Embodiment

[0042] When the device is put in place and the mechanical arm is completely moved out of the water surface, the small air bubbles stuck to the wall of the glass tank will float up due to the destruction of the steady state of the water body. If the device has airtightness problems, air bubbles will also be generated. The standard steady-state time of the water body is obtained by the number of floating bubbles, the speed of floating, and the degree of deflection of the bubbles during the floating process.

[0043] When the mechanical arm is completely out of the water surface, the camera is used to collect bubble images. The camera is fixedly installed on one side of the glass tank wall. The camera is facing the tank. The field of view includes the water body and water surface in the glass tank, and the area where the device is placed in the water body; due to the detection When the device is airtight, the liquid level in the cylinder will generally not change much, so the posi...

Abstract

The invention provides a water body steady-state time prediction method based on visual perception, and the method comprises the steps: carrying out the processing of a collected bubble image, obtaining the number of bubbles, the floating speed and the floating deviation degree, and obtaining the shaking degree of a water body based on the number of bubbles, the floating speed and the floating deviation degree; obtaining the standard time required for the water body to reach the steady state according to the water body shaking degree; constructing a steady-state time prediction model based onthe volume of the device, the water inlet speed, the water outlet speed and the speed change degree when the mechanical arm adjusts the pose of the device, fitting the steady-state time prediction model by using a fitting algorithm based on the standard time required for the water body to reach the steady state, and solving an undetermined coefficient in the model. Parameters selected by the steady-state time prediction model are easy to obtain, the data volume and the calculated amount are small when steady-state time prediction is carried out, and the predicted steady-state time is accurate.

Description

technical field [0001] The invention relates to the fields of image processing and air tightness detection, in particular to a method for predicting time of steady state of water body based on visual perception. Background technique [0002] The water immersion method is generally used to detect the tightness of metal devices, that is, put the metal device into a glass cylinder with water, apply air pressure to the cavity of the device, and judge the tightness of the device by observing or detecting whether there are bubbles on the device; and Metal devices are generally placed into the water body of the glass tank by the robotic arm, and the stability of the water body will inevitably be destroyed during the placement process, causing the water body to slosh. Since the sloshing of the water body will interfere with the detection of air bubbles from the air leak hole, it needs to stand for a while Let the water body stop shaking, so that the water body reaches a steady state...
