Problems solved by technology
For the comparison and inspection of linear traces, tool trace experts at home and abroad mostly use the microscope to observe the linear traces artificially to compare the linear traces to judge the degree of coincidence between the thick and continuous lines on the broken surface of the cable (mark bearing body). Huge workload and high subjectivity, often cannot be used as evidence in court

The invention relates to a police linear trace laser detection system, which includes a computer, a controller, a stepping motor drive, an electric slide table, an electronically controlled angle displacement table, a miniature stroke switch, and a high-precision laser displacement sensor , Micro camera. The computer communicates with the controller through USB, and the controller receives the command signal from the computer to control the electric sliding table, the electric control angle displacement table and the high-precision laser displacement sensor; the micro travel switch is installed at both ends of the electric sliding table to control the The high-precision laser displacement sensor provides the computer with high-precision displacement data of the cross-section of the measured object; the microscopic camera provides the computer with an enlarged high-definition image of the measured cross-section to assist in the control of laser detection. The invention combines high-precision laser ranging technology with ingenious optical imaging to realize high-precision detection of cross-sectional traces; the invention is suitable for police linear trace laser detection systems.
Description
technical field [0001] The invention relates to a police linear trace laser detection system, which belongs to the innovation field of police equipment. Background technique [0002] With the rapid development of my country's high-speed railways, various cases of cutting and stealing communication cables and piercing ground wires along the railway lines are on the rise year by year. Such crimes pose a great hidden danger to the safety of high-speed railway transportation and are the key targets of railway public security agencies. The linear traces caused by shearing tools are the most common traces in the cases of piracy along the railway. They are not easily damaged, difficult to disguise, high in occurrence rate, and good in appraisal value. It is of great significance to confirm the suspect. For the comparison and inspection of linear traces, tool trace experts at home and abroad mostly use the microscope to observe the linear traces artificially to compare the linear t...
