Abstract
A method and a device for acquiring a vehicle feature are provided. In the method, a to-be-processed image including a vehicle is acquired. A feature element of the vehicle is then recognized from the to-be-processed image, where the feature element may be a side element and an element of a vehicle end, and the vehicle-end may be a head of the vehicle or a rear of the vehicle. Based on a position of the side element in the to-be-processed image and a position of the element of the vehicle end in the to-be-processed image, a side region of the vehicle and an end region of the vehicle are determined.
Claims16
A method for acquiring a vehicle feature, comprising:
- acquiring a to-be-processed image comprising a vehicle;
- recognizing a feature element of the vehicle from the to-be-processed image, wherein the feature element comprises a side element and an element of a vehicle end, and the vehicle end comprises a head of the vehicle or a rear of the vehicle, the side element comprises one or more of a wheel, a side window, a rearview mirror, and a door;
- determining, in the to-be-processed image, a side region of the vehicle and an end region of the vehicle, based on a location where the side element is in the to-be-processed image and a location where the element of the vehicle end is in the to-be-processed image;
- and
- acquiring a side region feature based on the side region, and an end region feature based on the end region, wherein the side region feature comprises a location where a vertex of the side region is in the to-be-processed image, a location where a center point of the side region is in the to-be-processed image, or a location where a midpoint of an edge of the side region is in the to-be-processed image;
- and
- determining a relative position of the vehicle to an image capturing device, based on the end region feature, the side region feature and a shooting parameter of the to-be-processed image.
A device for acquiring a vehicle feature, comprising:
- an image acquisition unit configured to acquire a to-be-processed image comprising a vehicle;
- an image recognition unit configured to recognize a feature element of the vehicle from the to-be-processed image, wherein the feature element comprises a side element and an element of a vehicle end, and the vehicle end comprises a head of the vehicle or a rear of the vehicle, the side element comprises one or more of a wheel, a side window, a rearview mirror, and a door;
- a region determination unit configured to determine, in the to-be-processed image, a side region of the vehicle and an end region of the vehicle, based on a location where the side element is in the to-be-processed image and a location where the element of the vehicle end is in the to-be-processed image;
- and
- a feature acquisition unit, configured to acquire a side region feature based on the side region, and acquire an end region feature based on the end region, wherein the side region feature comprises a location where a vertex of the side region is in the to-be-processed image, a location where a center point of the side region is in the to-be-processed image, or a location where a midpoint of an edge of the side region is in the to-be-processed image;
- and
- a relative position determination unit, configured to determine a relative position of the vehicle to an image capturing device, based on the end region feature, the side region feature and a shooting parameter of the to-be-processed image.
