the camera driver 40 can be a stepper motor slide table, and an output shaft of the stepper motor slide table is perpendicular to the base 10. A connector matched with the stepper motor slide table is electrically connected with the single-lens reflex camera 50. The camera driver 40 includes the stepper motor slide table and the connector. The connector and the stepper motor slide table are arranged on the base. An output end of the connector is drivingly connected with the stepper motor slide table. An output end of the stepper motor slide table is connected with the single-lens reflex camera 50. When the connector works, the output shaft of the stepper motor slide table can be driven to rotate, and the single-lens reflex camera 50 and the microscope lens 60 carried thereon are driven to move along a direction perpendicular to the base 10. For example, when the camera driver 40 works, the single-lens reflex camera 50 and the microscope lens 60 carried thereon can be driven to move along the Z-axis direction.

[0044] Preferably, the camera controller 90 is a MaixCAM AI single-lens reflex camera, so that the microscope device has an AI vision function and has a human-computer interaction interface (for example, a touch screen) for user control. The size of the single-lens reflex camera 50 is relatively small, for example, the size of the whole machine is controlled to be 5×10×15 cm, and the portability is relatively strong.

[0045] Please refer to Figure 3 and Figure 6In the embodiment, the photographing device has two working modes according to the installation position of the camera controller 90, one is a downward shooting mode in which the camera controller 90 is installed at the first installation interface position, and the downward shooting mode can be used to shoot static indoor targets such as various microscopic observation samples, and the other is a horizontal shooting mode in which the camera controller 90 is installed at the second installation interface position, and the horizontal shooting mode can be used to shoot outdoor targets. The third installation interface is arranged on the camera controller 90 and used to dock with a tripod, so that the user can easily shoot in the horizontal shooting mode when the entire photographing device is placed on the tripod.

[0046] Please refer to Figure 3 In the downward shooting mode, the target to be shot can be placed on the object sliding table 20, and the target to be shot can be moved synchronously when the object sliding table 20 moves, so that automatic focusing can be performed. Specifically, the camera controller 90, the single-lens reflex camera 50, and the microscope lens 60 are turned on, and the target to be shot is placed on the object sliding table 20, so that the microscope lens 60 can obtain an initial image of the object. After the user clicks any position on the human-computer interaction interface of the camera controller 90 that the user wants to focus on, the camera controller 90 calculates the Laplacian value, that is, the definition, of the image of the square within the N-pixel edge length around the focusing point. Then, the camera controller 90 outputs a corresponding camera moving signal to the camera driver 40, and the camera driver 40 drives the single-lens reflex camera 50 and the microscope lens 60 carried thereon to slide downward along the Z-axis direction by a small distance, and the specific value of the distance is determined by the camera moving signal. At this time, if the image shot by the microscope lens 60 becomes clear, the camera controller 90 continues to output a corresponding camera moving signal to the camera driver 40 to control the camera driver 40 to drive the single-lens reflex camera 50 and the microscope lens 60 carried thereon to continue to slide downward along the Z-axis direction. Otherwise, the camera controller 90 generates another sliding control signal, which makes the camera driver 40 drive the single-lens reflex camera 50 and the microscope lens 60 carried thereon to slide in the opposite direction, that is, along the Z-axis direction. The camera controller 90 generates a camera moving signal to drive the microscope lens 60 to slide upward and downward until the microscope lens 60 finds the Z-axis value at which the definition of the target area is the highest and stops, so that the automatic focusing is completed.

[0047] Please refer to Figure 7The shooting device supports setting various stacking parameters, controls the moving of the object placing slide 20 and the shooting of the single-lens reflex camera according to the preset parameters, and quickly realizes the shooting of depth-of-field stacking. Specifically, a user connects the shutter line at the bottom of the slide to the single-lens reflex camera 50, clicks the lifting button on the human-computer interaction interface of the camera controller 90 to control the single-lens reflex camera 50 to the shooting starting point and confirm the starting point, then clicks the lifting button on the human-computer interaction interface of the camera controller 90 to control the single-lens reflex camera 50 to the shooting ending point and confirm the ending point, next, the user inputs the shooting number, stabilization time, slide return difference and other parameters on the human-computer interaction interface of the camera controller 90 and clicks to start shooting, the camera controller 90 calculates the sliding distance of the object placing slide 20 according to the set parameters, waits for stabilization, triggers the shutter line to shoot and automatically moves step by step until the shooting is completed.

[0048] Preferably, the driving source of the slide driving plate 30 can be an 8mm stepper motor, so that the stroke of the X-axis and the Y-axis can be controlled at about 30mm to complete the step-by-step movement.

[0049] In the embodiment, the output end of the stepper motor slide of the camera driver 40 is provided with a magnetic quick-release assembly 80, the single-lens reflex camera 50 is connected to the magnetic quick-release assembly 80, and the magnetic quick-release assembly 80 is magnetically connected to the output end of the stepper motor slide.

[0050] In the embodiment, the single-lens reflex camera 50 is detachably connected to the magnetic quick-release assembly 80, and the single-lens reflex camera 50 is rotatably connected to the magnetic quick-release assembly 80. Through such a setting, the single-lens reflex camera 50 and the microscope lens 60 can be replaced and maintained conveniently, and the user can wipe the microscope lens 60 and change the parameters of the single-lens reflex camera 50 more conveniently and quickly by rotating the single-lens reflex camera 50 on the magnetic quick-release assembly 80.

Through such a setting, the object placing slide 20 becomes a replaceable slide, so that the user can maintain the slide conveniently.
