In some embodiments, the image capture device further includes a display device coupled to the processor 30 such that images captured by the camera 20 may be displayed by the display device.

The processor 30 is a single chip microcomputer or a microprocessor (Micro Controller Unit, MCU), and the processor 30 is disposed inside the rotating member 10 to form a protection for the processor 30 through the rotating member 10. The processor 30 may control the rotation angle, rotation direction and rotation form of the rotator 10 and the camera 20 according to the control signal. For example, the rotator 10 and the camera 20 may be controlled to rotate for a preset period of time as needed.

In some alternative embodiments, the processor 30 is fixed in the rotating member 10, and a heat dissipation member such as a heat dissipation fan or a heat sink may be further disposed in the rotating member 10 to dissipate heat from the processor 30.

In some embodiments, the processor 30 is electrically connected to the alarm unit, and the processor 30 is configured to acquire an image acquired by the camera 20 in real time, and detect that an abnormality exists in a piece to be detected in the image; the control camera 20 is fixed at the current orientation and controls the alarm unit alarm signal. Therefore, the conditions of abnormal quality of the part to be detected or water leakage caused by fire in the area to be detected can be avoided.

When the alarm unit sends out an alarm signal, a worker can check the part to be detected or the area to be detected, so that the worker is prevented from observing the display device for a long time, and the labor intensity of the worker is reduced.

The alarm unit may include a buzzer alarm, and an alarm signal sent by the buzzer alarm is a buzzing sound.

In the rotation process of the camera 20, the light alarm can synchronously rotate along with the lens 21, and the position irradiated by the alarm light is the position where the camera 20 collects images.

The light alarm can supplement light for a piece to be detected or a region to be detected, for example, the light alarm is a fluorescent lamp.

Of course, the light alarm may also only play a role in prompting, and in some alternative embodiments, the propagation direction of the alarm light of the light alarm is parallel to the direction of the camera 20. The light alarm is an infrared laser, and the size of an infrared laser beam emitted by the infrared laser is smaller, so that the infrared laser emitted by the infrared laser can directly irradiate a piece to be detected or a region to be detected, which is currently oriented by the camera 20, and the infrared laser emitted by the infrared laser has an indication function.

Of course, in some alternative embodiments, the image acquisition device may be provided with both a buzzer alarm and a light alarm.

Thus, when the image capturing device is operated, the processor 30 can receive the control signal and control the rotating member 10 and the camera 20 to rotate until the camera 20 faces the position to be monitored. Then, the processor 30 controls the camera 20 to collect images, at this time, the processor 30 may obtain images collected by the camera 20 in real time, and detect whether the to-be-detected member in the images is abnormal, for example, the to-be-detected member may be compared with the pre-stored image information in the processor 30 to determine, when the image information obtained in real time is different from the pre-stored image information, that the current to-be-detected member is abnormal may be determined.

At this time, the processor 30 may control the rotating member 10 and the camera 20 to stop rotating, the lens 21 of the camera 20 faces to the position of the member to be detected where the abnormality occurs currently, and the infrared laser also emits an infrared laser beam to the position of the member to be detected, so that the worker can quickly locate the member to be detected where the abnormality occurs according to the orientation of the camera 20, and the use is convenient.

The processor 30 can also compress and preprocess the collected data such as images, videos and the like, so as to realize the intellectualization of information processing.

The processor 30 may also send the collected data such as images, videos, etc. to the cloud platform, so that the user performs corresponding operations on the cloud platform, and issues an operation instruction to the image collecting device.

In some alternative embodiments, the infrared laser is visible light, and when the infrared laser is arranged in parallel with the camera 20, the infrared laser emitted by the infrared laser can irradiate the part to be detected or the position to be detected, so that the worker is prompted to have an abnormal part to be detected or the position to be detected by the infrared laser, and the infrared laser is convenient to use.

The pieces to be detected may have different abnormal conditions according to the kinds of the pieces to be detected or the kinds of the areas to be detected. When the image capturing device is disposed at the appearance inspection processing station, the camera 20 is configured to capture an appearance image of the part to be inspected, and in some alternative embodiments, detecting that an abnormality exists in the part to be inspected in the image includes detecting that a defect exists on a surface of the part to be inspected. For example, the defect of the detecting member may include an incomplete detecting member, a surface of the detecting member having pits or projections, or the like. When the image acquisition device is arranged at the engraving station, in some alternative embodiments, the surface of the object to be detected is detected without a preset pattern, which can be understood as a preset standard pattern. "without a preset pattern" is understood to mean that the imprinted pattern is incomplete, the imprinted pattern is skewed, the imprinted pattern is erroneous, etc.

Of course, the camera 20 may compare and determine multiple pieces of information of the to-be-detected piece at the same time according to needs, for example, detect that the surface of the to-be-detected piece has a defect and detect that the surface of the to-be-detected piece has no pattern at the same time.

When the to-be-detected piece or the to-be-detected area has a temperature setting requirement, in some alternative embodiments, a thermal infrared imager (not shown) is further arranged on the bracket, and the thermal infrared imager is arranged in parallel with the camera 20 and is used for collecting the temperature information of the to-be-detected piece; the thermal infrared imager is electrically connected with the processor 30, and the processor 30 is used for acquiring temperature information acquired by the thermal infrared imager and controlling the alarm unit to alarm when the temperature is greater than a preset range threshold.

The thermal infrared imager may be of a kind well known to those skilled in the art, and the embodiment is not limited thereto.

The part to be inspected may be a space of a region, for example, inside a warehouse, and may also be understood as a solid part, for example, a workpiece on a production line, or the like. The thermal infrared imager can collect a thermal image of the part to be detected, where the thermal image includes temperature information, so that the camera 20 and the thermal infrared imager can collect appearance information and temperature information of the part to be detected at the same time, so as to avoid overhigh temperature of the part to be detected or the region to be detected.

For example, when the temperature in the area to be detected exceeds a preset threshold, the area has a fire hazard, and at this time, the camera 20 stops rotating and faces the position, and the alarm unit emits infrared laser light.

In some alternative embodiments, the image capturing device may further detect the humidity around the part to be detected, where the image capturing device includes a humidity sensor, and the humidity sensor is connected to the processor 30, so that the humidity information of the part to be detected or the area to be detected may be monitored in real time.

The first driving member 41 may be a driving motor, the output shaft of the first driving member 41 is provided with a driving pulley, the rotating shaft 43 is provided with a driven pulley, and the driving pulley is connected with the driven pulley through a driving belt 42. In this way, the rotation angle and the rotation direction of the rotation member 10 can be controlled by the rotation angle and the rotation direction of the output shaft of the first driving member 41.
