Image processing methods and apparatuses, computer readable storage media, and electronic devices

A non-transitory computer readable storage medium having stored thereon computer programs executed by a processor to carry out:

• in response to detecting that a camera component is turned on, controlling the camera component to collect a speckle image of an object that is illuminated with laser speckles;
• detecting a current temperature of the camera component;
• acquiring a reference image with reference depth information based on the current temperature and a preset correspondence between reference images and specified temperatures, comprising:
• acquiring differences between the current temperature and each specified temperature;
• and
• acquiring the reference image corresponding to the specified temperature with the smallest difference;
• calculating based on the speckle image and the acquired reference image to acquire a depth image;
• and
• establishing the preset correspondence between reference images and specified temperatures, comprising:
• controlling a temperature of the camera component to reach each specified temperature;
• controlling the camera component to collect a reference image under each specified temperature;
• and
• establishing the correspondence between the specified temperatures and the reference images.

An electronic device comprising a memory and a processor, the memory storing computer readable instructions, the computer readable instructions being executed by the processor, causing the processor to:

• in response to detecting that a camera component is turned on, control the camera component to collect a speckle image of an object that is illuminated with laser speckles;
• detect a current temperature of the camera component;
• acquire a reference image with reference depth information based on the current temperature and a preset correspondence between reference images and specified temperatures, comprising:
• acquire differences between the current temperature and each specified temperature;
• and
• acquire the reference image corresponding to the specified temperature with the smallest difference;
• calculate based on the speckle image and the acquired reference image to acquire a depth image;
• and
• establish the preset correspondence between reference images and specified temperatures, by actions of:
• controlling a temperature of the camera component to reach each specified temperature;
• controlling the camera component to collect a reference image under each specified temperature;
• and
• establishing the correspondence between the specified temperatures and the reference images.
