Description

A car driving imaging technology

technical field

The invention relates to a vehicle-mounted image technology, specifically relates to a technology that enables a driver to see front, rear, left and right omnidirectional images when a car is running or reversing, and belongs to the field of vehicle-mounted image technology.

Background technique

Vehicle imaging technology is mainly used in panoramic parking systems and reversing imaging systems. These products use a camera with a wide viewing angle to display the image on a display, and the display can also be switched to any camera to observe partial images. But the image from such a wide-angle camera will be distorted, and the image displayed on a monitor will be too small to be seen clearly. Moreover, these images are all images of the ground around the vehicle, which only serve as a parking assistance function, and have no effect on normal driving. Experienced drivers can use them, and they are not necessary for driving.

The rearview mirror is an imaging device that must be used during normal driving. However, the angle of view of the rearview mirror is very small, and you can only see the distant vehicles on the side and rear, but you can't see the vehicles that are very close, and scratching accidents are prone to occur when merging. When reversing, the driver must adjust the angle of the exterior rearview mirror to see the rear wheels, or see the rear wheels with the help of the auxiliary small round mirror pasted on the exterior rearview mirror, so that the car can be reliably reversed. The rearview mirror has a certain cross-sectional area, which will cause certain air resistance during driving, which is also one of the sources of noise. In addition, in rainy or cold weather, water droplets and fog attached to the window glass will hinder the viewing of the rearview mirror.

Contents of the invention

The purpose of the present invention is to design a set of driving imaging system using a camera, so that the driver can see the full range of images of the front, rear, left and right of the vehicle when driving the vehicle, not only the ground, but also distant images. It can replace the traditional rearview mirror.

The specific realization scheme of the present invention is like this: it is made up of 6 cameras, 3 displays and 1 switch.

A camera is installed at the front and rear of the car, i.e. a front-view camera and a rear-view camera, to observe the images directly ahead and directly behind. The installation of the camera should ensure that both the ground and distant images can be seen.

Two cameras are respectively installed on each side of the side of the vehicle body, one forward and one backward, i.e. a left front-view camera, a left rear-view camera, a right front-view camera and a right rear-view camera. The installation of the left front-view camera and the right front-view camera must ensure that you can not only see the distant images ahead, but also the front wheels and the ground; the installation of the left rear-view camera and the right rear-view camera must ensure that you can see the far In addition to being able to see the rear wheels and the ground.

The monitor is required to be connected to two cameras, and each of the three monitors is connected to two cameras, that is, one monitor is connected to the front-view camera and the rear-view camera; one monitor is connected to the left front-view camera and the left rear-view camera; one monitor is connected to the right front-view camera and right rear view camera.

The toggle switch has two positions of "front" and "rear", which are used to switch the display directions of the three monitors, that is, when the toggle switch is set to the "front" position, the three monitors display the left front-view camera and the front-view camera respectively. and the images of the right front-view camera; when the toggle switch is placed in the "rear" position, the three displays display the images of the left rear-view camera, the front rear-view camera and the right rear-view camera respectively.

The beneficial effects of the present invention are:

When driving normally, set the switch to the "rear" position. When the vehicle is moving forward or merging left and right, the driver can conveniently see the left rear image, the front rear image and the right rear image through three monitors, instead of Instead of the traditional rearview mirror, there is no need to turn the head or leave the front line of sight, which enhances driving safety;

When reversing, put the switch in the "rear" position, and the driver can easily see the left rear wheel and the ground, the right rear wheel and the ground, and the ground directly behind through the three monitors, so that the car can be reversed reliably.

When meeting vehicles, passing narrow roads and complex road conditions or passing obstacles, the switch can be placed in the "front" position, and the driver can easily see the left front image, the front right image and the right front image through the three monitors. It can also see the front wheels and the ground, as well as the road ahead blocked by the front of the car, and can accurately judge the left and right distances between the car and the opposite vehicle, the edge of the road or obstacles to ensure driving safety.

The invention uses a camera to observe images around the vehicle, replacing the traditional rearview mirror, and will not be affected by water droplets and fog attached to the window glass in rainy or cold weather, and can ensure driving safety in rainy or cold weather.
