Method of exciting thermal radiation feature of solid object and recognition auxiliary device

Abstract

The invention discloses a method of exciting the thermal radiation feature of a solid object and a recognition auxiliary device. As for the method, the solid object to be recognized is heated through a thermal convection mode to excite the thermal radiation feature of the solid object to be recognized. The recognition auxiliary device comprises a tank body which is internally provided with a thermal insulation cavity; the thermal insulation cavity is internally provided with a heating component used for supplying heat and an airflow power device used for controlling an airflow direction; and the tank body is provided with an air inlet and an air outlet. The recognition auxiliary device adopts the thermal convection mode to supply effective recognition condition for visual recognition. The method of exciting the thermal radiation feature of the solid object and the recognition auxiliary device provided by the invention are stable in output, good in recognition consistency and strong in interference resistant capability and cannot generate rays harmful to a human body at the same time.

Description

technical field

[0001] The invention relates to the technical field of machine vision recognition, in particular to a method for stimulating thermal radiation characteristics of a solid object and a recognition auxiliary device. Background technique

[0002] The existing typical auxiliary means of visual recognition is the use of light sources. Light source is an important factor affecting machine vision recognition input, it will directly affect the quality of input data and application effect. Since there is no universal machine vision lighting equipment, it is necessary to select the corresponding lighting device for different machines to achieve the best effect.

[0003] Many industrial machine vision identifications use visible light as a light source, mainly because visible light is readily available, low cost, and easy to operate. Commonly used visible light sources include incandescent lamps, fluorescent lamps, mercury lamps, sodium lamps, and LED lamps.

Embodiment 1

[0053] refer to figure 1 , in this embodiment, a method for stimulating thermal radiation characteristics of a solid object is proposed, including:

[0054] Step S1: Determine the solid object to be identified;

[0055] Step S2: The solid object to be identified is heated by thermal convection, so as to excite the thermal radiation characteristics of the solid object to be identified.

[0056] refer to figure 2 and image 3 , based on the method for stimulating the thermal radiation characteristics of solid objects proposed above, in this embodiment, an identification auxiliary device is also proposed. . Specifically, a heat insulating material may be provided on the box body 100 . The thermal insulation chamber 1000 is kept isolated from the external environment without heat exchange, so that the interior of the thermal insulation chamber 1000 can maintain a constant temperature. At the same time, the shell of the box body 100 does not generate heat, which makes it saf...
