    ✒ Lens: Gathers light and projects the scene onto the surface of the imaging medium. Some are single lenses, and some require multi-layer glass lenses for better imaging effects.✒ Filter: The scenery seen by the human eye is in the visible light band, and the light band that the image sensor can discern is larger than the human eye. Therefore, a color filter is added to filter out the excess light band, so that the image sensor can capture what many people see. actual scenery.✒ Circuit board substrate (PCB board): transmits the electrical signal of the image sensor to the back end. For vehicle cameras, the circuit substrate here will have more circuits. It is necessary to convert the parallel camera signals into serial transmission, so that the anti-interference ability is stronger Some.✒ The basic working principle is that the target object collects light through the lens, and then filters out the unnecessary infrared light through an IR filter. Finally, the generated optical image is projected onto the image sensor. The optical signal is converted into an electrical signal, and after passing through the A/D (analog-to-digital conversion), it becomes a digital image signal, and is finally sent to a DSP (digital signal processing sensor) for processing. The DSP processes the signal into an image in a specific format and transmits it to the display screen for display.✒ Generally speaking, the lens group and CIS (CMOS Image Sensor) will be packaged into a module. After becoming the lens module, it will be packaged with DSP and other image signal processing chips to form a complete camera system.The above is basically the structure of the car camera. In addition, you need to pay attention to the placement outside the car body, because to take into account the occurrence of various harsh external weather and other conditions, you need to form a complete camera. If it is in the car The built-in camera, such as a DVR, does not need to be waterproof and can be assembled into a camera module.  
  • What are the factors that affect imaging quality?
    What are the factors that affect imaging quality? Mar 20, 2024
    Why do images presented by a lens have optical aberrations?A. DistortionDistortion will cause real objects to be straight lines, but in photos to be non-straight lines, to be curved lines.a) barrelb) pincushionc) complex/wavyTypes of lenses prone to distortion: usually zoom lenses and wide-angle lenses.B. Field curvatureFor plane objects in reality, after imaging, the real image surface is curved, and most actual sensors are also flat, which will cause the center field of view and the edge field of view to be unable to present clear images at the same time.Lens types prone to field curvature: usually wide-angle lenses and large aperture lenses.C. Vignettinga) Vignetting-----Light FalloffUneven brightness Light Falloff, the exposure of the center field of view and the edge field of view are different, resulting in inconsistent brightness between the center and edge of the picture, which is what we often call the camera vignetting problem.b) Vignetting-----Color CastUsually there is a color difference between the edges of the picture (especially the corners) and the center area. It is not entirely caused by lens aberration, filters and sensors will also have a certain impact.Types of lenses prone to vignetting: usually largeThere are many factors that cause optical aberration in lenses, some of which have been shared above:1) distortion2) field curvature3) Vignetting ---Light Falloff4) Vignetting ---Color CastIn fact, there are some other influencing factors:1) Focus ShiftWhen you reduce the aperture size, the best focus plane will move to the front or back. That is, the aperture size will affect the best focus plane position, which is what we call focus shift.Common lenses that are prone to focus shift: large aperture lenses. When adjusting the aperture, the focus usually needs to be re-adjusted.2) Onion ring bokehThere are some out-of-focus circular rays of light in the optical path of the lens, which is generally caused by a defective lens.Common lenses that are prone to "onionrings": Some large aperture lenses often use aspherical lenses because of the flatness of the surface involved during processing.3) Flare-GhostingWhen there are some abnormal colored patches in the presented image, usually like colored circles or colored blocks of specific shapes, we become ghost images.Common ghost images: zoom lenses, lenses with a large number of lenses, and large-diameter lenses. During processing, try to reduce the aperture as much as possible, or use post-image processing.4) Flare-Internal ReflectionsGenerally speaking, highly reflective objects inside the lens, such as structural parts with too high reflectivity, or dirty lenses in the optical path, etc. In most cases it is caused by workmanship issues.Common internal reflection stray light lenses:especially large aperture lenses, during the production process, you can try to eliminate light, cut off light, block stray light, increase transmittance, and reduce the aperture as much as possible when conditions permit.

    How to protect driving safety with surround view monitors? Mar 19, 2024
    AVM is a panoramic image system, namely Automotive Around View Monitor/Surround View Camera.It is another great helper for safe driving and can realize driving without blind spots.Images are captured through multiple ultra-large wide-angle fisheye lenses, and then the captured images are distorted and spliced through data processing to form surrounding images.It is mostly used in automobile systems to provide the driver with a bird's-eye view of the surroundings of the car body, eliminate the driver's blind spots, and provide effective visual assistance when parking.In fact, surround view systems can be divided into monocular, binocular and multi-view systems.Among them, the monocular and binocular systems must establish a virtual coordinate system while the vehicle is moving to draw a panoramic image to guide parking. The multi-view system can directly guide parking.⁉ So how many cameras are needed for the entire operation process?✔ 360-degree panoramic camera, 360-degree panoramic imaging system, 360-degree panoramic parking system, 360-degree panoramic vision system, and 360-degree panoramic reversing system simultaneously collect images around the vehicle through 4 ultra-wide-angle cameras installed on the front, rear, left, and right of the vehicle.✔ Through Pujieli's proprietary "real-time image distortion restoration docking technology", the image is processed through distortion restoration, perspective conversion, image splicing, and image enhancement, and finally forms a seamless and complete panoramic bird's-eye view of the car's surroundings.✔ The system can not only display a panoramic view, but also display a single view in any direction at the same time; the driver can accurately read the location and distance of obstacles by matching the ruler lines.  
  • What is the technical principle of car mounted surround lenses?
    What is the technical principle of car mounted surround lenses? Mar 07, 2024
    The technical principles of car mounted surround lenses mainly include the following aspects:Lens design: Car surround photography typically uses multiple cameras, which are distributed around the vehicle to provide a more comprehensive view. The design of a lens needs to consider various factors, such as the focal length, aperture, angle of view, etc., in order to obtain high-quality images during the shooting process.Shooting method: The shooting method for car surround lenses includes two aspects: hardware and software. Hardware includes cameras, brackets, power supplies, etc. It is necessary to choose high-quality equipment to ensure the stability of shooting. In terms of software, post production requires professional image processing software to fuse and concatenate images captured by multiple cameras to form the final surround lens image.Post processing: After the shooting is completed, it is necessary to perform post processing on images from multiple cameras in order to fuse them into a complete image.
