Problems solved by technology

[0002] At present, many vehicles have been equipped with ultrasonic rearward warning systems, and more and more vehicles will be equipped with rearview cameras. Some rearward warning systems simply add the distance information of obstacles detected by ultrasonic radar to the rearview image and display them together. Without effective use of ultrasonic radar information and camera information

Embodiment

[0025] Such as figure 1 As shown, a vehicle backward ultrasonic and camera fusion alarm processing method includes the following steps:

[0026] Step 1. When the vehicle gearbox is placed in reverse gear, the rearward warning system is activated, and the ultrasonic sensor and image processing unit are initialized;

[0027] Step 2. At any time during the reversing process, the user selects the auxiliary and warning information providing mode through the man-machine interface. The providing mode includes the traditional ultrasonic reversing radar display mode, the normal rear view superimposed ultrasonic beam information mode, and the superimposed rear view superimposed ultrasonic bundle information mode;

[0028] Step 3. Ultrasonic sensors detect obstacles and generate depth images;

[0029] Step 4. Determine whether an obstacle is detected, if yes, give a sound warning, and go to step 5, if not, go directly to step 5;

[0030] Step 5. Determine whether the traditional ultra...

Abstract

The invention relates to a warning treatment method for fusion of vehicle backward ultrasonic and a camera. The method comprises the following steps of: 1) placing a vehicle gearbox at a reverse gear so as to activate a backward warning system; 2) selecting a supply manner of assistance and warning information through a human-computer interface; 3) detecting barriers by an ultrasonic sensor, and generating a depth image; 4) judging whether barriers are detected or not, if yes, performing sound warning, and executing step 5), and otherwise executing the step 5) directly; 5) judging whether the supply manner for assistance and warning information is the traditional ultrasonic reversing radar display mode, if yes, executing the step 1), and otherwise executing step 6); 6) starting the camera and collecting images; and 7) correcting the distortion of an original input image by an image processing unit. Compared with the prior art, the warning treatment method related by the invention has the advantages that the cost is low, the method is intuitive and visual, the positions of objects are judged more accurately and the like.

Description

technical field [0001] The invention relates to a vehicle alarm method, in particular to an alarm processing method for fusion of vehicle backward ultrasonic waves and cameras. Background technique [0002] At present, many vehicles have been equipped with ultrasonic rearward warning systems, and more and more vehicles will be equipped with rearview cameras. Some rearward warning systems simply add the distance information of obstacles detected by ultrasonic radar to the rearview image and display them together. However, the ultrasonic radar information and the camera information are not effectively used. The rearward warning system in the present invention can intuitively and real-time display the obstacle information detected by the ultrasonic radar in the rear view image in a way that the driver can easily observe, so as to achieve better auxiliary reversing and collision warning. Effect. Contents of the invention [0003] The object of the present invention is to pro...
