Image acquisition method and apparatus, computer device, and storage medium

A computer device, comprising a memory and a processor, the memory having a computer program stored therein that, when executed by the processor, causes the computer device to perform an image acquisition method including:

• displaying a mapping pattern corresponding to a key area of a target part of a target object in response to a pattern display operation triggered by the target object;
• changing a display state of the currently displayed mapping pattern when a relative position of the target part relative to an image acquisition element changes, further including:
• obtaining at least three effective distances corresponding to the key area of the target part by using at least three distance sensors when the target part is within an acquisition range of the image acquisition element, wherein the at least three distance sensors are evenly distributed around the image acquisition element;
• constructing a virtual plane of the key area based on the at least three effective distances;
• determining a relative posture of the key area based on a relative angle between the virtual plane and a standard plane;
• and
• adjusting the display state of the mapping pattern based on the relative posture;
• and
• acquiring a key area image of the target part contactlessly by using the image acquisition element when the currently displayed mapping pattern matches a preset recognition pattern.

A non-transitory computer-readable storage medium, having a computer program stored thereon that, when executed by a processor of a computer device, causes the computer device to perform an image acquisition method including:

• displaying a mapping pattern corresponding to a key area of a target part of a target object in response to a pattern display operation triggered by the target object;
• changing a display state of the currently displayed mapping pattern when a relative position of the target part relative to an image acquisition element changes, further including:

• constructing a virtual plane of the key area based on the at least three effective distances;
• determining a relative posture of the key area based on a relative angle between the virtual plane and a standard plane;
• and
• adjusting the display state of the mapping pattern based on the relative posture;
