A multi-sensor based target detection and fusion device and method

Abstract

The invention relates to a multi-sensor-based target detection fusion device and method. The fusion device comprises at least two sensor units, a vehicle-mounted driving auxiliary domain controller, a display screen and a power source. Each sensor unit comprises a sensor and an electronic controller connected with the sensor, wherein the electronic controller is connected with the vehicle-mounted driving auxiliary domain controller to form a distributed structure. The vehicle-mounted driving auxiliary domain controller is connected with the display screen. The power source is connected with the sensor unit, the vehicle-mounted driving auxiliary domain controller and the display screen separately. The method comprises the steps of determining target pairs, wherein the target pairs with the closest distance are obtained, and the target pairs may be the same target found by different sensors; determining whether the target pairs are the same or not. Compared with the prior art, the multi-sensor-based target detection fusion device has the advantages that more attributes of the targets are obtained, the framework is simple, and expandability is achieved.

Description

technical field [0001] The present invention relates to the field of advanced driving assistance technology, in particular to a multi-sensor-based target detection and fusion device and method, which is especially suitable for the fusion and differentiation of targets and target attributes identified by vehicle-mounted radar and vehicle-mounted machine vision . Background technique [0002] The Advanced Driver Assistant System (ADAS for short) uses various sensors installed on the vehicle to collect environmental data inside and outside the vehicle in the first place to identify and detect static and dynamic objects. Active safety technology that enables the driver to detect possible dangers in the fastest time to attract attention and improve safety through technical processing such as tracking and tracking. The sensors used in driving assistance systems mainly include cameras, millimeter-wave radars, lidars, and ultrasonic radars. [0003] Each sensor has its own scope o...
