1. A monitoring device, comprising a carrying unit, the carrying unit is provided with at least one carrying area for carrying a monitored object, and at least part of the carrying area is provided with a corresponding image capturing unit and a corresponding optical path adjusting unit; wherein
the image capturing unit is configured to capture a monitoring image of the carrying area corresponding to the image capturing unit, and the image capturing unit is provided with a preset field of view and is configured to form the monitoring image according to light emitted from the field of view;
at least part of the carrying area having the corresponding image capturing unit and the corresponding optical path adjusting unit is an extension area, and the extension area is positioned outside the field of view of the image capturing unit corresponding to the carrying area where the extension area is positioned;
the optical path adjusting unit is configured to enable the light emitted from the extension area of the carrying area corresponding thereto to enter the image capturing unit from the field of view of the image capturing unit corresponding to the carrying area, wherein
at least a part of optical path adjusting units is a concave lens, and the concave lens is arranged between the image capturing unit corresponding thereto and the carrying area, and is configured to refract light emitted from the extension area of the carrying area corresponding to the concave lens, so that the refracted light is incident into the image capturing unit from the field of view of the image capturing unit corresponding to the carrying area, and wherein
the field of view of the image capturing unit corresponding to the concave lens faces the carrying area corresponding to the concave lens, and the field of view of the image capturing unit is completely located within the range of the concave lens.
