Problems solved by technology

[0006] Similar to the above-mentioned existing technologies, there are only monitoring outside the vehicle or only monitoring inside the vehicle, small visual range, serious color difference in image stitching and fusion, blind spots in front of and behind the car, non-fusion of image stitching, straight lines in public overlapping areas, low definition, The operation is complicated, the equipment is expensive, etc., which has greatly reduced the safety of the driver during driving, and accidents such as collisions and scratches are prone to occur.

Embodiment 1

[0188] In this embodiment, 4 external fisheye cameras are used to realize the functions of the present invention.

[0189] figure 1 The 8 cameras of the 8 image acquisition modules are shown in the figure. The exterior of the vehicle takes 4 wide-angle fisheye cameras as an example. The interior cameras of the vehicle can be 4 or other numbers, and the number of cameras can be different according to different vehicles and requirements.

[0190] For different types of vehicles, the installation position of the 4-way fisheye camera is different. For sedan vehicles, the front camera is installed next to the front license plate, and the middle is the best. The rear camera is installed next to the rear license plate of the vehicle. The middle position is the best, and the fisheye cameras on the left and right sides are installed under the rearview mirror. For passenger cars and trucks, the front camera is installed in the upper middle of the front of the vehicle, the rear camera i...

Embodiment 2

[0193] In this embodiment, 6 external fisheye cameras are used to realize the functions of the present invention.

[0194] For longer trucks, buses, etc., sometimes the best panoramic image cannot be obtained by using only 4 external fisheye images. , two cameras on the left and right, the front camera is installed next to the license plate of the vehicle, the middle is the best, the rear camera is installed next to the rear license plate of the vehicle, the middle is the best, and the two cameras on the left are respectively installed on the vehicle The left side is close to the front and the left side is close to the rear, and the two cameras on the right are respectively installed on the right side of the vehicle near the front and the right side near the rear. The fisheye image synthesis process is the same as that in Embodiment 1.

Embodiment 3

[0196] The calibration module is used to correct the fisheye image and generate the fisheye image conversion table required in the panorama synthesis module. Due to the characteristics of the fisheye camera, the images captured by the fisheye camera are severely distorted. If the information of severely distorted fisheye images is to be used, these distorted images must be rectified. Traditional calibration methods have high calibration accuracy, but the calibration process is complex and requires high-precision structural information. Although self-calibration is flexible, convenient, and does not require a calibration block, it is not accurate enough and robust. We use the Zhang Zhengyou planar calibration method, a method between the traditional calibration method and the self-calibration method, which can avoid problems such as complicated operation, high requirements on equipment, and insufficient calibration accuracy.

Abstract

The present invention provides a vehicle-mounted video monitoring system and method using 360-degree panoramic view technology, which relates to the field of vehicle driving safety and vehicle-mounted video monitoring. The 360-degree panoramic view technology is used to eliminate blind spots of vehicles, improve driving safety, low cost, convenience and practicality. The purpose is to provide the driver with information such as the monitoring image inside the car and the panoramic image outside the car. The system includes a vehicle-mounted monitoring host, a remote client, a cloud server, an operation and maintenance treasure, and a display connected to a local host. Post-processing, panoramic image enhancement. The invention integrates a number of advanced image processing technologies, and is characterized by low requirements on the hardware environment, portability, and high performance.

Description

technical field [0001] The present invention relates to the field of vehicle driving safety and vehicle video monitoring, in particular, to a vehicle video monitoring system and method applying 360 panoramic view technology, and especially to a method of intuitively presenting information such as vehicle interior and vehicle exterior images to the driver , to eliminate vehicle blind spots, improve driving safety and usability, a vehicle-mounted video surveillance system that applies 360 panoramic view technology. Background technique [0002] In recent years, with the rapid development of image technology and computer vision, more technologies have been applied in the field of automotive electronics. Driving a car usually refers to the rearview mirrors on both sides of the car body and the interior rearview mirror. Safety, but it is far from enough to rely solely on this information when parking. Although the reversing radar can provide sound reminders of obstacles at the fr...
