Shot blasting machine shot blasting angle and speed detection method based on two-dimensional vision

Abstract

The invention relates to a shot blasting machine shot blasting angle and speed detection method based on two-dimensional vision. The shot blasting angle detection method comprises the following steps:S1, when an optical fiber sensor module detects that a right projectile passes through a screening piece hole, starting timing, and when the projectile reaches a plane plate of a scale body, startingtransverse and longitudinal high-speed camera modules for photographing; S2, uploading photographed images, and performing trimming, filtering and eigenvalue calculation on the images; and S3, solving a projectile ejection angle, the formula being as follows: alpha=arctan (x1 / h1), beta=arctan(y1 / h1), wherein in the formula, alpha is the transverse projectile projection angle, beta is the longitudinal projectile projection angle, x1 is the transverse projectile offset distance at the shooting moment, y1 is the longitudinal projectile offset distance at the shooting moment, and h1 is the vertical distance from the projectile to the screening piece at the shooting moment.

Description

technical field [0001] The invention belongs to the technical field of shot blasting machine detection equipment, and in particular relates to a two-dimensional vision-based detection method for projectile projection angle and velocity of a shot blasting machine. Background technique [0002] The shot blasting machine is a mechanical device that uses a high-speed rotating impeller to throw shot and sand, and hits the surface of the part at high speed to meet the requirements of surface treatment. The treated shot and sand metal have improved wear resistance, corrosion resistance and aesthetics, and at the same time enhance the adhesion and uniformity of spraying. Different metal workpieces have different processing standards, which requires knowing the parameters of different shot blasting machines and different projectiles, such as projectile force, spray angle, projectile speed, and projectile time, in order to achieve high-efficiency shot blasting. Projectile projectile ...
