Manual calibration correction method

Dear customer. Let's talk about automatic calibration

Place the calibration cloth and calibration notices

First, enter the settings and find the version option

Click on the version option for five times

Click calibration

Select the corresponding calibration cloth

This tutorial uses two large pieces of cloth

Select large cloth for automatic calibration

Click to enter

You can see front, rear, left and right camera images

It cannot be placed randomly

Random placement will directly lead to calibration failure. Or the effect is not well

Let's talk about the way of placing calibration cloth

The front calibration cloth must be parallel to the front of the vehicle

It's best to take a tape measure

The distance from the left and right tires to the calibration cloth must be the same

Align the middle of the calibration cloth with the middle of the vehicle logo

In this way, it can be ensured that the calibration cloth and the front of the vehicle are centered and parallel

The rear calibration cloth is placed the same as the front calibration cloth

The rear calibration cloth must be parallel to the rear of the vehicle

It's best to take a tape measure

The vehicle length is the distance between the front and rear calibration cloth edges

The vehicle width is the actual vehicle width plus 20 cm

Or use a ruler to measure the distance between the left and right tires then plus 20 cm

The front and rear cameras must be able to see the whole calibration cloth

The closer the edges of the calibration cloth to the front and rear bumpers?the smaller the blind area will be.

The left and right cameras must be able to see the black squares at the front and rear cloth

When installing the left and right cameras, rotate the camera

Try to keep the front and rear of vehicle in the left and right pictures on a horizontal line.

Make sure the calibration cloth is placed correctly and click next step

Click car param

Enter vehicle length and width

Select sensitive chip type and lens type

These parameters must be entered correctly

Otherwise, the effect will not be achieved

 

 

Wheelbase, front wheelbase and rear suspension are related to track accuracy

You can use default values

If you need more accurate

Please enter accurate parameters after measurement

The height of front, rear, left and right cameras is related to the 3 D elevation

If there is no image area on the elevation

Accurate input of parameters

It can effectively improve the 3D elevation display effect

The distance of mirror to the front of vehicle

The distance of the rear of vehicle to rear calibration cloth

The distance of the front of vehicle to calibration cloth

These parameters are related to the inclination of the elevation image

You can use default values

Higher requirements can measure and input accurate parameters

After parameter input

Click calibration

Wait a few seconds

The system displays that the automatic calibration has been completed. Do you want to exit

Click OK to return to the main interface to see the calibration effect

You can also click Cancel to enter manual calibration - draw 8 dots in each camera's view.

See splicing effect

If the left view screen is bent

Click Advanced adjustment to enter the center point adjustment

Click left view or press the number 0 on the remote control to switch to left view

Select longitudinal adjustment

Press the up and down buttons on the remote control to add and subtract values

We can turn the value up first

While adjusting, see if the left line becomes straight

If the bending is more serious

You can reduce the value in the opposite direction

Until the left-hand landmark becomes straight

The vertical direction is generally about 365

If the right view screen is bent

Click right or press the number 0 on the remote control

Switch to right view

Select longitudinal adjustment

Press the up and down buttons on the remote control to add and subtract values

We can turn the vertical up first

While adjusting, see if the right line becomes straight

If the bending is more serious

The vertical can be reduced in the opposite direction

Until the right-hand landmark becomes straight

The longitudinal value is generally about 365

If the left and right ground markings are not in the same horizontal position

We can adjust the left and right cameras

The horizontal adjustment of picture

Adjust the longitudinal direction

To adjust the horizontal picture

If the ground marking line is staggered, there is no need to rearrange the calibration

You can fine tune it in the following way

Click Advanced

Click forward view

Or press the number 0 on the remote control to switch to the front view

Let's adjust the staggered seam at the front left first

Now the left front marking is staggered to the left

We will move to the right and connect the staggered seam with the left ground marking

Turn right again and straighten the landmark

In the same way, let's adjust the staggered sewing of the lower right front

The right front is staggered to the right

We move the wrong seam to the left

Connect the staggered joint with the right ground marking

Then adjust the left rotation to straighten the landmark

After adjusting the front view, click the rear view

Remote control digital 0 switch to rear view

Let's adjust the left back staggered seam first

Now the left rear landmark is offset to the left

We will move to the right to connect the staggered seam with the left ground marking

Turn right again, and then align the landmark

In the same way, let's adjust the staggered sewing of the lower left rear

The left back is staggered to the right

We move the wrong seam to the left

Connect the staggered joint with the right ground marking

Then adjust the left rotation to straighten the landmark

Until it is adjusted to the best position

Click save

Then return to the main interface

The calibration is complete

 

Finally, let's see the effect
