Problems solved by technology

However, since the color of the veins and the leaf surface is similar, and the color difference between the veins and the leaves is not necessarily uniform, it is often difficult to identify accurately, so the effect of its practical application is greatly limited.

Embodiment Construction

[0016] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0017] Such as figure 1 As shown, a broad-leaf plant leaf vein measuring instrument mainly includes a movable platform 1 for placing leaves, the color of the table top of the movable platform 1 is set to white, and the length, width, and height of the table are 300mm*120mm*5mm, respectively. A light-shielding box 2 is arranged above the movable platform 1. The bottom of the light-shielding box 2 is hollow for blocking external light. The light-shielding box 2 is connected to the bracket 3. An illuminating lamp 4 with internal brightness, a camera 5 and a strip light source 6 are arranged above the movable platform 1, and the camera 5 is connected with a computer 7 through a USB interface for image acquisition.

Abstract

The invention discloses a broad leaved plant vein measuring instrument which mainly comprises a movable platform used for placing a leaf piece. A light shading box is arranged above the movable platform. The light shading box is connected with a support. The top part of the light shading box is provided with a light lamp used for changing internal brightness of the light shading box. A video camera and band-shaped light sources are arranged above the movable platform. The video camera is connected with a computer via a USB interface. Supporting wheels are arranged below the movable platform. The supporting wheels are arranged on horizontal guide rails. The movable platform is driven to linearly move along the horizontal guide rails by a lead screw. The lead screw is connected with a stepping motor. The lead screw is connected with the computer. The broad leaved plant vein measuring instrument is generally suitable for broad leaved plants, clean vein structure images can be rapidly and conveniently acquired, and the position of the vein can be accurately identified and length and width of the vein can be estimated so that the broad leaved plant vein measuring instrument can be effectively applied to the scientific research related to the vein.

Description

technical field [0001] The invention relates to the technical field of leaf vein topological structure analysis of plants, in particular to a leaf vein measuring instrument for broad-leaved plants. Background technique [0002] The veins of plant leaves are important organs of leaves and play an important role in judging the development and growth status of plants. The leaf vein connecting the leaf and the leaf stem is called the main vein. Its width is between 0.5-2mm, and it is the only channel for the leaf to obtain nutrition and water from the root; the other end of the main vein reaches the top of the leaf. Viewed from the front, The main vein is a light green thin line (the color of other parts of the leaf is darker than that), slightly curved (approximately straight); viewed from the back of the leaf, the main vein protrudes about 0.1mm-1mm, and the color is the same as that of other parts of the leaf There is little color contrast. The existing method is to directl...
