Vehicle model identification device, vehicle model identification system, and vehicle model identification method

Abstract

The purpose of the present invention is to provide a vehicle model identification device, a vehicle model identification system, and a vehicle model identification method, capable of accurately extracting a target vehicle by narrowing down to a specific partial area. The vehicle model identification system includes an imaging device, a display device, a vehicle model identification device, and a bus for connecting the devices, wherein the vehicle model identification device has an input device, a storage device, and a processor. A user performs a search by use of the input device, and the processor causes the display device to display a first vehicle image list, vehicle images, and reference images, which are obtained in accordance with relevant search conditions by using a first rule. Theuser examines the characteristics of the target vehicle model by reference to the reference images and specifies a characteristic partial area. Upon acquiring part specification information for the specified partial area, the processor performs a search on the basis of a second rule and causes the display device to display a second vehicle image list and vehicle images.

Description

technical field [0001] The present disclosure relates to a vehicle type identification device, a vehicle type identification system, and a vehicle type identification method for identifying a vehicle based on a captured image of the vehicle captured by a camera or the like. Background technique [0002] There is known a vehicle identification device that processes a captured image of a vehicle captured by an imaging device such as a video camera to determine the name of the vehicle (see Patent Document 1). [0003] Patent Document 1 discloses a vehicle identification device that includes: a feature extraction unit that extracts a feature of the front grille of the vehicle from a captured image; and a feature storage unit that stores information related to the vehicle. The feature value of the front grille corresponding to each vehicle type, the vehicle confirmation device compares the feature value of the feature value extraction unit with the feature value of the feature va...

Problems solved by technology

However, there is the following problem: In the case of searching for the target car model, the judgment is made based on the characteristics of the entire front grille, so it is possible to extract images including those that are similar to the target car model if only the front grille is photographed but other parts are not similar to the target car model. There are a large number of candidate images including images, so the work becomes very laborious
