Embodiment Construction
[0028] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.
[0029] The present invention pre-arranges optical tags in the physical space that people often browse, and performs position and identity calibration on the entity. When the user browses the tag, it will be acquired by the collection device, and by recording the user's gaze time and The location, you can know the degree of attention to the entity, so as to achieve hotspot acquisition.
[0030] Examples of the above optical tags are figure 1 shown. Optical tags include signal unit (cell) group (or simply referred to as "data bit") and positioning identification (or simply referred to as "flag bit") two parts, where the positioning identification is the above Figure three A larger rectangular frame (the three rectangular frames are called "a group of positioning identifiers"), the positionin...

The invention provides an optical label based user hot spot obtaining method, and the method is high in speed, accuracy and controllability. The method comprises the following steps that 1) entity objects in a target area are marked with optical labels in one to one correspondence; 2) when a user enters the target area and observes the entity objects, a video collector carried by the user himself / herself follows observation of the user, identifies and collects the optical labels corresponding to the entity objects in the target area synchronously, and obtains the watching time length, angle and visual stability degree of each optical label during observation; 3) the attention degree to the corresponding label of the present user is obtained according to the watching time length, angle and visual stability degree of each optical label; and 4) an accumulated value of the attention degree of each optical label within a statistical period is calculated, a rank of the attention degrees of the entity objects corresponding to the optical labels is obtained, and a hot spot of users is obtained according to the rank of the attention degrees.
Description
technical field [0001] The present invention relates to, in particular, a method for acquiring user hotspots based on an optical tag. Background technique [0002] The acquisition of hotspots has important commercial value. Through the acquisition of user hotspots, it is possible to understand the user's preferences and attention content, so as to carry out business development or information mining. With the maturity and popularization of portable virtual reality devices such as smart glasses, people are gradually accustomed to using smart video devices to observe the surrounding world. These smart devices have certain information processing capabilities and can analyze what people see. However, due to the immaturity of image processing technology, it is impossible to directly recognize the objects observed by humans. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides a user hotspot acquisition method bas...
