Abstract

An object detection method and an object detection device are provided. The object detection method is used to detect objects placed on a display screen, wherein a background image is displayed on the display screen. The object detection method includes: acquiring a first image, wherein the first image includes a third image on the display screen. a background image and an image of the object; obtaining a second image, wherein the second image includes a second background image on the display screen and an image of the object, and the second background image is the An image generated by shifting the first background image by a predetermined distance in the first direction; and performing image processing on the first image and the second image to detect an object from the display screen. Through the physical detection method and physical detection device according to embodiments of the present invention, objects can be detected on a display screen displaying complex images, thereby effectively identifying and extracting objects, and improving the overall performance of the system.

Description

technical field

[0001] The invention relates to an object detection method and an object detection device. Background technique

[0002] When the display screen is placed on a flat surface such as a desktop, some additional objects may be placed on the display screen, and at the same time, images may also be displayed on the display screen.

[0003] In scenarios such as interactive games, it may be necessary to use a camera to identify the above-mentioned objects that do not belong to the content displayed on the screen from among the images displayed on the display screen.

[0004] That is, in the above case, while the background image is displayed on the display screen, the camera needs to recognize and extract the object from the background image. At this time, it is necessary to identify and extract the object by separating the background image. However, due to In this case, the background is generally complex and there is lighting interference, which makes the extracti...

Embodiment Construction

[0028] Hereinafter, an object detection method and an object detection device according to embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0029] As mentioned above, in some scenarios such as interactive games, it may be necessary to detect objects from the display screen on which the image is displayed. figure 1 is a schematic diagram of an application scenario of a physical detection method according to an embodiment of the present invention. Such as figure 1 As shown, the user plays the game by rolling dice on the display screen. At this time, since the dice are entities different from the images displayed on the display screen, the game needs to extract the physical dice on the screen. In addition, in addition to the dice, other objects may also need to be extracted on the screen, for example, physical chess pieces may be used in the above game, and so on.

[0030] According to an aspect of an embodiment of ...
