In the report features of formation of radar images (RI) and optical images (OI) in the mobile test complex of radio vision systems (RVS) of the car are presented. The radio vision system of the car (CRVS) of the MMwavelength with frequency modulation is considered. Features of formation and processing of the radar-tracking image (RI) in CRVS are discussed, in particular: the sizes of the image, system of coordinates, primary and secondary processing of RI, requirements till speeds of transfer of figures, real time of processing, a subsystem of display of RI and synchronization. The structure of the mobile test complex of CRVS is described. This complex consists of: CRVS, a video-camera, the module of formation, record and display of RI and of optical images (OI), the module of control of a complex, the power supply unit. Features of formation and display OI are considered, in particular: the coordination of scale and a foreshortening of images, maintenance of time synchronization at display and records of OI, and questions of synchronous fusion of RI and OI also. Keywords: radio vision system of the car, the radar image, a mobile test complex, features of formation and fusion of radar and optical images.
INTRODUCTIONThe development of motor industry in the world constantly increases and the intensity and density of transport movement on road increase also. As a result quantity of road and transport incidents (road accident) increases. The reasons of road accident are various. So, according to American Agency NTHSA, besides malfunction of a vehicle, 68% of road accidents are connected with a carelessness and insufficient knowledge of the driver of a road situation. Thus, insufficient knowledge of the driver is in direct dependence on conditions of optical visibility such as: light exposure of road and a roadside, visibility of a marking and indexes, a degree of windscreens impurity, presence in air of a fog, a snow, a rain, a dust, a smoke and other preventing factors.In works [1,2] it is shown, that the core by the decision of an actual problem of increase traffic safety of vehicles in conditions of absence or the limited optical visibility is use on the car of the radio vision system (CRVS), working in millimetric (MM) wave lengths and not dependent from any weather conditions, a smoke, a dust, etc. CRVS is the small-sized, all-weather, information-measuring system representing new generation of panoramic radar stations (RS) of the forward review for modern vehicles. This system has not analogues in the world market.Several years ago by experts of MAI, the experimental sample of CRVS who is intended for formation RI of road conditions in front of the car has been developed and produced. The driver in conditions of absence of optical visibility can observe on the screen of the indicator in interior of the car of an obstacle, border of road, passing, counter, and also the vehicles parked at a roadside within the limits of working range in view of dynamics of movement of own car.
