Problems solved by technology

[0004] However, the current 360-degree panoramic surround view imaging system still has the disadvantage of being unable to perceive the blind spots under the vehicle
In recent years, there have been more and more news reports that some unskilled drivers, when the car is parked or parked, are unaware of the small children being involved in the bottom of the car, causing tragic traffic accidents

Embodiment Construction

[0040] Such as figure 1 with figure 2 As shown, the present invention discloses a method for transparent bottom of a vehicle based on nonlinear optimization, which includes the following steps:

[0041] Step 1. Obtain the top view of the current frame including the blind area under the vehicle, and obtain the processed top view of the previous nth frame.

[0042] In this embodiment, the 360° panoramic view image system of the vehicle is used to generate a panoramic view top view. Specifically, the video streams acquired by the multiple cameras installed around the vehicle are input to the vehicle-mounted 360° panoramic surround-view imaging system for preprocessing to generate a panoramic surround-view top view including the blind spots under the vehicle.

[0043] Step 2. Acquire the body pose information, and then use the body pose information to calculate the relative pose information between the previous nth frame and the current frame, where n≥1.

[0044] When obtainin...

Abstract

The invention relates to a non-linear optimization-based underbody transparency method, device and equipment, a storage medium and a computer program product, and the method comprises the steps of constructing an optimization function through the feature points of the top views of a current frame and a previous nth frame, introducing the relative pose information of an automobile body, and carrying out the non-linear optimization, thereby obtaining the relative motion information between the current frame and the previous nth frame; and then obtaining a transformation matrix according to the relative motion information, and finally performing mapping between the previous nth frame and the current frame by using the transformation matrix, and performing blind area filling of the top view of the current frame. According to the method, the transparent automobile body effect can be improved by introducing nonlinear optimization, the matching efficiency and reliability can be improved by combining the image with the automobile body motion information, optimization convergence is accelerated, and the vehicle bottom transparency effect is further improved.

Description

technical field [0001] The present invention relates to the technical field of vehicle assisted driving, in particular to a method, device, system, storage medium and computer program product based on non-linear optimization for vehicle bottom transparency. Background technique [0002] In recent years, cars have played an increasingly important role in people's daily work and life. However, car driving operations need to be mastered through specialized technical training, and driving a car on a complex road environment requires the driver not only to have skilled driving skills but also to have a high degree of concentration, which not only reduces the safety of car driving , also raised the threshold for car driving. [0003] In the process of lowering the threshold of car driving and improving safety and comfort in the automotive industry, the on-board electronic system gradually develops the Advanced Driver Assistance System (ADAS), which introduces imaging technology, ...
