Automatic regulating light supplementing device used for image data acquisition

Abstract

The invention discloses an automatic regulating light supplementing device used for image data acquisition. The automatic regulating light supplementing device comprises a case and locating plates which are arranged at the two sides of the case and symmetrically arranged. A panel is laid and fixed on the front surface of the case. A light intensity detector is arranged on the panel. An ultrasonic range finger is installed on the front surface of the panel above the light intensity detector. One side of the ultrasonic range finger of the front surface of the panel is provided with a light regulator. The ultrasonic range finger comprises an ultrasonic transducer. The beneficial effects are that 1, the distance of the part to be measured can be detected through the ultrasonic range finger, the light supplementing intensity can be regulated and the image detection effect can be enhanced; 2, the light supplementing brightness can be automatically regulated according to the external light intensity by detecting the external light intensity so that the image information acquisition signal is enabled to be more stable and the acquisition effect can be enhanced; and 3, the working stability of the equipment can be enhanced through automatic heat radiation of the equipment so that the service life of the equipment can be enhanced.

Description

technical field [0001] The invention belongs to the field of lighting equipment, and in particular relates to an automatic adjustment type supplementary light device for image data acquisition. Background technique [0002] When the CCD sensor, traffic camera and surveillance camera are collecting images, under the condition of poor ambient light, it is necessary to provide supplementary lighting to the location to be collected to improve the effect of image collection. Traditional supplementary light devices can only directly illuminate the part to be illuminated, and cannot adjust the intensity of supplementary light according to the intensity of external light, and at the same time cannot adjust different lighting brightness according to the position of supplementary light at different distances. [0003] The application number is: 201510587260.8 Chinese patent, the specific content is: image acquisition equipment supplementary light device and method, including the first...
