Abstract

The invention is applicable to the technical field of computers, and provides a photographing method based on Raspberry Pi. The method comprises the steps of detecting a camera starting instruction, and obtaining a pre-recorded number of tasks using a photographing thread; if the number of the tasks using the photographing thread is greater than 1, carrying out photographing according to the started photographing thread, and updating the number of the tasks using the photographing thread; and detecting a camera closing instruction, updating the number of tasks using the photographing thread according to the camera closing instruction, and closing the camera when the number of tasks using the photographing thread is 0. According to the method, whether a photographing thread is created currently or not is judged according to the task data volume of the photographing thread; when the number of the tasks is greater than 1, it shows that the photographing thread exists, and the photographing thread does not need to be created again; and when the number of the tasks is 0, it shows that no task using the photographing threads exists at the moment, the camera can be closed, and thus the problem of program crash is avoided.

Description

technical field [0001] The present application belongs to the field of computer technology, and in particular relates to a method and device for taking pictures based on Raspberry Pi. Background technique [0002] When using the camera on the Raspberry Pi (RPi) to shoot, the shooting is done through the camera shooting instance. In order to ensure the normal operation of the program, the current shooting thread must be ended before starting a new shooting thread. However, in multi-threading, there is no guarantee that when the camera shooting instance is defined in this thread, the camera shooting instances of other threads have been closed. Therefore, the problem of program crash may occur when shooting. Contents of the invention [0003] The embodiment of the present application provides a method and device for taking photos based on Raspberry Pi, which can solve the problem that the program may crash during shooting. [0004] In the first aspect, the embodiment of the ...
