Embodiment 1

[0049] Referring to Figures 1 to 9, an intelligent parking assistance device based on omnidirectional computer vision includes a visual sensor 1, a microprocessor 7 for making parking assistance decisions, and a display unit 8 for displaying the surrounding conditions of the vehicle. Visual sensor connects microprocessor 7, and described microprocessor 7 comprises: image display unit, is used to gather the signal of visual sensor, and outputs to display unit 8; Described visual sensor is omnidirectional visual sensor, and this omnidirectional The visual sensor is installed on the top of the middle of the vehicle, and the omni-directional visual sensor includes an outer convex catadioptric mirror surface 2 for reflecting objects in the surrounding area of ​​the vehicle. Cone 4, black cone 4 is fixed on the center of the convex part 2 of the catadioptric mirror surface, used to support the transparent cylinder 3 body of the convex catadioptric mirror surface, and is used to photo...

Embodiment 2

[0141] With reference to Fig. 1~Fig. 11, same as above-mentioned embodiment 1, also can use this device to observe the situation around the vehicle during the driving process of the vehicle (non-reversing), broaden the field of vision of the driver, and reduce the occurrence of accidents.

Embodiment 3

[0143] With reference to Fig. 1~Fig. 11, same as above-mentioned embodiment 1, this implementation is the application on some engineering vehicles, because the driver's vision of engineering vehicles is smaller than general vehicles, and engineering vehicles are relatively bulky, adopt this device and will It is installed in the middle of the engineering vehicle, which can broaden the field of vision of the engineering vehicle driver.

Abstract

The auxiliary device includes vision sensor, microprocessor in use for carrying out aided decision making for parking, and display unit in use for displaying situation around vehicle. Being connected to microprocessor, the vision sensor is all-directional vision sensor. The microprocessor includes image display unit, scaling module for sensor, image expansion module, module for detecting edges of obstructers around vehicle, module for calculating minimum distance to edges of obstructers around vehicle, module for alarming obstructers, and back running knowledge base etc. The invention provides visual images around vehicle, gives hint of turning angle of steering wheel to driver so as to assistant procedure for driver to run back vehicle.

Description

(1) Technical field [0001] The invention relates to the application of omnidirectional visual sensor technology, image recognition technology and computer control technology in vehicle parking, especially an intelligent auxiliary device for vehicles. (2) Background technology [0002] With the development of my country's automobile industry and the continuous improvement of people's living standards, on the one hand, the number of automobiles has increased year by year, with an annual growth rate of 7 million units, making my country's roads, streets and parking lots crowded, and the rotatable space is becoming more and more On the other hand, the growth of the absolute number of vehicles has caused more and more new drivers and non-professional drivers, and more and more disputes caused by reversing. In the proportion of car accidents in 2002, the accidents caused by backing accounted for 21%. Backing has become a headache for people. Even experienced drivers complain that b...
