Embodiment 1

[0159] refer to figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 with Image 6 , an engineering vehicle anti-theft alarm system based on omnidirectional computer vision, including a microprocessor 6, an omnidirectional visual sensor 13 for monitoring the antitheft situation of an engineering vehicle, and a communication module for communicating with the outside world, the omnidirectional visual The output of the sensor 13 is connected with the microprocessor 6 through the USB interface 14. The omnidirectional visual sensor 13 includes an outer convex catadioptric mirror 1 for reflecting objects in the monitoring field, and a black cone for preventing light refraction and light saturation. 2. A transparent cylinder 3 and a camera 5. The convex catadioptric mirror surface 1 is located above the transparent cylinder 3, the convex catadioptric mirror surface 1 faces downward, and the black cone 2 is fixed at the center of the convex portion of the catadioptric mirror su...

Embodiment 2

[0283] The effect of the invention produced by the above-mentioned embodiment 1 is to detect whether the suspended swinging object on the engineering vehicle swings through the visual detection around the exterior of the engineering vehicle. When the components outside the car body (such as tires, etc.) or the construction vehicle is moved in other ways, the suspended swinging object will swing or vibrate up and down. Therefore, the detection of whether the hanging swinging object swings or vibrates through the omnidirectional visual sensor is also anti-theft. effect.

Embodiment 3

[0285] The inventive effect produced by the above-mentioned embodiment 1 can be used as an auxiliary tool for engineering vehicle operators to expand their field of vision. Due to the current layout of engineering vehicles and other reasons, for engineering vehicle operators, the front or rear vision blind spots are too large, and there are often people The occurrence of casualty accidents. Therefore, it is necessary to expand the field of view of engineering vehicles and further improve the field of vision performance of engineering vehicles to improve the safety and operating efficiency of engineering vehicles. Especially for remote engineering vehicles, the operator is by observing the video If the screen of the monitoring system monitor is used to remotely control the construction vehicle at the site, if the screen displayed on the monitor is only a "window" of the scene, the operator must adjust the monitoring position of the camera lens from time to time to control the con...

Abstract

This invention relates an engineering car anti-stealing alarm system based on omnibearing vision of a computer including a micro-processor, an omnibearing vision sensor for monitoring situation of anti-stealing to the car, a communication module communicating with the outside, in which, the output of the sensor is connected with the micro-processor and a digital image process technology and a network communication technology are used together with the sensor to judge if some one enters into the monitored sphere and find out some reasonable character criteria in the stolen period to inform monitoring persons to pay attention to the event and record the current video images for analyzing and solving the case later.

Description

(1) Technical field [0001] The invention belongs to the application of all-round computer vision sensor technology, image recognition technology, computer control technology and wireless network communication technology in anti-theft aspects of engineering vehicles and engineering vehicle accessories parked on construction sites or open fields. (2) Background technology [0002] With the vigorous development of China's economy, various construction vehicles are developing rapidly. Construction vehicles are generally parked at the construction site or in open spaces at night. At present, there is almost no anti-theft protection for construction vehicles at night. Many people have never thought that construction vehicles are also Someone will steal it. After work, the well-used construction vehicles are always parked randomly on the roadside and on the construction site, without any anti-theft equipment, which leaves opportunities for car thieves. [0003] In just two months i...
