Embodiment Construction
[0045] In order to have a further cognition and understanding of the features, purpose and functions of the present invention, the relevant detailed structure and design concept of the device of the present invention will be described below, so that the characteristics of the present invention can be understood. The detailed description is as follows :
[0046] see figure 1 As shown, this figure is a schematic flow chart of an embodiment of the method for seamless joining of full-circumference bird's-eye view images according to the present invention. The method first provides a plurality of environmental images in step 20 . The environment image may be a surrounding environment image about a vehicle. The vehicle may be a movable mobile vehicle, such as a vehicle. To generate the multiple environmental images, a plurality of image capture units can be respectively arranged on different positions of the carrier, for example: charged coupled device (CCD) or complementary meta...

The invention provides an all-round aerial view image seamless junction method and an all-round aerial view image seamless junction system. A plurality of environment images related to a vehicle, which are acquired by different image acquisition units, are combined to form a seamless aerial view image, wherein the plurality of environment images are transformed to form corresponding aerial view images. The method comprises the following steps of: in the process of combining the plurality of aerial view images, finding out an overlap region between adjacent aerial view images and calculating a margin distance between a characteristic point and the overlap region according to characteristic point information positions of the adjacent aerial view images in the overlap region; and determining weight of image contribution of the adjacent aerial view images to the overlap region respectively so as to form an overlap image. After the overlap image between the adjacent aerial view images is determined, a seamless all-round aerial view image can be formed.
Description
technical field [0001] The invention relates to an image processing technology, in particular to a method and system for seamless joining of full-circle bird's-eye view images. Background technique [0002] Image-assisted driving technology has been around for a long time. However, most of the existing image-assisted driving technologies capture images and directly display them to users. Although there are merits, as the number of image capture units increases, displaying multiple images on one display is a visual burden for the driver. Therefore, the bird's-eye view image reconstruction technology came into being. In the design of advanced safety vehicles, the use of cameras installed around the vehicle to develop an image-based all-round bird's-eye view assisted driving system has been the main research and development technology of various car manufacturers and vehicle system manufacturers in recent years. Through image conversion and processing, the images captured by ...
