Problems solved by technology

[0002] Most drivers have been troubled by the obstacle avoidance operation that cannot take into account all directions when driving a vehicle, and the movement of the vehicle driving in the blind spot area (such as parking or driving on a narrow road) is usually an important cause of trouble

Embodiment Construction

[0032] In order to clearly and completely disclose the features, purposes and functions of the present invention, the relevant internal structure and design points of the device of the present invention are described below, and the details are as follows:

[0033] see figure 1 As shown, this figure is a schematic flow chart of an embodiment of the method for assisted guidance of a vehicle moving image according to the present invention. In this embodiment, it is mainly to identify the images at different time points to find out the moving features, and calculate the moving direction of the features in the image space from the features, so that the moving state of the vehicle can be obtained, for example: steering . Then estimate the trajectory of the vehicle from the moving state and display it on the screen to provide the driver with reference. Next, the operation flow of the method is described. Firstly, step 20 is performed to obtain a first image about the external envir...

Abstract

The invention discloses a mobile image-aided guidance method and a mobile image-aided guidance system for vehicles, which utilize a single image acquisition device to be matched with a control device with image processing, image identification as well as the estimation and calculation of an image space distance to provide intact image-aided information when the vehicles move. The method can produce movement tracks of the vehicles, perform the conversion of survey perspectives, and identify image characteristics in images for distance estimation. The method and the system can be applied to various different vehicle forms, solve the problem of mobile guidance of the vehicles, and can also assist the vehicles with the lane change, parking assistance and blind-spot detection.

Description

technical field [0001] The present invention relates to a vehicle movement assistance method, in particular to a vehicle moving image-assisted guidance method and system that utilizes image recognition to judge vehicle movement status and identify obstacles and lane marks as guidance auxiliary information . Background technique [0002] Most drivers have been troubled by the inability to take into account the obstacle avoidance operation in all directions when driving a vehicle, and the movement of the vehicle driving in the blind spot area (such as parking or driving on a narrow road) is usually an important cause of the trouble. The current electronic technology has developed to use sensors to assist driving safety, the most common ones are distance sensors (ultrasonic, infrared, millimeter wave and laser, etc.) and image sensors (CCD / CMOS). The distance sensor is mainly used for unidirectional obstacle avoidance passive warning (such as: adaptive cruise system, reversing...
