A method and device for measuring breeding targets

Abstract

The invention provides a method and device for measuring a harvested and cultivated target, and the method comprises the steps: determining a target object in an obtained target image and the actual position information of the target object based on the visual features of the target object; acquiring first point cloud data of the target object based on the actual position information and preset acquisition position information on the target object; based on the first point cloud data, determining a first tangent point position and a second tangent point position where the collection position is tangent to two opposite sides of the target object, a first length of a first connecting line between the first tangent point position and the collection position, a second length of a second connecting line between the second tangent point position and the collection position, and a first included angle between the first connecting line and the second connecting line; and based on the first length of the first connecting line, the second length of the second connecting line and the first included angle between the first connecting line and the second connecting line, determining the diameter at breast height of the target object at the collection position.

Description

technical field [0001] The present application relates to the technical field of forest harvesting and cultivation, and in particular, to a measuring method and a measuring device for harvesting and cultivation targets. Background technique [0002] With the rapid development of forestry-related industries, a large number of trees in artificial fast-growing forests need to be felled in many cases. However, for the sustainable development of the forestry industry, every tree that is felled must meet certain standards, that is to say, the felled trees must meet certain standards. Each tree needs to meet certain specifications, such as the diameter at breast height of the tree to be felled, which can only be determined after manual measurement and screening. [0003] However, due to the complex forest environment and many obstacles, the measurement environment that the operator can reach is very limited. Usually, the complex forest environment will make the harvesting work inte...

Problems solved by technology

[0003] However, due to the complex forest environment and many obstacles, the measurement environment that operators can reach is very limited. Usually, the complex forestry environment will make the harvesting work intermittent. In some environments, for example, areas where natural disasters such as earthquakes and floods occur , or in some rough terrain environments, it is not conducive to manual measurement, and it may even bring danger to the operator, which is not conducive to the measurement of trees, and the work efficiency is low
