Problems solved by technology

[0005] At present, the measurement of plant fruit mainly uses the contact measurement method based on linear displacement sensor. The shortcoming of the contact measurement device is that it is in contact with the surface of the fruit during measurement, which will affect the norm...

Embodiment

[0052] Embodiment: A visual detection system for micro-size changes of plant fruits, including an image acquisition device 1, an image processing and control device 2, a support device and an external trigger device 3, and the support device is used to support the fruit. The image acquisition device includes a CMOS industrial camera, a tripod, a telecentric lens and a red backlight source. The supporting device is a fixed frame constructed of stainless steel, and the supporting surface of the fixed frame is used to support the target fruit and prevent the fruit from moving. The external trigger device is a hardware device that controls the image acquisition of the CMOS industrial camera to support the timing acquisition of fruit growth images. When the image acquisition device is installed, the CMOS camera is fixed on the tripod, and the position of the camera is changed by the tripod to ensure that the optical axis of the camera is perpendicular to the target fruit placed on ...

Abstract

The invention discloses a visual inspection system and method for scale micro changes of plant fruits. The visual inspection system comprises an image collection device, an image processing and controlling device, a supporting device and an external trigger device. After images of the plant fruits are collected, denoised, computed and converted into binary images, the diameters of the fruits are obtained. By means of the system, the scale micro changes of the plant fruits can be detected in a non-contact and high-accuracy mode, and normal growth of the scale micro changes of the plant fruits will not be affected. The visual inspection system and method for the scale micro changes of the plant fruits can be widely applied to the aspects such as searching of plant growth rules, growth abnormity detection, water-saving irrigation and production optimum control.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a system and method for visually detecting changes in the micro-size of plant fruits. Background technique [0002] The problem of water resources has been paid attention to by many countries and regions, and the problem of water conservation has always been a hot spot in agricultural research at home and abroad. In my country, agricultural water consumption accounts for about 70% of the total water consumption of the national economy, and with the rapid development of my country's economy, urban and industrial water use is increasing, and the amount of agricultural water available is decreasing. Therefore, research and analysis to improve water utilization and water conservation Technology is of great significance for achieving sustainable development of the national economy and ensuring food and water security in our country, and it is also an important part of building ...
