The invention discloses a material detection method, which is applied to an assembly line and is based on a TOF handheld terminal. The method includes the following steps: a. Setting the frequency and exposure time of a camera of the TOF handheld terminal, and obtaining the reflected light of the infrared light emitted by the transmitter. Vector value; b. The transmitter emits infrared light to the measured object on the assembly line to collect the image of the measured object; c. Obtain the characteristic parameters of the measured object according to the image of the measured object; d. The characteristic parameters are compared with the characteristic parameters in the database. The material detection method of the invention can conveniently and quickly realize the collection of material characteristics on the assembly line, and can accurately and quickly analyze and determine the material detection result, thereby improving the efficiency of material detection.
Description
technical field [0001] The invention relates to the field of material classification and identification, and more particularly to a material detection method based on a TOF handheld terminal used in an assembly line. Background technique [0002] With the continuous advancement of science and technology, the recognition of object materials has gradually become a hot spot, and material classification is a technology that is commonly used in computer vision applications but is difficult to achieve. With the further development of robotics and human-computer interaction, the demand for more accurate material classification will grow rapidly, especially for the automated inspection of industrial assembly lines, and more intelligent inspection methods are urgently needed to match its highly automated needs. [0003] Although existing computer vision techniques, such as semantic segmentation and object recognition, can play a role in material classification applications. But one ...
