Embodiment Construction

[0023] The implementation of the key frame motion range detection system of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] A general fixed projector is composed of transmission, film feeding, optics, sound reproduction, body and electrical appliances. There are no amplifiers, speakers, etc. attached to the portable projector. The functions of each part of the movie projector are as follows:

[0025] Transmission part: The kinetic energy is supplied by the motor and transmitted to the transmission part through gears, sprockets, toothed belts, worm gears, etc. Three-phase synchronous motors are often used for fixed types; single-phase motors are generally used for mobile types; interlocking motors are often required for special models to ensure synchronization between devices.

[0026] Film transport part: Send the rolled film from the supply disc to the film window for irradiation to reflect the picture, and conve...

Abstract

The invention relates to a key frame action amplitude detection system, which includes: a time reading device, which is arranged near an indoor projector and is used to receive each time stamp of each video frame sent by the indoor projector; a key frame judgment device, and the The time reading device is connected to receive each time stamp of each video frame, extract each time stamp of each key video frame from each time stamp of each video frame, and calculate the distance from the indoor projector at the current moment. When the time difference between the start of the screening time and the timestamp of a certain key video frame matches, a key frame judgment signal is sent; otherwise, a non-keyword judgment signal is sent; body shape recognition equipment is used to judge the action of the corresponding actor based on the outline of the sub-image to be analyzed. Type, to determine the action level of the content currently being projected by the corresponding indoor projector based on the action type of the corresponding actor. Through the present invention, an effective content analysis mechanism is determined.

Description

technical field [0001] The invention relates to the field of computer detection, in particular to a key frame motion range detection system. Background technique [0002] There are different types of movie projectors, which generally fall into two categories: stationary and mobile. According to the width of the projected film, it can be divided into different projectors such as 70mm, 35mm, 16mm, 8.75mm and 8mm. For some special forms of movies, it is also equipped with three-dimensional, panoramic, ring screen, dome screen, giant screen and other projectors. [0003] There is a large flat-disk circulation disk behind the projector, which can accommodate the entire length of the film. After the screening, it can be shown in the next session without rewinding the film. In order to simplify the operation, some mobile narrow film projectors are designed with an automatic film feeding device in the film feeding channel, and some use a film box insertion device. In order to sho...
