Embodiment

[0059] A vehicle-mounted ultrasonic radar and a vehicle-mounted surround view system fusion method, is characterized in that: comprising the following steps:

[0060] Step 1: Complete the system calibration through the offline joint calibration of the system,

[0061] Step 2, complete the visual output by means of auxiliary scene display level fusion,

[0062] Step 3, complete the output of the feasible region through the hierarchical fusion of the drivable region,

[0063] Step 4, complete target output through target detection level fusion.

[0064] This embodiment proposes a method for the fusion of vehicle-mounted ultrasonic radar and surround view system to improve the robustness and richness of low-speed scene-related system applications based on the observation values ​​of the two: auxiliary scene display level fusion: the ultrasonic radar system detection The result is fused with the display interface of the surround view system, adaptively updates the surround view ...

Abstract

The invention relates to an integration method of a vehicle-mounted ultrasonic radar and a vehicle-mounted all-round looking system. Shortcomings of the prior art are solved. The technical scheme is that the integration method of the vehicle-mounted ultrasonic radar and the vehicle-mounted all-round looking system comprises the following steps of 1, finishing system calibration by using a system offline combined calibration mode; 2, finishing visual output by using an assistant scene display level integration mode; 3, finishing free space output by using a free space level integration mode; and 4, finishing target output by using a target detection level integration mode.

Description

technical field [0001] This patent relates to the field of intelligent driving, in particular to a fusion method of a vehicle-mounted ultrasonic radar and a vehicle-mounted surround view system. Background technique [0002] Intelligence is one of the important trends in the development of the automotive industry today, and various sensors are widely used in the field of vehicle active / passive safety. In low-speed scenarios, parking assistance and automatic parking systems have been applied to some mass-produced models in recent years. Most of these systems are based on perceptual input from ultrasonic radar or vision systems, both of which have their pros and cons. The present invention aims to combine the short-range target detection capability of the ultrasonic radar with the auxiliary display capability of the vision system, so as to provide a better experience of the low-speed assisted driving system. [0003] As far as the visual system is concerned, its field of vie...
