Embodiment Construction

[0024] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] The following is attached figure 1 - attached Figure 5 The present invention will be described in further detail.

[0026] A method for non-contact keytooth learning, such as figure 1 shown, including the following steps:

[0027] S1, collecting the first contour point cloud data of the surface of the key by a line laser method;

[0028] S2. Process the first contour point cloud data to obtain first 3D contour information.

[0029] As in the above step S1, the line laser method is to irradiate the surface of the key by emitting the line laser, and the surface of the key reflects the laser to the laser receiving end, and then converts the received reflected laser into a signal to obtain the contour point cloud data information.

[0030] The first 3D contour information in step S2 above includes but is not ...

Abstract

The invention discloses a non-contact key tooth shape learning method and system. The non-contact key shape tooth learning method comprises the following steps that a first contour point cloud data ofa key are collected through a line laser method; and the first contour point cloud data are processed to obtain first 3D contour information. The non-contact key tooth shape learning method and system solve the problems that an existing key making method is poor in versatility, high in environmental requirements, complicated in operation and low in efficiency.

Description

technical field [0001] The invention relates to the technical field of key duplication, in particular to a method and system for non-contact key tooth profile learning. Background technique [0002] During the use of the key, it is generally necessary to copy the key for backup; in the copying of the key, the processing accuracy of the key tooth shape is related to the learning accuracy and the processing accuracy of the key duplicating machine. It directly determines the smoothness of key unlocking and the accuracy of key duplication. [0003] The existing method for learning the tooth shape of a non-contact key uses a group of through-beam photoelectric sensors as the tooth shape measurement scheme. In this technical solution, the opposite-beam photoelectric sensor is fixed on the fuselage, the laser emitting end and the receiving end are arranged oppositely, the key is clamped on the fixture fixture, located in the middle of the pair of photoelectric sensors, and the fix...
