Truck circumnavigation system monitoring scheme

Truck circumnavigation system monitoring scheme

Installation model: 4 wheel truck



Problems encountered during the driving of the truck
Trucks usually need to transport large, relatively heavy goods, so during the process of driving, the braking distance of the truck is much longer than that of the car。The longer the braking distance, the more difficult it is for the driver to stop safely。One of the reasons why the front of many large trucks is very large and high is to allow the driver to obtain a wider range of forward vision and help the safe braking。
However, the head of the truck is not the bigger the better, the higher the head, it will also bring more and more visual blind areas。
The main visual blind areas of today's trucks include:

1.The blind spot between the headlights and the ground

2.Lateral blind area within 2-3 meters of the left and right front wheels



3.Container tail 3A blind spot within a meter


Preliminary scheme
By installing a camera in the front of the truck, on both sides of the car and at the rear of the truck, and connecting to the on-board display in front of the driver's seat, the driver can monitor the picture covering the blind area at any time during the driving process。

Option 1:4-way monitoring, the driver can see 4 blind areas in the display screen。
Option 2:360-degree panoramic image system, the driver in the display screen, with God's perspective to observe the truck and the surrounding situation, compared to the 4-way monitoring is more intuitive。

The final choice was to install a 360-degree panoramic video system on the truck。



 
Detailed scheme
1. Product composition
The whole set of products includes: 360 panoramic image host 1, 360 degree panoramic image dedicated camera 4, car 9 inch display 1, wiring several。


Second, system composition
The 360-degree panoramic image system consists of video recording system, processing system and display system。
Among them, the video system includes four dedicated cameras for 360-degree panoramic images;The processing system includes a 360 panoramic image host;The display system consists of a display screen and a memory card。


Third, installation position

Video system: 4 special cameras are installed in the front of the net, the left side of the top of the cargo box, the right side, the rear edge, to achieve 360-degree full coverage of the surrounding environment of the car。

Processing system: 360 panoramic image host can generally be installed near the driver's dashboard, combined with the actual situation of the cargo box, can be hidden installation。






Display system: The 9-inch display is installed next to the operating panel in the driving position, and the memory card is installed behind the display。

Iv. Function
① Blind area coverage function。Each special camera uses a super wide-angle fisheye lens, and four cameras can form 360-degree panoramic images, basically covering the main blind areas around the truck。

② Automatic trigger function。During the normal forward process, the driver generally does not watch, and there is no need to trigger the function of 360-degree panoramic images at this time。When reversing and turning, the blind area around the truck will affect the driver's judgment, and the 360 panoramic function will be automatically triggered to assist the driver。

③ View switch function。Most of the 360-degree panoramic images on the market only have a bird's eye view, but the 360 panoramic image dedicated to this truck can switch different perspectives。In China, the driving position is on the left side, so the main blind spot of Chinese trucks is on the right side。And this truck 360 panoramic image can show the right side of the truck blind Angle of view, very humanized。


5. Practical effects
① Sense potential danger。With the truck as the center, the picture within 3 meters can be clearly seen by the driver in the display of the driving position, and then the driver can slow down, brake and other reactions in advance to avoid traffic accidents。
② It is more convenient to reverse。When reversing, a screen can see the environment around the front and back of the truck, and there is no need to turn around to see the blind area。


Customer feedback
Generally, you will choose to watch 360-degree panoramic images when reversing, because the picture at this time covers a wider range than the reversing image。And the original reversing image is standard definition, while this 360-degree panoramic image can reach 1080P, and the details of the surrounding environment are much clearer。
