Abstract

The invention relates to an object recognition system on the basis of the virtual reality, wherein, the object is stared by a driver. The invention comprises an eye tractor (1) and an automobile driving simulation system, wherein, the automobile driving simulation system comprises an automobile driving simulator (5), a display screen (2) and a simulation system computer (3), wherein an output terminal of the eye tractor (1) is connected with the simulation system computer (3) which comprises a driving simulation program module, a scene manager, a scene staring object positioning ray calculation module, an intersectant vision object calculation module, an intersectant vision object recognition module and a fixation point screen coordinate calculation module; the scene manager comprises world coordinates of each object in the scene and the category information. The object recognition system combines the virtual reality technique and identifies the types of staring objects on the basis of tracking and obtaining the fixation point coordinates of the driver; the test efficiency is high, the cost is low, and the statistic of the test result is easily realized, thereby contributing to the scientific research.

Description

technical field [0001] The invention relates to the technical field of road traffic transportation system safety, in particular to a driver's visual search behavior recognition system, especially a driver's gaze object recognition system. Background technique [0002] Drivers, vehicles, roads and traffic environment constitute a complex road traffic system. In the process of driving, the driver completes the operation of the vehicle by sensing the traffic information from the road and traffic environment, among which, the driver obtains more than 80% of the traffic information through vision. [0003] Road designers or traffic management departments transmit traffic information to drivers through road markings and roadside signs, but due to the interference of other factors (billboards, roadside landscapes, etc.), the driver's gaze point may be blocked by these interfering objects. Attract without noticing objects that should be. The deviation of this information transmiss...
