AVM 360° Camera Calibration System Definition

Through four ultra-wide-angle cameras installed at the front, rear, left, and right of the vehicle body, images around the vehicle are simultaneously captured. After "real-time image distortion correction and stitching technology" processes the images through distortion correction, perspective transformation, image stitching, and image enhancement, a seamless and complete panoramic bird's-eye view of the vehicle surroundings is ultimately formed.

This system can not only display the panoramic view, but also simultaneously display a single view in any direction; drivers can accurately read the position and distance of obstacles with the assistance of scale lines.

AVM 360° Camera Calibration System Functions

1. In cities today, parking environments are becoming increasingly complex. To park quickly and avoid scratches, this panoramic image system that covers 360 degrees around the vehicle is a capable assistant.

When you need to pass through alleys in old city areas or on narrow roads, if you cannot accurately control the safe range for the vehicle to pass, just turn on the AVM panoramic monitoring image system, and the system will read data from the electric power steering and cameras to provide the driver with the vehicle's forward driving trajectory, with position assist lines to help the driver judge distances.

2. Besides helping drivers successfully pass through narrow sections, the AVM panoramic monitoring image system can also help drivers, especially novice drivers, solve parking problems.

When parking by the roadside, if you're not careful, the tires may rub against the curb. Scratching the tires is a minor issue, but causing a flat tire is troublesome. With the AVM system, drivers can easily gauge the distance between front and rear objects, parking spaces, and the vehicle. Even curbs that are hard to see can be clearly viewed on the display screen showing the distance between the vehicle and the curb, making parking effortless.

In addition, the AVM panoramic monitoring image system can also effectively avoid collisions with low obstacles. Since many low obstacles cannot be observed from the rearview mirror, and parking sensors also have difficulty sensing them, the advantages of the AVM panoramic monitoring image system become even more prominent. Simply turn on the monitoring image, and the vehicle's surroundings are clear at a glance. Avoiding obstacles is that simple.

AVM 360° Camera Calibration Process

1. The vehicle enters the test station and is aligned;

2. Scan VIN and vehicle model code;

3. Connect the OBD plug and perform AVM data reading;

4. After AVM data reading is completed, perform data calculation and calibrate the AVM simultaneously;

5. Notify the calibration board to return to position, simultaneously write AVM calibration data back to the ECU, and download the FLASH program;

6. MES monitors the results, locally saving logs and data;

7. Disconnect the diagnostic OBD plug and prepare for the next test;

After the test is completed, the operator disconnects the test terminal from the vehicle; meanwhile, the test report is sent to the product quality computer, and vehicles with fault codes will have reports printed. The operator attaches the test report to the vehicle data sheet.

Project Execution

Shanghai LeaderSoft Information Technology Co., Ltd. (LeaderSoft) will strictly follow the customer company's specifications and the strict standards for 360-degree calibration projects, providing customers with a turnkey solution and integration work for the 360-degree panoramic image calibration system.

To meet customers' panoramic image calibration requirements, LeaderSoft generally customizes professional calibration sites, calibration target boards, and vehicle alignment devices. Custom development is carried out in lighting, vehicle alignment devices, target board precision control, site reflection, vehicle calibration control, factory eCATS, and FIS communication to meet various customer requirements. By selecting appropriate light sources and appropriate heights and angles to produce non-uniform lighting, this ensures that light does not directly shine on the camera lens through mirror reflection if the on-site environment cannot meet the requirements.
