Problems solved by technology

[0003] At present, in order to improve the safety of driving a car, a car projection device is usually mounted on the car, and the car projection device transmits the surrounding conditions of the car to the projection device suspended in the car through the imaging device, and the projection device The external image collected by the imaging device will be imaged on the projection screen located on the driver's platform. However, installing the projection screen on the driver's platform of the car will not only occupy a large space on the driver's platform and affect the quality of other equipment. Installation, when there are too many devices installed, it will also affect the beauty of the bridge

Embodiment Construction

[0009] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0010] Such as figure 1 As shown, the vehicle projection system provided by the embodiment of the present invention includes a camera device 10 , a projection device 20 , an image processor 30 , a power supply device 40 and a projection screen 50 .

[0011] The camera device 10 is fixed on the car shell 60 for monitoring the external conditions of the car. The camera 10 adopts a fisheye lens, and the fisheye lens is a super wide-angle lens, which can increase the range of captured images. In this embodiment, the camera device 10 is fixed at the rear end of the vehicle body, and is used to collect the situation behind the vehicle body when the vehicle is reversing. It can be understood that in order to enable the camera device 10 to capture a wider range of images, the camera device 10 can be arranged on an angle-adjustable seat 11; in order to protect the l...

Abstract

The invention relates to a projection system for a car, which comprises a pick-up device, a projection device, an image processor, a power supply device and a projection screen, wherein the pick-up device is fixedly arranged on the outer housing of the car, the projection device is hung at the top end of the inner housing of the car, the image processor and the power supply device are located inside the car, the pick-up device is electrically connected with the projection device through the image processor, and the power supply device respectively supplies power for the pick-up device, the projection device and the image processor. The projection screen located on a windscreen of the car comprises a projection area selected from the windscreen and at least one layer of reflection film attached to the surface of the projection area, and can fully reflect light projected by the projection device. By attaching the reflection film on the projection area of the windscreen of the car to formthe projection screen and locate the projection screen on the windscreen, the projection system occupies less space of a driving coach.

Description

technical field [0001] The invention relates to a projection technology, in particular to a vehicle projection system. Background technique [0002] With the development of science and technology and the continuous improvement of people's lives, cars have entered the lives of many people, and safe driving of cars has become an issue that people are more and more concerned about. [0003] At present, in order to improve the safety of driving a car, a car projection device is usually mounted on the car, and the car projection device transmits the situation around the car to the projection device suspended in the car through the imaging device, and the projection device The external image collected by the imaging device will be imaged on the projection screen located on the driver's platform. However, installing the projection screen on the driver's platform of the car will not only occupy a large space on the driver's platform and affect the quality of other equipment. Instal...
