What is a car front camera
The front camera of a car usually refers to the on-board imaging device installed at the front of the vehicle. Its main functions include parking assistance, obstacle recognition and environmental monitoring. It is a core component of advanced driver assistance systems (ADAS).
Core function
Youdaoplaceholder0 Parking assistance : Displays non-mirror images on the digital display screen and supports reversing scale line assistance function.
Youdaoplaceholder0 Obstacle recognition : Detect obstacles such as vehicles and pedestrians ahead to avoid collision risks.
Youdaoplaceholder0 Environmental perception : Some models adopt multi-camera collaboration to achieve 360° environmental monitoring, enhancing driving safety.
Hardware composition
It usually includes components such as optical lenses, image sensors, and image signal processors, and is classified into types such as front-view, surround-view, and rear-view according to their installation positions.
Technological development trends
8-megapixel cameras have become mainstream, capable of detecting longer distances and smaller targets, but they require higher computing power and thermal management technology support.
The forward-looking camera is an on-board imaging device installed at the front of a vehicle, mainly used in parking assistance scenarios and obstacle recognition. This device achieves non-mirror original image display through a digital display screen and supports the auxiliary function of reversing scale lines. Tesla and other automakers will integrate it into the front bumper position by 2025, using South Korean PC1030 series chips and SONY CCD sensors, and equipped with all-glass lenses to enhance image clarity.
The core functions include front obstacle recognition (with an accuracy rate of 97%), 150° wide-angle coverage of traditional blind spots, and LED supplementary lighting to enhance the night imaging effect. The installation location covers areas such as the front license plate frame and the bottom of the rearview mirror. Its environmental adaptability ranges from -20℃ low temperature to strong light conditions. The imaging quality is affected by the chip architecture, lens debugging process and display screen type.
It can be installed under the front license plate frame or fixed on the license plate frame with two screws on the license plate. Some can also be installed on the right side of the front of the vehicle, so that the blind spot on the right can be seen. Others can be installed under the left and right rearview mirrors, so that the blind spot ahead can be seen. Generally, the front view camera installed in the middle can be made with a reversing scale reference line. Front-view cameras installed elsewhere do not need to have a reversing scale reference line.
Under normal circumstances, the clarity of a forward-looking camera is related to the following factors:
What kind of chip does the camera use
The better the chip, the better the clarity; conversely, the side is worse. The main chips used in front-view cameras include PC1030, PC3030, PC6030, PC6070 and high-definition 1089 from South Korea, as well as high-definition SONY CCD chips, BF3003 from BYD, MT9V136 from Micron, and OV7950, 7959, 7960 from the United States. Another point is that for Sharp CCD and SONYCCD, the better the chip, the better the imaging effect at night. If infrared supplementary lighting and LED white light supplementary lighting are added, the night effect will be even more outstanding.
It is different from the material used for the lens and the size of the Angle
Under the same size and Angle, the imaging effect of a full glass lens is much better than that of a glass-plastic hybrid lens. The larger the Angle, the wider the visible field, but the distant areas appear smaller and blurry. A lens with a small Angle has a clear distant area but a narrow visible range.
Lens adjustment
The operator's debugging level also affects the image clarity of the forward-looking camera
It's related to the display screen.
Clarity is also related to the type of display used. As there are analog screens and digital screens, the display effects of each manufacturer's screens will be different. The same front-view camera will display much clearer on a digital screen than on an analog screen.
The common causes of faults in the front camera of a vehicle include stains on the camera, equipment failure, software anomalies or wiring problems. These issues can be resolved through cleaning, system reset, software upgrade or professional inspection.
Youdaoplaceholder0 Cause and solution of fault
Youdaoplaceholder0 stains on the surface of the camera .
Dust, sand or foreign objects adhering to it can cause abnormal image acquisition and trigger system alarms. The surface of the camera can be cleaned with a soft cloth to ensure a clear view.
Youdaoplaceholder0 software system anomaly .
Triggering active braking, system algorithm bugs or version compatibility issues may cause false alarm faults. The solutions include:
Restart the vehicle's power supply or in-vehicle system;
Contact the 4S store to upgrade the in-car system or wait for the manufacturer's OTA push update.
Youdaoplaceholder0 hardware or line failure .
If cleaning and software repair are ineffective, the following hardware issues need to be investigated
Check if the camera connection cable is loose or damaged, and then reinsert or replace the cable.
The camera itself is damaged and the signal data needs to be detected by professional equipment and the components replaced.
If the camera is not calibrated after the windshield is replaced (such as in the Lynk & Co 01 model), a dedicated device needs to be used for road test calibration.
Youdaoplaceholder0 Warranty and professional repair
Youdaoplaceholder0 Warranty policy .
Original factory cameras usually come with a 1-3 year warranty. If they are not damaged by human factors, they can be replaced for free (purchase vouchers are required).
Youdaoplaceholder0 in-store testing process .
It is recommended to make an appointment with the 4S store first. Technicians will use a diagnostic instrument to read the fault code and repair the hardware or upgrade the software in a targeted manner.
Youdaoplaceholder0 Prevention and maintenance advice
Regularly clean the front camera and the surrounding sensor area;
Avoid frequent sudden braking triggering system misjudgment;
Pay attention to the system update notifications released by car manufacturers and upgrade in a timely manner.
