Problems solved by technology
However, handheld devices similar to infrared laser emitters are not commonly used devices, and the above-mentioned method for identifying the user action mark area is carried out using the characteristics of light emitted by infrared laser emitters. Therefore, when similar infrared laser emitters When a handheld device fails, it is usually difficult for users to find a replacement handheld device before it is repaired or replaced with a new handheld device, and it is also impossible for users to interact with the terminal through common visible light sources such as flashlights, which affects user experience.

Embodiment Construction
[0059] In the human-computer interaction, the human-computer interaction can be performed through the user's actions, and in the process of the human-computer interaction through the user's actions, it is necessary to obtain the position of the user's limbs at each moment, and then determine the user's trajectory. Based on this and the problems existing in the prior art, embodiments of the present invention provide a method and device for determining an image-based user action identification area.
[0060] In practical applications, when directly detecting the position of the user's limbs at each moment, it is easily affected by factors such as the current ambient light, for example, the user's limbs are located in a shadow area, etc., resulting in excessive detection errors. Considering these factors, when applying the solution provided by the embodiment of the present invention to determine the user action identification area, the user is required to carry a visible light sou...

The embodiment of the present invention discloses a method and device for determining an image-based user action identification area, which relates to the technical field of image processing, including: setting the target grayscale processing as the grayscale processing with the highest priority in a preset grayscale processing list; Perform target grayscale processing on the target image; detect whether there is a light source mapping area of visible light in the target image according to the grayscale processed image; if there is, determine the user action identification area in the target image according to the detected light source mapping area; If it does not exist, update the target grayscale processing to the next grayscale processing of the current grayscale processing in the preset grayscale processing list according to the order of priority from high to low, and return to execute the target grayscale processing on the target image The steps are changed until it is detected that there is a light source mapping area of visible light in the target image, or all the grayscale processing in the preset grayscale processing list is traversed. Application of the solutions provided by the embodiments of the present invention can provide user experience.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and device for determining an image-based user action identification area. Background technique [0002] With the development of human-computer interaction technology, human-computer interaction has developed from the initial human-computer interaction using keyboard, mouse, remote control, etc., to advanced human-computer interaction using human voice, action, etc. Wherein, when the human-computer interaction is completed by recognizing the user's action, the user's action track can be identified and obtained through the touch screen, and the user's action track can also be obtained by identifying the motion track of the user's handheld device. [0003] In the prior art, since the invisible light emitted by the infrared laser transmitter is very different from the visible light emitted by common light sources such as flashlights, it has superior perform...
