Embodiment 1

[0045] Such as image 3 As shown, it is a flow chart of the action type recognition method in Embodiment 1 of the present invention, including the following steps:

[0046] Step 101: Receive the bone data frame collected by the somatosensory device.

[0047] The skeletal data frame includes reference skeletal nodes and at least one setting coordinates of the skeletal nodes in a three-dimensional coordinate space composed of mutually perpendicular horizontal directions, vertical directions, and depth-of-field directions;

[0048] The set skeletal node is determined according to the needs of actual action recognition, and may be any one of the above-mentioned 20 joint points in the skeletal data frame.

[0049] Step 102: Perform denoising processing on the received skeleton data frame.

[0050] It should be noted that step 102 is a preferred step in Embodiment 1 of the present invention. Salt and pepper noise and other types of noise will be generated during image acquisition ...

Embodiment 2

[0151] Such as Figure 5 As shown, it is a flow chart of the program broadcasting method in Embodiment 2 of the present invention, and the program broadcasting method includes the following steps:

[0152] Step 201: Use the action recognition method in Embodiment 1 to determine the action type of at least one combined action for setting the skeletal nodes in the currently received skeletal data frame;

[0153] Step 202: Determine whether the action type of the determined combination action is a valid action type; if yes, execute step 203; if not, go to step 201.

[0154] In this step 202, if the determined action type of the combined action belongs to the preset action type set, it is determined that the determined action type is a valid action type; otherwise, it is determined that the determined action type is an invalid action type.

[0155] Step 203: According to the stored correspondence between the action type of the combination action and the special effect animation, ...

Embodiment 3

[0168] With the same inventive concept as the first embodiment of the present invention, the third embodiment of the present invention provides an action type recognition device, such as Figure 6 As shown, the device includes: a receiving module 101, a first determining module 102, a first judging module 103, a second determining module 104, an action type determining module 105 and a combined action type determining module 106, wherein:

[0169] The receiving module 101 is used to receive the skeleton data frame collected by the somatosensory device, the skeleton data frame includes the reference skeleton node and at least one set skeleton node in a three-dimensional coordinate space composed of mutually perpendicular horizontal direction, vertical direction and depth of field direction coordinate of;

[0170] The first determination module 102 is used to determine the horizontal direction, vertical direction and depth direction of the set bone node in the current bone data ...

Abstract

The invention discloses a method and a device for identifying action types, and a method and a device for broadcasting programs. The method for identifying the action types is used for judging the action types for acquired skeleton data frames in the horizontal direction, the vertical direction and the depth-of-field direction, and mainly includes firstly, judging the direction of a current skeleton data frame according to position relations among set skeleton nodes in adjacent skeleton data frames; and secondly, judging the action types of the set skeleton nodes by the aid of coordinate values of set skeleton nodes in the current skeleton data frame and coordinate values of set skeleton nodes in marked skeleton data frames when the difference between a frame number of the current skeleton data frame and a frame number of each marked skeleton data frame is within a set range. The method and the device for identifying the action types and the method and the device for broadcasting the programs have the advantage that the action types of the set skeleton nodes can be identified, the method for identifying the action types can further be applied to various scenes, and the purpose of controlling the application scenes by the aid of actions of characters is achieved.

Description

technical field [0001] The invention relates to the technical field of image processing and pattern recognition, in particular to an action type recognition method, a program broadcasting method and a device.
