Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 and fig. 3, in this embodiment, a high-definition panoramic system based on analog signal transmission includes a front panoramic camera 1, a rear panoramic camera 2, a left panoramic camera 3, a right panoramic camera 4, a panoramic controller 5, and a display module 6; all integrated first analog signal coding chip in camera 1, the panorama after camera 2, the panorama left side camera 3 and the panorama right side camera 4 before the panorama, integrated first analog signal decoding chip and the second analog signal coding chip in the panorama controller, integrated second analog signal decoding chip in the display module. The panoramic camera comprises a panoramic front camera 1, a panoramic rear camera 2, a panoramic left camera 3 and a panoramic right camera 4 which are respectively connected with a panoramic controller 5 through twisted-pair lines, and the panoramic controller 5 is connected with a display module through the twisted-pair lines.
In this embodiment, the panoramic controller 5 is further integrated with a CAN chip, and the panoramic controller 5 is connected with a CAN bus through the CAN chip, and the CAN bus is connected with a Gateway (GW) 7.
In this embodiment, camera 1 installs in front bumper department before the panorama, camera 2 installs in rear bumper or back door department behind the panorama, panorama left side camera 3 installs in left outer rear-view mirror, panorama right side camera 4 installs in right outer rear-view mirror.
The working principle of the embodiment is as follows: the panoramic front camera 1, the panoramic rear camera 2, the panoramic left camera 3 and the panoramic right camera 4 respectively compile collected video image signals in a visual field into transmittable high-definition analog signals through a first differential analog signal coding chip, the signals are low-frequency signals, the frequency is generally 10-150Hz, the low-frequency signals are more common in life and are easily influenced by electric appliances or environments of a vehicle body, and therefore the video signals are unstable, the video signals adopt a differential transmission mode with better anti-interference performance, and then the video signals are filtered and compensated, and the video is guaranteed to be free from interference. In addition, the low-frequency signal has low requirements on the wiring harness and the connector, the video transmission can be completed through the twisted pair, and the wiring harness switching can be completed by sharing the connector of the vehicle body. The analog video signals are transmitted to a panoramic controller 5, the analog video signals are decoded by a first analog signal decoding chip and then are reduced into editable video signals, the editable video signals are processed by software and algorithm in SOC (system on chip), vehicle body signals received through a CAN (controller area network) bus are simultaneously fused to complete splicing of the video signals of the four cameras, finally the video signals are compiled into transmittable digital signals through a second analog signal coding chip and transmitted to a display module 6 (a vehicle-mounted display or a vehicle-mounted display screen), and the display module 6 displays video images on the display module 6 after the video signals are decoded by a second analog signal decoding chip.
In this embodiment, a vehicle adopts the high-definition panoramic system based on analog signal transmission as described in this embodiment.
