Abstract

The present application is applicable to the field of computer technology, and provides a Raspberry Pi-based photographing method, comprising: detecting a camera startup instruction, and obtaining a pre-recorded number of tasks using photographing threads; the number of tasks using photographing threads is greater than 1, according to the The opened camera thread takes pictures, and the number of tasks using the camera thread is updated; the camera shutdown instruction is detected, and the number of tasks using the camera thread is updated according to the camera shutdown instruction. The number of tasks using the camera thread is 0, and the camera is turned off. In the above method, it is judged whether a photo-taking thread has been created currently according to the task data amount of the photo-taking thread. When the number of tasks is greater than 1, it means that a photo-taking thread already exists, and there is no need to create it again, and when the number of tasks is 0, it means that at this time If there is no task using the camera thread, the camera can be turned off, thus avoiding the problem of program crash.

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 ...
