Embodiment Construction

[0045] figure 1 is a schematic diagram of an obstacle detection system according to the present invention. Please refer to figure 1 , the obstacle detection system 10 includes an image acquisition unit 12 and an obstacle detection device 15 . The obstacle detection system 10 is suitable for a vehicle, and the image acquisition unit 12 is arranged on the vehicle to acquire environmental images around the vehicle. For example, the image acquisition unit 12 may be disposed in front of the vehicle, such as above the windshield of the vehicle, to acquire the lane image in front of the vehicle. The image acquisition unit 12 is, for example, an image sensor with a Charge Coupled Device (CCD) or a Complementary Metal-Oxide Semiconductor (CMOS) element, and is used to acquire images of the surrounding environment of the vehicle. More specifically, the image acquisition unit 12 is, for example, a driving record camera with a video recording device, or a digital camera with a photogra...

Abstract

The invention provides an obstacle detecting device. The obstacle detecting device comprises a storage unit, a quasi-vertical edge detecting module, an intersection determining module, a position determining module and an obstacle detecting module. The quasi-vertical edge detecting module receives input images and performs quasi-vertical edge detection on the input images to obtain a plurality of quasi-vertical edges; the intersection determining module determines whether the quasi-vertical edges are intersected with a preset virtual horizon; if so, the position determining module determines whether one end of one of the quasi-vertical edges intersected with the virtual horizon is located inside an detecting area; if so, the obstacle detecting module determines existence of obstacles.

Description

[0001] The present invention is a divisional application of the invention patent application with the application number 201410102894.5 and the invention name "obstacle detection device" filed on March 19, 2014. technical field [0002] The present invention relates to an obstacle detection device, and in particular to an image processing technology-based obstacle detection device. Background technique [0003] With the increasing number of cars, the chances of road accidents also increase every year. Obviously, in addition to the continuous advancement of vehicle technology in the power part, the improvement of safety during driving is also another topic that needs attention. Studies have shown that if drivers can be warned before a collision occurs, the probability of road accidents can be greatly reduced. Therefore, a good and accurate obstacle detection and warning system is actually a very important link in the current vehicle safety system. [0004] Generally speakin...
