[0002] Line laser scanning uses a line laser to scan the object to be measured, and uses a camera to collect the deformed laser line on the surface of the object to be measured for analysis and measurement. It is very useful in many application fields: such as measurement, imaging, manufacturing, positioning, and visual obstacle avoidance.

[0003] In the laser scanning process of the existing measurement platform, a default scanning speed is generally used, or the user tries to modify a scanning speed. After starting the laser scanning, it is checked whether a sufficient amount of laser sampling data is obtained. If laser sampling data is lost, the scanning speed needs to be reduced.

[0068] S3. According to the third data and the fourth data, and in combination with the second data, matching processing is performed to generate fifth data corresponding to the continuous trigger scanning of the line laser; wherein the fifth data is the scanning speed data after the line laser is adjusted.

[0069] The generating and acquiring, based on the first data, second data, third data and fourth data corresponding to the line laser continuous trigger scanning respectively, further includes:

[0070] S21, creating an exposure mode corresponding to line laser scanning, and generating corresponding sixth data according to the exposure mode; wherein the sixth data is line laser scanning exposure mode data;

[0071] S22, based on the second data, generating seventh data and eighth data corresponding to the line laser scanning; wherein the seventh data is the laser internal parameter state control data; the eighth data is the laser Z direction measurement range data;

[0072] S23. Adjust and process the third data in real time according to the sixth data, the seventh data and the eighth data.

[0073] The step of generating seventh data and eighth data corresponding to line laser scanning based on the second data further includes:

[0074] S221, based on the seventh data, determining whether to generate first control data; wherein the first control data is laser frequency interference processing control data;

[0075] S222. Based on the seventh data, generate second control data, third control data and fourth control data corresponding to the line laser scanning respectively; wherein the second control data is laser brightness output control data; the third control data is stray light suppression function control data; and the fourth control data is image position deviation correction control data.

[0076] The generating, based on the seventh data, second control data, third control data and fourth control data corresponding to the line laser scanning respectively, further comprises:

[0077] S2221, generating and acquiring ninth data corresponding to the object to be scanned by the laser line, and determining whether tenth data exists according to the ninth data; if so, executing the next step; otherwise, terminating the next step; wherein the ninth data is image position data corresponding to the object to be scanned by the laser line; and the tenth data is image position deviation data;

[0078] S2222. Based on the ninth data and in accordance with the fourth control data, correct and process the tenth data in real time.

[0079] The generating and acquiring, based on the first data, second data, third data and fourth data corresponding to the line laser continuous trigger scanning respectively, further includes:

[0080] S24, generating and acquiring eleventh data corresponding to the measuring platform; wherein the eleventh data is pulse signal data corresponding to the encoder of the measuring platform;

[0081] S25. Based on the eleventh data, generate fourth data corresponding to the measurement platform in real time.

[0083] S31. Calculate and generate twelfth data corresponding to the line laser continuous trigger scanning based on the third data and the fourth data; wherein the twelfth data is the maximum scanning speed of the laser continuous scanning.

[0084] Specifically, in an embodiment of the present invention, a calculation method for automatically matching the maximum scanning speed according to the scanning parameters set by the user is provided. Specifically, in the calculation and processing process, the laser frequency is the laser sampling period, which is determined by the laser internal parameters such as exposure mode, interference processing, brightness output, stray light suppression function, image position deviation correction and the Z-direction measurement range; the scanning interval is the distance moved by the measuring platform during each laser sampling interval, and the scanning interval is determined by the pulse signal output by the measuring platform encoder; and the scanning speed = frequency * scanning interval. Since the encoder generally has some errors, it is empirically measured that the maximum error will not exceed 20%. The maximum scanning speed of the laser continuous scanning used is frequency * scanning interval * 0.8.

[0085] That is to say, in the scheme of the present invention, according to the laser sampling frequency and scanning interval set by the user, the system automatically calculates the maximum scanning speed of laser continuous scanning, and the calculation method is: laser sampling frequency * scanning interval * 0.8. For example, the laser frequency is 4KHz, that is, the laser samples 4000 times per second, and the interval distance of the pulse output of the measuring platform encoder is 0.05 mm, that is, the maximum scanning speed = 4000*0.05 (mm / s) * 0.8 = 160 (mm / s).

[0086] In a specific embodiment, through the solution of the present invention, a first preset distance corresponding to the scanning interval is generated and obtained, for example, it is set to 0.005 mm (specific parameters are shown in the attached Figure 3 The scan is completed. Figure 4 The product shown in the figure takes 5.7 seconds; if the second preset distance corresponding to the scanning interval is generated and obtained, for example, it is set to 0.05 mm (specific parameters are shown in the attached Figure 5 The scan is completed. Figure 6 The product shown takes 2.2 seconds; that is, when different preset distance data are generated and obtained, that is, after the laser scanning point interval is modified, it runs automatically, and the measurement platform adapts to the scanning speed. The total time for scanning the same product is reduced from 5.7 seconds to 2.2 seconds, indicating that the corresponding scanning speed is adaptively changed during the laser scanning process through the solution of the present invention.
