Title:
A-PILLAR IMAGING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/061999
Kind Code:
A1
Abstract:
An A-pillar imaging method, which belongs to the technical field of driving images. The method is implemented on the basis of an A-pillar imaging system, and comprises: step S01, calculating, in a vehicle coordinate system, the coordinates of the position of the head of a driver on the basis of an in-vehicle image collected by a glabella monitoring camera, wherein the glabella monitoring camera is arranged on a steering column of a steering wheel of a vehicle; step S02, tracking the eyes of the driver by means of the glabella monitoring camera, calculating the three-dimensional coordinates of the glabella of the driver in a world coordinate system, and obtaining the trajectory of the line of sight of the driver; step S03, on the basis of vehicle front images collected by two A-pillar cameras, constructing, by using a three-dimensional reconstruction algorithm, three-dimensional image information that includes an A-pillar blind area obstacle; and step S04, projecting the three-dimensional image information in step S03 onto the normal plane in which the line of sight, as in step S02, of the driver is, so as to obtain an image which is the same as the imaging of the human eyes, and displaying the image on an A-pillar flexible display screen. By means of the method, the effect of a transparent A-pillar can be realized, and a display picture is dynamically adjusted according to the line of sight of human eyes, thereby ensuring that picture display conforms to human eye vision.
