A time-lapse photography method and device with adjustable camera moving speed

Abstract

The invention relates to the technical field of time-lapse photography, and specifically discloses a method and device for time-lapse photography with adjustable camera moving speed. The method includes: setting motion commands to control the rotation of the motor to drive the corresponding motion of the sliding block; setting key points to set commands to control the motor Stop the rotation, mark the position where the slider stops as the key point; set the movement speed of the corresponding key point; set the command according to the running speed of each key point, the distance between two key points of adjacent labels and the time-lapse photography , calculate the total number of time-lapse photography photos and the total time-lapse photography time; let the camera perform time-lapse photography according to the photography interval time and exposure time. The present invention enables the operator to know the total number of photos that can be taken in the time-lapse photography process and the total duration of the time-lapse photography before the time-lapse photography through the setting of key points and time-lapse photography, so as to facilitate timely adjustment of the key points Location information, camera operating speed, etc., so that photos that meet the needs can be obtained through time-lapse photography.

Description

technical field [0001] The invention relates to the technical field of time-lapse photography, in particular to a method and device for time-lapse photography with adjustable camera movement speed. Background technique [0002] Time-lapse photography is also called time-lapse photography and time-lapse video. It is Time-lapse photography in English. It is a shooting technique that compresses time. It is also called time-lapse video. What it takes is a group of photos or videos. Later, through photo concatenation or video frame extraction, the process of minutes, hours, or even days and years is compressed into a short period of time and played as a video. In a time-lapse photography video, the slow changing process of an object or scene is compressed into a short period of time, presenting a strange and wonderful scene that cannot be detected by the naked eye. Time-lapse photography can be considered as a process opposite to high-speed photography, and is usually used in sh...

Problems solved by technology

For the second method, manual participation is required throughout the shooting process. It is necessary to adjust the speed and position of the translation on the slide rail in real time according to the camera requirements, and observe the progress of time-lapse photography in real time, because a slight mistake will result in missing material and lead to shooting fail

However, there is no corresponding design in the prior art that can intuitively locate multiple key points and multi-stage speed regulation (including variable speed), and can grasp the technical scheme of time-lapse photography composite film duration in advance, so the existing scheme is very time-consuming and expensive for the staff. Energy, user experience is also poor
