Projector apparatus for improving recognition efficiency in judicial evidence system

Abstract

The invention provides a projector apparatus for improving the recognition efficiency in a judicial evidence system, and belongs to the field of judicial evidence marking. The projector apparatus comprises a shell; a master control module, a display module, a projection module, and a power supply module arranged in the shell; and a power switch, a setting button, and a light-outlet hole arranged on the shell. The master control module is separately connected with the display module, the projection module, the power supply module and the setting button, the power switch is connected with the power supply module, and the master control module can project content displayed by the display module from the light-outlet hole through the projection module. The beneficial effects of the projector apparatus are that the structure is simple, convenience and practicality are achieved, a unique recognition code can be projected to each physical evidence and is associated with the evidence during investigation and evidence collection, and information acquisition, physical evidence tracing, and onsite analysis and case connection and combination in the age of big data are facilitated.

Description

technical field [0001] The invention relates to the field of judicial evidence marking, in particular to a projector device for improving recognition efficiency in a judicial evidence system. Background technique [0002] All kinds of physical evidence will be extracted during the on-site investigation. It is the basic work of judicial evidence to take pictures of each physical evidence and label them with Chinese characters. The usual practice is to use the already made plastic identification plate to place around the physical evidence for taking pictures, even without any identification, just take detailed photos of the physical evidence. This will lead to insufficient recognition when dealing with a large number of detail photos, which is easy to be confused; when describing the physical evidence, only words can be used to indicate the extracted parts and features, etc., which is not concise enough and easy to repeat; when the sign is placed, it is easy to destroy the sce...

AI Technical Summary

Problems solved by technology

The relationship between physical evidence is becoming more and more responsible. Continuing to use the current method of describing on-site physical evidence in words will result in inefficient use of information. Only marking the unique identity feature for on-site physical evidence is the key to solving the problem
