Digital detection device of laser line projector based on linear array ccd

Abstract

The invention discloses a digital detection device for a laser line thrower based on a multi-line array CCD, and relates to a detection device for a laser line thrower. The invention includes a laser line thrower to be inspected, which is provided with a cubic wall, a linear array CCD detector, an area array CCD detector, a serial port HUB and a host computer; 8 high-precision linear array CCDs and 1 area array CCD are used to cooperate. The collection of various detection indicators of the laser line throwing instrument, and the printing, numbering and statistics of the test results can greatly reduce the workload of calibration and detection of the laser line throwing instrument, and at the same time avoid the damage caused to the human eye by visual inspection. The injury and the subjectivity of visual inspection by different inspection personnel make the detection method safe and reliable, and the results are more objective and scientific. The present invention can not only be used for detection and calibration of laser line thrower manufacturers, maintenance departments, etc., but also can be used as a laser line thrower verification standard for quality and technical supervision departments, metrology verification departments, surveying and mapping departments, national defense and military industries and other related industries.

Description

technical field [0001] The invention relates to a detection device for a laser line thrower, in particular to a digital detection device for a laser line thrower based on a linear array CCD. Background technique [0002] The laser line projector is a new type of optomechanical and electrical integration instrument, most of which use 635nm laser diodes, which can project visible red horizontal straight lines and lead vertical lines on the wall. The horizontal or vertical position of the laser projection line can be maintained by using the automatic compensator or long level inside the instrument to manually level. [0003] The laser line instrument generally only provides one horizontal line, called 1H, and there are also 2H and 4H instruments. According to the number of vertical lines, there are 1V, 2V, 3V, and 4V. This is the 1V, 1V1H, 2V1H, 3V1H, 4V1H, 3V2H, 4V2H and other instruments currently on the market. There are also 4V4H abroad, as well as instruments that make a...

Problems solved by technology

At present, there are basically no relevant calibration specifications or standard verification procedures for laser line projectors in China, so the calibration work is mainly carried out according to the factory indicators.
