Embodiment Construction

[0025] A schematic diagram of the overall mechanical structure of an automatic device for realizing large-scale time-lapse photography provided by the present invention is as follows: figure 1 As shown, it is mainly divided into three parts: the wheel spacing adjustment mechanism (1), the motor quick release switching mechanism (2), and the adaptive tripod fixing mechanism (3). The specific installation and use of the mechanical structure of the device are described below.

[0026] The wheel spacing adjustment mechanism (1) is designed based on the basic principle of the scissor mechanism. The omnidirectional wheel (20) is fixed on the support frame (8, 9), and the distance between the two wheels on the same side depends on a pair of support frames (8, 9). ), so the adjustment of the wheel spacing can be realized by adjusting the angle of a pair of support frames (8, 9). The limit bolt (5) plays the role of limit fixation. When it is tightened, the support frame (8, 9) will b...

Abstract

The invention provides an automatic device and control method for realizing large-scale time-lapse photography, which solves the shortcomings of traditional shooting methods such as poor site adaptability, difficult path planning, high cost, and poor portability, and greatly reduces the shooting of large-scale time-lapse photography difficulty. The provided automatic device for realizing large-scale time-lapse photography includes: a wheel spacing adjustment mechanism (1), a motor quick release switching mechanism (2), an adaptive tripod fixing mechanism (3), a motion feedback control system (35), Control panel (34), camera or mobile phone upper computer (33), battery (32), wherein the motion feedback system mainly includes MCU (36), motor driver (37), encoder (38), acceleration gyroscope attitude sensor ( 39). The provided automatic control method for realizing large-scale time-lapse photography includes: the conversion of the operating speed of the photography device and the pulse period of the motor, motion control, shooting trigger control, and path feedback correction.

Description

technical field [0001] The invention relates to a photographic equipment, in particular to an automatic device for realizing large-scale time-lapse photography and a corresponding automatic control method. Background technique [0002] Large-scale time-lapse photography is a method of film and television shooting that simultaneously displays spatial distance and time scale, but the current shooting method is relatively simple: small-scale shooting mostly uses artificial-assisted shooting methods, that is, the photographer moves the tripod step by step to obtain one by one. The photos are finally synthesized in the post-production stage; large-scale shootings often use film and television photography and camera mobile vehicles, commonly known as rail vehicles, for shooting. Rail car shooting requires the laying of tracks in the early stage, and has very high requirements on the size and structure of the track. The adaptability is poor, and the total length of the track is lim...
