Embodiment Construction
[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0037] The present invention provides a method for calibrating a simulated bench camera to solve the problem that the real-time machine cannot provide an accurate test scene for the FAS system due to the parameter difference and spatial relative relationship between the virtual camera and the real camera in the prior art. data problem.
[0038] Specifically, the method for calibrating the camera of the simulated bench is applied to a real-time machine for perf...

The application provides a method for calibrating a simulated bench camera and a real-time machine. The virtual camera is used to collect and image the added calibration reference objects, and to establish the first correspondence between any point and the coordinates of the virtual camera image plane; the real camera Collect the imaging, establish a second correspondence between the imaging point of any point of the calibration reference object in the imaging of the virtual camera and the real camera image plane coordinates; solve the two correspondences to obtain the calibration reference object The third corresponding relationship between the arbitrary point and the real camera image plane coordinates is output to the FAS system, so that the FAS system can obtain the corresponding relationship between the real camera image plane coordinates and the test scene data provided by the real-time machine, eliminating the virtual camera The parameter difference and spatial relative relationship between real cameras solves the problem that the real-time camera cannot provide accurate test scene data for the FAS system.
Description
technical field [0001] The invention relates to the technical field of automation, in particular to a simulation platform camera calibration method and a real-time machine. Background technique [0002] In recent years, with the rapid development and maturity of machine vision imaging and image processing technology, driver assistance systems based on monocular vision have been increasingly used in high-end vehicles. One of the important systems is the Fronview Assistance System (FAS), which includes multiple functions such as adaptive cruise control and automatic emergency braking. During the system development period, it is usually necessary to verify and test the functional logic and performance of the FAS system on a simulation bench. [0003] Therefore, it is necessary to use a virtual camera that provides a camera perspective to simulate scenes such as people, cars, and roads on the real-time machine, so as to provide test objects for product debugging. The real came...
