Problems solved by technology

[0004] The traditional car-following method in the visual part of automatic driving uses a camera with a fixed focal length. This method usually has the following problems: if the distance between the current vehicle and the target vehicle is relatively close or the target vehicle is large in size, if the camera’s field of view is small, Then the vehicle will occupy most of the images. At this time, the camera will not be able to capture enough surrounding environment information to judge, so that it will not be able to give an accurate and safe driving strategy; The medium is very small, and the accuracy of detection and tracking in the vision algorithm will decrease at this time

Embodiment 1

[0075] see figure 1 , figure 1 It is a schematic flowchart of a method for adjusting the field of view angle of a camera provided by an embodiment of the present invention. The method is applied in automatic driving and can be implemented by a device for adjusting the field of view of the camera. The device can be realized by means of software and / or hardware, and generally can be integrated in a vehicle-mounted computer, a vehicle-mounted industrial personal computer (Industrialpersonal Computer, IPC), etc. In the vehicle-mounted terminal, the embodiments of the present invention are not limited. like figure 1 As shown, the method for adjusting the field of view of the camera provided in this embodiment specifically includes:

[0076] 110. Obtain the road image including the target vehicle captured by the current camera.

[0077] Wherein, the target vehicle is a vehicle that may affect the driving strategy of the current vehicle, for example, a vehicle in front, a vehicle...

Embodiment 2

[0095] see figure 2 , figure 2 It is a schematic flowchart of a method for adjusting the field of view angle of a camera provided by an embodiment of the present invention. This embodiment is optimized on the basis of the above embodiments, such as figure 2 As shown, the method includes:

[0096] 210. Obtain a road image including the target vehicle captured by the current camera.

[0097] 220. Split the road image according to different faces of the target vehicle, and obtain local detection frames of each face of the target vehicle in the split image.

[0098] 230. For any local detection frame, determine the ratio of the local detection frame to the split image, and if the ratio is greater than a preset first ratio threshold, increase the field of view of the current camera.

[0099] Exemplarily, increasing the field of view of the current camera may be implemented in any of the following two ways:

[0100] (1) The method of directly adjusting the field of view of t...

Embodiment 3

[0117] see image 3 , image 3 It is a schematic flowchart of a method for adjusting the field of view angle of a camera provided by the embodiment of the present invention. This embodiment is optimized on the basis of the above embodiments, and introduces the specific method of splitting the road image according to the different faces of the target vehicle. Split method. like image 3 As shown, the method provided in this embodiment specifically includes:

[0118] 310. Obtain a road image including the target vehicle currently captured by the camera.

[0119] 320. Recognize the road image based on the preset vehicle target detection model to obtain an overall detection frame of the target vehicle.

[0120] Wherein, the preset vehicle target detection model is obtained by using the road sample image marked with the vehicle position to train the pre-established initial neural network model.

[0121]Among them, the vehicle position in the road sample image is marked by the ...

Abstract

The embodiment of the present invention discloses a method and device for adjusting the field of view angle of a camera. The method includes: acquiring a road image including a target vehicle captured by the current camera; Split to obtain the local detection frame of each plane of the target vehicle in the image after the split; for any local detection frame, determine the ratio of the local detection frame to the image after the split, and according to the ratio The value determines how the current camera field of view is adjusted. By adopting the above technical solution, the field of view of the currently working camera can be adjusted in real time according to the images observed in real time, so as to capture sufficient surrounding environment information.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to a method and a device for adjusting the viewing angle of a camera. Background technique [0002] With the development of science and technology, emerging technologies such as "autonomous driving" and "unmanned vehicles" have gradually entered people's field of vision. Among them, high-precision vehicle detection and identification, judgment of ever-changing road conditions, and appropriate speed and direction adjustment are all technical problems that need to be overcome in the field of unmanned vehicles. Compared with the analysis and processing of road information such as lane lines, stationary obstacles, traffic lights, and traffic signs, and pedestrian information in road areas, the processing of vehicle information on the road is often more complicated. The speed, distance, and steering information of the surrounding vehicles are instantaneous, variable, and unpre...
