Embodiment Construction

[0026] Embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0027] Such as figure 1 As shown, a human body three-dimensional data tracking and recognition method with anti-interference function in dense crowds uses a combination of three-dimensional human body data tracking and recognition and face data tracking and recognition, which specifically includes the following steps:

[0028] 1) Determine the main target person as the object of tracking and identification;

[0029] Including finding the current main target person, judging whether the new target is a new main target person when a new target appears, updating the current main target person if so, and retrieving the current main target person when the current main target person is lost.

[0030] After the 3D camera captures the 3D human body data set D and its corresponding depth set Z of multiple target people, the current main target person is foun...

Abstract

The invention discloses a three-dimensional somatic data identification method with an anti-interference function in intensive people flow. The three-dimensional somatic data identification method is characterized in that three-dimensional somatic data tracking identification and two-dimensional human face position information tracking identification are combined, and movements of the body of a main target person are tracked and identified after the main target person is determined, wherein determining of the main target person includes seeking the current main target person, judging whether a newly appeared target is the main target person, updating the main target person on yes judgment and re-seeking the current main target person when the current main target person is lost. The three-dimensional somatic data identification method leads the main target person to be stably locked in the public occasions of intensive people flow by aid of three-dimensional somatic data tracking identification, effectively separates the background and the crowd of onlookers, and accordingly is ensured to have the anti-interference function on the multi-target background with intensive people flow.

Description

technical field [0001] The invention relates to the field of three-dimensional image processing, in particular to a method for tracking and identifying three-dimensional human body data with an anti-interference function in dense crowds. Background technique [0002] Human-computer volley interaction means that users can operate and control the display device without actually touching any display device, bringing users a magical and sci-fi experience. With the maturity of hardware and software technology, volley interactive technology is becoming more and more mature. The volley interactive system has the characteristics of novelty, easy realization and maintenance, convenience and flexibility. [0003] Volley interactive technology can be applied in many fields. From the perspective of advertising, merchants can display their products in a way that interacts with consumers. The interaction process can enhance consumers' interest and desire to buy, and merchants can also s...
