Embodiment Construction

[0055] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0056] Implementation column 1:

[0057] Please refer to figure 1 as shown, figure 1 It is a structural schematic diagram of a right-turn safety warning system for a heavy-duty truck in Embodiment 1 of the present invention. This embodiment provides a right-turn safety warning system for a heavy-duty truck. The system includes a fisheye camera 1, an ultrasonic sensor 2, a signal processing unit 3, a central control center 4, a liquid crystal display 5, and an accelerator controller 6;

[0058] The fisheye camera 1 is arranged on the rear half of the front of the truck, the ultrasonic sensors 2 are multiple, and are respectively located on the right side of the truck compartment, the signal processing unit 3 is arranged inside the cab, and the cen...

Abstract

The invention discloses a right turn safety warning method for a heavy truck, which relates to the technical field of vehicle driving safety. The main steps of the method are as follows: when a right turn signal is activated, a fisheye camera and an ultrasonic sensor are activated to collect information on the right turn blind area of ​​the truck. The fisheye camera is calibrated by the disc calibration plate to correct the distorted image. The HOG+SVM algorithm is used to detect pedestrians in the right turning blind spot of the truck, and then the correlation filtering and fusion algorithm based on color feature statistics and HOG feature representation is used to track the pedestrians in the right turning blind spot of the truck in real time. According to the lateral distance between people and vehicles measured by the ultrasonic sensor, the turning speed of the truck is controlled to prevent the driver from misoperation.

Description

technical field [0001] The invention relates to the technical field of vehicle driving safety, in particular to a safety early warning method for a right turn of a heavy-duty truck. Background technique [0002] In recent years, due to the needs of economic development and industrial transportation, the number of trucks in my country has continued to increase. Due to its "big, long, and high" characteristics, there are many blind spots in the truck, which leads to continuous occurrence of vehicle accidents. Especially the "death meniscus" accident, that is, when the truck turns right, the driver cannot notice whether there are pedestrians around the right side of the truck due to the inner wheel difference and the blind spot of the right rearview mirror, which leads to the occurrence of the accident . [0003] The Chinese patent with the patent publication number CN104401254A discloses a human body sensing system in a dead zone when a truck turns, and relates to an infrare...
