TECHNICAL FIELD

[0002] In the prior art, the light source on the market has the following problems: first, the light source controller is relatively single, and when multiple angles and multiple spectrums of a measured object need to be photographed multiple times, the wiring is complex and the control mode is complex; second, when taking pictures at different angles at the same position, the light source controller has slow switching speed and is prone to errors; and third, when the measured object is replaced, the light source controller needs to be reconnected to the control signal line due to changes in the control scheme, which is time-consuming and laborious; the above problems collectively result in reduced detection efficiency and algorithm efficiency of the light source, and the production capacity cannot be improved.

[0003] In view of the problems of low detection efficiency and algorithm efficiency of the existing light source in the related art, there is still a lack of a better technical solution. SUMMARY

Check again for a valid external trigger signal; if not, wait for a trigger signal; if a trigger signal is present, proceed to the next step. S35. Execute all data parameters in the next combination and proceed to the next step; S36. Check if all data parameters in this combination have been executed; if not, wait for all parameters in this combination to be executed; if executed, proceed to the next step. S37. Check whether all the combined data parameters to be executed have been executed; if not, return to step S34 to perform trigger signal detection again; if the execution has been completed, return to the initial state of step S31. S4. Select multiple combined cyclic execution modes based on the light source usage requirements of irradiating multiple detection points one by one. S41. Detect whether there is a valid trigger signal externally; if there is no trigger signal, wait for the trigger signal; if there is a trigger signal, proceed to the next step. S42. Execute all data parameters in combination 1 and proceed to the next step; S43. Check if all data parameters in this combination have been executed; if so, proceed to the next step; otherwise, wait for all data parameters in this combination to be executed. S44. Execute all data parameters in the next combination and proceed to the next step; S45. Check if all data parameters in this combination have been executed; if not, wait for all data parameters in this combination to be executed; if executed, proceed to the next step. S46. Check whether all data parameters in the required combination have been executed. If not, return to step S43 to perform trigger signal detection again. If the execution has been completed, return to the initial state in step S41.

[0006] The beneficial effects of this invention are: the design of this application is reasonable, and it solves the problems of diverse test objects, such as taking pictures from multiple angles simultaneously, sequentially, and continuously, and quickly switching the required light source parameters, so as to meet the diversity of test objects, adapt to more scenarios, and achieve the effect of rapid line change detection by simply adjusting the control parameters, which greatly saves time and manpower and reduces the difficulty of equipment line change detection.
