Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a detecting system with get rid of automobile body shadow function, includes camera 1, control panel 2 and display screen 3, camera 1 installs in the automobile body outside, and camera 1 is connected with control panel 2 electricity, can understand, and in the actual process, camera 1 can be a plurality ofly, and after camera 1 installed in the automobile body outside, its position is promptly fixed, consequently, after the camera installation, although receive influence such as light, its color probably changes, but the automobile body profile image of its collection is fixed. The control panel 2 is internally provided with a memory 21 and a processor 22, and after the camera is installed, the initial vehicle body outer contour image is stored in the memory 21, so that a standard is provided for subsequent image processing. The processor 2 receives the image collected by the camera 1 and removes the shadow of the automobile body according to the image of the outer contour of the automobile body, then the processor judges whether the risk exists according to the image of the shadow of the automobile body, and controls the automobile to avoid the obstacle or brake when the risk exists. Simultaneously can show through the risk that display screen demonstration 3 will exist, display screen 3 sets up near the driver, makes things convenient for the driver to look over.

The processor 21 comprises an acquisition module 23, a comparison module 24, an alarm module 25, a display module 26, a judgment module 27 and a driving module 28, wherein the acquisition module 23 acquires image information of the camera 1 and performs binarization processing on the acquired image; the comparison module 24 compares and finds out the part of the image which is the same as the outline of the vehicle body; the judging module 27 judges whether the acquired image has a vehicle body shadow and whether the current real obstacle is dangerous; the driving module 28 is connected with the automobile controller 9 and drives the automobile to avoid obstacles or brake according to the image with the shadow of the automobile body removed, so as to prevent danger and display the existing risk on the display screen 3 through the display module 26; the alarm module 25 starts the alarm device 4 to give an alarm when there is a danger, and reminds the user of the alarm. There are many ways in which the above-described functions can be implemented by the prior art, and will not be discussed in detail here.

Since the final image of the embodiment has the outer contour of the vehicle body removed, the persistent interference of vehicle body shadow is removed for the image recognition of the vehicle-mounted camera, and the detection rate of any vehicle-mounted camera image recognition can be improved.

The method of the present embodiment for acquiring the shadow contour is as follows.

First, contour extraction processing is performed on an original video, in this embodiment, binarization processing is performed first, and then a boundary portion is extracted.

The extracted contours are shown in fig. 3, the contour of all objects is included in the figure, firstly, contours belonging to vehicle body shadows are extracted from all the contours, the vehicle body shadows are connected with a vehicle body and are closely connected with the vehicle body, so that the probability that the vehicle body shadows are probably connected from the vehicle body outer contours is considered, and the installation angle and the position of a camera of each vehicle are the same after the camera is installed on the vehicle body and fixed by a structural member, so that the position of the vehicle body outer contour in an image of each vehicle is considered to be almost the same. I.e. the position of the red line 6 in fig. 4. If the position of the red line exists, the position of the intersection point is recorded, the intersection point is taken as a starting point 0, a search frame 7 is arranged by taking the starting point 0 as a midpoint, the size of the frame can be set by self, and the larger the search frame is, the more time is consumed. And searching for a point 1 connected with the point 0 in the search box, deleting the point 0, then searching for a next connected point 2 in the new search box by taking the new point 1 as the middle point of the new search box, and so on, continuously searching, and finally finding out the shadow contour and deleting the shadow contour.

F. The processor judges whether an obstacle exists according to the image for removing the shadow of the automobile body, controls the automobile to avoid the obstacle or brake when the risk exists, and informs the risk to a user through the alarm device and the display screen.

Since the final image of the embodiment has the outer contour of the vehicle body removed, the persistent interference of vehicle body shadow is removed for the image recognition of the vehicle-mounted camera, and the detection rate of any vehicle-mounted camera image recognition can be improved.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
