Projection method of high-pixel projection lamp and related device

The invention discloses a projection method of a high-pixel projection lamp and a related device, and relates to the field of software, and the method comprises the steps: firstly determining a target projection pattern; a space rectangular coordinate system where the target chip is located is established, and the target projection pattern is converted to the space rectangular coordinate system; and further performing projection conversion and pixel calculation on the target chip by taking the target projection pattern as a target under the space rectangular coordinate system to obtain a chip end pixel pattern of the target chip. The target projection pattern is converted to the space rectangular coordinate system where the chip is located, the chip end pixel pattern of the projection module in any installation position and installation direction can be generated, and the chip end pixel pattern can be used for a picture at a light source end or a chip end and serves as an input source of a picture driving cod
