A mobile phone water-sensitive paper auxiliary photographing device and photographing method

Abstract

The invention discloses a mobile phone water-sensitive paper auxiliary photographing device and a photographing method. In the auxiliary photographing device, the mobile phone clamping frame is connected with a two-dimensional mobile platform through a bolt structure, and the two-dimensional mobile platform is installed on a liftable column. The column and The control board and the soft box are installed on the base through the bottom plate, and the paper placing platform is installed in the base. When shooting water-sensitive paper, first clamp and fix the mobile phone, and then adjust the left and right, front and rear positions and heights of the mobile phone so that the camera of the mobile phone is facing the water-sensitive paper photo area in the base through the soft box; place the water-sensitive paper behind the paper platform Press the switch on the control panel, and the device can automatically take pictures of the water-sensitive paper one by one. The invention can be widely used in fields such as field production and scientific experiments, enables the mobile phone to take high-quality and fast water-sensitive paper photos, and is easy to use and low in manufacturing and maintenance costs.

Description

technical field [0001] The invention belongs to the technical field of auxiliary machinery for agricultural plant protection, in particular to a mechanical device for assisting photographing with water-sensitive paper for mobile phones. Background technique [0002] Agricultural water-sensitive paper is often used in fields, agricultural machinery laboratories and other environments to measure the droplet deposition distribution of different spray methods, to detect the spraying effect of equipment, and to evaluate the performance and operating parameters of spraying equipment. It has a wide range of uses . The principle of water-sensitive paper is to develop color after encountering a solution such as water, thereby forming a deposition pattern of sprayed droplets on the paper surface. A clear water-sensitive paper image is the premise and basis for obtaining data such as droplet density, particle diameter, and number of droplets, so a stable image acquisition method is pa...
