Automatic triggering visual photographing method and device

Abstract

The invention provides an automatic triggering visual photographing method and device. The method comprises the following steps: acquiring an image of a to-be-recognized object in the moving process in real time; extracting the image features of the image, and obtaining the similarity between the image features and a preset feature template; and when it is judged that the similarity exceeds a preset first similarity threshold, sending a photographing instruction to trigger a camera to photograph. According to the invention, the image of the to-be-identified object in the moving process is acquired in real time, and the opportunity of automatically triggering the camera to photograph is determined according to whether the similarity between the characteristics of the image and the characteristic template exceeds the preset threshold, so that the image can be captured at a high speed, and dynamic online photographing triggering is realized; and the accuracy and stability of automaticallytriggering visual photographing are effectively improved.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a method and device for automatically triggering visual photography. Background technique [0002] Automatically triggering photos is a technology that is often used in life. For example, the camera software of a mobile terminal triggers photos after detecting a smiling face. For example, in industrial production, it is usually necessary to automatically trigger photos of products on the production line. Existing travel switches for automatic trigger camera technology used in industrial production mostly use contact switches. This trigger method has a certain delay and is not suitable for scenarios where contact triggering is inconvenient and high position accuracy is required. In addition, the existing The way of using a photoelectric switch to trigger the photo has a certain delay and instability. For the scene of continuous movement (the object to be photographed has...

Existing travel switches for automatic trigger camera technology used in industrial production mostly use contact switches. This trigger method has a certain delay and is not suitable for scenarios where contact triggering is inconvenient and high position accuracy is required. In addition, the existing The way of using a photoelectric switch to trigger the photo has a certain delay and instability. For the scene of continuous movement (the object to be photographed has a certain speed), the stability of the photo is not high, and the existing camera body trigger technology requires close to Trigger recognition in a static state, not suitable for continuous motion scenes
