The invention discloses an imaging device and a vehicle, the device comprises an optical waveguide, an image acquisition module and an image output module, and the image acquisition module is in communication connection with the image output module; the optical waveguide is used for splitting incident light to obtain a first light beam and a second light beam, transmitting the first light beam to a target position and transmitting the second light beam to the image acquisition module, the first light beam being visible light, and the second light beam being invisible light; the image acquisition module is used for imaging and processing the second light beam to obtain a target image; and the image output module is used for projecting the target image to the optical waveguide, and the optical waveguide transmits the target image to the target position. In this way, the imaging effect can be improved.

The utility model relates to the technical field of artificial turfs, and provides a multi-scene application prefabricated artificial turf, which comprises a turf main body and a shock pad layer which are connected up and down, and further comprises a connecting piece for connecting the turf main body and the shock pad layer, an axial limiting groove with an inward opening is formed in the inner wall of the drainage hole, one end of the connecting piece is arranged at the bottom of the lawn body, a limiting protrusion is arranged at the other end of the connecting piece in a swinging mode, and the limiting protrusion is configured to be clamped into or not clamped into the axial limiting groove after swinging. According to the technical scheme, the lawn body and the shock pad layer are firmly connected, and the technical problems that in the related technology, the lawn part and the shock pad layer of the artificial lawn are not firmly connected and are prone to falling off are solved.

This utility model provides an invisible display nail, including a female nail and a male nail. The female nail has an inner cavity with an external opening at one end and an axial first screw hole at the other end. A concave portion is located in the middle of the cavity wall. The male nail has an insertion portion on one side and an adhesive portion on the other end face. A convex curved section is located in the middle of the insertion portion. The insertion portion is detachably inserted into the inner cavity, and the convex curved section and the concave portion are interference-fitted to axially limit the male nail. The adhesive portion is located outside the external opening or flush with it, and is used for adhesive connection to external objects. This invisible display nail can easily fix display items to a wall, and since the nail is located behind the display item, no trace of the fastener is visible on the item, thus not affecting its visual effect. It also allows for easy and damage-free removal of the display item from the wall. The male nail is reusable, facilitating the repositioning of the display item.
