Description
Technical Field
The invention relates to the technical field of automobile testing, in particular to a testing system and a testing method for vehicle panoramic all-round vision testing.
Background
With the rapid development of economy in China, the quantity of automobiles kept by residents is increased year by year, and the adoption of automobile traveling becomes the normal state of office workers, so that the roads of various cities are frequently congested in early peak and late peak. When parking, in order to avoid accidents such as scraping and collision of a driver, the vehicle is basically provided with a panoramic function, and a 360-degree panoramic top view without gaps around the vehicle is formed on a display screen of the vehicle machine, so that the parking safety is improved.
In order to ensure the effectiveness of the panoramic function, the panoramic function needs to be tested before the vehicle leaves the factory. For example, there is a corresponding technology disclosed in the chinese patent, in which cameras are provided at the front, rear, left, and right of a vehicle to collect peripheral patterns of the vehicle, and a panoramic controller collects the peripheral patterns through the cameras and synthesizes a panoramic top view; when the vehicle slides on the sliding guide rail, the panoramic controller sends a panoramic message to the upper computer according to the synthesized panoramic top view, the upper computer obtains the synthesized panoramic top view according to the panoramic message, and the synthesized panoramic top view is compared with the preset pattern on the calibration cloth to determine the 360-degree panoramic function of the test trolley. Although the test efficiency during the production of the vehicle is improved and the development period of the whole vehicle is reduced, the prior art does not realize the problem of system delay, and the system delay of the vehicle panoramic looking-around system mainly comprises two parts: the method comprises the following steps that firstly, local delay is adopted, namely camera delay is adopted, namely the camera delay is the delay among cameras for collecting images, and the mutual delay among the cameras in the shooting process is realized; the second is "integral delay", which refers to the delay of the process of "shooting-splicing" and the delay of the process of "splicing-displaying". Therefore, in the above-described technical solution, although the 360-degree panoramic function of the test carriage can be determined, the delay performance of the panoramic looking-around function of the vehicle to be tested cannot be tested.
