In recent years, due to the rapid increase in the number of cars and the complicated and changeable road conditions, traffic accidents have always occurred. Among them, traffic accidents caused by blind spots and blind spots have also occurred frequently. Not long ago, CCTV reported that there were many children ’s traffic accidents in Jiangxi, Zhejiang and other places during the summer vacation this year. The reason was that the driver could not see the children in front of the right side of the vehicle when turning right. The sight glass simply cannot help the driver to fully observe the front right of the vehicle, especially the blind area under 1 meter that children may enter. "People are paying more and more attention to car safety performance. How to help drivers completely eliminate dead spots and blind spots in the driving process, reduce or even completely avoid the accidents that have occurred is already a hot research project of automotive electronics industry." Fujitsu Wang Yun, a senior manager of the semiconductor market department, expressed his views at the 2013 China (International) Automotive Electronics Forum held in Beijing a few days ago, "However, even if some mid-to-high-end models have been installed with panoramic driving assistance systems, 9 Most of them are 2D imaging technologies, which still have relatively large limitations. They can only be used as reversing images, and cannot give drivers a comprehensive and clear judgment while driving. " Figure 1: Wang Yun, Senior Manager of Fujitsu Semiconductor Marketing Department, gave a speech at the 2013 China (International) Automotive Electronics Forum. Wang Yun especially introduced to the audience how Fujitsu Semiconductor ’s global 360 ° panoramic 3D driving assistance system OmniView technology helps drivers eliminate blind spots and effectively respond to the challenge of driving safety, and introduced Fujitsu Semiconductor ’s mass production and the latest generation of The 3D graphics SoC platform solution has aroused heated discussion in the industry that 3D panoramic imaging technology is expected to accelerate its application to advanced driver assistance systems (ADAS). The world's first 360 ° panoramic 3D video imaging system Fujitsu ’s OmniView 360 ° panoramic driving assistance system can be regarded as the world ’s first true driving assistance technology for realizing 3D panoramic imaging. It is based on Fujitsu ’s years of technology accumulation in the imaging field, through sophisticated software algorithms and powerful hardware platforms , Achieve 360 ​​° full-angle seamless display of the surrounding scenes of the car body, which can help the driver to easily grasp the large-scale scenes outside the car body visually and effectively guarantee the driving safety. Figure 2: Fujitsu OmniView 360 ° panoramic driving assistance system supports free change of perspective Wang Yun said that the OmniView system synthesizes the images captured by four or even six directions of cameras mounted on the vehicle on the three-dimensional model to enable the driver to grasp the scene outside the body. At the same time, the system supports freely changing the angle of view to ensure the driver Have an appropriate angle to observe the field of view suitable for the driving scene, and promptly find people and objects around the body, including, so as to avoid traffic accidents caused by the driver's blind spot as much as possible. Figure 3: Comparison of traditional 2D imaging and Fujitsu 3D video imaging technology. Traditional 2D imaging technology, because the camera image is projected on the two-dimensional plane of the traditional system, can only display the top-down image from above, sometimes it is difficult to determine the nearby vehicles and pedestrians; especially the portrait, because of the angle of the top view, The portrait is presented as a flat image with dots and shadows (as shown in the left of Figure 3), which makes it difficult for the driver to distinguish and increases the danger during driving. In contrast, Fujitsu ’s OmniView 3D imaging technology projects images on a three-dimensional curved surface, making it easier to recognize by using close-up images that freely change the angle of view and desired parts. Through multiple cameras installed on the front, back, left, and right sides of the vehicle body, and high-definition image processing functions, the Fujitsu OmniView system can display the vehicles and pedestrians around the vehicle body in a 3D stereoscopic image. The position of the person on the back left. Figure 4: Fujitsu's unique "bowl-shaped" panoramic image stitching technology. The Fujitsu OmniView 360 ° panoramic 3D video imaging system uses cameras facing front, back, left, and right to capture the surrounding images, and uses the image stitching technology to synthesize the 3D model of the environment to form a "bowl-shaped" panoramic image as shown in FIG. 4 and display it from any angle. The surrounding conditions of the car body enable the driver to obtain various information around the car body in an intuitive way to improve driving safety. Wang Yun also emphasized that Fujitsu has made a comprehensive and in-depth optimization of the OS operating interface of the driving assistance system. The system startup speed is less than 3 seconds, and the delay in image acquisition and display is only 30ms, which can almost achieve the image and body on the display. Synchronized outside the actual environment. The common Win CE or Android operation interface on the market is slow to start, which cannot meet the real-time display and high-speed startup required for driving safety. The OS operation interface of the OmniView system is more user-friendly and more suitable for driving safety systems.
