Problems solved by technology

[0003] For example, the vein enhancement imager projects the image of human veins onto the skin surface, which helps medical staff to find the vein to be punctured. Only when certain requirements are met can the optimal imaging effect be achieved. At present, only relying on the eyes and experience of medical staff to judge, due to subjective differences, will lead to certain errors

Abstract

The invention discloses a positioning device and a positioning method of a handheld imaging system. The imaging system is provided with at least three groups of laser diodes, each laser diode group comprises at least two laser diodes, the included angle between laser rays emitted by the two laser diodes of each group is regulated, the intersection point of each laser diode group is located on a preset imaging surface, three or more groups of laser diodes are irradiated to an imaged object, the distance and angle of the imaging system relative to the imaged object are regulated, and when the two laser rays of each group are intersected on the imaged object to become a point, the fact that the distance and angle between the imaging system and the imaged object reach preset values is indicated, and the best imaging result is obtained.

Description

Technical field [0001] The invention relates to an imaging positioning method, in particular to a positioning device and a positioning method of a handheld imaging system. Background technique [0002] For handheld imaging systems, when imaging, there are strict requirements on the distance and angle of the imaging system relative to the imaged object. If it deviates from the preset position, it will produce obvious deviations, while handheld imaging devices often lack clear Determine whether the correct imaging position is reached. [0003] For example, the vein-enhanced imager projects the human vein image onto the skin surface, which helps medical staff find the vein to be punctured. However, it is required to place the vein-enhanced imager directly above the imaging position and the distance from the imaging position. The optimal imaging effect can only be achieved when certain requirements are reached. At present, the judgment is only based on the eyes and experience of medic...
