A method and device for automatically triggering visual photography

Abstract

The present invention provides an automatic trigger visual camera method and device that includes: the image of the object to be recognized in real time; the image features of the image described in the process of obtaining the imageSimilarity; when judging the first similarity threshold of the similarities that exceeds the preset, send a camera instruction to trigger the camera to take pictures.The invention obtains the image of the object to be recognized in real time, and determines the timing of automatic trigger the camera to take the camera according to whether the similarity between the characteristics and the characteristics of the characteristic template exceeds the preset threshold.The online camera trigger and effectively improve the accuracy and stability of automatic trigger visual camera.

Description

technical field [0001] The invention relates to the technical field of automatic control, and in particular, to a method and device for automatically triggering visual photography. Background technique [0002] Auto-triggered photographing is a technology often used in daily life. For example, the photographing software of a mobile terminal triggers a photographing after detecting a smiling face of a person. For another example, in industrial production, it is usually necessary to automatically trigger photographing of products on the production line. The existing travel switches for automatic triggering and photographing technology used in industrial production mostly use contact switches. This triggering method has a certain delay and is not suitable for scenes that are inconvenient for contact triggering and require high position accuracy; in addition, existing The method of using photoelectric switch to trigger photography has certain delay and instability. For scenes of...

Problems solved by technology

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
