Embodiment 2

[0022] Embodiment two: see Figure 1 ~ Figure 4 , the present embodiment is an object contour recognition system composed of the infrared light curtain machine for contour recognition and an industrial computer according to Embodiment 1. The reflective light curtain 2 of the infrared light curtain machine, the transmission light curtain transmitter 3 and the transmission light curtain receiver 4 output signals are connected to the decoder, and the decoder transmits the processed real-time data to the industrial computer through the serial port, and the industrial computer passes The software processing system establishes three-dimensional coordinates, regards the height direction of the object as the Z axis, regards the width direction of the object as the Y axis, and regards the moving direction of the object as the X axis to realize the uniform speed passing through the door frame of the light curtain machine Three-dimensional contour recognition and intelligent measurement ...

Embodiment 3

[0023] Embodiment 3: This embodiment is a method for object contour recognition using an infrared light curtain machine. The object contour recognition system composed of an infrared light curtain machine for contour recognition and an industrial computer as described in Embodiment 1 is used. The infrared light curtain machine is installed on the orbit of the object, using the principle of active three-dimensional contour measurement and three-coordinate measuring machine, the orbit of the object is regarded as a three-dimensional space,

[0024] 1) For objects moving at a constant speed inside the gantry, the horizontal light curtain machine uses the principle of time amplifier to judge whether the object is blocked, and records the coordinates of the point blocked by the object, and the decoder receives the real-time specific data of the blocked object. And pass the data to the industrial computer through the serial port;

[0025] 2) The industrial computer receives the real...

Abstract

The invention relates to an article contour recognition device and method. An infrared light curtain machine for contour recognition comprises a door frame, a reflection light curtain and a transmission light curtain, wherein the transmission light curtain comprises a transmitter and a receiver; the reflection light curtain is transversely mounted above the door frame; the transmitter of the transmission light curtain is mounted on one side of the vertical direction of the door frame, and the receiver of the transmission light curtain is mounted on the other side; and the output signals of the reflection light curtain, the transmitter of the transmission light curtain and the receiver of the transmission light curtain are connected into a decoder. In the article contour recognition system and method, the output signals of the reflection light curtain of the infrared light curtain machine and the transmitter and receiver of the transmission light curtain are connected into the decoder; the decoder transfers the treated real-time data to an industrial control machine through a serial port; the industrial control machine establishes three-dimensional coordinates through a software treatment system; and the height direction of an article is regarded as a Z axis, the width direction of the article is regarded as a Y axis, and the moving direction of the article is regarded as an X axis so as to realize three-dimensional contour recognition and intelligent measurement of the size of the article passing through the door frame of the light curtain machine at a constant speed.

Description

technical field [0001] The invention relates to a sensor device and an object contour recognition system for object contour recognition, in particular to an infrared light curtain machine for contour recognition and its object contour recognition system and method. Background technique [0002] The three-dimensional morphological feature of an object is one of the most important features used to describe an object. The purpose of object contour recognition is to detect the three-dimensional size of the object, and apply the corresponding algorithm to draw the three-dimensional contour map of the object through computer software. [0003] People have been studying the application of various optical methods to measure the three-dimensional surface shape of objects. The basic methods for obtaining the three-dimensional contour size of objects can be divided into two categories: passive contour measurement and active three-dimensional contour measurement. The passive three-dim...
